Abstract
Biometrics of human begins are widely used as personal identification in order to substitute for the defects of passwords, personal identification numbers, credit cards, keys, …etc. The use of biometrics on security systems enjoys the superiority of high security. Among all biometric features, fingerprint verification is the most reliable technology. The procedures of a fingerprint identification system can be divided into three stages that are fingerprint capture, image pre-processing and feature matching. The performance of a fingerprint identification system may be influenced by the procedures of each stage. In the past, infrared technology was merely used on military applications. Recently, applications of infrared technology are extended to other areas such as data communications and medical applications. Infrared data communications enjoy much merit of the high data privacy, low complexity and low cost over RF. Till now, the widespread use of infrared technology on computer, communications and consumer electronic products provide users with tools for universal connectivity. Therefore, we design and develop a wireless fingerprint identification and authentication system through the combination of fingerprint verification and infrared data communication technology. And we aim at the wireless communication of our system to propose some requirements for transmission speeds, capabilities of data link control, multiplexing, …etc. For that, we refer to a suit of standards defined by Infrared Data Association for development of the communication part. Further, in order to provide the system with entity authenticity for preventing unauthorized access, we use the challenge-response protocol to design a secure link connection protocol. In addition, we have a discussion with certain concern for the design and hardware implementation of wireless fingerprint reader that plays an important role in our proposed system. With these efforts, we start to concern application areas of our proposed system. The chief application areas are physical access control and authentication. And the main focus of this work is to design an access system on the basis of our system architecture. After that, we will implement it as a real-work access system for the proof of feasibility and practicability.
