An integrated and distributed biometric-based user authentication architecture

Biometric authentication systems are used to guide the system security for many years in the computer world and make the user's identification easier and more convenient. Meanwhile, the systems encounter lots of challenges, attacks and threats, privacy protection and system management requirements, which affect the user's acceptance. Differing from the commonly used solutions, in this thesis the approach is to modify the system to meet these requirements, which results in a distributed architecture which can be composed in real time, and resolves the above challenges in one solution. A system prototype based on the proposed system architecture is designed as a sample for the reference of other system designers
