A Model for Securing Institutional Data Using Blockchain Technology

Abstract

Educational institutions store their valuable data in registers where it can be exposed for tampering. We can store those transactions such as attendance, marks and certificates and secure them using a blockchain and can be viewed by anyone in the institution. Traditional methods of record keeping like storing marks in a register or a physical ledger are not secured. An instructor or a student may allegedly change the data for their own selfish needs which are unethical in educational field. Blockchain has a decentralized architecture which stores and secures transactions transparently, and there will be no central authority over those occurring transactions. Therefore, a novel model is proposed in smart contracts which secures and stores each transaction in a blockchain with hashing algorithm making them tamperproof.
