Description

A SYSTEM AND METHOD FOR CREATING A DATABASE OF INDEPENDENTLY VALIDATED EDUCATIONAL AND WORK EXPERIENCE PROFILES (CURRICULA VITAE) USING BLOCKCHAIN SMART

CONTRACTS

FIELD OF THE INVENTION

The present invention relates in general to blockchain technology, and more particularly, a system and method for creating a database of validated curriculum vitae of educational and work experience profiles (curricula vitae or CVs) of students and experienced hires (candidates) using blockchain smart contracts.

BACKGROUND OF THE INVENTION

A challenge common to most companies seeking talented employees is finding the best set of candidates for the position available. One standard practice among human resources departments is to create a job description for each open position, then advertise the position along with the description. Employer HR/recruiters and candidates then have to review and analyze these descriptions in order to determine a match between candidate's curricula vitae, and particular jobs.

Misrepresentations by candidates of their education, qualifications and work experience within their curriculum vitae (CV) puts employers/recruiters at risk of hiring persons lacking the qualifications and work experience that employers/recruiters were counting on for candidates to be successful and productive in any appointed role. There is a severe problem as regards fraudulent qualifications and employment history, that makes it difficult for a potential employer/ recruiter, to obtain accurate and reliable information about a potential candidate.

Smart contracts are a potentially revolutionary type of application using decentralized ledger networks. The idea underlying smart contracts is that software can automate much of the contracting process. This could allow for the performance, monitoring, and enforcement of contractual promises without human involvement. In the context of this design, the smart contract represents the candidate CV, and approval/agreement by the organizations referenced in the CV.

There is a need to create a reliable database of educational and work experience profiles (CVs) for students and experienced hires that employers/recruiters can rely on when seeking talented employees.

There is also a need to ensure that the ongoing management of the candidate data is placed firmly in the hands of the candidate, and that they have an ability to have the data forgotten if desired.

SUMMARY OF THE INVENTION

It is hence one object of this invention to disclose a computer implemented method of creating a database of curriculum vitae of candidates using blockchain smart contracts, in a private blockchain-based network, the method comprising: electronically creating a smart contract blockchain profile, said profile corresponding to a unique user application facilitating a user interface comprising one or more predefined contract data fields of at least one candidate; said profile including validation of data fields relating to candidates experience/certification by other blockchain participants / organizations (e.g. educational establishments, companies) by digitally signing said fields using their own blockchain private key / account as validation / proof of authenticity of claims in said fields; electronically storing said smart contract blockchain profile in a shared ledger of said database; electronically accessing via user interface said smart contract blockchain profile via said shared ledger of said database; electrically accessing via third party application integration said smart contract blockchain profile via shared ledger of said database; electronically implementing ranking values within said predefined contract data fields of at least one candidate; and electronically scoring said contract blockchain profile of at least one candidate to a specific job posting.

The invention allows organizations referred to in a candidate's profile to electronically sign those entries related to them by using their own blockchain account private keys, thereby validating the candidate's claims recorded in the blockchain smart contract in the distributed ledger, making this available for inspection by other organizations (subject to permission from the candidate who is owner of their profile stored the smart contract).

It is hence another object of this invention to disclose a system for creating a database of curricula vitae (profiles) of job candidates using blockchain smart contracts, in a private blockchain-based network, the system comprising of independent network nodes, each network node comprising: at least one processing unit; a communication or application integration interface communicatively coupled to the processing unit for transmitting and receiving information; at least one data storage device, communicatively coupled to the processing unit, storing a plurality of instructions and data wherein, upon execution of said instructions by the at least one processor, said instructions cause to: electronically create a smart contract blockchain profile, said profile corresponding to a personal curriculum vitae profile comprising one or more predefined contract data fields of at least one candidate, and validation of said fields by other blockchain network participants using their private keys; electronically store said smart contract blockchain profile in a shared ledger of said database; electronically access via user interface or application interface said smart contract blockchain profile via said shared ledger of said database; electronically implement ranking values within said predefined contract data fields of at least one candidate and validation of said fields by other blockchain network participants using their private keys; and electronically score said contract blockchain profile of at least one candidate to a specific job posting.

It is hence another object of this invention to disclose a non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising: electronically create a smart contract blockchain profile, said profile corresponding to a unique user application facilitating a user interface comprising one or more predefined contract data fields of at least one candidate; electronically store said smart contract blockchain profile in a shared ledger of said database; electronically access via user interface said smart contract blockchain profile via said shared ledger of said database; electronically implement ranking values within said predefined contract data fields of at least one candidate; and electronically score said contract blockchain profile of at least one candidate to a specific job posting.

The candidate profile smart contract includes permission logic, such that the candidate, using their private key, can set the visibility permission of the smart contract through encryption of the data items (off chain). Only blockchain accounts with a corresponding private keys are able to decrypt (off chain) the candidate profile data stored in the smart contract. The smart contract code will also control who can modify the data items, such that only the candidate can change their profile, and only organizations referenced in the profile can approve the assertions regarding educational certifications or work placements. The right for a candidate to have their data (on chain) forgotten is of paramount importance. The method by which a candidate profile smart contract stores data, and the method by which that data is read by the user, and validating organisation, will enable data relationships to be redacted, and, therefore, allow for an individual's data to be forgotten.

The terms "redacted" or "redacting" refer to selecting, editing or adapting (as by obscuring or removing sensitive information) for publication or release; to obscure or remove (text) from a document prior to publication or release. This is done to support the candidates right to have at least portions of their data forgotten ,

THE INVENTION The present invention utilizes blockchain smart contracts technology to create a reliable database of candidate profiles including validated records of their certificates of education and work experience. The private blockchain network connects different organizations (with their own copy of the private blockchain ledger) such as educational establishments, companies, and government organizations) and acts as a shared database. Each candidate has a smart contract in the shared ledger. The smart contract acts as a shared record of the candidate profile. Smart contract of a candidate may include (but not be limited to) the following data fields:

Name

- Address

- Date of Birth

- Gender

Nationality (work permit, etc.)

Academic Achievements:

o Educational Establishment

o Certification Level

o Grade

o Subject

Employment

o Employer

o Period

o Role

o Direct reports

o Budget Responsibility

o Skills

Government Identifiers

Right to Work permits

Psychometric Profile

- Health Profile

Financial Profile Each component (e.g. Academic Achievements, Employment) are potentially verifiable. Every change to a candidate's profile is added by sending a transaction to the blockchain. Every change is therefore recorded in the immutable history in the ledger and signed by the private key of the blockchain account that sent the transaction. When a change is made through a blockchain transaction, the relevant parties are notified using a blockchain event; for example, when an organization updates a candidate profile, the candidate is notified.

For organizations such as educational establishments / employers / companies / accrediting organisations, the present invention may integrate with their internal HR/performance management systems (e.g. PeopleSoft HR, SAP HR, Oracle Taleo, etc.), such that validation of the candidate certificates of education or record of work experience may be automated, and as an efficient means of updating the candidate's profile. For educational institutions the present invention may integrate with their student management systems (e.g. Eduware, Ellucian, Jenzabar, Skyward, SunGard), again, as an efficient means of updating the educational profile of a candidate. In this case, the application server connected to the local blockchain node belonging to the organization will execute the validation request from the candidate profile blockchain smart contract profile by calling the internal system, and confirm (or reject) the request by submitting a transaction using the organization's private key to the candidate profile blockchain smart contract. The present invention also includes a search and match facility, such that the validated database of candidate profiles can be interrogated for candidate profiles that match employer requirements. This capability includes analytics and machine learning algorithms in the employer application that is connected to their blockchain node to provide the best match results. The candidate application (attached to the candidates blockchain node) will also include a facility to upload candidate profiles in various formats, parse those formats and store them in a standard structure with a standard taxonomy in the blockchain smart contract. DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

Reference is made now to FIG.l. which shows an example of the process flow 100 using an embodiment of the invention. The use case is related to creating a database of curriculum vitae of job candidates using blockchain smart contracts. The following steps are performed: a candidate electronically creates a smart contract blockchain profile via designated GUI 102 via Application C, said profile corresponding to his/her personal curriculum vitae 128 comprising one or more predefined contract data fields of the candidate, including assertions regarding educational certification at Educational Institution and an employment engagement at Employer Institution; the smart contract blockchain profile is then electronically stored in a shared ledger of said database 104.

Employer Institution, and/or Educational Institution, receives a notification to approve the educational certification and/or work experience in the candidate profile assertion. The notification for approval is received via the blockchain in the form of a blockchain smart contract event. Application A is notified by Educational Institution's blockchain node, which in turn prompts for manual approval via the UI or via integration with their internal educational management databases 114. Once approval is made it is sent as a blockchain transaction the candidate profile smart contract through the Educational Institution blockchain node and stored within said shared ledger 120 of said database, can be electronically accessible and referenced via user interface of said smart contract blockchain profile implemented within their internal educational management databases 114 via said shared ledger of said database; and/or generated by the candidate profile can be electronically accessible and referenced via user interface of said smart contract blockchain profile implemented within their internal HR databases 110 via said shared ledger of said database and notify the candidate of potential interest 126.

The candidate profile stored in said database is interconnected and can be modified in realtime by a signature of a generated private key within the smart contract blockchain profile and updated across all the organizations that have an access to said smart contract blockchain profile 106 108 122 124.

As a non-limiting example, the profile creation of the candidate party in a transaction can be executed using a computerized process according to the example method 200 illustrated in FIG. 2. As illustrated in FIG. 2, the method 200 can first receive a request for any new candidate profile generation accessible via GUI 204. The system then electronically generates a smart contract blockchain profile, said profile corresponding to a unique user application facilitating a user interface comprising one or more predefined contract data fields of at least one candidate 208, said profile is confirmed via smart contract blockchain mechanism 210. Said profile corresponding to a unique user application facilitating a user interface comprising one or more predefined contract data fields of at least one candidate, the modification of said data fields is confirmed in real-time by a signature of a generated private key within said smart contract blockchain profile 206 212. The candidate profile stored in said database is interconnected, can be modified in real-time and updated across all the organizations that have an access to said smart contract blockchain profile 214.

As a non-limiting example, the profile confirmation of the organizational party in a transaction can be executed using a computerized process according to the example method 200 illustrated in FIG. 3. As illustrated in FIG. 3, the method 300 can first receive an application request from a candidate seeking a job listing 304. The electronically generated a smart contract blockchain profile, corresponding to a unique user application facilitating a user interface comprising one or more predefined contract data fields of at least one candidate, can be validated via smart contract blockchain mechanism 306 308.

Reference is made now to FIG. 3 which graphically illustrates, according to another preferred embodiment of the present invention, an example of computerized system for implementing the invention 300. The systems and methods described herein can be implemented in software or hardware or any combination thereof. The systems and methods described herein can be implemented using one or more computing devices which may or may not be physically or logically separate from each other. Additionally, various aspects of the methods described herein may be combined or merged into other functions.

Reference is now made to FIG 5. FIG 5 shows an example of the process flow 500, using an embodiment of the invention. As a non-limiting example, the use case is related to recording the details of a candidate in the database of curriculum vitaes using blockchain smart contracts that can be requested to be forgotten (redacted) by the candidate. The following steps are performed: a candidate electronically requests a validation of candidate profile data 503 and for that validation to be recorded against the smart contract blockchain profile by an individual or organisation. On the request to validate being granted 512 by the individual or organisation, the validation is recorded on a mutable datastore 505 506. The candidate is then asked if they would like the record of the validation to be related to their candidate contract smart contract 513. On acceptance the record of validation is written 514 to the smart contract on the blockchain 507 508 509 510. Only the candidate can read the assertion 507 on their smart contract candidate profile and the relationship 508 between that assertion and the validation 510. The relationship 505 between the assertion 503 and the validation 506, as well as the representation of that validation 510 and the hash of the relationship 509 is open for any individual to see.

If the individual wishes for their data to be forgotten. The key 501 on their mobile device needs to be deleted, which, in turn, will flag their candidate profile (on and off chain) to be forgotten. They will be asked through another digital means as to whether their candidate profile data 503 will be deleted, and, on validation of that request, their candidate profile data 503 will be deleted.

All data 503 505 506 associated with the user would be deleted in the mutable datastore. Given that the user has deleted the private key on their mobile, the candidate profile 507 and hash of the DL relationship 508 will no longer be able to be read, and therefore redacted.

In some embodiments, the illustrated system elements could be combined into a single hardware device or separated into multiple hardware devices. If multiple hardware devices are used, the hardware devices could be physically located proximate to or remotely from each other.

The methods can be implemented in a computer program product accessible from a computer-usable or computer-readable storage medium that provides program code for use by or in connection with a computer or any instruction execution system.
