A Novel Approach to Authenticate Smartphone using Sequence of Multiple Fingerprints within Blockchain Network

In recent times biometric and blockchain are the two main key terms using for security and authentication purpose. In this paper we are proposing a novel approach to ensure the security, integrity, and traceability of sensitive data with integration of fingerprint and sequence ID stored within blockchain network. Without depending on a single authority, the decentralized and unchangeable nature of blockchain provides a strong framework for safely storing and confirming identityrelated data. This work investigates the use of cryptographic hash functions to sequence IDs and fingerprint data representation on the blockchain, preserving user privacy and guaranteeing data integrity with the help of blockchain. It also outlines the possible drawbacks of blockchain, including scalability, high resource consumption, and privacy concerns, in addition to its benefits, which include improved security, tamper-proof records, and transparent data access. Blockchain technology combined with fingerprint and sequence data storage offers a viable solution for high-trust applications including identity management, safe data sharing, and forensic investigations.
