[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the embodiment of the present application provides a health authentication method based on blockchain and dynamic code, wherein the dynamic code is a built-in rule for generating a string code, which can support time-sensitive coding, and the method includes:

[0022] S101. Determine a pre-created blockchain platform, wherein the blockchain platform includes user nodes.

[0023] Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm. It is essentially a decentralized database.

[0024] First, a blockchain platform created based on a blockchain framework can be determined. The blockchain framework can be any blockchain framework that can implement the corresponding functions of the embodiments of the present application, such as Bitcoin, Ethereum, Fabric, Corda, etc. The blockchain platform can refer to a platform that stores blockchains, for example, a distributed system, etc. Of course, the blockchain platform can also directly represent the blockchain itself, which is not limited here.

[0025] In the blockchain platform, users who need health authentication can be deployed as nodes in the blockchain platform, which can be referred to as user nodes.

[0026] S102: Receive a health authentication request sent by the user node, wherein the health authentication request carries identity information of the user node.

[0027] S103. Determine the service code corresponding to the health authentication request and / or the application ID corresponding to the health authentication request according to the authentication type corresponding to the health authentication request and a preset corresponding relationship.

[0028] In real life, user nodes may need to perform health authentication for various reasons. At this time, the user node can send a corresponding health authentication request to the blockchain platform. Among them, the health authentication request includes the identity information of the user node, the authentication type of the health authentication request, and other information. The authentication type refers to the reason why the user node makes a health authentication request, which can include: returning to work, returning to school, entering and leaving specific places, taking public transportation, etc.

[0029] After receiving the health authentication request, the business code corresponding to the health authentication request can be determined according to the determined authentication type and a preset corresponding relationship, and / or the corresponding application ID can be determined according to the health authentication request.

[0030] Specifically, the main function of the business code is to classify the purpose of the user node application. It can be a unique identifier for a specified business scenario. It can determine the basic properties of the code, such as the validity period and parsing method. It is generally built-in by the system. The corresponding relationship of the preset business code can be set by the generator of the dynamic code, or it can be set by multiple generators or developers after agreeing on rules. The business code can usually consist of uppercase letters, "_", "-" and numbers, for example Figure 3 YWBM shown.

[0031] When determining the application ID, you can first determine the application that the user node sends the health authentication request and the corresponding application when using the health authentication. The application can be an APP on a terminal such as a smartphone or tablet, or an application for various operating systems on a computer, or a mini-program application. Usually, each application will have its corresponding application ID, also known as APPID. The application ID can be used to uniquely identify the corresponding application on the device and in the application store. For example Figure 3 Appak shown in.

[0032] S104. Generate a unique string corresponding to the health authentication request based on the business code, the application ID, at least one of the current timestamp, and the identity information.

[0033] After determining the service code and application ID, a unique string corresponding to the health authentication request can be generated based on at least one of the service code, application ID, and current timestamp, as well as the identity information corresponding to the user node. The timestamp can be the UTC time of the code generation moment, which can be accurate to milliseconds, and has multiple formats such as "YYYYMMDDhhmmssSSS", "YYYYMMDDhhmmss", "YYYYMMDDhhmm", "YYYYMMDDhh", "YYYYMMDD", "YYMMDD", "YYYYMM", "YYMM", etc. The specific format is not limited here, and can be, for example, Figure 3 1582179788 shown.

[0034] Specifically, the identity information may include the user name, ID number, etc. corresponding to the user node. When generating a unique string based on the identity information, the user name and ID number may be concatenated in a corresponding order, and then encoded using a preset encoding method to obtain an identity code, and then a unique string is generated based on the identity code. The corresponding order may be the order of the user name and ID number. When concatenating, a corresponding separator may be added between the user name and the ID number, which may be referred to as the first separator. The first separator may be, for example Figure 3 The "|" in the string may not be added. The preset encoding method may be, for example, Base64, etc., which will not be described in detail here. Figure 3 As shown, the user name is "Zhang XX", the first separator is "|", the ID number is 370101196001012345, and the identity code obtained by Basee64 encoding is 5byg5p+Q5p+QfDM3MDEwMTE2f3.

[0035] After the identity code is obtained, a unique string can be generated according to at least one of the business code, application ID, and timestamp, as well as the identity code. When generating the unique string, it can be directly obtained by splicing, or it can be obtained by splicing after separating each piece of information by a separator, or it can be obtained by symmetrically encrypting the obtained unique string and using the obtained unique encrypted string as the unique string to generate the dynamic code.

[0036] Specifically, you can Figure 3 As shown, the business code, application ID, identity code, and timestamp are arranged in the corresponding order and separated by the second separator (i.e. Figure 3 After separating the "." shown in , a unique string is obtained. Then, the unique string is encrypted by the AES symmetric encryption algorithm and the corresponding encryption key to obtain a unique encrypted string. The encryption key here can be determined by the application ID, that is, the corresponding encryption key is pre-assigned to different application IDs, and the encryption key used at the current moment can be determined according to the pre-assigned corresponding relationship. The unique encrypted string obtained after encrypting the unique string can be as follows Figure 3 As shown in the figure, veTfTaeojawVviVTztUPBTfNOsX…. Among them, due to the length of the unique encrypted string, in order to facilitate the display of the figure, Figure 3 Only some characters of the unique encrypted string are listed, not all of them.

[0037] S105. Generate a dynamic code corresponding to the health authentication request based on the unique string and the corresponding code feature prefix, and write the dynamic code into the blockchain platform as the health code of the user node to facilitate health authentication of the user node.

[0038] After obtaining a unique string, you can add a code feature prefix before the unique string to generate a dynamic code. Of course, if you get a unique encrypted string, you can add a code feature prefix before the unique encrypted string to generate a dynamic code, which will not be repeated here. Among them, the code feature prefix is ​​a specific URL that starts with http and ends with " / ", follows the URL writing rules, and is bound to the application ID. Usually, the dynamic code generated here can be expressed as a QR code, and the common QR code can be a QR code, that is, QR Code, QR stands for Quick Response. After generating the dynamic code, the dynamic code can be used as a health code, and the dynamic code can be written into the blockchain platform for storage, so that the user node can obtain it and perform health authentication. Of course, before writing the dynamic code into the blockchain platform, the dynamic code can be encrypted by the public key of the user node, and then written into the blockchain platform. The user node can obtain the dynamic code after decrypting it with its own private key.

[0039] In one embodiment, the generation process of the dynamic code can also be written into the blockchain platform so that the user node can check the dynamic code. The generation process represents the process from preparing to generating to generating the dynamic code. The corresponding relationship, algorithm, and related data used in this process can be written into the blockchain platform as a generation process, which can specifically include health authentication request, identity information, authentication type, preset corresponding relationship, business code, application ID, timestamp, unique string, and code feature prefix. When the user node is checking, it can first intercept the unique string part from the parameters corresponding to the dynamic code. Of course, if it is the only encrypted string obtained here, it can be decrypted by the encryption key corresponding to the application ID to obtain a unique string. Then the unique string is split by the second separator to obtain the content of each part, and the content of each part is compared to determine whether it is correct. When determining the identity information, if the identity information is an identity code obtained by a preset encoding method, it can be decompiled according to the obtained identity code to obtain the identity information for inspection.

[0040] In one embodiment, the corresponding smart contract can also be pre-generated and deployed in the blockchain platform. Smart contracts can include business coding determination smart contracts, application ID determination smart contracts, unique string generation smart contracts, dynamic code generation smart contracts, and chain writing smart contracts. The business coding determination smart contract is used to: determine the business coding corresponding to the health authentication request according to the authentication type corresponding to the health authentication request and the preset corresponding relationship; the application ID determination smart contract is used to: determine the application ID corresponding to the health authentication request; the unique string generation smart contract is used to: generate a unique string corresponding to the health authentication request according to the business code, the application ID, at least one of the current timestamp, and the identity information; the dynamic code generation smart contract is used to: generate the dynamic code corresponding to the health authentication request according to the unique string and the corresponding code feature prefix; the chain writing smart contract is used to: write the dynamic code as the health code of the user node into the blockchain platform.

[0041] Since the smart contracts on the blockchain platform are public, each node can verify whether the smart contract complies with the pre-agreed agreement and deploy it on its own node. Therefore, while improving the degree of automation, it also increases the trust of each node. Smart contracts can only be changed by upgrading, which requires each node to be deployed synchronously. Once deployed, they can only be executed through programs without interference from human factors, which enhances the credibility of the data.

[0043] at least one processor; and,

[0050] According to the unique string and the corresponding code feature prefix, a dynamic code corresponding to the health authentication request is generated, and the dynamic code is written into the blockchain platform as the health code of the user node to facilitate the health authentication of the user node.
