摘要

In consideration of an increasing demand to adopt the biometric technology to minimize potential security risks, the paper presents a consumer-level biometric system for automatic physical access control. Through development of a near infrared imaging device for biometric acquisition of dorsal hand vein patterns and computation efficient image processing methods, the proposed system is shown to possess a range of desirable operation characteristics for real-world use, which include reliable in identification, convenient to use, high in security, fast in response, low in cost, and simple for installation.
