Detailed Description

The embodiment of the specification provides a method, a device and equipment for processing offline transactions.

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.

Example one

As shown in fig. 1, an execution body of the method may be a terminal device, where the terminal device may be a mobile terminal device such as a mobile phone, a tablet computer, or the like, or a computer device such as a notebook computer or a desktop computer, and the terminal device may be a device used by a merchant (i.e., a target party of a transaction) for settling a commodity purchased by a user, or a device used by a transaction initiator. The terminal device may be provided with a trusted Execution environment, where the trusted Execution environment may be a tee (trusted Execution environment), and the trusted Execution environment may be implemented by a program written in a predetermined programming language (that is, may be implemented in the form of software), or may be composed of a designated hardware device and corresponding software, and the trusted Execution environment may be a secure operating environment for performing data processing. The method may specifically comprise the steps of:

in step S102, when the transaction information of the target transaction in the offline transaction scenario is acquired, the transaction information of the target transaction is stored in the trusted execution environment.

The offline transaction scenario may be a scenario in which both the terminal devices used by the two parties of the transaction are in an offline state (i.e., not connected to the network or not connected to the network), or a scenario in which both the parties of the transaction are in an offline state. The target transaction may be any transaction, for example, a user purchases a certain commodity in an offline store opened by a certain merchant, and the user settles the purchased commodity and the merchant through a payment application installed in a terminal device of the user, so as to form a transaction. The transaction information may include a plurality of different information, for example, the transaction information may include an identifier of a target transaction, a resource amount of the transaction (specifically, a transaction amount, etc.), account information of both parties of the transaction, and the like. The trusted execution environment may be a TEE, and the trusted execution environment of the TEE may be a data processing environment that is secure and isolated from other environments, i.e., processes executed in the trusted execution environment, and data generated during data processing, etc., may not be accessible to other execution environments or applications outside the executable environment. The trusted execution environment of the TEE may be implemented by creating a small operating system that may run independently in a trusted zone (e.g., TrustZone, etc.), and the TEE may directly provide services in the form of system calls (e.g., handled directly by the TrustZone kernel). The terminal device may include an REE (rich execution environment) and a TEE, an operating system installed in the terminal device may be run under the REE, such as an Android operating system, an iOS operating system, a Windows operating system, a Linux operating system, and the like, and the REE may have characteristics of strong function, good openness and extensibility, and may provide all functions of the terminal device, such as a camera function, a touch function, and the like, for an upper application program. The TEE has its own execution space, that is, there is an operating system under the TEE, the TEE has a higher security level than the REE, software and hardware resources in the terminal equipment which can be accessed by the TEE are separated from the REE, but the TEE can directly acquire the information of the REE, and the REE cannot acquire the information of the TEE. The TEE can perform authentication and other processing through the provided interface, so that user information (such as payment information, user privacy information and the like) cannot be tampered, passwords cannot be hijacked, and information such as fingerprints or faces cannot be stolen.

In implementation, under the condition that the network cannot be connected, the use of offline transaction is an important supplement to network transaction, and especially under some specific scenes (such as basements, remote mountainous areas, planes, and the like), different from a normal transaction process, that is, a transaction sheet (such as a bill or an order and the like) corresponding to transaction information related to the transaction is generated in real time at a service end, so that both the reliability and the stability of the transaction are greatly guaranteed, while for offline transaction (especially for transaction performed when terminal devices of both parties of the transaction are in an offline state), a corresponding transaction sheet needs to be generated in terminal devices of both parties of the transaction, and when the terminal devices are reconnected to the network, the transaction sheet is sent to the service end for processing. Because the transaction information may be simultaneously present in the terminal devices of the two parties to the transaction, if some reasons cause inconsistency of the transaction information in the terminal devices of the two parties to the transaction, or the transaction information is lost, or the terminal device is in an offline state for a long time (i.e., for a time greater than a preset time threshold), the transaction may not be traceable, thereby causing transaction disputes and resource loss, so that the transaction security is low. The embodiment of the present specification provides an implementable technical solution, which may specifically include the following contents:

for the terminal device of the transaction initiator, the transaction initiator may select a transaction object that needs to perform a transaction (for example, the transaction initiator may select a commodity that needs to be purchased in an off-line shop), and after the selection is completed, the selected object may be provided to a manager for settlement, and the manager may calculate the transferred resource (for example, the amount of money that needs to be paid, etc.) that is needed by the selected object. After the calculation is completed, the transaction initiator may provide information of the account for resource transfer to the administrator through the terminal device of the transaction initiator, and the manner of providing information by the terminal device of the transaction initiator may include a plurality of different manners, for example, information of the account for resource transfer may be provided to the administrator through a graphic code (which may be a barcode or a two-dimensional code, etc.), or information of the account for resource transfer may be provided to the administrator through a fingerprint, a voiceprint, a facial image, etc., which may be specifically set according to an actual situation, and this is not limited in this description embodiment. The terminal device of the transaction target party can acquire the information of the account, acquire the transaction information of the target transaction and send the transaction information to the transaction initiator for confirmation, and at the moment, the terminal device of the transaction initiator can acquire the transaction information of the target transaction and store the transaction information of the target transaction in a trusted execution environment of the terminal device of the transaction initiator.

For the terminal device of the transaction target party, based on the above process, the transaction initiator can select the object to be transacted, and then, the selected object can be provided to the manager for settlement, and the manager can calculate the resource to be transferred for the selected object. The transaction initiator can provide the account information of resource transfer to the manager through the terminal device of the transaction initiator, the terminal device of the transaction target can acquire the account information, meanwhile, the terminal device of the transaction target can also acquire the transaction information of the target transaction, and the transaction information of the target transaction can be stored in the trusted execution environment of the terminal device of the transaction target. It should be noted that, in the above case, the terminal device of the transaction destination may perform a pre-transfer process of resources (specifically, pre-deduction, etc.) to prevent the double flower from occurring.

In step S104, a transaction status flag of the target transaction is generated in the trusted execution environment, and is set as in-transaction, and in the case that the target transaction is completed, the transaction status flag of the target transaction in the trusted execution environment is set as transaction complete by in-transaction.

The transaction state flag may be used to mark information of a transaction state of a target transaction, and the transaction state flag may include a plurality of different presentation manners, for example, the transaction state flag may be presented in a data tag manner, or may also be presented in a manner of setting a state bit, where different information (such as numbers, letters, and the like) may be set in the state bit, the set information is different, and corresponding transaction states may be different, for example, a state bit of 0 indicates that the transaction state is in transaction, and a state bit of 1 indicates that the transaction state is completed, and the like.

In implementation, after the transaction information of the target transaction is stored in the trusted execution environment of the terminal device in the above manner, a transaction status flag (i.e. a transaction status flag of the target transaction) may be generated for the transaction information of the target transaction in the trusted execution environment, and at this time, since the target transaction is not completed yet, the transaction status flag of the target transaction may be set to be in transaction.

After the terminal device stores the transaction information of the target transaction in the trusted execution environment, the terminal device of the transaction target party can send the transaction information of the target transaction or information (such as an order and the like) related to the transaction information to the transaction initiator, the transaction initiator can determine whether the received information is wrong, if no, the transaction initiator can send a confirmation notice to the transaction target party through the terminal device of the transaction initiator, after the terminal device of the transaction target party receives the confirmation notice, resource transfer processing can be carried out based on the transaction information of the target transaction and the information of the account of resource transfer provided by the transaction initiator, after the resource transfer is successful, the target transaction can be determined to be completed, at this time, the terminal device of the transaction target party can set the transaction state flag of the target transaction in the trusted execution environment as transaction completion from the transaction, and in addition, the terminal device of the transaction initiator may also set a transaction status flag of the target transaction in the trusted execution environment from the transaction to transaction complete.

In step S106, a transaction clearing process having a preset clearing validity period is performed on the target transaction based on the transaction information of the target transaction and the information of the transaction status flag of the target transaction.

The clearing validity period may be a period in which both transaction parties initiate transaction clearing processing for a certain transaction, and the clearing validity period may include multiple types, for example, 3 days, 7 days, or 14 days, and may be set according to actual conditions, which is not limited in this description embodiment, and for a certain transaction, if both transaction parties initiate transaction clearing processing for the transaction within the clearing validity period, the transaction can be cleared, and if both transaction parties do not initiate transaction clearing processing for the transaction within the clearing validity period, the transaction clearing processing for the transaction can be refused, where the transaction clearing processing for the transaction can be performed by a terminal device of a transaction target party, or performed by another device (as shown in fig. 2) other than both transaction parties, and may be set according to actual conditions, the examples in this specification do not limit this.

In implementation, as shown in fig. 2, if the transaction status flag of the target transaction is transaction completion, a clearing process may be initiated at the transaction initiator and/or the terminal device of the transaction target based on the transaction information of the target transaction and the information of the transaction status flag of the target transaction, at this time, it may be determined whether the target transaction is within the clearing validity period based on the transaction time and other information in the transaction information of the target transaction, if so, a transaction clearing process with a preset clearing validity period may be performed on the target transaction based on the transaction information of the target transaction and the information of the transaction status flag of the target transaction, and if not, the transaction clearing process on the target transaction may be rejected.

The embodiment of the specification provides a processing method of an offline transaction, which is applied to a terminal device, wherein the terminal device is provided with a trusted execution environment, under the condition that transaction information of a target transaction under an offline transaction scene is acquired, the transaction information of the target transaction is stored in the trusted execution environment, a transaction state flag of the target transaction is generated in the trusted execution environment, the transaction state flag of the target transaction is set to be in transaction, under the condition that the target transaction is completed, the transaction state flag of the target transaction in the trusted execution environment is set to be transaction completed in the transaction, and finally, transaction clearing processing with a preset clearing validity period can be executed on the target transaction based on the transaction information of the target transaction and the information of the transaction state flag of the target transaction, so that the offline transaction is cleared based on the clearing validity period and the transaction state flag, therefore, the generation of transaction disputes can be effectively avoided, the loss of resources is reduced, and the transaction safety and the transaction experience are improved.

Example two

As shown in fig. 3, an execution body of the method may be a terminal device, where the terminal device may be a mobile terminal device such as a mobile phone and a tablet computer, or a computer device such as a notebook computer or a desktop computer, and the terminal device may be a device used by a merchant (i.e., a target party of a transaction) for settling a commodity purchased by a user, or a device used by a transaction initiator. The terminal device may be provided with a trusted execution environment, which may be a TEE, and the trusted execution environment may be implemented by a program written in a predetermined programming language (i.e., may be implemented in the form of software), or may be composed of a designated hardware device and corresponding software, and may be a secure operating environment for performing data processing. The method may specifically comprise the steps of:

in step S302, when the transaction information of the target transaction in the offline transaction scenario is acquired, the transaction information of the target transaction is stored in the trusted execution environment.

In step S304, a transaction status flag of the target transaction is generated in the trusted execution environment, and the transaction status flag of the target transaction is set to be in-transaction.

The transaction state flag of the target transaction is set in the transaction information of the target transaction, for example, a state bit may be set in the transaction information of the target transaction, and different transaction states may be represented by different numbers in the state bit, for example, if the state bit is 0, the transaction state is in transaction, and if the state bit is 1, the transaction state is transaction completion, and the like.

In step S306, a transaction completion message of the target transaction provided by the terminal device is acquired, and a notification message of transaction completion of the target transaction provided by another party of the target transaction is acquired.

If the terminal device is a terminal device of a transaction initiator, the other party of the target transaction can be a transaction target party, and if the terminal device is a terminal device of the transaction target party, the other party of the target transaction can be a transaction initiator.

In step S308, if the transaction completion message of the target transaction and the notification message are acquired, it is determined that the target transaction is completed.

In step S310, a transaction status flag of the target transaction in the trusted execution environment is set by the in-transaction to transaction complete.

In step S312, the transaction information of the target transaction and the information of the transaction status flag of the target transaction are sent to enable the transaction clearing process to be performed on the target transaction based on the transaction information of the target transaction and the information of the transaction status flag of the target transaction and the preset clearing validity period corresponding to the target transaction.

In implementation, if the transaction status flag of the target transaction is transaction completion, the terminal device of the transaction initiator and/or the transaction target may send the transaction information of the target transaction and the information of the transaction status flag of the target transaction to determine whether the target transaction is within the clearing validity period based on the information of the transaction time and the like in the transaction information of the target transaction, if so, perform a transaction clearing process with a preset clearing validity period on the target transaction based on the transaction information of the target transaction and the information of the transaction status flag of the target transaction, and if not, refuse to perform the transaction clearing process on the target transaction.

It should be noted that, in practical applications, considering that a transaction target party usually provides a transaction object to a transaction initiator after a transaction is successful or the transaction is completed, and meanwhile, the transaction initiator may also use a resource card (such as a bank card or a shopping card) to perform settlement, the networking opportunity of the transaction initiator cannot be determined, and the transaction target party is generally a terminal device such as a mobile phone or a pos machine, and has a large number of opportunities to connect to a network, so that the transaction target party should perform a transaction clearing duty, that is, the transaction clearing process may be subject to the transaction information provided by the transaction target party, and the transaction information provided by the transaction initiator is used as an auxiliary verification, thereby completing the transaction clearing process of the target transaction.

In step S314, in the case of receiving the transmitted notification message that the transaction clearing process of the target transaction is completed, the transaction information of the target transaction and the transaction status flag of the target transaction stored in the trusted execution environment are cancelled.

The processing manner of step S314 may be various, and an optional processing manner is provided below, and may specifically include the following processing of step a2 and step a 4.

In step a2, in the case of receiving the notification message that the transaction clearing process of the sent target transaction is completed, it is determined whether the transaction information of the target transaction stored in the trusted execution environment meets a preset logout condition, where the logout condition is constructed based on the storage duration and/or the transaction type corresponding to the target transaction.

The storage duration may be a duration in which the transaction information of the target transaction is stored in the trusted execution environment, specifically, 15 days or 30 days, for example. The transaction type may include a variety of types, such as internal resource transfer of an organization (e.g., payment between different accounts of a certain financial application, etc.), resource allocation (e.g., payment between accounts of a bank and other financial institutions except the bank, etc.), resource transfer across organizations, etc., which may be specifically set according to actual situations. The logout condition may be, for example, if the storage duration of the transaction information of the target transaction in the trusted execution environment exceeds 30 days and the transaction type corresponding to the target transaction is intra-institution resource transfer, a logout procedure is executed, or if the storage duration of the transaction information of the target transaction in the trusted execution environment exceeds 15 days and the transaction type corresponding to the target transaction is cross-institution resource transfer, a logout procedure is executed, and the like, which may be specifically set according to an actual situation, and this is not limited in this description embodiment.

In step A4, if yes, transaction information of the target transaction and the transaction status flag of the target transaction stored in the trusted execution environment are revoked.

In practical applications, the transaction initiator and the transaction target may further assist each other to complete the transaction clearing process, which may specifically include the following process of step S316.

In step S316, if it is detected that the trusted execution environment of the terminal device of the other party of the target transaction includes transaction information of the first transaction whose transaction status is marked as transaction completion and for which the transaction clearing process is not requested to be performed, the transaction information of the first transaction is acquired from the terminal device of the other party of the target transaction, and is sent to cause the transaction clearing process to be performed on the first transaction based on the transaction information of the first transaction.

Wherein the first transaction may be any transaction.

In the implementation, when only one of the two parties of the target transaction is connected with the network, during the process of performing the target transaction, the party connected with the network can assist the party not connected with the network to perform the synchronization of the transaction so as to complete the transaction clearing, specifically, when the terminal device (connected network) of the transaction target party of the target transaction scans the payment two-dimensional code provided by the mobile phone (not connected with the network) of the transaction initiator, the terminal device of the transaction target party can detect whether the trusted execution environment of the mobile phone of the transaction initiator includes the transaction information of the transaction of which the transaction state is marked as transaction completion and the transaction information of the transaction of which the transaction clearing processing is not requested to be executed, and if the trusted execution environment of the mobile phone of the transaction initiator includes the transaction information of which the transaction state is marked as transaction completion and the transaction information of the first transaction of which the transaction clearing processing is not requested to be executed, the transaction information of the first transaction is acquired from the trusted execution environment of the mobile phone of the transaction initiator, and transmitting transaction information of the first transaction to which a transaction clearing process may be performed based on the transaction information of the first transaction. Similarly, when the mobile phone (connected to the network) of the transaction initiator of the target transaction scans the two-dimensional payment code provided by the terminal device (not connected to the network) of the transaction target, the mobile phone of the transaction initiator may detect whether the trusted execution environment of the terminal device of the transaction target includes transaction information of a transaction whose transaction state is marked as transaction completion and for which the transaction is not requested to execute the transaction clearing process, and if it is detected that the trusted execution environment of the terminal device of the transaction target includes transaction information of a first transaction whose transaction state is marked as transaction completion and for which the transaction clearing process is not requested to be executed, obtain the transaction information of the first transaction from the trusted execution environment of the terminal device of the transaction target, and send the transaction information of the first transaction to the mobile phone of the transaction initiator, which may execute the transaction clearing process for the first transaction based on the transaction information of the first transaction.

In addition, the corresponding recording rule of the transaction information is designed based on the transaction state mark, double spending (resource pre-transfer can be carried out if the transaction information exists) can be effectively prevented, asynchronous transaction information caused by network reasons is prevented, in addition, the transaction information synchronization rule based on the clearing validity period is set, arbitration of disputed transactions can be effectively carried out, in addition, the transaction information is synchronized based on the network of the terminal equipment of one party in the transaction, therefore, the synchronization time of the transaction information can be greatly increased, and uncontrollable transaction caused by overlong transaction recording offline time is prevented.

EXAMPLE III

As shown in fig. 4, an execution main body of the method may be a server, where the server may be a background server that provides access to a certain service (e.g., a service performing a transaction or a financial service) or a certain transaction object, specifically, the server may be a server of a payment service, or a server of a service related to financial or instant messaging, and the server may be the clearing server described in the second embodiment. A corresponding off-line transaction processing system may be as shown in fig. 2. The method may specifically comprise the steps of:

in step S402, transaction information of a target transaction and information of a transaction state flag of the target transaction sent by the terminal device are received, where the transaction information of the target transaction and the information of the transaction state flag of the target transaction are stored in a trusted execution environment of the terminal device, the target transaction is a transaction in an offline transaction scenario, the transaction state flag of the target transaction is generated and set as a transaction state flag in the transaction after the transaction information of the target transaction is stored in the trusted execution environment, and when the target transaction is completed, the transaction state flag of the target transaction in the trusted execution environment is set as transaction completion from the transaction.

In step S404, transaction clearing processing is performed on the target transaction based on the information of the transaction party in the target transaction to which the terminal device belongs, the transaction information of the target transaction, and the information of the transaction state flag of the target transaction, and the preset clearing validity period corresponding to the target transaction.

The embodiment of the present specification provides a processing method of an offline transaction, which receives transaction information of a target transaction and information of a transaction state flag of the target transaction sent by a terminal device, where the transaction information of the target transaction and the information of the transaction state flag of the target transaction are stored in a trusted execution environment of the terminal device, the target transaction is a transaction in an offline transaction scenario, the transaction state flag of the target transaction is generated and set as the transaction state flag in the transaction after the transaction information of the target transaction is stored in the trusted execution environment, and when the target transaction is completed, the transaction state flag of the target transaction in the trusted execution environment is set as a transaction completion from the transaction, and then, based on information of a transaction party in the target transaction to which the terminal device belongs, the transaction information of the target transaction and the information of the transaction state flag of the target transaction, and executing transaction clearing processing on the target transaction according to the preset clearing validity period corresponding to the target transaction, so that the offline transaction is cleared based on the clearing validity period and the transaction state mark, thereby effectively avoiding transaction disputes, reducing the investment loss and improving the transaction safety and transaction experience.

Example four

As shown in fig. 5, an execution main body of the method may be a server, where the server may be a background server that provides access to a certain service (e.g., a service performing a transaction or a financial service) or a certain transaction object, specifically, the server may be a server of a payment service, or a server of a service related to financial or instant messaging, and the server may be the clearing server described in the second embodiment. A corresponding off-line transaction processing system may be as shown in fig. 2. The method may specifically comprise the steps of:

in step S502, transaction information of a target transaction and information of a transaction state flag of the target transaction sent by the terminal device are received, where the transaction information of the target transaction and the information of the transaction state flag of the target transaction are stored in a trusted execution environment of the terminal device, the target transaction is a transaction in an offline transaction scenario, the transaction state flag of the target transaction is generated and set as a transaction state flag in the transaction after the transaction information of the target transaction is stored in the trusted execution environment, and when the target transaction is completed, the transaction state flag of the target transaction in the trusted execution environment is set as transaction completion from the transaction.

In practical applications, when the transaction status of the target transaction in the trusted execution environment is marked as in transaction, if the transaction initiator finds a repeat transaction or a transaction error, the transaction initiator may apply for transaction rollback, and at this time, the transaction initiator may initiate a transaction arbitration request, which may specifically include the following processing of steps S504 to S508.

In step S504, a transaction arbitration request of the target transaction sent by the terminal device is received, where the transaction arbitration request is sent when the transaction status of the target transaction in the trusted execution environment is marked as in-transaction.

In step S506, based on the transaction arbitration request, the related information of transaction clearing for the target transaction is obtained within the preset clearing validity period.

In implementation, after receiving a transaction arbitration request of a target transaction sent by a terminal device, a server may send a relevant notification message such as waiting for processing to the terminal device of a transaction initiator, and meanwhile, may determine whether the target transaction is within a preset clearing validity period based on transaction information of the target transaction, and if so, obtain relevant information for performing transaction clearing on the target transaction, specifically, transaction information of the target transaction, and the like, within the preset clearing validity period.

In step S508, if the relevant information for transaction clearing of the target transaction is not acquired within the preset clearing validity period, the transaction arbitration process corresponding to the transaction arbitration request is executed.

In implementation, if the relevant information for performing transaction clearing on the target transaction is not acquired within the preset clearing validity period, it indicates that the target transaction is an incomplete transaction, at this time, it may be determined that the transaction arbitration request submitted by the transaction initiator is valid, and the transaction arbitration process corresponding to the transaction arbitration request may be executed, for example, a transaction rollback may be performed on the target transaction, so as to perform processing such as refund on the transaction initiator.

In step S510, if the transaction party in the target transaction to which the terminal device belongs is the transaction initiator and the transaction status of the target transaction is marked as transaction completion, the related information for performing transaction clearing on the target transaction sent by the target party of the target transaction is received within the preset clearing validity period.

In step S512, if the related information for transaction clearing for the target transaction sent by the target party of the target transaction is received within the preset clearing validity period, a transaction clearing process is performed on the target transaction based on the transaction information for the target transaction and the received related information for transaction clearing for the target transaction sent by the target party.

In step S514, if the transaction party in the target transaction to which the terminal device belongs is the target party, the transaction status flag of the target transaction is transaction completion, and the transaction information of the target transaction and the information of the transaction status flag of the target transaction are received within the preset clearing validity period, the transaction clearing process is performed on the target transaction based on the transaction information of the target transaction.

In practical applications, the transaction initiator and the transaction target may further assist each other to complete the transaction clearing process, and specifically, the following processes of step S516 and step S518 may be included.

In step S516, transaction information of the first transaction sent by the terminal device is received, where the transaction information of the first transaction is transaction information that the terminal device detects that the trusted execution environment of the terminal device of the other party of the target transaction includes a transaction state that is marked as transaction completion and does not request execution of transaction clearing processing.

In step S518, a transaction clearing process is performed on the first transaction based on the transaction information of the first transaction.

EXAMPLE five

As shown in fig. 6A and fig. 6B, an execution main body of the method may be a blockchain system, and the blockchain system may be composed of a server and the like, where the server may be a background server for providing access to a certain service (such as a service for performing a transaction or a financial service) or a certain transaction object, and specifically, the server may be a server for a payment service, or a server for a service related to financial or instant messaging, and the like. The method may specifically comprise the steps of:

in step S602, rule information for executing transaction clearing processing on the target transaction is acquired, a corresponding first intelligent contract is generated based on the rule information for executing transaction clearing processing on the target transaction, and the first intelligent contract is deployed into the blockchain system.

Wherein the first intelligent contract may be a computer protocol intended to propagate, verify or execute contracts in an informational manner, the first intelligent contract allowing trusted interaction without third parties, the process of such interaction being traceable and irreversible, the first intelligent contract including agreements on which contract participants may execute rights and obligations agreed.

In implementation, in order to make traceability of the transaction clearing process performed on the target transaction better, a specified blockchain system may be created or added, so that the transaction clearing process may be performed on the target transaction based on the blockchain system, specifically, a corresponding application program may be installed in a blockchain node, an input box and/or a selection box and the like of rule information for performing the transaction clearing process on the target transaction may be set in the application program, and corresponding information may be set in the input box and/or the selection box. The blockchain system may then receive rule information to perform a transaction clearing process on the target transaction. The blockchain system may generate a corresponding first intelligent contract based on the rule information for executing the transaction clearing process on the target transaction, and may deploy the first intelligent contract into the blockchain system, so that the rule information for executing the transaction clearing process on the target transaction and the corresponding first intelligent contract are stored in the blockchain system, other users cannot tamper with the rule information for executing the transaction clearing process on the target transaction and the corresponding first intelligent contract, and the blockchain system executes the transaction clearing process on the target transaction through the first intelligent contract.

In step S604, transaction information of the target transaction and information of a transaction state flag of the target transaction sent by the terminal device are received, where the transaction information of the target transaction and the information of the transaction state flag of the target transaction are stored in a trusted execution environment of the terminal device, the target transaction is a transaction in an offline transaction scenario, the transaction state flag of the target transaction is generated and set as a transaction state flag in the transaction after the transaction information of the target transaction is stored in the trusted execution environment, and when the target transaction is completed, the transaction state flag of the target transaction in the trusted execution environment is set as transaction completion from the transaction.

In practical applications, when the transaction status of the target transaction in the trusted execution environment is marked as in-transaction, if the transaction initiator finds a duplicate transaction or a transaction error, the transaction initiator may apply for transaction rollback, and at this time, the transaction initiator may initiate a transaction arbitration request, which may specifically include the following processing of step B2 to step B6.

In step B2, a transaction arbitration request of the target transaction sent by the terminal device is received, the transaction arbitration request being sent when the transaction status of the target transaction in the trusted execution environment is marked as in-transaction.

In step B4, a third smart contract pre-deployed in the blockchain system is called, and based on the transaction arbitration request, information related to transaction clearing for the target transaction is obtained within a preset clearing validity period.

In implementation, the third intelligent contract may be provided with related rule information for acquiring, within a preset clearing validity period, related information for performing transaction clearing on the target transaction and related rule information for performing transaction arbitration processing corresponding to the transaction arbitration request, so that the corresponding processing may be implemented based on the rule information in the third intelligent contract, which may be referred to specifically for the above-mentioned related contents, and is not described herein again.

In step B6, if the relevant information for transaction clearing of the target transaction is not acquired within the preset clearing validity period, the transaction arbitration process corresponding to the transaction arbitration request is executed based on the third intelligent contract.

In step S606, a first intelligent contract is invoked, and transaction clearing processing is performed on the target transaction based on the information of the transaction party in the target transaction to which the terminal device belongs, the transaction information of the target transaction, the information of the transaction state flag of the target transaction, and the preset clearing validity period corresponding to the target transaction.

In implementation, the first intelligent contract may be provided with information of a transaction party in a target transaction, transaction information of the target transaction, information of a transaction state flag of the target transaction, and related rule information for executing transaction clearing processing on the target transaction based on a preset clearing validity period corresponding to the target transaction, so that the corresponding processing may be implemented based on the rule information in the first intelligent contract, which may be referred to as the related content specifically, and is not described herein again.

In practical applications, the specific processing of step S606 may be various, and two alternative processing manners are provided below, which may specifically include the following manner one and manner two.

The first method is as follows: the following step C2 and step C4 may be included.

In step C2, if the transaction party in the target transaction to which the terminal device belongs is the transaction initiator and the transaction status of the target transaction is marked as transaction completion, the related information of transaction clearing for the target transaction sent by the target party of the target transaction is received within the preset clearing validity period based on the first intelligent contract.

In step C4, if the information related to the transaction settlement for the target transaction sent by the target party of the target transaction is received within the preset settlement validity period, a transaction settlement process is performed on the target transaction based on the first intelligent contract, the transaction information of the target transaction and the received information related to the transaction settlement for the target transaction sent by the target party.

In implementation, the first intelligent contract may further include related information for performing transaction clearing on the target transaction, which is sent by the target party that receives the target transaction within a preset clearing validity period, and related rule information for performing transaction clearing processing on the target transaction based on the transaction information of the target transaction and the received related information for performing transaction clearing on the target transaction, which is sent by the target party, so that the corresponding processing may be implemented based on the rule information in the first intelligent contract, which may be referred to specifically for the above related contents, and details are not described herein again.

The second method comprises the following steps: and if the transaction party in the target transaction to which the terminal equipment belongs is the target party, the transaction state mark of the target transaction is transaction completion, and the transaction information of the target transaction and the information of the transaction state mark of the target transaction are received in the preset clearing validity period, executing transaction clearing processing on the target transaction based on the first intelligent contract and the transaction information of the target transaction.

In implementation, the first intelligent contract may further include related rule information for executing transaction clearing processing on the target transaction based on the transaction information of the target transaction, so that the corresponding processing may be implemented based on the rule information in the first intelligent contract, which may be referred to specifically for the above related contents, and is not described herein again.

In step D2, the transaction information of the first transaction sent by the terminal device is received, where the transaction information of the first transaction is the transaction information that the terminal device detects that the trusted execution environment of the terminal device of the other party of the target transaction includes the transaction state that is marked as transaction completion and does not request the blockchain system to execute the transaction clearing process.

In step D4, a second smart contract pre-deployed in the blockchain system is invoked, and a transaction clearing process is performed on the first transaction based on the transaction information of the first transaction.

In implementation, the second intelligent contract may be provided with relevant rule information for executing transaction clearing processing on the first transaction based on the transaction information of the first transaction, so that the corresponding processing may be implemented based on the rule information in the second intelligent contract, which may be referred to in detail for the above-mentioned relevant content, and is not described herein again.

The specific processing of step S606 may refer to the relevant contents in the above first and second embodiments, that is, various processing related to the above first and second embodiments may be implemented by the first smart contract.

The embodiment of the specification provides a processing method of off-line transaction, which includes the steps of obtaining rule information for executing transaction clearing processing on target transaction, generating a corresponding first intelligent contract based on the rule information for executing the transaction clearing processing on the target transaction, deploying the first intelligent contract into a blockchain system, calling the first intelligent contract when receiving transaction information of the target transaction and information of a transaction state mark of the target transaction sent by a terminal device, executing the transaction clearing processing on the target transaction based on information of a transaction party in the target transaction to which the terminal device belongs, the transaction information of the target transaction and the information of the transaction state mark of the target transaction and a preset clearing validity period corresponding to the target transaction, wherein the transaction information of the target transaction and the information of the transaction state mark of the target transaction are stored in a trusted execution environment of the terminal device, the target transaction is a transaction under an offline transaction scene, the transaction state flag of the target transaction is generated and set as a transaction state flag in the transaction after the transaction information of the target transaction is stored in the trusted execution environment, and the transaction state flag of the target transaction in the trusted execution environment is set to be completed from the transaction in the transaction under the condition that the target transaction is completed.
