Blockchain-based system for Secure Document Verification using QR codes

Employers now face significant difficulties in con- firming educational credentials in today’s competitive labor mar- ket, especially when hiring a large number of recent graduates. Businesses are frequently burdened with expensive and time- consuming procedures to verify the legitimacy of credentials like degrees and transcripts. A more effective, secure, and trustworthy method of confirming academic credentials is becoming more and more necessary as fake certificates become more common. In order to counter the spread of phony credentials, this paper promotes the creation of a blockchain-enabled digital certificate verification system. Digital certificates will be created by the system and stored in a blockchain-based setting, offering a decentralized, transparent, and impenetrable verification pro- cess.Employers, educational institutions, and other stakeholders will be able to verify each certificate in real time thanks to its secure blockchain storage and dynamic QR code identification. The suggested remedy entails building a unique blockchain on an open-source platform with a customized mining approach to improve security and performance. Controlled updates will be made possible by smart contracts, enabling authorized parties to make required modifications while maintaining the integrity of the blockchain. This dynamic approach guarantees that educa- tional records can be updated without jeopardizing the security or legitimacy of certificates that have already been issued. This system will drastically cut down on the time, effort, and expenses associated with conventional verification techniques by utilizing blockchain’s immutability and decentralization.It also provides businesses and educational institutions with a scalable solution that expedites the verification process and increases confidence in the legitimacy of educational records.
