CERTIFICATE VALIDATION USING BLOCKCHAIN

Abstract

Blockchain technology can be used to validate certificates by generating digital certificates that are easy to verify and resistant to counterfeiting. In the digital world, each and every thing are digitized in which the academic certificates digitalized in the educational institution and provided to the students. The increase in security breaches compromise user's privacy of academic digital certificate. The institution and organization find it very difficult to validate and verify the digital certificates. By using blockchain technology we can provide a more secure and efficient digital certificate validation. First, generate the electronic file of a paper certificate accompanying other related data into the database,meanwhilecalculatetheelectronicfileforitshashvalue.Finally,store thehashvalueintotheblockinthechainsystem.Itwillprovidethedemandunit to verify the authenticity of the paper certificate through mobilephone scanning orwebsiteinquiries.Throughtheunmodifiablepropertiesoftheblockchain,the system not only enhances the credibility of various paper-based certificates, but also electronically reduces the loss risks of various types of certificates.
