Abstract
En 中文
Biometric authentication systems have major security weaknesses: risk of biometric information leakage, unreliability of authentication modules, and non-transparency of biometric information management. This paper presents BDAS, a new biometric authentication system using blockchain, which provides a decentralized and distributed mechanism for processing biometric authentication and an auditable mechanism for managing biometric information. BDAS's evaluation demonstrates that it provides reliable and secure authentication compared to existing methods while introducing negligible performance overhead in real-world scenarios.
