An Intelligent Access Control System Based on Multi-biometrics of Finger

摘要

To address limitations of existing biometric access control systems in "smart" living environments, we introduce the design and construction of an intelligent access control system based on multi-biometrics of the finger. We formulate our system on three aspects: hardware structures, feature extraction and matching algorithm design, and software framework. By taking advantage of the high uniqueness of fingerprints and the strong anti-counterfeiting performance of finger veins, the system has considerable improvement in security and accuracy. In addition, it enables a security solution with a combination of pyro-electric sensor, voice message, video intercom, and the burglar alarm, etc. The experimental results show that the equal error rate is 0.27% and the time consumption of authentication is about one second, which demonstrates that our system meets the requirements of an access control system.
