A DECENTRALIZED APPROACH TO ONLINE EXAM RESULT SECURITY USING BLOCKCHAIN

Data breaches and manipulation are making it harder to trust the findings of online tests. This study shows how to use the blockchain's immutability, transparency, and freedom to secure academic data. This method does away with the need for centralized authorities by using smart contracts to automatically store and validate outcomes. This guarantees that the data is untouched and intact. Encrypted results saved in a distributed ledger are only accessible to authorized parties, who may also confirm their veracity. In the end, this technology makes data safer and speeds up credential verification, making academic achievements more reliable and impenetrable.
