ENHANCING CERTIFICATE SECURITY AND AUTHENTICITY USING BLOCKCHAIN TECHNOLOGY

Abstract

The increasing prevalence of forged academic certificates and fraudulent credentials has become a significant concern for educational institutions, employers, and government organizations. Traditional certificate verification methods are often centralized, time-consuming, and vulnerable to manipulation. Blockchain technology provides a decentralized, transparent, and tamper-resistant mechanism for storing and validating academic credentials. This paper proposes a blockchain-based certificate validation system that enables educational institutions to issue secure digital certificates and allows employers or verification agencies to authenticate them instantly. The proposed system utilizes cryptographic hashing and blockchain technology to ensure certificate integrity and authenticity. By eliminating intermediaries and reducing verification time, the system enhances trust, security, and operational efficiency. The research also analyzes the architecture, methodology, advantages, limitations, and future scope of blockchain-enabled certificate validation systems.
