Detailed Description
In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure. It is to be understood that the described embodiments are only a few, and not all embodiments. All other embodiments that can be derived by one of ordinary skill in the art from one or more embodiments of the disclosure without making any creative effort shall fall within the scope of the disclosure.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification. Rather, they are merely examples of systems and methods consistent with aspects of the present description.
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
In the field of talent recruitment, the user units often need to verify the past experience provided by job seekers; for example, if a job seeker gives his work experience at another company, the human entity needs to confirm with the other company whether the information provided by the job seeker is accurate; if the job seeker gives information such as his/her score and award during the school, the user unit needs to visit the corresponding school for relevant data.
During specific implementation, a user unit can require a job seeker to synchronously submit a paper certificate document with a official seal when submitting job hunting materials such as resumes and the like, such as a score certificate, a prize winning information certificate and the like issued by a school for the job seeker; however, when issuing a certificate, it is necessary to certify as much information as possible in one certificate in order to improve office efficiency, and a human unit may not need much information, which may lead to leakage of privacy.
Referring to fig. 1, fig. 1 is a diagram illustrating a scenario of information disclosure in related art shown in this specification; in this example, if the job seeker needs to put resumes to the person using unit a, the person using unit B, and the person using unit C, and each person using unit needs to have a difference in the certification information, so that the target job seeker can only take three kinds of certification documents, namely, the school certification _1, the school certification _2, and the school certification _3, from the school, it can be presumed that the combination of the above three kinds of certification documents may satisfy the certification requirement of the person using unit for the target job seeker's information at the school, but there may be three kinds of certification documents that also include additional privacy information that is actually not needed by the person using unit;
for example, suppose that the employing unit A needs to know the computer professional course scores of the students, and the employing unit B needs to know the general course scores of the students; if the school certification _1 contains the scores of all courses, the target job seeker shows the file of the school certification _1 to the employing unit A, and the recognized course scores are disclosed to the employing unit A accidentally; similarly, when the target job seeker presents the file school identification _1 to the human entity B, then their computer professional course achievements are unexpectedly revealed to the human entity B; this also leads to leakage of private information.
That is, there is a problem that efficiency and privacy cannot be simultaneously achieved in the related art implementation scheme.
Based on this, the specification provides a technical scheme that a decentralization identity of a job seeker is established in a block chain, and a school is used for chaining on-school information of the job seeker and storing the decentralization identity in a correlation mode, so that the block chain can issue a verifiable statement for proving the authenticity of part of on-school information to the job seeker, and the job seeker can conveniently prove the authenticity of the corresponding part of on-school information to a human unit in a mode of showing the verifiable statement.
In practice, the job seeker can check the verifiable statement against the list of information to be disclosed given by the personnel unit and present the verifiable statement to the personnel unit only without constituting additional privacy disclosure, thereby ensuring that the personnel unit will only obtain the necessary information of the employee seeker at the current time without knowing other privacy information of the job seeker.
In the above technical solution, on one hand, since the document for verifying the decentralized identity registered by the target job seeker and the pieces of on-school information of the target job seeker uploaded and stored by the school office platform are pre-stored in the block chain, and the first verifiable statement bound with the decentralized identity is pre-issued to the target job seeker, the target job seeker can directly show the first verifiable statement to the staff without applying for paper certification and sealing again to the school; therefore, the scheme can remarkably improve the efficiency of completing the whole information disclosure process.
On the other hand, the target job seeker needs to determine that the first verifiable statement held by the target job seeker does not contain redundant private information except the to-be-disclosed information indicated in the list of the to-be-disclosed information issued by the human unit to the target job seeker, so that the information disclosure scheme does not cause leakage of additional private information, and privacy and safety of the information disclosure process are guaranteed.
In the whole process, the block chain ensures that the information in the school which is linked up cannot be tampered, the decentralized identity mechanism ensures the safety and the usability of verifiable statements, the trust chain inside and outside the school is opened, and the fact that whether the information in the school is presented to a user unit or not is determined by the will of the job seeker, so that the block chain has a promoting effect on promoting employment, promoting the trust of the school and the society and ensuring the privacy of the job seeker.
The present specification is described below with reference to specific embodiments and specific application scenarios.
Referring to fig. 2, fig. 2 is a block chain-based job seeker information disclosure method according to an embodiment of the present disclosure, which may include the following steps:
s201, issuing a list of information to be disclosed in a school to a target job seeker by a human unit;
s202, determining whether redundant privacy information except the information to be disclosed in the school information indicated in the list is contained in a first verifiable statement held by the target job seeker; the first verifiable statement is issued by the blockchain and is bound with the decentralized identity, and the blockchain prestores documents with the decentralized identity registered by the target job seeker and a plurality of pieces of on-school information of the target job seeker, which is uploaded by a school office platform and stored;
s203, if not, the target job seeker shows the first verifiable statement to the employing unit, so that the employing unit accesses a distributed account book of the block chain, extracts a signature verification key for verifying the authenticity of the first verifiable statement from a decentralized identity document corresponding to the first verifiable statement, and verifies the authenticity of the first verifiable statement;
and S204, if the authenticity verification is passed, determining that the verification information disclosure process of the target job seeker to the employing unit is completed.
The employment units may include enterprises, individual economic organizations, civil non-enterprise units, national institutions, public institutions, social groups, legal accountants, law firms and other partnerships, foundation and other organizations that desire and provide labor positions to job seekers. It is understood that the above-mentioned labor positions can also be understood in a broad sense, that is, can include various forms such as outsourcing, practice, training, etc.; those skilled in the art can migrate the solution described in this specification to applications according to specific needs.
The job seeker can be a graduate that should be done, or a student who has not been graduate or a social talent who has been graduate, and the description does not limit the type of the job seeker per se.
The school office platform may refer to an office platform of a school corresponding to the information on the school that the job seeker needs to disclose; assuming that Zhang three graduates to AA middle school and BB university, the school office platforms may be referred to as the office platform of AA middle school and the office platform of BB university.
It can be understood that the above-mentioned personnel unit, job seeker and school office platform all refer to roles in the application scene, and when the technical scheme is specifically implemented, the steps executed by each party can be implemented by corresponding computer software and hardware respectively; for example, the aforementioned staff member may use personnel management software to perform the corresponding steps, the job seeker may use job hunting software to perform the corresponding steps, the school office platform may be an online collaboration office platform, and so on. The specific form of the software need not be limited in this specification, and the software may be a conventional x86 executable application running on a desktop computer, a mobile application running on a mobile platform such as IOS and Android, a Web application based on a Web page, or a plug-in or applet embedded in another application. Different application forms can meet different requirements, for example, if the client is realized by adopting a Web application mode, the Web client does not need to be installed generally, and only equipment can normally access a network and render a webpage for execution, so that the convenience of the software can be greatly improved; for another example, if the software is implemented in the form of embedded software bound to hardware such as a specific business teller machine, the stability of the software can be greatly improved and abnormal situations needing to be considered in the operation and maintenance process can be reduced because the operating environment is fixed and safe.
In this specification, the aforementioned employment unit may first issue a list of information to be disclosed at the school to the target job seeker; specifically, the personnel management software of the personnel unit can establish communication with job hunting software of the target job seeker and send the list containing the to-be-disclosed and correction information to the job hunting software of the target job seeker; for example, zhang san is an due graduate of computer profession, who wants to obtain the position of the software development engineer in company XX, and in order to know that zhang san school is in the school, company XX can send zhang san a list containing four items of information to be disclosed in the school, namely "hospital ranking, performance points, reward and punishment information, and scientific research result". It is understood that the above-mentioned manner of communication via the internet is also only an example; in addition, the target job seeker can also acquire the list containing the information to be disclosed in the school by scanning paper recruitment information; the present specification does not need to list all implementation manners, and a person skilled in the art can select a specific channel and a specific manner for issuing the above list.
In this specification, the target job seeker may determine whether a first verifiable statement held by the target job seeker includes redundant private information other than the to-be-disclosed information indicated in the manifest; the first verifiable statement is issued by the blockchain and is bound with the decentralized identity, and the blockchain prestores documents of the decentralized identity registered by the target job seeker and a plurality of pieces of on-school information of the target job seeker, which is uploaded by the school office platform and stored.
The block chain may include any form of block chain. The block chain technology, also called as distributed account book technology, is a technology in which a plurality of computing devices participate in accounting together and maintain a complete distributed database together; in general, blockchains have the characteristics of decentralization, public transparency, participation in database records by each computing device, and rapid data synchronization between computing devices. Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on. In general, various types of blockchain properties may differ, and thus may be used to meet different technical requirements; for example, if the highest degree of decentralization is desired, a public chain may be selected; federation chains, etc., may be selected if desired to compromise decentralization and performance. In implementation, if the blockchain is in a form of a federation chain, the blockchain nodes forming the blockchain can be provided by various entities such as related management departments, common people, enterprises and the like respectively, so as to ensure that the block chain accounting right is relatively fair and reasonable; for another example, if the block chain is in a public chain form of an ether house, a general intelligent contract can be used for constructing related functions, and higher credibility is obtained; it can be seen that various forms of blockchains have advantages, and those skilled in the art can select the type of blockchain according to specific needs, and the description does not limit the specific type of blockchain.
It can be understood that the above block chain may interact with the outside through a block chain as a Service (BaaS) platform. Generally, BaaS platforms can provide flexible and customizable blockchain services to client-side computing devices connected to BaaS platforms by providing pre-written applications for activities that occur on the blockchain (such as subscription and notification, user authentication, database management, and remote updates). For example, in one example, where a target job seeker or human entity needs to communicate data with a blockchain, the BaaS platform may provide a service application such as an MQ (Message Queue); a target job seeker or a person-using unit connected with the BaaS platform can subscribe an intelligent contract deployed on a certain block chain in a block chain system connected with the BaaS platform, and contract events generated on the block chain after triggering execution; and the BaaS platform can monitor the event generated on the block chain after the intelligent contract is triggered to be executed, and then based on software related to MQ service, the contract event is added to the message queue in the form of notification message, so that a target job seeker or a person using unit subscribing the message queue can obtain the notification related to the contract event.
In the art, Decentralized Identity (DID) is generally understood as an Identity authentication mechanism that may contain an Identifier and a document, with global uniqueness, high availability resolvability and cryptographic verifiability. A decentralized identity may be said to be associated with a blockchain if the decentralized identity depends on a blockchain implementation. In implementation, a typical decentralized identity may be represented by the following character string:
did:example:123123123123abcabcabc
wherein, the did part is a system identification for indicating that the character string is a decentralized identity; the example part is a DID method identifier used for indicating the method on the block chain on which DID specifically depends; the 123123123123abcabc part is an identifier specified in the DID method, typically corresponding to a pair of public and private keys held by the individual whose identity corresponds to. The decentralized identity document may include an identity public key corresponding to the DID, a corresponding encryption algorithm, and other information, and may be used to verify the decentralized identity. For example, assuming that a user, zhang san sends a piece of information, which carries a signature of a decentralized identity and a DID identifier, other users can check the validity of the decentralized identity signature only by finding the decentralized identity public key of zhang san from the block chain according to the DID identifier, and if the check is passed, the sender of the information can be proved to be a person who holds the private key of zhang san of the user, that is, zhang san self.
Turning to the disclosure of information described herein, please refer to FIG. 3, FIG. 3 is a diagram illustrating an exemplary checking logic of verifiable claims and checklists; continuing with the aforementioned example of the third Zhang of the computer specialty and the corresponding graduate, assuming that the mother school thereof has stored a plurality of pieces of information at school of Zhang Sanzhong classmates in the block chain, and the block chain has issued a first verifiable statement to Zhang Sanzhong classmates in advance, wherein the first verifiable statement includes 6 verifiable pieces of information at school, including hospital ranking, scientific research results, research and student groups, and further assuming that the software company seeking employment of Zhang Sanzhong classmates gives that the information to be disclosed includes four types of information at school, namely hospital ranking, scientific research results, punishment information and research results, comparing the two types of information, and determining that the first verifiable statement includes redundant private information to be disclosed outside the information at school.
In this specification, if the first verifiable statement held by the target job seeker does not include redundant private information other than the pieces of to-be-disclosed information indicated in the list, the target job seeker may present the first verifiable statement to the human entity; and the user unit can access the distributed account book of the block chain, extract a signature verification key for verifying the authenticity of the first verifiable statement from the decentralized identity document corresponding to the first verifiable statement, and verify the authenticity of the first verifiable statement.
It is generally recognized that in a system of verifiable statements vc (veriable classes), there may be several participants:
issuer (Issuer): the entity that owns the user data and can offer the VC, in the information disclosure scheme provided in this specification, may be a school (or school office) that provides information about the job seeker's college. It is understood that in the information disclosure provided in this specification, the body issuing the verifiable statement after the chain of the parity information may also be the block chain; it may specifically be implemented by intelligent contracts performed on the chain, etc.
Verifier (observer-Verifier, IV): for accepting and verifying a VC, whereby a certain type of service can be provided to the person presenting the VC, the role of which is that of a human entity in the information disclosure scheme provided in this specification.
Holder (Holder): an entity that requests, receives, and holds a VC from an Issuer, also an entity that presents a VC to an IV; in the information disclosure scheme provided in the present specification, the holder is the target job seeker. It will be appreciated that the VC being opened may be placed in a VC wallet for later reuse.
Identifier Registry (Identifier Registry): in the information disclosure scheme provided in this specification, the identifier registration mechanism is the block chain.
Continuing with the example of the third computer specialty symphysis, after receiving the first verifiable statement presented by the third computer specialty symphysis, the job-seeking software company can find the corresponding decentralized identity document from the distributed ledger of the block chain according to the decentralized identity identifier carried by the first verifiable statement, and further extract the signature verification key for verifying the authenticity of the first verifiable statement.
In this specification, if the authenticity check is passed, it may be determined that the first verifiable utterance is made for the checking information uploaded to the blockchain by the blockchain according to the school office system, and the authenticity of the checking information of the target job seeker indicated in the first verifiable statement may be indirectly determined; thus, the completion of the course of disclosing the current school information of the target job seeker to the human unit can be determined.
It will of course be appreciated that the above steps are carried out without the inclusion of redundant private information other than the information to be disclosed in the list, in the first verifiable statement held by the target candidate; if the first verifiable statement held by the target candidate contains redundant private information in addition to the information to be disclosed in the checklist indicated above, the following solutions are also shown in the present specification:
in one embodiment shown, the target job seeker may send the list to the blockchain if the first verifiable statement held by the target job seeker includes redundant private information in addition to the to-be-disclosed, school, information indicated in the list; generating a second verifiable statement containing the to-be-disclosed on-school information indicated in the list based on a plurality of pieces of on-school information of the target job seeker by the blockchain in response to the list, and issuing the second verifiable statement to the target job seeker; then, similar to the aforementioned process of disclosure using the first verifiable statement, the target job seeker presents the second verifiable statement to the human entity, so that the human entity accesses the distributed ledger of the blockchain, extracts a signing key for verifying the authenticity of the second verifiable statement from the decentralized identity document corresponding to the second verifiable statement, and verifies the authenticity of the second verifiable statement; and if the authenticity verification is passed, determining that the target job seeker completes the verification information disclosure process of the human unit.
In the above process, it is essentially a process of requesting a blockchain to open a new verifiable statement for information disclosure in the case where the first verifiable statement already held by the target job seeker does not comply with the privacy protection requirements. Continuing to take the third example of the computer specialty Zhang of the corresponding graduation students as an example, the first verifiable statement held in advance contains 6 verifiable school information including hospital ranking, performance points, reward and punishment information, scientific research results, extrastudy and student groups, and the information list to be disclosed given by a software company seeking employment in Zhang three classmates includes 4 types of hospital ranking, performance points, reward and punishment information and scientific research results, so Zhang three can request a block chain to newly open a second verifiable statement including 4 types of information including hospital ranking, performance points, reward and punishment information and scientific research results, and complete the subsequent information disclosure step by using the second verifiable statement, thereby realizing the protection of the privacy information disclosed by the two types of extrastudy and student groups unnecessarily.
In an embodiment, the method may further include: creating a decentralized identity corresponding to the target job seeker in the block chain, and storing documents of the decentralized identity in a distributed account book of the block chain; and uploading the school information of the target job seeker to the block chain by the school office platform so as to store the school information and the decentralized identity document in a correlation manner.
For example, if li four is a university newborn, the blockchain may create a decentralized identity for it, and store a document of the decentralized identity including identification information such as its name, identification number, public key, and the like in the distributed book of the blockchain, and the office platform of the university of li four uploads the school information of the score, ranking, reward and punishment, and the like of li four to the blockchain during the school of li four, and stores the school information in association with the decentralized identity document.
By applying the scheme, the initialization of new user information can be realized, and further the perfection of the information management and disclosure process based on the block chain and decentralized identity mechanism is realized.
In another illustrated embodiment, to reduce the number of times the verifiable claims are reapplied, reducing pressure on the blockchain network, a proof of residence information combination identification may be used to indicate the combination of the proof of residence information types contained by the verifiable claims; for example, the verifiable statement corresponding to the class a school information combination identifier may refer to a verifiable statement including the hospital ranking and the pure achievement class information of each department performance, and the verifiable statement corresponding to the class b school information combination identifier may refer to a verifiable statement including the class information of the class after school and the student group information, and so on.
When the scheme is implemented, the user unit issues the list of the verification information to be disclosed to the target job seeker, and the verification information combined identifier can be issued to the target job seeker to replace the complete list; when the target job seeker needs to determine whether the first verifiable statement held by the target job seeker contains redundant private information except for the to-be-disclosed school information indicated in the list, the determination can be completed by determining whether the first verifiable statement held by the target job seeker is a verifiable statement matched with the combined identification of the to-be-disclosed school information; if so, the first verifiable statement does not contain redundant private information other than the to-be-disclosed information indicated in the manifest.
For example, if the first verifiable statement held by the student king five at the moment is a class a verifiable statement, and the corresponding group identification of the school information to be disclosed in the school information list proposed by the human unit is also class a, the first verifiable statement of class a held by the human unit can be considered to be directly shown to the human unit, so that the requirement of the human unit on the school information of king five can be met, and no additional information leakage can be caused.
In addition, it can be understood that, as the verifiable statement can be repeatedly used, the target job seeker can quickly find the required verifiable statement by using the verifiable statement identified by the school information combination, and the required verifiable statement does not need to compare the information in each verifiable statement with the information to be disclosed in the school information list issued by the person using unit one by one, so that the system operation efficiency is remarkably improved, the frequency of newly issuing the verifiable statement is reduced, and the processing pressure of the block chain is reduced.
The above description is directed to all embodiments of the method for disclosing information of job seeker based on block chain. Based on the above embodiments, the above scheme can significantly improve the efficiency of completing the whole information disclosure process, and can not cause the leakage of extra privacy information, thereby ensuring the privacy security of the information disclosure process.
The present specification also provides embodiments of a corresponding block chain-based job seeker information disclosure system as follows:

the block chain 403 is used for pre-storing documents for verifying decentralized identities registered by target job seekers and a plurality of pieces of verified on-school information of the target job seekers uploaded by a school office platform;
the employing unit 401 is further configured to, in response to the first verifiable claim presented by the target job seeker, access a distributed ledger of the blockchain, extract a signing key for verifying authenticity of the first verifiable claim from within a de-centralized identity document corresponding to the first verifiable claim, and perform an authenticity check on the first verifiable claim; and if the authenticity verification is passed, determining that the verification information disclosure process of the target job seeker to the employing unit is completed.
It can be understood that the school office platform does not appear as an essential component of the system in the above technical solution, because the school office platform can be an early producer of part of information in the system, but it does not participate in the interaction of the most basic information disclosure process, the system may include the school information uploaded to the block chain by the school office platform, but does not include the school office platform itself.
In one embodiment, the target job seeker is further configured to send the list to the blockchain if the first verifiable claim is held to include redundant private information in addition to the to-be-disclosed information indicated in the list; the blockchain may be further configured to generate, in response to the list, a second verifiable statement including the to-be-disclosed verification information indicated in the list based on a plurality of pieces of verification information of the target job seeker, and issue the second verifiable statement to the target job seeker;
said target job seeker is further operable to present said second verifiable statement to said employing entity;
the human entity may be further configured to access a distributed ledger of the blockchain in response to the second verifiable claim presented by the target job seeker, extract a verification key for verifying the authenticity of the second verifiable claim from the decentralized identity document corresponding to the second verifiable claim, and perform an authenticity verification on the second verifiable claim; and if the authenticity verification is passed, determining that the target job seeker completes the verification information disclosure process of the human unit.
The scheme realizes the supplement of the countermeasure for the situation that the first verifiable statement already held by the target job seeker does not accord with the privacy protection requirement, finally obtains the second verifiable statement opened by the block chain, and completes the information disclosure for ensuring that the privacy is not leaked.
In one embodiment, the blockchain may be further configured to create a decentralized identity corresponding to the target job seeker and deposit documents of the decentralized identity in a distributed book of the blockchain; the system may further include a school office platform for uploading the on-school information of the target job seeker to the block chain, and storing the on-school information in association with the decentralized identity document.
In another illustrated embodiment, the employment unit may be further configured to issue a combined identification of the information of the school to the target job seeker; the verification information combination identifier is used for indicating a verifiable statement containing a combination of the type of the specified verification information; the target job seeker may further be configured to: determining whether the first verifiable statement held by the target job seeker is a verifiable statement matching the at-school information combination identifier; if so, the first verifiable statement does not contain redundant private information other than the to-be-disclosed information indicated in the manifest.
