A Blockchain-based Document Verification Model in Freshers Hiring Process

A quick growth of information sharing and transferring has been observed recently. Everything is getting digitized, and everyone requires a simple and straightforward method. As a result, the number of fake documents generated for job applications is increasing, and checking all the documents manually is not a good option as it takes a lot of time. Therefore, digitizing documents is becoming an increasingly popular option for companies and individuals as it is the most secure and least time-consuming way of verifying documents. As Blockchain is a decentralized system that guarantees the protection of data kept in it, this article proposes a solution based on Federated Blockchain technology that allows specific organizations to submit candidates' original documents. It validates the student's submitted document hash value by comparing the existing cryptographic hash in the Blockchain. SHA-512 is used to generate the hash values for the documents. This technique is incredibly efficient, consumes less time, and is less expensive to execute all types of verifications.
