The management server can send registration confirmation information to the uploading terminal after distributing the user identification and the asymmetric key to the uploading user, and the uploading terminal can confirm that the registration is successful after receiving the registration confirmation information.

Step 503, the management server uplinks and stores user key information of the uploading user in the target block chain node, where the user key information includes a user identifier of the uploading user and a public key of the uploading user.

After the uploading terminal successfully registers on the management server, the management server may uplink user key information of the uploading user to a target block chain node, where the target block chain node may be any block chain node distributed on the block chain platform, and the user key information may include a user identifier of the uploading user and a public key of the uploading user. Alternatively, the management server may send the user key information to the target blockchain node through a communication connection with the target blockchain node, so that the target blockchain node stores the user key information.

Optionally, the management server may also send the private key of the uploading user to the uploading terminal, which is not limited in this embodiment of the present application.

Step 504, the target blockchain node synchronizes the broadcast of the user key information to a plurality of blockchain nodes on the blockchain platform.

Optionally, the target blockchain node may send the user key information to each blockchain node on the blockchain platform, so that each blockchain node on the blockchain platform can store the user key information, thereby synchronizing the broadcast of the user key information to a plurality of blockchain nodes on the blockchain platform.

In this embodiment of the present application, a target blockchain node may send the user key information to each blockchain node on a blockchain platform, after receiving the user key information, any blockchain node may perform consensus processing on the user key information through a consensus algorithm, and then broadcast the user key information to the blockchain platform again, and continuously execute the consensus processing until the user key information stored in each blockchain node is consistent, so that consistency of the user key information stored in each blockchain node can be ensured.

And 505, the uploading terminal sends a storage request to the management server, wherein the storage request comprises the user identification of the user to be investigated and the third resume information of the user to be investigated.

Wherein the third resume information may include at least one of work resume information or education resume information. The work resume information can comprise at least one of the original enterprise name, the time of job entry, the time of job departure, the position, the reason of job departure or whether the competitive industry is forbidden; the education biographical information may include at least one of a name of a graduate institution, a time of admission, whether graduate, a time of graduate, or whether a division was past at the graduate institution.

In the embodiment of the present application, when a user to be surveyed leaves the job from an original enterprise or graduates from an institution, an uploading user (that is, the original enterprise or the graduate) may provide resume information to the user to be surveyed, and the providing of the resume information by the uploading user to the user to be surveyed is referred to as third resume information of the user to be surveyed in the embodiment of the present application. And the uploading terminal may generate a storage request according to the user identifier of the user to be investigated and the third history information, and transmit the storage request to the management server, where the storage request includes the user identifier of the user to be investigated and the third history information. Alternatively, the uploading terminal may send the storage request to the management server through a communication connection with the management server.

Step 506, the management server signs the third resume information according to the private key of the uploading user to obtain the second resume information of the user to be investigated.

The management server can receive the storage request sent by the uploading terminal, analyze the storage request to obtain the user identifier and the third history information of the user to be investigated, and sign the third history information by adopting the private key of the uploading user to obtain the second history information of the user to be investigated.

Alternatively, the management server may extract the digest of the third history information to obtain the digest of the third history information, and sign the digest of the third history information with the private key of the uploading user to obtain the second history information of the user to be investigated, so that the data size of the second history information may be reduced.

The technical personnel in the field can easily understand that the information signed by the private key can only be signed by the corresponding public key, and the second resume information is obtained by the management server by signing the third resume information by the private key of the uploading user, so that the second resume information can only be signed by the public key of the uploading user, the resume information of the user to be investigated can be prevented from being leaked, and the safety of the resume information of the user to be investigated can be ensured.

Step 507, the management server links and stores the user history information of the user to be investigated in the target block link node, wherein the user history information includes the user identifier and the second history information of the user to be investigated.

After obtaining the user identifier of the user to be investigated and the second history information of the user to be investigated, the management server may generate the user history information of the user to be investigated according to the user identifier of the user to be investigated and the second history information, and link and store the user history information in the target block chain node, where the user history information may include the user identifier of the user to be investigated and the second history information.

Alternatively, the management server may send the user history information to the target block chain node through a communication connection with the target block chain node, and the target block chain node stores the user history information after receiving the user history information.

Step 508, the target blockchain node synchronizes the broadcast of the user biographical information to a plurality of blockchain nodes on the blockchain platform.

After receiving the user history information of the user to be investigated sent by the management server, the target blockchain link point may send the user history information to each blockchain node on the blockchain platform, so that each blockchain node on the blockchain platform can store the user history information, thereby synchronizing the user history information broadcast to a plurality of blockchain nodes on the blockchain platform.

In this embodiment, the target block chain node may send the user history information to each block chain node on the block chain platform, after receiving the user history information, any block chain node may perform consensus processing on the user history information through a consensus algorithm, and then broadcast the user history information to the block chain platform again, and continuously perform the consensus processing until the user history information stored in each block chain node is consistent, so that consistency of the user history information stored in each block chain node can be ensured.

In step 509, the survey terminal sends a survey request to the management server, where the survey request includes the user identifier of the user to be surveyed and the first history information of the user to be surveyed.

The survey user can be a job-seeking enterprise of the user to be surveyed. When a user to be investigated seeks a job for the investigation user, the resume information of the user to be investigated and the user identifier of the uploading user can be provided for the investigation user, and the investigation user can be authorized to carry out resume investigation on the user to be investigated.

After obtaining the survey authorization of the user to be surveyed, the survey terminal may send a survey request to the management server, where the survey request may include the user identifier of the user to be surveyed and the first resume information of the user to be surveyed, and the survey request may further include the user identifier of an uploading user (i.e., the original enterprise or the graduate of the user to be surveyed), and the survey request is used to request the management server to perform resume survey on the user to be surveyed. Alternatively, the survey terminal transmits a survey request to the management server through a communication connection with the management server.

Step 510, the management server sends a query request to the target block chain node according to the survey request, wherein the query request comprises the user identifier of the user to be surveyed and the user identifier of the uploading user.

The management server may receive a survey request sent by the survey terminal, analyze the survey request to obtain a user identifier of the user to be surveyed, the first resume information, and a user identifier of the uploading user, then generate an inquiry request according to the user identifier of the user to be surveyed and the user identifier of the uploading user, and send the inquiry request to the target block chain node, where the inquiry request may include the user identifier of the user to be surveyed and the user identifier of the uploading user. Alternatively, the management server may send the query request to the target blockchain node through a communication connection with the target blockchain node.

Step 511, the target block chain node queries the second resume information on the block chain platform according to the user identifier of the user to be investigated, and queries the public key of the uploading user on the block chain platform according to the user identifier of the uploading user.

The target block chain node can receive the query request sent by the management server, analyze the query request to obtain the user identifier of the user to be investigated and the user identifier of the uploading user, then query the second resume information of the user to be investigated on the block chain platform according to the user identifier of the user to be investigated, and query the public key of the uploading user on the block chain platform according to the user identifier of the uploading user.

Optionally, the process that the target blockchain node queries the second resume information of the user to be investigated on the blockchain platform according to the user identifier of the user to be investigated may include: and when the node does not have the second history information of the user to be investigated, the target block chain link point inquires the second history information of the user to be investigated on the block chain platform except the node according to the user identification of the user to be investigated. Optionally, the target blockchain node may send the user identifier of the user to be investigated to other blockchain nodes except the target blockchain node in the blockchain platform, after the other blockchain nodes receive the user identifier of the user to be investigated, the second history information of the user to be investigated is locally queried at the other blockchain nodes according to the user identifier of the user to be investigated, and so on until the second history information of the user to be investigated is queried, or until all blockchain nodes on the blockchain platform are traversed. The process of querying the public key of the uploading user on the block chain platform by the target block chain node according to the user identifier of the uploading user is similar to that described above, and is not repeated here.

And step 512, the target block chain node feeds back the second resume information and the public key of the uploading user to the management server.

After querying the second history information of the user to be investigated and the public key of the uploading user, the target block chain node may feed back the second history information and the public key of the uploading user to the management server, and optionally, the target block chain node may feed back the second history information of the user to be investigated and the public key of the uploading user to the management server through a communication connection with the management server.

And 513, the management server checks and signs the second history information according to the public key of the uploading user to obtain third history information.

Optionally, the management server may receive second history information of the user to be investigated and a public key of an uploading user, which are sent by the target block chain node, decrypt the second history information by using the public key of the uploading user to obtain decrypted information, compare the decrypted information with third history information of the user to be investigated, and when the decrypted information is the same as the third history information of the user to be investigated, the management server determines that the signature verification is successful, and the decrypted information is the third history information.

In step 514, the management server verifies the first history information based on the third history information.

Alternatively, the management server may compare the first history information with the third history information to verify the first history information.

Step 515, the management server feeds back the investigation result to the investigation terminal.

After the management server verifies the first history information, the survey result may be generated and fed back to the survey terminal. The survey result may be that the first history information is the same as the third history information, or the first history information is different from the third history information, and may indicate different contents of the first history information and the third history information, for example, the time of departure included in the first history information is different from the time of departure included in the third history information, and the like, and the details of the first history information and the third history information are not repeated herein in this embodiment of the present application.

In the embodiment of the application, the management server may interact with the blockchain platform for different users, for example, the management server interacts with the blockchain nodes at the request of the uploading terminal to be regarded as the management server interacts with the blockchain platform for the uploading user, the management server interacts with the blockchain nodes at the request of the survey terminal to be regarded as the management server interacts with the blockchain platform for the survey user, the interaction between the management server and the blockchain platform may call intelligent contracts, in the process that the management server interacts with the blockchain platform for different users, the management server may count the times of calling the intelligent contracts for different users, determine the frequency of using the resume management platform (management server) by different users according to the times of calling the intelligent contracts for different users, and provide different excitation mechanisms for different users according to the frequency of using the resume management platform by different users, so as to improve the enthusiasm of the users for using the survey platform. The incentive mechanism may be, for example, allowing the user to use the history management platform for a fixed time period for free, or rewarding the user with a certain amount of resources (for example, virtual coins, coupons, and the like), where the resources can reduce the cost for the user to use the history management platform, and the like, and the embodiments of the present application are not described herein again.
