Description

Personnel recruitment system using smart contract function in blockchain environment {Smart Contract based Personnel Recruitment System in Block Chain}

The present invention relates to a personnel recruitment system that utilizes a smart contract function in a blockchain environment, and more particularly, through the introduction of a blockchain-based personnel recruitment system, the source of transparency, security, and post-manipulation possibility in major stages of recruitment is systematically blocked. Thus, it is related to a personnel recruitment system using smart contract functions in a blockchain environment to secure the reliability of public institutions.

In general, job seekers directly research job advertisements in various publications, attend government or industry employment offices or job fairs, or send a series of unsolicited resumes to prospective employers.

In addition, for certain positions, specifically skilled, technical, and management-related positions, seek assistance from career counselors, employment officials, and employment agencies.

And, in the online recruitment process using the Internet, the job seeker first registers personal history information by accessing the homepage of the job seeker or the job search service provider server, and the job seeker examines the registered personal history information and selects the applicants who passed the document screening. , It is common to notify the successful candidates of each document screening on the matters related to the interview, and to select and notify the final candidates based on the evaluation of the interview.

The existing hiring system has a problem that the scorer's evaluation score is integrated and stored in a centralized server, so that the scoring result may be manipulated and changed by an external hacker, and the content of the recruitment notice cannot be arbitrarily changed. There was a problem that there was a lack of a third-party proof function, such as confirmation of application documents received by a third party of the job applicant.

Republic of Korea Patent Application Publication No. 10-2003-0070203

The present invention was conceived to solve the above-described problems, and a system that can be trusted mutually between a job applicant and a company recruitment system (a system that manages document recipients, written tests, interviews, etc.) using a smart contract, which is the core of blockchain technology. In other words, a smart contract between the applicant and the recruiting company through the blockchain smart contract in advance can be made to prevent the act of arbitrarily or maliciously changing the recruitment conditions after the recruitment agency presents specific conditions in the recruitment announcement. It is to provide a personnel recruitment system that utilizes the smart contract function in a blockchain environment that ensures that the contract is maintained and automatically notifies the job applicant when the job posting is changed, so that the content of the job posting cannot be arbitrarily changed/manipulated.

In order to achieve the above object, the personnel recruitment system using the smart contract function in the blockchain environment of the present invention, when the recruitment information is registered in the recruitment system through the recruiter terminal, the recruitment information is stored in a blockchain and then all nodes participating Distributed and stored in their blockchain; When a job application document according to the job application information is received to the job system through the job applicant terminal, a blockchain smart contract is created based on the job information, job information, and applicant information; Various evaluation scores for job applicants entered into the recruitment system through the grader terminal are characterized in that a block is created and stored after the grader information and the grade point are registered together in recruitment information, recruitment information, and job applicant information.

Through the blockchain smart contract, it is possible to keep the smart contract conclusion between the job applicant and the recruiting company, and automatically notify the job applicant when the job information is changed.

When inputting various items according to the employment information to the recruitment system through the job applicant terminal, a receipt according to the job application may be automatically issued to the job applicant terminal when a predefined input condition is satisfied.

The results of the screening of documents entered through the scorer's terminal can be stored in the blockchain and then distributed and stored in the blockchain of a plurality of participating nodes.

The scoring results for the written test entered through the scorer's terminal can be stored together in the blockchain to verify and verify the input data and the scoring results, and then distributedly stored in the blockchain of a plurality of participating nodes.

The scoring result for the interview screening input through the scorer terminal may be directly input and recorded at the place where the interview is conducted.

According to the personnel recruitment system using the smart contract function in the blockchain environment of the present invention as described above, the recruitment applicant and the company recruitment system (document recipients, written tests, interviews, etc.) using smart contracts, which are the core of the blockchain technology. It is possible to create a mutually reliable system between management systems), and to prevent the act of arbitrarily or maliciously changing the recruitment conditions after the recruitment agency presents specific conditions in the recruitment announcement, that is, blockchain smart in advance. It has the effect of keeping the smart contract conclusion between the applicant and the recruiting company through the contract, and automatically notifying the job applicant when the job posting is changed, so that the contents of the job posting cannot be arbitrarily changed/manipulated.

2 is a diagram showing a storage process in the current personnel hiring system,
3 is a diagram showing a storage process of a personnel recruitment system using a smart contract function in a blockchain environment according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to describe in detail so that those skilled in the art can easily implement the present invention.

First, since a number of irregularities in hiring by public institutions were recently discovered, it was necessary to improve fairness and transparency in the hiring process.Through the introduction of the blockchain-based personnel hiring system according to the present invention, transparency, security, and post-manipulation at major stages of hiring were systematically It is possible to secure the reliability of public institutions by blocking the source.

The present invention uses a smart contract, which is the core of blockchain technology, to create a mutually reliable system between a job applicant and a company recruitment system (a system that manages document recipients, exams, interviews, etc.).

In addition, the recruitment agency presents specific conditions in the recruitment announcement (recruitment information) and changes the recruitment conditions arbitrarily or maliciously afterwards (e.g., to consider a specific person (for the first time)'Language score of 700 or more' → (Change ) It is also possible to prevent the act of mitigating to'more than 600 language credits').

In other words, it is impossible to arbitrarily change and manipulate the contents of the job posting by maintaining the smart contract agreement between the job applicant and the recruiting company in advance through the blockchain smart contract, and automatically notifying the job applicant when the job posting is changed.

As shown in Fig. 1, the hiring process in the personnel hiring system using the smart contract function according to the present invention can be largely divided into hiring announcement, document screening, written test, and interview screening.

For the recruitment announcement, the recruitment officer posts recruitment information such as recruitment conditions, deadlines, and input items in the recruitment system in the form of a notice, and this recruitment notice is stored in a blockchain so that the contents cannot be manipulated after the notice.

In other words, when the hiring manager registers the hiring information in the hiring system, the conditions of the hiring announcement are input and stored in a smart contract to prevent any change of the content and conditions of the initial hiring announcement such as deadline and hiring conditions. The content is distributed and stored in the blockchain of all participating nodes.

However, if there is a legitimate reason such as correction announcement/re-announcement/cancellation of announcement, it can be made as an exception if the reason and conditions meet the prerequisites for the job announcement.It is automatically reflected in the smart contract block, and only when the pre-designated conditions are met Correction announcement/re-announcement/cancellation of announcement is possible, and it is configured to be automatically sent to job applicants when a job announcement is changed or manipulated.

Therefore, it is possible to prevent the act of arbitrarily modifying and changing the contents of the employment announcement without following the normal procedures such as correction announcement and re-announcement of the initial recruitment announcement.

When applying for a job through the terminal, a smart contract of [Recruitment Officer Information] + [Recruitment Information] + [Recruitment Applicant Information] is concluded, and accordingly, the completion of the application for job application is objectively verified and guaranteed. The act of disqualifying after hiring companies for'not accepted' is prevented.

In other words, if the job applicant enters the documents for job application and the input items for job posting normally without omissions or errors, the recruitment system uses the smart contract function to send the job applicant a confirmation of inputting the job application documents to apply. It is possible to secure objective evidence regarding whether or not.

All logs (records) related to the job application entered in the recruitment system can be viewed by job applicants and blockchain participants through a private key.

Document screening is pre-defined in the recruitment system by applying the Smart Contract function when the job applicant enters various items required in the recruitment announcement using terminals such as PC, smartphone, tablet PC, etc. When input conditions (for example, deadline, input items, application qualifications, etc.) are satisfied and entered by the job applicant, a receipt is automatically issued to the job applicant's terminal.

This receipt will have public confidence and will secure public confidence whether or not the application has been successfully completed on time.

In addition, a verified block is added to the existing blockchain to prevent post-manipulation of the screening evaluation results of the primary document reviewer, and distributed management to numerous nodes (at least 100 nodes) participating in this Even if is hacked or forged, the rest of the nodes retain the original, so it is configured so that manipulation of the document screening score is impossible (e.g., 51% or more nodes can only be forged/modified when manipulated due to simultaneous hacking damage within a very short time. It is virtually impossible.)

Written exams are usually conducted offline, but scoring results are entered online again, and in this process, there is a possibility of deliberate manipulation of scores.

Therefore, the input data and the scoring result are stored together in a blockchain to verify and verify the scoring results, and distributed records are recorded in the distributed ledger of at least 100 nodes so that forgery/modification is impossible even when hacking from outside occurs.

Interview screening is configured to prevent post-score manipulation that may occur during handwriting by inputting the results of interview scoring directly at the interview using mobile terminal devices (Galaxy Tap, iPad, etc.).

In addition, the mobile terminal device is equipped with a fingerprint recognition device so that only the first designated interviewee can participate in the interview through an authentication process using fingerprint recognition, etc., and the authentication result, GPS coordinates of the interview location, time, etc. It is possible to save and participate in the interview as a proxy, or to block the act of receiving a separate signature of only the interviewer's false confirmation form in another area.

Therefore, even if some data is forged/modified by distributing and storing data of the hiring process including document screening, written test, and interview, the confidentiality of the data can be protected because it is impossible to forge/modify the entire data by hacking at the same time.

Next, various evaluation scores, such as document screening score, written test score, and interview application, are blocked by registering [Scorer Information] + [Scoring Score] in [Recruiter Information] + [Recruitment Information] + [Applicant Information] information. And store it in a blockchain.

In other words, various quantified scores, such as document screening scores, written test scores, and interview acceptance, etc., are distributed and stored in blocks and stored individually in more than 100 nodes, and each node verifies the block contents and, if there is no abnormality, the corresponding block is saved. It is configured to prevent post-manipulation by connecting to the block in a chain method.

In addition, various quantified scores, such as document screening scores, written test scores, and interview acceptance, are distributed and stored so as not to be forged or altered, and at the same time, original data that serves as the basis for the quantitative score (document screening evidence (graduation certificate, certification, transcript) , Language scores, etc.)) are permanently stored in a distributed node as a block so that post-verification is possible.

For the purpose of verifying the identity of the interviewer for future interview screening and objective proof of the interview location, the result of identity authentication through fingerprint recognition information, GPS coordinates of the fingerprint-authenticated terminal device, and interview participation time are permanently stored in a block for post-verification. It is organized so that the first designated interviewer can confirm that he has participated in the actual interview at a proper place.

Therefore, the final data is [Recruiter Information] + [Recruitment Information] + [Applicant Information] + {[Scorer Information] + [Scoring Score]} + [Confirmation Final Results Information] is stored in the blockchain, and recruitment procedure The smart contract function is used to automatically notify the job applicant at a predetermined time after inputting whether or not the applicant meets the criteria.

Subsequently, when the smart contract conditions (support personnel, expiration of period, etc.) are satisfied, the contract (recruitment announcement) is automatically terminated.

The personnel recruitment system using the smart contract function according to the present invention configured as described above adopts a distributed storage method rather than the centralized method shown in FIG. 2, so that it is possible to operate more safely from hacking damage.

Therefore, as shown in Fig. 3, a smart contract-based contract is concluded between the recruiting company and the job applicant, and when the content of the job announcement is changed/manipulated, the program is embedded in the smart contract so that an automatic email is sent to the job applicant. You can block the possibility of.

In addition, the scoring results of the document screening, written test, and interview are safely distributed and stored in blocks every second, so that even the hiring manager cannot manipulate it.

By using smart contract technology, it is possible to objectively verify the applicant's application, and since post-score manipulation is impossible, it can be recognized as a reliable system from a third party.

By operating a plurality of nodes, the node creates a block, and the remaining nodes are configured to identify whether the block is normal, and each block is connected to a chain, so that even if the block in which the previous scoring result is stored is manipulated, all blocks connected after it are manipulated. Since all must be changed, it is almost impossible to forge/modulate all nodes at once with a lot of computing power and simultaneously for a short period of time.

According to the personnel recruitment system using the smart contract function in the blockchain environment of the present invention as described above, the recruitment applicant and the company recruitment system (document recipients, written tests, interviews, etc.) using smart contracts, which are the core of the blockchain technology. It is possible to create a mutually reliable system between management systems), and to prevent the act of arbitrarily or maliciously changing the recruitment conditions after the recruitment agency presents specific conditions in the recruitment announcement, that is, blockchain smart in advance. It has the effect of keeping the smart contract conclusion between the applicant and the recruiting company through the contract, and automatically notifying the job applicant when the job posting is changed, so that the contents of the job posting cannot be arbitrarily changed/manipulated.

In the above description, preferred embodiments of the present invention have been presented and described, but the present invention is not necessarily limited thereto, and those of ordinary skill in the technical field to which the present invention pertains within the scope not departing from the technical spirit of the present invention. It will be readily appreciated that many substitutions, modifications and changes can be made.
