EDUCATIONAL CERTIFICATE VERIFICATION SYSTEM USING BLOCK CHAIN

Abstract

In this project to secure academic certificate and for accurate management and to avoid forge certificate we are converting all certificates into digital signatures and these digital signatures will be stored in Block chain server as this Block chain server support tamper proof data storage and nobody can hack or alter its data and if by a chance if its data alter then verification get failed at next block storage and user may get intimation about data alter. In Block chain technology same transaction data stored at multiple server with hash code verification and if data alter at one server then it will be detected from other server as for same data hash code will get different. For example, in Block chain technology data will be stored at multiple servers and if malicious users alter data at one server then its hash code will get changed in one server and other servers left unchanged and this changed hash code will be detected at verification time and future malicious user changes can be prevented. In Block chain each data will be stored by verifying old hash codes and if old hash codes remain unchanged then data will be considered as original and unchanged and then new transaction data will be appended to Block chain as new block. For each new data storage all blocks hash code will be verified.
