A New Decentralized Certification Verification Privacy Control Protocol

Academic Certificates are a social convention that offers a forum for new knowledge about a person or an entity to be transmitted. Academic certificates are one of the areas of education in which the short-term application of blockchain technology can be seen. The practice of certificate fraud is common, undermining investment and trust in higher education systems and bearing substantial economic and social. Falsified qualifications vary from diplomas in high school to doctoral degrees. In addition, the credentials of several famous universities have been forged and it is very difficult to detect such forgeries. Hence, blockchain was introduced to improve the verification process of academic certificates. Recently, blockchain technology has emerged as a potential way of authenticating the process of document authentication and as an effective tool for combating document fraud and misuse. Blockchain based applications have been developed by various Universities. However, privacy preserving was a challenge in most of the existing solutions. Privacy indicates that the certificate protects both identity and information. Therefore , a new Decentralized Certification Verification Privacy Control Protocol is proposed. The proposed protocol can be used for issuing and verifying educational certificates while maintaining privacy and confidentiality at the network level (Ministries level, Universities level, Students level) and data level. The decentralized solution was implemented using Hyperledger Fabric as the infrastructure and Javascript as the contract language.
