Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart illustrating a method for processing blockchain data according to an embodiment of the present invention, where the method is applicable to a situation where data operations are performed on a blockchain, and the method can be executed by a blockchain data processing apparatus configured on a blockchain application. As shown in fig. 1, the method specifically includes the following steps:

and step 110, processing the target data according to the user operation.

The user performs operation on target data on the blockchain application as required, the blockchain application receives a data operation request of the user and processes the target data, and the target data is an operation object of the user. For example, the user may perform an editing operation such as addition or deletion of data in the blockchain application, or may perform a transaction operation in the financial field or the insurance field, and store the processing result of the target data.

Step 120, obtaining a user eID identification associated with the blockchain application from the eID server.

The method comprises the steps that after an eID index is obtained by a block chain application, a user eID identification obtaining request is sent to an eID server, the user eID identification obtaining request carries an eID index unique to a user, the eID index is obtained from eID modules capable of being in communication connection through the block chain application, each eID module can be equipment belonging to different users, and the eID index and a user key of the user are included. And the eID server searches for the user eID identification associated with the block chain application and the eID index and sends the user eID identification to the block chain application. The eID index is unique, and the eID identification can be changed according to different block chain applications.

Optionally, before obtaining the user eID identifier associated with the blockchain application from the eID server, the method further includes: and sending the attribute information of the block chain application to an eID server for indicating the eID server to establish an association relation between the eID index under the block chain application and the eID identifier of the user.

Specifically, the blockchain application is registered in an IDSP (Identity Service Provider), connected with an IDSP background according to an eID standard, and applies for eID services. The eID server receives attribute information of different blockchain applications, wherein the attribute information can comprise developers, development companies, network addresses and the like of the blockchain applications. After the block chain application is registered, the application of eID service is completed, and the eID server generates the association relation between the eID index and the eID identification of the user under different block chain applications. That is, under different blockchain applications, the same eID index corresponds to different user eID identifiers. For example, two block chain application attribute information, namely a block chain application a and a block chain application B, exist in the eID server, the eID index of the user is 001, under the block chain application a, the user eID identifier corresponding to the eID index 001 is 1, and under the block chain application B, the user eID identifier corresponding to the eID index 001 is 2. Different user eID identifications are used under different block chain applications, so that the problems of information leakage and the like caused by stealing of the user eID identifications can be prevented, and the protection of user privacy and information safety is facilitated.

Optionally, the eID index of the user is obtained from the connected eID module; the eID index is sent to an eID server to instruct the eID server to determine a user eID identification associated with the blockchain application and the eID index.

Specifically, communication connection can be established between the eID module and the block chain application, and after the eID module and the block chain application complete the establishment of the communication connection, the block chain application sends an eID index acquisition request to the eID module. The method comprises the steps that after an eID module receives an eID index acquisition request of a block chain application, an unique eID index in the eID module is sent to the block chain application, an eID index is stored in each eID module, and the eID module can be specially used for a user of the eID index. After receiving the eID index, the block chain application sends the eID index to an eID server, and sends a user eID identification acquisition request comprising the eID index to the eID server. And after receiving the user eID identification acquisition request, the eID server searches for the user eID identification associated with the eID index under the block chain application, and sends the user eID identification to the block chain application. By obtaining the eID index from the eID module, the accuracy of the eID index is ensured, and errors in searching the eID identification of the user are avoided.

Step 130, determining a hash result of the target data, and generating an application signature instruction comprising the hash result.

After receiving operation processing of a user on target data, the block chain application processes the target data according to a Hash algorithm and determines a Hash result of the target data. And after determining the hash result, the block chain application generates a signature application instruction carrying the hash result. The hash result of the target data calculated by the blockchain application may be before the user eID is obtained or after the user eID is obtained.

Step 140, sending a signature application instruction to the eID server to instruct the eID server to execute the following steps: checking a message applying a signature instruction; and if the verification is passed, generating a signature instruction comprising the hash result.

The method comprises the steps that a block chain application sends a signature applying instruction comprising a Hash result to an eID server, the eID server receives the signature applying instruction sent by the block chain application, and a message applying the signature instruction is verified according to a message verification rule in the eID server. If the message of the application signature command conforms to the message verification rule, the verification is passed, and the eID server generates the signature command carrying the hash result. If the message for applying the signature command does not accord with the message verification rule, the verification fails, and the eID server sends a signature forbidding command to the block chain application.

And step 150, if the signature instruction is received from the eID server, sending the signature instruction to the eID module to instruct the eID module to determine signature data according to the hash result and the user key.

The eID server sends the signature instruction including the hash result to the block chain application, and after the block chain application receives the signature instruction including the hash result, the eID server sends the signature instruction including the hash result to the eID module. After the eID module receives the signature command, the user can input the use password of the eID module on the eID module, if the password is correctly input, the user obtains the use permission of the eID module, and the eID module can calculate the signature data. The eID module obtains a hash result in the signature instruction, determines signature data of a user according to a user key and the hash result in the eID module, and sends the signature data to the block chain application.

And step 160, writing the processing result of the target data, the eID of the user and the signature data into a block chain in an associated manner.

The eID module sends signature data to the block chain application, the eID server sends a user eID identification to the block chain application, and the block chain application associates a processing result of the target data, the user eID identification and the signature data and writes the processing result, the user eID identification and the signature data into the block chain for storage. For example, if the processing result of the target data is 000, the user eID is identified as 1, and the signature data is 2, the content to be stored in the block chain is 000/1/2.

Optionally, after writing the processing result of the target data, the user eID identifier, and the signature data in the block chain in an associated manner, the method further includes: responding to an eID verification instruction of a user, sending a signature data verification request at least comprising signature data to be verified, a hash result of the data to be verified and an eID mark of the user to an eID server to indicate the eID server to verify; and receiving a verification result sent by the eID server.

Specifically, the blockchain application has a traceability function, and a user can search for the signature data stored before and verify the signature data stored before. The method comprises the steps that a block chain application responds to an eID verification instruction sent by a user and sends a signature data verification request to an eID server, wherein the signature data verification request at least comprises signature data to be verified, a Hash result of the data to be verified and a user eID, and the Hash result of the signature data to be verified and the Hash result of the data to be verified are the signature data and the Hash result of the part of the block chain to be verified. And the eID server receives a signature data verification request sent by the block chain application and searches a user key according to the eID identification of the user. The user key may be symmetric encryption or asymmetric encryption, for example, the user public key in asymmetric encryption. And verifying the signature data to be verified in the signature data verification request according to the user key to obtain a hash result to be verified of the signature data to be verified. Comparing the hash result of the data to be verified with the hash result to be verified, and if the comparison result is consistent, the signature data is correct; if the comparison result is not consistent, the signature data has a problem. And the eID server sends the verification result to the block chain application, and the block chain application receives the verification result and displays the verification result to the user. By sending the signature data verification request to the eID server by the block chain application, the signature data is traced and verified, the requirement for monitoring the data is favorably met, and the data protection degree and the data verification efficiency are improved.

According to the technical scheme, the target data are processed through user operation on the block chain application, user eID identification related to the block chain application is obtained from an eID server, a hash result of the target data is calculated, a signature application instruction carrying the hash result is sent to the eID server, and a signature instruction of the eID server is received. And sending the signature instruction to an eID module, calculating the signature data of the user by the eID module, and writing the processing result of the target data, the eID identification of the user and the signature data into a block chain after the block chain is applied to receiving the signature data. The problem of among the prior art, the user identity of data on the unable verification block chain is solved, adopt signature data to mark user identity for data on the block chain, signature data can avoid user identity to reveal at will. Through the traceable function of the block chain, the eID identification and the signature data of the user are checked, and the supervision requirements on the user and the data are met.

step 210, sending the user eID identification associated with the blockchain application to the blockchain application.

The eID server receives an eID index sent by the block chain application, searches for a user eID mark associated with the block chain application and the eID index, and sends the user eID mark to the block chain application. The eID index is acquired from the eID module by the block chain application, and an eID index is stored in the eID module. The eID server can establish an association relation between eID indexes under different block chain applications and user eID identifications according to attribute information of the block chain applications received in advance, and after the eID indexes sent by the block chain applications are received, the user eID identifications are searched according to the association relation.

Step 220, receiving a signature application instruction sent by the block chain application, and checking a message of the signature application instruction.
