According to the Indian Ministry of Education statistics, document verification is a complex domain that involves various challenging and tedious processes to authenticate. Due to the lack of an effective anti-forge mechanism, events that cause the graduation certificate to be forged often get noticed.In order to solve the problem of counterfeiting certificates, the digital certificate system based on blockchain technology would be proposed. For students, educational certificates are the most important documents issued by their universities. However, as the issuing process is not that transparent and verifiable, fake certificates can be easily created. A skillful generated fake certificate is always hard to detect and can be treated as the original. With the increase of forged documents, the credibility of both the document holder and the issuing authority is jeopardized. In order to solve the problem of counterfeiting certificates,the digital certificate system based on blockchain technology would be proposed. By the modifiable property of blockchain, the digital certificate with anti-counterfeit and verifiability could be made. The procedure of issuing the digital certificate a in this system is as follows. First, generate the electronic file of a paper certificate accompanying other related data into the database, meanwhile, calculate the electronic file for its hash value. Finally, store the hash value into the block in the chain system. In this research, the authors have identified the security themes required for document verification in the blockchain.This research also identifies the gaps and loopholes in the current blockchain-based educational certificate verification. The system will create a related QR-code and inquiry string code to affix to the paper certificate. It will provide the demand unit to verify the authenticity of the paper certificate through mobile phone scanning or website inquiries.
