For convenience of understanding, a specific flow of the embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of the information providing method based on the QR two-dimensional code in the embodiment of the present invention includes:

101. acquiring third-party information provided by a third-party service, and extracting all key information in the third-party information to form an information description file;

it is understood that the execution subject of the present invention may be an information providing apparatus based on a QR two-dimensional code, and may also be a terminal or a server, and may even be a software platform/system, which is not limited herein. The embodiment of the present invention is described by taking a server as an execution subject.

In this embodiment, the third-party information is specifically non-order information such as advertisement information, and the logistics company system acquires relevant information of a cooperative third party based on a cooperation agreement, and extracts the advertisement information from the relevant information, even the advertisement information related to the file content, to generate the information description file.

In practical application, after the logistics company system is authorized based on cooperation, information for cooperative popularization, namely advertisement information, such as information of merchants or platforms for buying vegetables, buying fruits, selling points and the like, is captured from a third-party system in a crawler mode, the information is preprocessed to form data meeting the QR two-dimensional code generation regulation, namely the data is subjected to processing such as deletion, redundancy removal or filling, key information extraction is performed on the data after the processing is finished to obtain key information in the third-party information, and an information description file is formed based on the key information.

The information description file is that when adding advertisement into video media or audio media file, it builds classified storage information of advertisement by adopting methods of classifying, searching and extracting information for all advertisements, then adopts manual identification or automatic identification or simultaneously uses the above two methods to identify image, sound and character parts in the said media file, and matches the identified result with the existing classified storage information of advertisement to make matching of successfully matched part to generate advertisement description file, said file records the position of extracting advertisement, playing time or playing in some frames and region information of advertisement.

102. Extracting information characteristics from all key information by using a preset array encryption algorithm to generate a corresponding encrypted array;

in this embodiment, the array encryption algorithm refers to an encryption method that combines encrypted data and unencrypted data, that is, after extracting a part of data from data to be encrypted and encrypting one by one, mixing the encrypted part of data with the unencrypted part of data, so as to obtain final ciphertext data.

In practical application, if the information description file is a description file of an advertisement, when extracting key information, information features in the key information can be specifically extracted through a knowledge graph model related to the advertisement, optionally, feature extraction is performed on each key information, then ranking is performed based on the extracted features to obtain a feature sequence, and then a plurality of features are randomly selected from the feature sequence to form an encrypted array.

103. Correspondingly encrypting the information description file based on the encryption number group to obtain a ciphertext, and converting the ciphertext into a first QR two-dimensional code;

in this embodiment, the encryption may be understood as mixing information in an encrypted array with information in an information description file to obtain a mixture of encrypted data and unencrypted data, specifically, taking original data of the encrypted data in the encrypted array as an index, comparing data consistent in the information description file, then replacing the data with the encrypted data to obtain a data mixture, inputting the data mixture into a QR two-dimensional code generating program to perform two-dimensional code conversion, so as to obtain a first QR two-dimensional code corresponding to the information description file.

104. When an order task is received, extracting recipient information and order information in a distribution order corresponding to the order task, and determining a key corresponding to a distribution station corresponding to the recipient information;

in the step, the logistics company system monitors whether a new order is generated on the current system, if so, the corresponding distribution order is obtained, relevant information of a receiver in the distribution order, including the receiver information and the receiver address information, is extracted, a distribution center or a distribution station corresponding to the receiver in a distribution network is inquired based on the receiver address information, a corresponding key is inquired according to the distribution station, and the key is an encryption and decryption key when the order information is converted into a two-dimensional code.

In this embodiment, the key is specifically obtained by:

after the logistics company system receives the order task, planning a distribution line based on a mail sending address and a mail receiving address in the order task to obtain the distribution line;

extracting a distribution center, a middle station and an end station in a distribution line, and distributing corresponding keys based on the information of the stations; when the key is distributed, the end point distribution station needs to generate a unique key in combination with the recipient information, and preferably, the key can be generated in the same way as the encryption array.

105. Encrypting the first QR two-dimensional code by using a secret key to obtain a second QR two-dimensional code;

in this step, specifically, the generating of the second QR two-dimensional code is:

the first QR two-dimensional code is subjected to informationization extraction, and the extracted information block is divided into public information and private information according to privacy grades in combination with order information, wherein the private information can basically specify recipient information and recipient address information in the order information, the public information is directly third-party information, and the public information refers to a state of being kept encrypted by an encryption array and does not need to be secondarily encrypted by key information;

encrypting the private information by using a secret key by adopting an encryption algorithm, carrying out bit stream transformation on the obtained encrypted private information and public information to respectively obtain a bit stream string of the private information and a bit stream string of the public information, and sequentially connecting the bit stream string of the public information, a terminator, a private information indicator, the bit stream string of the private information and the terminator into a final bit stream string;

and calling a QR code generation algorithm, and encoding the final bit stream string to generate a second QR two-dimensional code.

106. Adding the order information into the second QR two-dimensional code to generate an information providing code;

in the step, the order number in the order information is added into the second QR two-dimensional code, and a combined image is formed with the second QR two-dimensional code, that is, a display image of the two-dimensional code plus the order number.

Of course, in practical application, the waybill number and the second QR two-dimensional code may be updated again according to the mode of generating the second QR two-dimensional code.

107. And when a sign-in instruction is received, scanning the information providing code through a terminal of a receiver, decrypting the information providing code according to the encryption array and the secret key to obtain corresponding third-party service information, and displaying the third-party service information on the terminal.

In the step, after the delivery station staff delivers the express item, the recipient scans the information providing code on the express item by using the terminal device (such as a mobile phone), and the terminal device decrypts the information providing code according to the encrypted array corresponding to the logistics company and the key corresponding to the delivery station to obtain the corresponding third-party service information, namely non-order information such as advertisement information, and then the terminal device notifies the recipient of the non-order information.

In practical application, the information providing code is actually a two-layer encrypted combined two-dimensional code, the first layer is a QR two-dimensional code of third-party information, the second layer is a two-dimensional code of order information, and the two-dimensional code of order information may be a QR two-dimensional code or a conventional two-dimensional code, which is specifically selected according to requirements.

After two layers of two-dimensional codes are generated, the two-dimensional codes are combined through an image combination technology, and the combination can be combined in an enclosing mode, namely, a first QR two-dimensional code is used as an insertion image to be combined with order information to generate a combined two-dimensional code, the middle part of the combined two-dimensional code is the first QR two-dimensional code, and the edge part of the combined two-dimensional code is the two-dimensional code of the order information.

The other mode is fusion combination, namely, after the first QR two-dimensional code is marked, a part of code segments carrying information in the first QR two-dimensional code is extracted, a two-dimensional code is generated based on order information, and the extracted code segments are uniformly distributed in the two-dimensional code to obtain a new QR two-dimensional code.

After the terminal scans the two-dimensional code, the scanned two-dimensional code is firstly dissected to obtain two-dimensional code images, the two-dimensional code images are respectively identified, and the two-dimensional code images are respectively decrypted by adopting the encryption array and the secret key to obtain corresponding decryption data. And displaying signing operation on order information, pushing information on third-party service information, displaying the information on a display screen of the terminal, and pushing according to behavior habits of a user.
