Blockchain for Fraud Prevention: A Work-History Fraud Prevention System

Abstract

Current job recruitment process involves a good number of documentations. It is not uncommon for job applicants to misrepresent, overstate or falsify past employment, specifically work experience, and skills. Where this occurs and the applicant is subsequently appointed, a company may be exposed to significant commercial and legal risk. Companies usually employ third party HR recruitment agencies to verify the authenticity of an applicant's listed work experience. However, verification of applicant's past work experience is both time consuming and costly. Moreover, companies have to rely on the third parties, which may not be trustworthy. Therefore, small and medium size companies usually avoid the verification process. In this research, we demonstrate how blockchain technology can provide cost-effective, and real-time work history verification. The proposed approach also ensures trustworthy and privacy-preserving (work-history) data sharing. Furthermore, we have implemented a prototype to demonstrate how individuals can share and verify work history using Ethereum-based public blockchain.
