Next Generation Digital Certificate Validation - Leveraging Blockchain for Security and Efficiency

Fake certificates have always been a menace in sectors such as education, professional affiliations, and in legal documents. However, there are so many drive-in graduation certificates because the anti-forging measures are not sound. Universities provide educational certificates, which are essential documents. A blockchain based digital certificate system is presented to eradicating counterfeit certificates. Blockchain is a distributed ledger technology that revolutionized certificate verification, authentication, and fraud prevention with the advent of blockchain-based digital certificates. The innate features of blockchain technology such as immutability, transparency and decentralization enable storing of the digital certificate data on a ledger of blockchain. Each certificate is represented as a separate token on the blockchain, making sure that it is real. The design takes care of both the issues: the decentralized nature helps reduce breaches and unauthorized access to data, while the cryptographic nature ensures that data is encrypted. In this paper, we define the implementation of validations for a blockchain based digital certificates. The methodology provides hash value using SHA-256 and then it compares hash value with blockchain hash. Our approach is leans on smart contracts and our own encryption method to construct a blockchain based scoped credit validation system.
