Smart Contract for Digital Certificate using Blockchain Technology

The graduation certificate forgery has become a major problem in now a days and the lack of effective anti-forge mechanism, In order to solve the problem of counterfeiting certificates, the digital certificate system based on blockchain technology would be introduced. The system generate the electronic file of a paper certificate accompanying other related data into the database and calculates its hash value. It then store the hash value into the block in the chain system. The system will create a related QR-code and inquiry string code to affix to the paper certificate, this will verify the authenticity of the paper certificate through mobile phone scanning or website inquiries. By integrating the features of blockchain, the system improves the efficiency operations at each stage.
