[0028] It is judged whether the relationship between the block uploading the temporary certificate and the user in the block exists in the trusted area, if yes, the verification is passed, otherwise, the verification is not passed.

[0029] From the above description, when the relationship between the block and the user is not trusted, the block user is not allowed to process the data, thereby ensuring the security of the data.

[0058] Embodiment one

[0059] Please refer to Figure 1 A block data verification backtracking method comprises the following steps:

[0060] S1, obtaining the uploaded data and operation behavior of a user who joins a block in the block, issuing a temporary certificate according to the uploaded data, and sending the temporary certificate and the operation behavior to a server.

[0061] Specifically, after a user joins a block, the user uploads data to the block and operates the data. In this embodiment, the data can include image data, file data, text data, etc., and the operation can include adding, accessing, deleting, modifying, etc.

[0062] Further, the block takes the data type of the uploaded data as the header data of the temporary certificate, and adds the user information of the user corresponding to the uploaded data in the certificate data of the temporary certificate.

[0063] Specifically, the block acquires the data type of the uploaded data, takes the data type as the header data of the temporary certificate, and takes the user information as the certificate data. The user information includes the user IP, the current time, the current hardware information, and the current location.

[0064] S2, verifying the block that uploads the temporary certificate in the server, when the verification is passed, judging whether the temporary certificate is a formal certificate in the certificate issuing server, if yes, adding the operation behavior of the user as a sub-member of the formal certificate, otherwise, parsing the temporary certificate, and issuing a formal certificate according to the parsing result.

[0065] Specifically, the server receives the block data, and first verifies the block. In this embodiment, a trusted area is set for the block. The trusted area includes a trusted area path and a trusted member. The trusted area path includes a path identifier (i.e. block information) and a path member (i.e. user information), and the trusted member has its corresponding certificate. Therefore, it is judged whether the relationship between the block and the user exists in the trusted area, if yes, the verification is passed, otherwise, the verification is not passed.

[0066] Further, when the verification is passed, it is judged whether the temporary certificate is a formal certificate in the certificate issuing server. In the embodiment, the certificate issuing server stores a plurality of formal certificates, and the server currently in use can only operate the data corresponding to the formal certificates after being authorized by the certificate issuing server. In this way, it is convenient to verify the source and integrity of the data in a safe and reliable manner.

[0067] When the temporary certificate belongs to the formal certificate, the operation behavior of the user is added as a sub-member of the formal certificate. Specifically, an access tag can be added to the formal certificate, and the operation behavior of the user is recorded in the access tag, which can provide a reference and a time change period when the data changes, so as to prove the legitimacy of the data.

[0068] When the temporary certificate does not belong to the formal certificate, the certificate information is generated and the certificate path is recorded according to the data submitted by the block, that is, the data type and user information of the uploaded data are parsed from the temporary certificate, the trust zone path of the trusted zone of the block is obtained, wherein the trust zone path contains the associated block and user information, and then the formal certificate is established in combination with the data type, user information and trust zone path.

[0069] Therefore, only the servers and blocks that have passed the verification and authorization can participate in the modification and management of the data, thereby preventing unauthorized access and tampering.

[0070] S3, backtracking the block data according to the sub-members of the formal certificate.

[0071] Specifically, the operation behavior of each user on the block data is obtained by obtaining the sub-members of the formal certificate. In the embodiment, the issuance of the certificate can provide a reference for the original data of the block, and the data (time, hardware information, location) in the sub-member can provide a reference for the data access and modification.

[0072] Embodiment two

[0073] Please refer to Figure 2 A block data verification and backtracking system includes blocks and servers, the blocks implement each step in a block data verification and backtracking method with the blocks as the main body, and the servers implement each step in a block data verification and backtracking method with the servers as the main body.

[0074] In summary, the block data verification and backtracking method and system provided by the application obtains the uploaded data and operation behavior of the user who joins the block in the block, issues a temporary certificate according to the uploaded data, and sends the temporary certificate and the operation behavior to the server. The server verifies the block after receiving the temporary certificate, and if the verification is passed, it is judged whether the temporary certificate is a formal certificate in the certificate issuing server. If yes, the operation behavior of the user is appended to the sub-member of the formal certificate, otherwise, the temporary certificate is parsed, and a formal certificate is issued according to the parsing result, and then the data backtracking can be realized through the sub-member of the formal certificate. In this way, the server and the block can be verified in the verification process, and only the formal certificate of the data to be traced is needed in the backtracking process to realize data backtracking, which can reduce the resource consumption of block data verification and improve the backtracking efficiency of block data.

[0075] The above is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent transformation or direct or indirect application in the related technical field based on the content of the specification and drawings is also included in the patent protection scope of the application.
