[0044] A non-fungible token (NFT) is a unique data representation recorded on a blockchain that cannot be copied, replaced, or divided, and is used to verify the authenticity or rights of a specific digital asset. This type of digital crypto asset is unique, scarce, and non-replicable. NFT use cases range from digital art, domain names, games, collectibles, and more. NFTs are minted on a blockchain (such as Ethereum) and can be used to verify asset ownership. They have the following characteristics: (1) Decentralized ownership: There is no need for a central authority to act as a trusted custodian, and asset ownership can be easily transferred on the blockchain, saving time and cost; (2) Enhanced liquidity: Tokenization will enable us to release liquidity from illiquid assets that are difficult to physically divide; (3) Fractional ownership: Each token represents a small portion of the overall value of the asset, which reduces the barrier to investment and allows anyone to own a small piece of the asset; (4) 24 / 7 accessibility: Assets can be bought and sold at any time through instant smart contract technology; (5) Fast ownership transfer: Ownership can be transferred instantly.

[0045] Terminal devices may include, but are not limited to, mobile phones, smart TVs, smart speakers, wearable devices, tablet computers, desktop computers, all-in-one computers, handheld computers, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), laptop computers, mobile computers, augmented reality (AR) devices, virtual reality (VR) devices, artificial intelligence (AI) devices, vehicle-mounted devices, and any other terminal devices or portable terminal devices.

[0046] Please refer to Figure 1, which is a schematic diagram of the functional modules of the identity recognition system provided in an embodiment of the present application. The identity recognition system includes multiple modules, each of which is used to implement different functions. In this embodiment, the identity recognition system includes: a client 1, a QR code identity information center 2, and a publisher management center 3.

[0047] Client 1 is an App application or web page interface provided by the publisher or user, which makes it easy for the user or publisher to use the backend service.

[0048] The QR code identity information center 2 runs on the blockchain and is built through a consortium chain or a public chain to achieve full life cycle management of QR code identity information, including addition, deletion, modification, query, and transfer of QR codes between publishers.

[0049] The Publisher Management Center 3 provides QR code publisher registration, login, and publisher information management capabilities. QR code publishers are divided into corporate publishers and individual publishers. Corporate publishers need to pass corporate real-name authentication, while individual publishers need to pass personal real-name authentication.

[0050] In some embodiments, the publisher needs to register an account on client 1. Specifically, client 1 responds to the publisher's registration request by sending the registration request to publisher management center 3; publisher management center 3 receives the registration request, processes the registration request, and sends a registration success message to client 1 after the processing is complete; client 1 receives the real-name authentication information and sends the real-name authentication information to publisher management center 3; publisher management center 3 performs real-name authentication on the publisher based on the real-name authentication information, and after the real-name authentication is successful, sends an authentication pass message to client 1, indicating that the publisher has successfully registered an account on client 1.

[0051] For ease of understanding, the following takes an enterprise publisher as an example, and describes in detail the registration process of the enterprise publisher on the client in this embodiment with reference to FIG2 :

[0052] Please refer to FIG. 2 , which is a schematic diagram of a process of registering an enterprise publisher on the client 1 according to this embodiment.

[0053] Steps (1.1) to (1.4) are the account registration process for corporate publishers. The specific process is as follows:

[0054] Step (1.1) The enterprise publisher initiates user registration on Client 1 through the terminal device. Taking Client 1 as Application A on the terminal device as an example, the enterprise publisher logs in to Application A, enters the account and password to be registered in Application A, and then clicks the "Register" button in Application A to complete the registration operation.

[0055] Step (1.2) Client 1 sends a registration request to the publisher management center 3. That is, after the corporate publisher enters the account and password to be registered on Client 1 and clicks the "Register" button, Client 1 sends the account and password to be registered to the publisher management center 3.

[0056] In step (1.3), publisher management center 3 sends a registration success message to client 1. Specifically, publisher management center 3 processes the registered account and password, checking for compliance with password specifications and duplicate accounts, and then sends a registration success message to client 1. It's worth noting that during account processing, publisher management center 3 also generates a unique key that matches the publisher's account.

[0057] Specifically, assuming that the account processed by the publisher management center 3 is AABBCC, during the processing of AABBCC, a private key matching AABBCC will be generated based on the private key generation algorithm of the blockchain. This private key is the aforementioned specific secret key.

[0058] Step (1.4) Client 1 displays the registration information to the corporate publisher. That is, after receiving the registration success information sent by the publisher management center 3, Client 1 displays the registration information on the terminal device for the corporate publisher to view. The registration information includes but is not limited to the registration time, registration location, registered account number and password, etc.

[0059] Steps (2.1) to (2.7) are the real-name authentication process after the enterprise publisher account is successfully registered. The specific process is as follows:

[0060] Step (2.1) The enterprise publisher initiates enterprise real-name authentication on Client 1 through a terminal device. That is, after the account is successfully registered, the enterprise publisher fills in the real-name authentication information on Client 1 and clicks Submit. The real-name authentication information includes but is not limited to the enterprise's business license, tax registration certificate, organization code certificate, etc.

[0061] Step (2.2): The client 1 sends an enterprise authentication request to the publisher management center 3. That is, the client 1 sends the aforementioned real-name authentication information to the publisher management center 3.

[0062] Step (2.3) The publisher management center 3 forwards the enterprise authentication request to the enterprise identity verification agency. That is, the publisher management center 3 initiates an enterprise real-name authentication request to the identity verification agency that verifies the enterprise identity to verify the authenticity of the real-name authentication information provided by the enterprise publisher.

[0063] Step (2.4) The enterprise identity verification agency sends a verification success message to the publisher management center 3. That is, the system of the enterprise identity verification agency automatically verifies the authenticity of the real-name authentication information, and sends a verification success message to the publisher management center 3 when the real-name authentication information is verified to be authentic.

[0064] Step (2.5) The enterprise identity verification agency manually reviews the real-name authentication information. This means the enterprise identity verification agency can also manually verify the authenticity of the real-name authentication information. This step is optional.

[0065] Step (2.6) The publisher management center 3 sends the authentication pass information to the client 1. That is, the publisher management center 3 sends the authentication pass information of the real-name authentication information to the client 1.

[0066] In step (2.7), client 1 displays the authentication information to the enterprise publisher. That is, after receiving the authentication pass information, client 1 displays the real-name authentication information of the enterprise publisher on the terminal device for the enterprise publisher to view.

[0067] For ease of understanding, the following takes an individual publisher as an example, and describes in detail the registration process of an individual publisher on the client in this embodiment in conjunction with FIG3 :

[0068] Please refer to FIG3 , which is a schematic diagram of a process of a personal publisher registering on the client 1 according to this embodiment.

[0069] Steps (3.1) to (3.4) are the account registration process for individual publishers. The specific process is as follows:

[0070] Step (3.1) The individual publisher initiates a registration operation on Client 1 through a terminal device. Taking Client 1 as Application B on the terminal device as an example, the individual publisher logs in to Application B, enters the account and password to be registered in Application B, and then clicks the "Register" button on Application B to complete the registration operation.

[0071] Step (3.2) Client 1 sends a registration request to the publisher management center 3. That is, after the individual publisher enters the account and password to be registered and clicks the "Register" button, Client 1 sends the account and password to be registered to the publisher management center 3.

[0072] In step (3.3), the publisher management center 3 sends a registration success message to the client 1. Specifically, the publisher management center 3 processes the registered account and password, checking for compliance with the password specifications and for duplicate accounts. After processing, the center sends a registration success message to the client 1. It's worth noting that after the publisher management center 3 completes the processing, it also generates a unique key that matches the individual publisher's account.

[0073] Step (3.4) Client 1 displays the registration information to the individual publisher. That is, after receiving the registration success message, Client 1 displays the registration information on the terminal device for the individual publisher to view. The registration information includes but is not limited to the registration time, registration location, registered account and password, etc.

[0074] Steps (4.1) to (4.7) are the real-name authentication process after the individual publisher account is successfully registered. The specific process is as follows:

[0075] Step (4.1) The individual publisher initiates personal real-name authentication on Client 1 through the terminal device. That is, after the individual publisher's account registration is successful, the individual publisher fills in the real-name authentication information on Client 1 and clicks Submit. The real-name authentication information includes but is not limited to the individual publisher's ID card information.

[0076] Step (4.2): Client 1 sends a real-name authentication request to publisher management center 3. That is, client 1 sends real-name authentication information to publisher management center 3.

[0077] Step (4.3) The publisher management center 3 forwards the real-name authentication request to the personal identity verification agency. That is, the publisher management center 3 initiates a personal real-name authentication request to the identity verification agency that verifies the individual to verify the authenticity of the real-name authentication information provided by the individual publisher.

[0078] Step (4.4) The personal identity verification agency sends a verification success message to the publisher management center 3. That is, the personal identity verification agency's system automatically verifies the authenticity of the real-name authentication information, and sends a verification success message to the publisher management center 3 when the real-name authentication information is verified to be authentic.

[0079] Step (4.5) The personal identity verification agency manually reviews the real-name authentication information. That is, the personal identity verification agency can also manually verify the authenticity of the real-name authentication information. This step is optional.

[0080] Step (4.6) The publisher management center 3 sends the authentication pass information to the client 1. That is, the publisher management center 3 sends the real-name authentication information authentication pass information to the client 1.

[0081] Step (4.7) Client 1 displays the real-name information to the individual publisher. That is, after receiving the authentication pass information, Client 1 displays the real-name authentication information of the individual publisher on the terminal device for the individual publisher to view.

[0082] In some embodiments, after a corporate or individual publisher registers an account on client 1, the publisher continues to apply for a QR code on client 1. Specifically, QR code identity information center 2 receives the publisher's real-name authentication information and the original QR code information that the publisher needs to display, and generates an NFT value based on the real-name authentication information and the original QR code information. QR code identity information center 2 then generates target QR code information based on the NFT value and the address information of QR code identity information center 2, and sends the target QR code information to client 1. Client 1 generates a target QR code based on the target QR code information.

[0083] For ease of understanding, the following specifically describes how the publisher obtains the target QR code in this embodiment with reference to FIG4 :

[0084] Please refer to Figure 4, which is a flowchart of the QR code generation method provided in an embodiment of the present application.

[0085] From step (5.1) to step (5.3), publisher M logs in to client 1 based on the registered account.

[0086] In step (5.4), the individual or corporate publisher fills in the QR code information on Client 1. That is, after successfully logging in to Client 1, Publisher M enters the QR code publishing page of Client 1, where Publisher M fills in the original QR code information to be published. Taking the use of QR codes for product anti-counterfeiting as an example, in order to achieve product anti-counterfeiting, Publisher M publishes the product's unique serial number, coded as ABCD123456789, as the original QR code information. It is understandable that the QR code publishing page has a QR code information filling box, in which Publisher M fills in the content (product serial number: ABCD123456789, manufacturer: XXX) and submits it.

[0087] Step (5.5) Client 1 sends a QR code publishing request to the publisher management center 3. That is, Client 1 submits the user's QR code publishing request to the publisher management center, and the QR code publishing request carries the above-mentioned original QR code information.

[0088] Step (5.6) The publisher management center 3 fills in the publisher information. That is, after receiving the QR code publishing request submitted by the client 1, the publisher management center 3 associates the real-name authentication information and specific key information corresponding to the publisher M and adds it to the QR code publishing request.

[0089] Step (5.7): The publisher management center 3 sends a QR code publishing request to the QR code identity information center 2. That is, the publisher management center 3 forwards the supplemented QR code publishing request to the QR code identity information center 2.

[0090] In step (5.8), the QR code identity information center 2 calculates and stores the QR code. Specifically, the QR code identity information center 2 generates an NFT value based on the specific key information, the real-name authentication information, and the original QR code information, and generates the target QR code information based on the NFT value and the domain name address of the QR code identity information center 2.

[0091] Specifically, after receiving the supplemented QR code publishing request, the QR code identity information center will splice together the original QR code information submitted by publisher M (product serial number: ABCD123456789, manufacturer: XXX) and the real-name authentication information corresponding to publisher M, and then use the HMAC-Sha256 one-way hash algorithm to generate the NFT value through the specific secret key corresponding to the account registered by publisher M:

[0092] 66D0020FA79C04A3FE3EA9C5AB1672B8. The following target QR code information is generated based on the QR code identity center domain address and NFT splicing:

[0093] https: / / QrCodeId.test.com / idquery.action?NFT=66D0020FA79C04A3FE3EA9C5AB1672B8.

[0094] In addition, the QR Code Identity Information Center 2 will also store the real-name authentication information, the original QR code information, and the time the QR code was issued on the blockchain in the form of a smart contract. It is understood that NFT values ​​are unique, and each NFT value corresponds to a specific real-name authentication information, original QR code information, and the time the QR code was issued.

[0095] In step (5.9), the QR code identity information center 2 returns the new QR code information and NFT to the publisher management center 3. That is, the QR code identity information center 2 sends the target QR code information to the publisher management center 3. It is understood that the NFT value can also be returned to the publisher management center 3 at the same time.

[0096] In step (5.10), the publisher management center 3 returns the new QR code information and NFT to the client 1. That is, the publisher management center 3 sends the target QR code information to the client 1. It is understandable that if the QR code identity information center 2 returns the NFT value to the publisher management center 3 in the above step, the publisher management center 3 will also send the NFT value to the client 1.

[0097] In step (5.11), client 1 displays the new QR code, pattern, or NFT to the individual or corporate publisher. Specifically, client 1 has multiple ways to generate the target QR code. For example, client 1 can integrate a general QR code generation tool to generate the target QR code; client 1 can also directly use the QR code generation tool to generate the target QR code based on the target QR code information. Client 1 displays the generated target QR code to the individual or corporate publisher. More specifically, target QR code generation method 1: Generate the original QR code from the original QR code information, and then splice the NFT behind the original QR code to obtain the target QR code. Target QR code generation method 2: Directly generate the target QR code using the QR code authentication center address + NFT method.

[0098] In some embodiments, when publisher M fills in the original QR code information in step (5.4), publisher M also fills in the validity period of the QR code. The validity period can be valid for 3 years, 5 years, or until March 2025. Short-term validity or long-term validity can also be selected directly. This embodiment does not specifically limit the type of validity period. By setting the validity period, the user can be informed whether the current QR code is within the validity period when the QR code identity is displayed, and the expiration time of the QR code can be displayed to the user.

[0099] It is understandable that, after the publisher management center 3 sends the target QR code information to the client 1 in step (5.10), the client 1 may send a validity period filling request to the publisher, so that the publisher M can fill in the validity period.

[0100] In some embodiments, after publisher M receives the target QR code sent by client 1, publisher M can also manage the status of the published QR code on client 1, such as setting the published QR code that is still valid to invalid, extending the validity period of the published QR code, etc.

[0101] In some embodiments, after publisher M generates a target QR code, the target QR code is set on the product to prevent counterfeiting of the product. Specifically, client 1 responds to the user's recognition operation of the target QR code and sends an NFT query request to the QR code identity information center 2 based on the address information. The NFT query request carries the NFT value. The QR code identity information center 2 responds to the NFT query request sent by client 1 to query whether the NFT value matches the real-name authentication information and the original QR code information; and if the NFT value matches the real-name authentication information and the original QR code information, the real-name authentication information and the original QR code information are sent to client 1; client 1 displays the real-name authentication information and the original QR code information to the user.

[0102] For ease of understanding, the following describes in detail how identity recognition is performed based on the target QR code in this embodiment with reference to FIG. 5 to FIG. 7 :

[0103] Please refer to FIG5 , which is a flowchart of the QR code verification method provided in this embodiment.

[0104] In step (6.1), the user triggers a scan through the client 1. For example, the user uses application C on the terminal device to initiate the scan. Application C can be a scanning tool such as WeChat or Alipay, or a scanning tool client provided by the QR code identity information center 2.

[0105] Step (6.2) Client 1 parses the QR code information and NFT. For example, application C parses the QR code pattern to obtain the following QR code information:

[0106] https: / / QrCodeId.test.com / idquery.action?NFT=66D0020FA79C04A3FE3EA9C5AB1672B8

[0107] In step (6.3), client 1 sends an NFT query request to the QR code identity information center 2. That is, application C identifies the URL address of the QR code identity information center 2 by parsing the QR code information, and initiates an NFT query request to the QR code identity information center 2 based on the URL address.

[0108] In step (6.4), the QR Code Identity Information Center 2 queries the original QR code information, key, and publisher information stored in the blockchain based on the NFT, and verifies the consistency between the original product QR code information, publisher information, and the NFT. That is, after receiving the NFT query request, the QR Code Identity Information Center 2 queries the corresponding QR code identity information (i.e., the aforementioned real-name authentication information) and the original QR code information based on the NFT value carried in the URL address, and verifies the consistency between the NFT and the blockchain storage information using the specific secret key corresponding to the publisher account.

[0109] Step (6.5) The QR code identity information center 2 returns the QR code identity information page and the original product QR code information to the client 1. That is, after the QR code identity information center 2 passes the verification, it returns the QR code identity information and the original QR code information to the application C through the HTTPS channel.

[0110] From step (6.6) to step (6.9), application C returns the QR code identity information page to the terminal device. After the user confirms the QR code identity information, clicking Continue will further load the original QR code information, and the terminal device will display the product QR code information.

[0111] Please refer to Figure 6, which shows an application scenario where QR code verification is successful in this embodiment. After a user initiates a scan using Application C on a terminal device, the display interface of the user terminal device first displays the QR code identity information to the user. The QR code identity information includes but is not limited to the aforementioned real-name authentication information, QR code release time, QR code description, etc. After the user clicks the "Continue" button on the display interface, the display interface then displays the product's anti-counterfeiting information, i.e., the original QR code information.

[0112] Please refer to Figure 7, which shows an application scenario in which the QR code verification fails in this embodiment. After the user initiates a scan using application C on the terminal device, the terminal device's display interface displays a message indicating that the current QR code may be illegal and caution is advised because the QR code identity information center 2 fails to retrieve the corresponding real-name authentication information, original QR code information, and QR code issuance time based on the NFT value carried by the QR code, or because the NFT value does not match the information stored by the QR code identity information center 2.

[0113] Compared with the related art, the embodiments of the present application have at least the following advantages: the target QR code information includes the NFT value and the address information of the QR code identity information center, so that the target QR code generated according to the target QR code information carries less information, which improves the scanning speed, and the NFT value and address information have no actual meaning and are not easy to be identified and forged, thereby improving the anti-counterfeiting effect; in addition, since the NFT value is generated according to the real-name authentication information of the publisher and the original QR code information that the publisher needs to display, and the NFT value is unique, the authenticity of the QR code can be accurately judged by querying whether the identified NFT value matches the real-name authentication information and the original QR code information, further improving the anti-counterfeiting effect of the QR code.

[0114] Please refer to Figure 8, which is a flow chart of the identity authentication method provided in an embodiment of the present application. This embodiment is applied to the client 1 of the aforementioned embodiment, and the specific process is shown in Figure 8, including the following steps:

[0115] Step 101: The client receives target QR code information, which includes the NFT value and the address information of the QR code identity information center.

[0116] Specifically, the NFT value is generated based on the publisher's real-name authentication information and the original QR code information that the publisher needs to display, and the QR code information identity center is used to store the real-name authentication information and the original QR code information.

[0117] In some embodiments, before the client receives the target QR code information, the user needs to register an account on the client first. Specifically, the client responds to the registration request of the publisher and sends the registration request to the publisher management center. The publisher management center is used to process the registration request; after receiving the registration success information sent by the publisher management center, it receives the real-name authentication information sent by the publisher and sends the real-name authentication information to the publisher management center. The publisher management center is also used to verify the real-name authentication information; when the client receives the authentication pass information sent by the publisher management center, it indicates that the user's real-name authentication is successful. At this time, the user can log in to the client and enter the original QR code information. The client sends the original QR code information to the publisher management center, so that the publisher management center sends the original QR code information and the real-name authentication information to the QR code identity information center. The QR code identity information center generates the target QR code information based on the original QR code information and the real-name authentication information, and sends the target QR code information to the client.

[0118] Step 102: The client generates a target QR code according to the target QR code information.

[0119] In some embodiments, the client has multiple ways to generate the target QR code. The client can generate the target QR code by integrating a universal QR code generation tool; or it can directly use the QR code generation tool to generate the target QR code based on the target QR code information.

[0120] Step 103: In response to the user's recognition operation of the target QR code, an NFT query request is sent to the QR code identity information center according to the address information, and the NFT query request carries the NFT value.

[0121] In some embodiments, before sending an NFT query request to the QR code identity information center based on the address information, it also includes: parsing the target QR code to obtain the target QR code information; identifying the target QR code information to obtain the address information and the NFT value.

[0122] Specifically, the user initiates a scan through the terminal device and scans the target QR code. The client parses the target QR code information based on the QR code pattern, and then recognizes the target QR code information to obtain the address information and NFT value.

[0123] Step 104: When the NFT value is found to match the real-name authentication information and the original QR code information in the QR code identity information center, the real-name authentication information and the original QR code information are displayed to the user.

[0124] In one embodiment, the real-name authentication information and the original QR code information are displayed to the user in the following manner: a first display page is sent to the user's terminal device, and the first display page is used to display the real-name authentication information; in response to the user's operation on the first display page, the first display page is jumped to a second display page, and the second display page is used to display the original QR code information.

[0125] Compared with the related art, the embodiments of the present application have at least the following advantages: the target QR code information includes the NFT value and the address information of the QR code identity information center, so that the target QR code generated according to the target QR code information carries less information, which improves the scanning speed, and the NFT value and address information have no actual meaning and are not easy to be identified and forged, thereby improving the anti-counterfeiting effect; in addition, since the NFT value is generated according to the real-name authentication information of the publisher and the original QR code information that the publisher needs to display, and the NFT value is unique, the authenticity of the QR code can be accurately judged by querying whether the identified NFT value matches the real-name authentication information and the original QR code information, further improving the anti-counterfeiting effect of the QR code.

[0126] Please refer to FIG9 , which is a flowchart of a QR code verification method provided in an embodiment of the present application. This embodiment is applied to the QR code identity information center 2 of the aforementioned embodiment. The specific process is shown in FIG9 , including the following steps:

[0127] Step 201: The QR code identity information center receives the publisher's real-name authentication information and the original QR code information that the publisher needs to display.

[0128] Step 202: The QR code identity information center generates an NFT value based on the real-name authentication information and the original QR code information.

[0129] In some real-time examples, the publisher logs in to the client through a registered account, and the registered account matches the specific secret key of the blockchain; the NFT value is generated based on the real-name authentication information and the original QR code information, including: splicing the real-name authentication information and the original QR code information; performing feature operations on the spliced ​​real-name authentication information and the original QR code information according to the specific secret key to obtain the NFT value.

[0130] Step 203: The QR code identity information center generates target QR code information according to the NFT value and the address information of the QR code identity information center.

[0131] Step 204: The QR code identity information center sends the target QR code information to the client, so that the client generates a target QR code according to the target QR code information.

[0132] Step 205: The QR code identity information center responds to the NFT query request sent by the client, queries whether the NFT value matches the real-name authentication information and the original QR code information, and if it is found that the NFT value matches the real-name authentication information and the original QR code information, the real-name authentication information and the original QR code information are sent to the client.

[0133] In some embodiments, the querying whether the NFT value matches the real-name authentication information and the original QR code information includes: querying the real-name authentication information to be verified and the original QR code information to be verified that match the NFT value; generating the NFT value to be verified based on the specific key, the real-name authentication information to be verified and the original QR code information to be verified; detecting whether the NFT value and the NFT value to be verified are the same; when the NFT value and the NFT value to be verified are the same, the NFT value matches the real-name authentication information and the original QR code information.

[0134] For ease of understanding, the following describes in detail how to generate a QR code and how to verify the QR code in this embodiment with reference to FIG10 to FIG12:

[0135] Please refer to FIG10 , which is a flowchart of the method for generating a QR code provided in this embodiment.

[0136] From step (7.1) to step (7.3), publisher N logs in to the client based on the registered account.

[0137] In step (7.4), the individual or corporate publisher fills in the QR code information through client 1. For example, after successfully logging in to client 1, publisher N enters the QR code publishing page of client 1, and publisher N fills in the original QR code information to be published on this page. Taking the use of QR codes for shared bicycles to scan and unlock and prevent counterfeiting as an example, in order to achieve shared bicycle scanning and unlocking and anti-counterfeiting, publisher N publishes the shared bicycle operation page address (such as: https: / / BikeShare.test.com / user.action) as the original QR code information. It can be understood that the QR code publishing page has a QR code information filling box, and publisher M fills in the content in the QR code information filling box and submits it.

[0138] Step (7.5) Client 1 sends a QR code publishing request to publisher management center 3. That is, client 1 submits the user's QR code publishing request to publisher management center 3, and the QR code publishing request carries the above-mentioned original QR code information.

[0139] Step (7.6) The publisher management center 3 fills in the publisher information. That is, after receiving the QR code publishing request submitted by the client 1, the publisher management center 3 associates the real-name authentication information and specific key information corresponding to the publisher N and adds it to the QR code publishing request.

[0140] Step (7.7): The publisher management center 3 sends a QR code publishing request to the QR code identity information center 2. That is, the publisher management center 3 forwards the supplemented QR code publishing request to the QR code identity information center 2.

[0141] In step (7.8), the QR code identity information center 2 calculates and stores the QR code. Specifically, the QR code identity information center 2 generates an NFT value based on the specific key information, the real-name authentication information, and the original QR code information, and generates the target QR code information based on the NFT value and the domain name address of the QR code identity information center.

[0142] Specifically, after receiving the supplemented QR code publishing request, the QR code identity information center 2 will splice together the original QR code information submitted by publisher N (https: / / BikeShare.test.com / user.action) and the real-name authentication information corresponding to publisher N, and then use the HMAC-Sha256 one-way Hash algorithm to generate the NFT value through the specific secret key corresponding to the account registered by publisher N, and generate the target QR code information based on the domain name address of the QR code identity center and the NFT splicing.

[0143] In addition, the QR Code Identity Information Center 2 will also store the real-name authentication information, the original QR code information, and the time the QR code was issued on the blockchain according to the smart contract. It is understood that NFT values ​​are unique, and each NFT value corresponds to a specific real-name authentication information, original QR code information, and the time the QR code was issued.

[0144] In step (7.9), the QR code identity information center 2 returns the new QR code information and NFT to the publisher management center 3. That is, the QR code identity information center 2 sends the target QR code information to the publisher management center 3. It is understood that the NFT value can also be returned to the publisher management center at the same time.

[0145] In step (7.10), the publisher management center 3 returns the new QR code information and NFT to the client 1. The publisher management center 3 sends the target QR code information to the client 1. It is understood that if the QR code identity information center 2 returns the NFT value to the publisher management center 3 in the above step, the publisher management center 3 will also send the NFT value to the client 1.

[0146] In step (7.11), Client 1 displays the new QR code, pattern, or NFT to the individual or corporate publisher. Specifically, Client 1 has multiple ways to generate the target QR code. Client 1 can display the NFT value and integrate a general QR code generation tool to generate the target QR code; or it can directly use the QR code generation tool to generate the target QR code based on the target QR code information.

[0147] Please refer to FIG11 , which is a flowchart of the QR code verification method provided in this embodiment.

[0148] In step (8.1), the user triggers a scan through client 1. For example, the user initiates a scan using an application D on the terminal device. The application D here can be a scanning tool such as WeChat or Alipay, or a scanning tool client provided by the QR code identity information center.

[0149] Step (8.2) Client 1 parses the QR code information and NFT. That is, application D parses the QR code information based on the QR code pattern.

[0150] Step (8.3) Client 1 initiates an NFT query request to the QR code identity information center 2. That is, application D identifies the URL address of the QR code identity information center through the QR code information and initiates an NFT query request to the QR code identity information center through the browser.

[0151] In step (8.4), the QR code identity information center 2 queries the original QR code information, key, and publisher information stored in the blockchain based on the NFT, and verifies the consistency of the original product QR code information, publisher information, and NFT. That is, after receiving the NFT query request, the QR code identity information center queries the corresponding QR code identity information (i.e., the aforementioned real-name authentication information) and the original QR code information based on the NFT value carried in the URL address, and verifies the consistency of the NFT with the blockchain storage information using the specific secret key corresponding to the publisher account.

[0152] Step (8.5) The QR code identity information center 2 returns the QR code identity information page and the original product QR code information to the client 1. That is, after the QR code identity information center 2 passes the verification, it returns the QR code identity information and the original QR code information to the application D through the HTTPS channel.

[0153] From step (8.6) to step (8.7), application D displays the QR code identity information page to the user. After the user confirms the QR code identity information, clicking Continue will further load the original QR code information.

[0154] In steps (8.8) to (8.13), application D queries the enterprise system for the shared bicycle operation page provided by the enterprise. The enterprise system returns the shared bicycle operation page. The user's terminal device displays the shared bicycle operation page provided by the enterprise. The user performs operations through the shared bicycle operation page. After the operation is completed, the operation request corresponding to the user operation is sent to the enterprise system.

[0155] Please refer to Figure 12, which shows an application scenario where a QR code verification is successful in this embodiment. After a user initiates a scan through a terminal device, the terminal device's display interface first displays the QR code identity information to the user, including but not limited to the aforementioned real-name authentication information, QR code issuance time, and QR code description. After the user clicks Continue, the shared bicycle operation page is displayed to the user.

[0156] Compared with the related art, the embodiments of the present application have at least the following advantages: the target QR code information includes the NFT value and the address information of the QR code identity information center, so that the target QR code generated according to the target QR code information carries less information, which improves the scanning speed, and the NFT value and address information have no actual meaning and are not easy to be identified and forged, thereby improving the anti-counterfeiting effect; in addition, since the NFT value is generated according to the real-name authentication information of the publisher and the original QR code information that the publisher needs to display, and the NFT value is unique, the authenticity of the QR code can be accurately judged by querying whether the identified NFT value matches the real-name authentication information and the original QR code information, further improving the anti-counterfeiting effect of the QR code.
