Certificate Generation and Verification System Using Blockchain Technology and Quick Response Code

The number of certificate counterfeits in our society has become challenging and prevalent. Today, forging certificates has become a business tumbling from the need/want of the people for employment. Graduates with legitimate certificates/degrees are denied job opportunities by the holders of these forged credentials. To address this problem, many researchers have proposed a certificate verification system. Although the existing systems can solve some of the major problems such as accessing student’s records with the provision of a central database to manage these records electronically. However, the system can easily be hacked and manipulated since it is mostly available on centralized servers. This dissertation developed a certificate generation and verification system using blockchain technology and Quick Response (QR) code. Iterative and incremental models were used for the system modelling. Also, Data flow diagrams and use case scenarios are used to demonstrate the functionality of the web application. Consequently, suitable programming languages were chosen to implement the proposed algorithm of the system. Hypertext Preprocessor Pages (PHP) and Spring boot (Java framework) were used for the implementation of frontend and backend respectively. The system was evaluated and show that not only is secure but also protects the student’s identity by providing an anonymous verification setting.
