The traditional system of using and maintaining paper certificates is now facing a threat of forging and modifying the data. This forging of data on the certificates has become a very easy task, which reduces the credibility of paper certificates. Thus, there is a need of an effective anti-forge mechanism to reduce the counterfeiting of certificates. An E-certificate generation and authentication system based on blockchain technology is so proposed. Blockchain provides incorruptible, unmodifiable and encrypted data features. Thus, by using blockchain, an E-certificate with features like anti-counterfeit, anti-forge and verifiability is generated. Students won’t be able to forge the contents of E-certificates at all. The system, because of blockchain technology, will help to solve the problem of fraud certification by enhancing the credibility of the certificates. The system will also save the paper and management costs. Electronically, the loss risks of the certificates will be reduced. In short, the system is all beneficial to us. The working of the system in brief is: A valid electronic file of the certificate i.e. an E-certificate is generated on student’s request. At the same time, that student’s record is stored in the blocks of blockchain by making use of hash values. Along with E-certificate, a related QR code or unique serial number is also provided to the student. And then, the demand unit (e.g. company to which student applied for a job) can check the authenticity of the electronic file using the QR code or unique serial number which is based on the data stored in the blockchain.
