Detailed Description
The above and further features and advantages of the present invention will be apparent from the following, complete description of the invention, taken in conjunction with the accompanying drawings, wherein the described embodiments are merely some, but not all embodiments of the invention.
Referring to fig. 1, a coding method according to an embodiment of the present invention includes the following steps:
s100, generating a basic screening code for identifying the application, the CA identity of the user on the application and the registration fact according to the application information and the identity information of the user;
and S200, continuously adding the application CA identity and new transaction information of a subsequent user on the basis of the basic screening code in an electronic signature mode during the transaction process, and updating to generate the transaction screening code.
As shown in fig. 2 and fig. 3, the present invention adds an electronic identity authentication and a dynamic electronic signature with legal effect on the basis of a set of data records, and realizes hybrid encoding. Of course, the codes obtained by the coding method provided by the present invention may also adopt other names, and the expression form may be a one-dimensional code, a two-dimensional code, and the like.
The platform of the transaction screening code obtained by the coding method provided by the invention is named as a screening code platform, and the implementation process of the platform is specifically described by taking the screening code as an example.
The basic screening code is used as a screening code chain root, is a basic code applied to the screening code platform, identifies the identity and the registration fact of the application and a main body (namely a user) of the application in the screening code platform, and is a basis for generating a subsequent screening code by the application. The basic screening code mainly comprises application CA identity and application information.
The transaction screening code mainly comprises a previous screening code, the current user CA identity and new transaction information. The third-party application system registered on the screening platform needs to apply for a CA certificate and generate a basic screening code on the screening platform. The user applies for the CA organization through the application on the platform to obtain the electronic signature certificate, and the legal identity of the user on the application is identified. The screening code requires the customer to confirm generation through the CA physical medium UKEY. After the basic screening code is generated, the subsequent transaction screening code for the application can be generated.
As shown in fig. 3, the application information in the screening code (a general term for the basic screening code and the transaction screening code) at least includes: one or more of a service location, a service title, service data, a service time. The business place, namely the place of business transaction, is composed of a coordinate system and longitude and latitude, and the place fact of transaction behaviors is recorded. The business header refers to a concise and readable business transaction name and describes the nature of the transaction. The business data refers to the business transaction original text and describes the specific content of the transaction. The business time refers to the time when the business transaction occurs.
Each electronic signature comprises a screening code signature and a time signature, wherein the screening code signature refers to the signature of the transaction data content and the previous signature data by using a user CA medium UKEY. The time signature means signature confirmation of transaction data by a CA mechanism in time, and the time fact of transaction behavior is recorded. For example, if the expression form of the two-dimensional code is adopted, the finally generated transaction screening code is the screening code two-dimensional code generated by the China two-dimensional code registration authentication center, and is mainly used for code scanning authentication of a main body.
It should be added here that the two-dimensional code is only the last representation. The generation, updating and storage operations in the system all exist in the form of the screening code, and when the screening code in the system needs to be called to display an operating user, the screening code is extracted and displayed in the form of the two-dimensional code.
With reference to fig. 2 and 3, the information of the basic screening code is always preserved. Then, each signature information updates only the content of the middle part (including the CA information of the signature user) shown in fig. 3. After each update, the previous signature information is stored in the database, and the update operation does not affect the retention of the previous signature information.
Further, S100 may specifically be implemented by the following steps:
s110, generating a user identity code according to the valid certificate indicating the user identity and the corresponding valid certificate number;
s120, according to the user identity code, applying to a CA center to obtain an electronic signature certificate of the user;
s130, encrypting the application information and the electronic signature certificate to generate a basic screening code for identifying the application and the CA identity and the registration fact of the user on the application.
The step S110 may use binary codes to encode the valid certificates and the corresponding valid certificate numbers to generate the user identity codes. Such valid documents include, but are not limited to, identification cards, residence certificates, social security cards, passports, drivers licenses, bank cards, and the like.
In order to facilitate safe use, transmission and query of the screening code, the screening code is encoded by using a certain rule and algorithm. The code screening code is unique on the code screening platform and has the characteristics of safety and high efficiency. The screening code can only be generated and verified by a point-pushing screening code platform.
Specifically, the screening code has a length of 9 bytes, and comprises a combined application ID, an in-application ID and an algorithm version number. During encryption, the application ID and the in-application ID can be combined and encrypted by using a Blowfish algorithm to form a coded ciphertext; and the algorithm version number and the coding ciphertext are coded through base64 to form a transaction screening code which is stored in a database, so that subsequent inquiry and verification are facilitated.
Correspondingly, when the screening code is verified, the algorithm version number is firstly analyzed from the code, then the used algorithm is inquired through the version number, the application ID and the in-application screening code ID of the screening code are decrypted by using the Blowfish encryption and decryption algorithm in the algorithm of the version, then the screening code information is obtained through the ID inquiry database, the CA certificate of the user is used for carrying out signature verification on the screening code data, if the signature verification is passed, the screening code verification is successful, otherwise, the verification fails.
The screening code is updated continuously from the basic screening code to generate a chain transaction screening code through continuous electronic signature, so that a complete electronic evidence chain is completed.
It should be noted that, in the evidence chain platform, as the CA user who has authenticated the electronic identity and the relay-type dynamic electronic signature, various off-site economic activities can be performed by using various third-party applications supported by the platform through the mobile client. In the activity of the evidence link system, various behaviors of the user exist in the evidence link system in any one step of operation in the form of electronic signatures, corresponding evidence is left, and the electronic signatures are dynamically embedded into encrypted data codes in a relay manner to finally generate chain transaction screening codes.
The state of the transaction screening code is not static, but dynamically changed throughout the process. After the basic screening code is generated, the user of the platform or each functional department of the government continuously generates a new transaction screening code on the basis of the basic screening code for the authentication signature of the state change in each step during the activity, and the updating record of the transaction screening code corresponds to the generation process of the whole evidence chain, so that a controllable, traceable and reliable evidence chain is formed.
According to the coding method provided by the invention, when the basic screening code of the identification application, the CA identity of the user on the application and the registration fact is generated in the transaction process according to the application information and the identity information of the user, the application CA identity and new transaction information of the subsequent user are continuously added on the basis of the basic screening code in an electronic signature mode, and the generated transaction screening code is updated. The method comprises CA electronic identity authentication with legal effect, and generates a chain transaction screening code through continuous electronic signature and continuous updating to form a complete electronic evidence chain. The coding method and the coding system provided by the invention can better realize the association between specific application and user identity, and simultaneously can realize the mutual correction of a plurality of groups of data, and are not easy to crack or copy, thereby forming a reliable evidence chain.
Based on the same inventive concept, the invention also provides a coding system. The principle of the coding system is the same as that of the coding method, so the implementation of the coding system can be realized by referring to the method, and the repetition part is not described redundantly.
