An Automated Certificate Validation System Using Blockchain Technology for the Hiring Process

Blockchain is a digital, distributed and decentralized database that allows multiple users to store immutable transactions. The core structure of the blockchain contains a group of blocks in which every block can have a set of transactions. These sets of blocks are linked together by generating cryptographic hashes, which makes the data present in blocks immutable. The central authority is not required to manage data stored in the blockchain. A few prominent features of blockchain include Decentralization, Transparency, Security, Immutability and smart contracts. These key features made the blockchain popular in many domains. In this work, Blockchain is used as a secured database to store the academic certificates of students to streamline certificate validation in the hiring process. In the hiring process, validation of authenticity and certificates of students becomes time-consuming and difficult tasks for employers. Blockchain leverage can make this task easier. The universities can upload the E-certificates of graduating students to a blockchain, which will generate a digital transcript for each student. The generated digital transcript has to be communicated to respective students. Whenever the student applies for a job, the employer can validate the student's certificate by comparing the digital transcript received from a student with the certificates stored in the blockchain. If there is a match, it indicates that the certificates are authentic.
