Digital Assurance and Traceability of NFT-based Certificates
Abstract
With the development of technology in today's world, many sectors are conducting their activities in digital environments. This development strengthens the connection between users and the industry, and more efficient results are obtained. However, along with many advantages of digitization, there are also problems such as security loss, copyright infringement, and data corruption. The ease of replicating and distributing data on the internet is due to various security vulnerabilities. This study proposes a solution for protecting certificates issued to individuals by companies/institutions in the digital environment, following a certain degree of success. Certificates are used for job applications, competency verification, and similar purposes. Currently, fake certificates and diplomas produced create problems for institutions and organizations that verify competencies. In this respect, it is possible for people without the required skills to take unwanted positions. This study aims to prevent fake certificates and propose a system that enables certificate holders and institutions to verify certificates. Additionally, it is aimed to make certificates traceable and provable in digital environments. The proposed method aims to create certificates using blockchain technology through smart contracts and to make them available to users on a website. Furthermore, it is suggested to use NFTs, another technology offered by blockchain, to provide intellectual property rights to certificates, enabling them to be monitored and owned on the internet.
