Currently, the job recruitment process takes a lot of process steps and needs several applicant documents. It is very well known for job applicants to exaggerated, misrepresent, or falsify their work experiences, skills, performances, and other past employment data histories. The effect of falsifying data of job applicants may put a company at legal risk and significant commercial losses. Generally, companies as a recruiter use third-party Human Resources recruitment agencies to dealing with the process of verifying job applicant’s employment history by checking and confirming job applicants’ work history experience letter. However, involving third-party (HR) recruitment agencies is time-consuming and costly which may not convenient for all companies, especially for small companies. Additionally, it makes companies depend too much on third-party agencies which may not trustworthy and cause several other risks. Many companies use experience letters as proof of work history documents of their employee. However, the process of publishing an experience letter may involve unfair judgement and may contain conflict of interest between company and employee. Yet, publishing an experience letter is not mandatory for former companies in several countries and regions as it is not under their Government regulation. In this research, we propose a system to verify past employment data histories by using performance appraisal as proof of work history and utilizing Blockchain to provide a cost-effective, secure system, tampered-proof and real-time work history verification. The proposed approach also able to minimizes trust issues and privacy of data sharing by adding several encrypt and digital signature schema using Elliptic Curve Cryptography (ECC) algorithm. Furthermore, we have implemented a prototype to demonstrate how the proposed system work using a Quorum-based consortium blockchain
