The Aadhaar system, being one of the world's largest biometric identification systems, faces numerous challenges related to data security, privacy, and centralized control. These concerns have prompted the exploration of decentralized technologies such as blockchain, which offer improved transparency, security, and immutability. This paper explores the integration of blockchain technology with the Aadhaar database to create a more robust, tamper-resistant, and secure identification system. We propose a blockchain-based Aadhaar framework that ensures data integrity, minimizes unauthorized access, and enhances user control over personal data. The paper also discusses the potential challenges and opportunities presented by blockchain integration and suggests implementation strategies to balance efficiency, scalability, and security. Key Words: Aadhaar, blockchain, biometric data, security, decentralization, privacy, data integrity.
