【 摘 要 】

Biometrics is a highly efficient method of personal identification in civil fields. In this paper, we present a new biometrics system based on inner-knuckle-print (IKP). A new IKP image acquisition device with a finger guide is built for restricting the finger posture in a friendly way. A modified maximum curvature point method is proposed for feature extraction; it can extract the central region of the IKP line pattern robustly against illumination variation. The experimental results show that the proposed method achieves the equal error rate of 0.36%, performing better other traditional methods. In addition, it works in real-time.
