In order to clearly describe the subway ticket secondary selling method, the concrete steps are described by combining each execution main body, and the concrete steps are as follows:

before the subway ticket secondary selling method is executed, a third party company needs to be registered, a company needing to purchase a two-dimensional code subway ticket sold by a subway party registers in the subway party and uploads the company to a second database module of a cloud server based on the subway party sold for the second time, a digital certificate of the third party company is generated, and the registration and authentication of the third party company are completed.

Before a user purchases a two-dimensional code metro ticket through a user terminal APP developed by a third party company which completes registration and authentication, user registration is needed, the user registers a user name, an identity card number, a mobile phone number and a payment mode in a user management module in the user terminal APP, the user communicates with a third party background server to generate a digital certificate of the user, registration is completed, and when information needs to be changed subsequently, the user also operates in the user management module.

Referring to fig. 5, a process of taking a subway by a user using a user terminal APP:

(1) please code: the user firstly establishes communication with a third-party background server through a two-dimension code management module of the user terminal APP, and the user terminal APP carries out digital signature on user information by using a user private key and sends the user information to the third-party background server to apply for the two-dimension code metro ticket. And the third-party background server inquires the digital certificate of the user, verifies the validity of the signature of the user by using the digital certificate of the user, and returns error prompt information to the user terminal APP if the verification fails. If the verification is passed, the third-party background server sends an information data packet (namely a data packet acquisition request) containing third-party company information and user information and signed by using a private key of the third-party company to the cloud server through the interface management module, wherein the data packet acquisition request is a request carrying the information data packet containing the third-party company information and the user information and signed by using the private key of the third-party company, and the code sending module of the cloud server judges the validity of the data packet by inquiring a digital certificate of the third-party company and verifying the validity of the signature of the third-party company by using the digital certificate. And if the verification fails, returning error prompt information to the third-party company background server. If the verification is passed, firstly, a cloud server key module generates a pair of keys (the keys comprise a private key and a public key), the generated private key is used for digitally signing a two-dimensional subway ticket data packet containing information such as third-party company information, user information, a timestamp and the like, the public key is transmitted to a key management module of a two-dimensional code gate machine through wireless communication, then the two-dimensional subway ticket data packet is firstly transmitted to a third-party background server and then transmitted to a user terminal APP by the third-party background server, the user terminal APP generates a two-dimensional subway ticket according to the two-dimensional subway ticket data packet transmitted by the cloud server, as the information of the two-dimensional subway ticket comprises two-dimensional subway ticket generation time and effective time (the effective time can be set according to actual conditions, if the effective time is set to be 30s, a code requesting process needs to be carried out again every 30s, a new two-dimensional subway ticket is obtained from the cloud server through the third-party background server, otherwise, the two-dimension code metro ticket cannot be used.

(2) Entering and exiting the station: the user is when the two-dimensional code scanning module of two-dimensional code gate machine with two-dimensional code subway ticket alignment when entering the station, two-dimensional code subway ticket on the user terminal APP is gathered to the two-dimensional code gate machine, this two-dimensional code subway ticket is by the encrypted two-dimensional code subway ticket of cloud ware signature, two-dimensional code subway ticket is decoded to the two-dimensional code gate machine, obtain two-dimensional code information, this two-dimensional code information includes the data package that contains information such as third party company information, user information, two-dimensional code generation time, two-dimensional code effective time that the private key signature was used to the cloud ware. The gate verification module verifies the digital signature of the two-dimensional code metro ticket through a public key issued by the cloud server, and judges the validity of the two-dimensional code metro ticket. And if the judgment result is illegal, displaying error information on a gate display screen. If the two-dimensional code metro ticket is legal, the cloud server transaction verification module is communicated with the cloud server transaction verification module, the validity of the two-dimensional code metro ticket is verified on line, and verification contents comprise: the method comprises the steps of checking transaction weight, judging whether the travel time is overtime or not, logically judging whether the travel station enters or exits or not, judging whether unprocessed ticketing is abnormal or not, controlling a door of a two-dimensional code gate to be opened after verification is passed, and transmitting the identified two-dimensional code information to a second database module of a cloud server. If the verification fails, the abnormal information is transmitted to a third-party background server in a wireless transmission mode through a transaction verification module of the cloud server, the third-party background server wirelessly transmits the abnormal information to the user terminal APP through an interface management module and displays the abnormal information in a login supplementing module of the user terminal APP, and a user can complete transaction login supplementing operation in the user terminal APP according to the abnormal information.

(3) Transaction processing: the travel matching module of the cloud server generates user travel information according to the station passing in and out and the time in the transaction records uploaded by the two-dimensional code gate machine, the transaction fee deduction module calculates the fee according to the travel information, the cloud server requests money from the third-party background server, then the third-party background server requests money from the user terminal APP, the fee deduction information is wirelessly transmitted to the user terminal APP, the user completes payment operation, meanwhile, the transaction information is stored in the second database module of the cloud server and the first database module of the third-party background server, and the subsequent subway party carries out account settlement on different third-party companies.

Wherein, the processing process is further described by the angle of the two-dimensional code gate:

(1) scanning the two-dimensional code subway ticket: the two-dimensional code gate machine collects a two-dimensional code subway ticket displayed on a user terminal APP, and the two-dimensional code subway ticket is signed and encrypted by a cloud server.

(2) Decoding the two-dimension code metro ticket: and decoding the two-dimension code metro ticket to obtain a data packet which is signed by the cloud server by using a private key and contains information of third party company, user information, two-dimension code generation time, two-dimension code effective time and the like.

(3) And (3) decrypting the digital signature: the gate machine verification module of the two-dimensional code gate machine analyzes the digital signature according to the public key generated and transmitted by the cloud server, and the two-dimensional code metro ticket can be judged to be generated and issued by the cloud server as long as the gate machine verification module can correctly verify the digital signature, so that the content is not tampered, and the two-dimensional code metro ticket is real and credible. And the gate machine verification module transmits the analyzed two-dimension code information and the station information to which the two-dimension code gate machine belongs to the cloud server in a wireless communication mode.

(4) And (3) two-dimensional code verification: the cloud server verifies the validity and effectiveness of the two-dimensional code subway ticket, judges the logic of entering and leaving the station of the two-dimensional code subway ticket, and respectively verifies whether the two-dimensional code subway ticket enters the station or leaves the station. The inbound verification comprises whether unprocessed unilateral transaction or abnormal information exists; the outbound verification comprises the conditions of whether unprocessed unilateral transaction or abnormal information exists, whether the travel time is overtime and whether the two-dimensional code subway ticket is multiplexed. And the cloud server stores the information after transaction verification and transmits a verification result to the two-dimensional code gate.

(5) And (4) opening and closing a gate: if the verification is passed, the two-dimensional code gate machine controls the opening of the leaf door according to the verification result transmitted by the cloud server. If the verification fails, the cloud server transmits the abnormal information to the user terminal APP through the third-party background server, and the user needs to complete the login operation on the user terminal APP, so that the user can continue to use the two-dimensional code subway ticket to complete the station entering and exiting operation.
