Aiming at the problem of the low reliability of the resume information provided by individuals in the field of talent recruitment in the prior art, the embodiment of the present application provides a resume information management method that uses a decentralized distributed storage provided by a blockchain to record users Since the resume information uploaded to the blockchain cannot be tampered with and can be traced back, the problem of poor reliability of the resume information is fundamentally solved.

The embodiment of the present application provides a method for managing history information.

Specifically, please refer to FIG. 1, the method includes the following steps:

S102. Obtain contract information uploaded by an information source to the blockchain.

The contract information is the employment contract signed between the individual user and the employer, and its expression can include but is not limited to: contract and so on.

S104. Package the contract information into blocks.

S106: Broadcast the entire network of the block, so that each node in the block chain adds the block to the history information block chain.

The contract information can prove that an individual user establishes an employment contract with an employer, and the contract information can be added to the user's resume information blockchain.

The information source in the embodiments of the present application is not particularly limited. For example, the information source may be an individual user, or an employer that has signed an employment contract with an individual user, or may be a national personnel management agency.

The block chain involved in the embodiment of the present application may be a national personal history query exclusive chain. Among them, the proprietary chain is a kind of alliance chain, which only targets members of a certain group and a limited number of third parties. It internally designates multiple pre-selected nodes as bookkeepers. The generation of each block is jointly determined by all pre-selected nodes. Other access nodes can participate in the transaction, but just ask the accounting process, and other third parties can make limited queries through the open API of the blockchain. The national personal resume query private chain is a proprietary chain for querying national personal resume information.

The solutions involved in the embodiments of the present application can be implemented by smart contract technology in the blockchain.

In the field of blockchain technology, smart contracts specifically refer to computer programs that are triggered based on predetermined events, cannot be tampered with, and are automatically executed. Nodes on the blockchain can implement various transactions by calling smart contracts.

Among them, smart contracts are generally divided into two types according to the different ways of creating and functioning smart contracts. One is the built-in smart contract of the system, which is characterized by the existence and provision of services after the creation of the blockchain node; the other is the user's external smart contract, which is characterized by the user's invocation of the blockchain node's API interface. New smart contract created. The smart contracts involved in the embodiments of the present application can be implemented in the above two ways.

In the embodiment of the present application, any node can receive the information uploaded by the information source. However, considering the particularity of the contract information, there is a risk of being leaked. Therefore, when uploading, the identity of the information source can also be verified. In order to prevent other users who do not have contract information from uploading data maliciously, causing data errors and affecting talent recruitment.

Based on this, referring to FIG. 2, before performing step S104, the following steps may also be included:

S103. Perform identity verification on the information source.

Therefore, when the information source is verified as a reliable information source, the step of packaging the contract information into blocks in S104 is performed; or, when the information source is verified as a non-reliable information source, and the verification fails, it may be output to indicate the identity If the verification fails, you can directly end.

In the actual implementation process, what kind of information source authentication can be passed can be set as required.

In a specific application scenario, the reliable information source may include, but is not limited to, a national personnel management agency or a contract signing party corresponding to the contract information.

That is, when the identity verification result of the information source is a person or institution related to the contract information, such as the parties to the contract information or the national personnel management agency, the identity verification can pass; otherwise, the other has nothing to do with the contract information Of users are more difficult to authenticate.

That is, S103 is mainly to verify whether the identity of the information source is a reliable information source. This step can be implemented based on digital signatures in blockchain technology.

In the field of blockchain, each user has a pair of asymmetric keys. Asymmetric keys are composed of public and private keys. Because public and private keys are not the same, they are called asymmetric keys. In actual use, the content encrypted with the public key in a pair of asymmetric keys can only be decrypted with the private key in the same pair of asymmetric keys, and the content encrypted with the private key can only be decrypted. The corresponding public key is decrypted. In general, the user's private key is only known to the user, and the public key can be stored on each node in the blockchain.

Therefore, using the asymmetric encryption algorithm of public key and private key, the data uploaded by the data uploader by the public key and uploaded to the blockchain can only be decrypted by the data uploader's private key; and, the data can be made The uploader encrypts the data encrypted by the private key and uploads it to the blockchain. The data can only be decrypted by the public key of the uploader, which can ensure the security of the data to a certain extent.

Based on this, in the blockchain, the user information is encrypted by using the private key to obtain the user's digital signature. Then, by verifying the digital signature, the identity of the user can be determined.

Therefore, when the user's identity is verified, the user's public signature can be used to decrypt the digital signature. If the decryption is successful, the user information can be obtained; otherwise, if the decryption is unsuccessful and the authentication fails, the user information cannot be obtained .

Therefore, when the verification step of S103 is performed, the public signature of the trusted information source can be used to decrypt the digital signature of the verified information source. If the decryption is successful, the verification is passed, indicating that the information source is a reliable information source; otherwise, it is decrypted Unsuccessful, verification failed, indicating that the information source is an unreliable information source.

In the process shown in FIG. 1 or FIG. 2, when step S104 is performed, it can be implemented by the following steps: existence verification processing and time stamp processing are performed on the contract information to obtain a block.

Among them, when the contract information is packaged into blocks, the existence proof processing and time stamp processing are performed on it. Wherein, the existence proof processing method involved in the embodiment of the present application may include, but is not limited to, a hash algorithm processing. Timestamp processing adds the current time to the block header for a block. A timestamp is unique to a contract message and cannot be forged. And the historical data (historical blocks) added to the blockchain are unchangeable and cannot be deleted, so the history of the resume information is guaranteed to be traceable.

When the contract information is actually stored on the history information blockchain, the execution timing of the existence information processing and the timestamp processing on the history information is not particularly limited, and may be performed simultaneously, or may be performed in a certain order.

In addition to recording and storing the user's resume, the method for managing resume information provided in the embodiments of the present application can also meet the inspection requirements required during the recruitment process.

In this regard, reference may be made to FIG. 3, and the method may further include the following steps:

S302. Receive a history information query request sent by a target node in the blockchain.

S304: Determine target history information of the target user indicated in the history information query request.

S306: Verify the digital signature of the target node, and obtain the target node's access permission for the target history information.

S308A, when the target node has the viewing authority, output target history information.

on the contrary,

S308B, when the target node does not have the access permission, output a prompt message for prompting the target node to request the target user for the access authorization.

It can be known that S308A and S308B in FIG. 3 are two parallel processes. After executing S306, S308A and S308B can be executed one by one.

When the target history information is output, different operations can be performed based on different types of users having different viewing rights. Specifically, different types of viewing permissions can be set for different users, and the permissions and completeness of the resume information that can be viewed by each viewing permission are different.

In order to facilitate understanding, the embodiment of the present application provides a feasible implementation manner as follows: according to three different types of users: individual users, employers, and national personnel management agencies, set different access permissions for them:

When the target node is an individual user, the target node has a first inspection authority, and the first inspection authority is used to inspect the personal resume information of the individual user; or,

That is, individual job applicants only have access to their own resume information. When the target resume information in the resume information review request issued by them is their resume information, they can execute the step of outputting the target resume information in S308A above. Or, when the requested target resume information is the resume information of other individual job applicants, the operation of prompting the target node to request authorization from the target user in S308B may be performed.

And, for the employer, users who have signed an employment agreement with the employer are contract users, users who have not signed an employment agreement with the employer, and users whose employment agreement has expired are non-contract users.

Then, when the target resume information requested by the employer is the resume information of the contract user, the step of outputting the resume information in S308A can be performed, and the entire resume information of the contract user is output; otherwise, when the employer requests When the target history information that is consulted is the history information of the non-contracted user, the step of outputting the history information in S308A can be performed, and the partial history information of the non-contracted user is output, that is, The public part and the privacy part need to be authorized by the non-contract user to view.

In addition, for the national personnel management agency, regardless of the person's resume information requested by the person, it has the access authority to access all the resume information of the target user.

The above permission setting method is a feasible implementation method. In the actual application process, the access permission can also be set in other ways, which is also within the protection scope of the management method of this solution.

And, the manner of outputting the information in S308 may include, but is not limited to, outputting historical information for viewing only, and / or outputting historical information available for downloading. In the actual implementation process, it can be set as required.

In a specific implementation scenario, the blockchain involved in the embodiments of the present application may be a personal resume information exclusive chain.

Based on the above method, the present application also provides a computer non-volatile readable storage medium. The non-volatile readable storage medium includes a stored program, and the non-volatile readable storage is controlled when the program runs. Perform the following steps on the device where the media is located:

Optionally, when the program is running, controlling the device where the non-volatile readable storage medium is located further performs the following steps: performing existence proof processing and time stamp processing on the contract information to obtain the block.

Optionally, when the program is running, controlling the device where the non-volatile readable storage medium is located further performs the following steps: before the packaging of the contract information into blocks, identity verification of the information source; when When it is verified that the information source is a reliable information source, the step of packaging the contract information into blocks is performed; when it is verified that the information source is a non-reliable information source, the verification fails, and the output is used to prompt identity verification Failure message.

Optionally, when the program is running, controlling the device where the non-volatile readable storage medium is located further performs the following steps:
