This paper presents a novel approach of palmprint authentication based on the fusion of the phase and orientation information. This approach is an improvement of a previous palmprint recognition method - fusioncode method (A. Kong and D. Zhang, 2004). In the proposed approach, the phase information (fusion-code) of a palmprint is extracted by using four 2-D Gabor filters with different orientations, and at the same time, the orientation information (called orientationcode) of the palmprint is also extracted. The fusioncode and the orientationcode are fused to make a new feature, called the palmprint phase orientation code (PPOC). At the matching stage, a modified Hamming distance is defined to measure the similarity of two PPOCs. This approach is tested on a palmprint database containing 7605 samples and the experimental results show that the PPOC approach greatly improves the performance of the fusioncode method.
