Abstract

2DPalmHash Code (2DPHC) was proposed as a cancelable code for secure palmprint verification. In order to relieve the vertical and horizontal dislocation problems, palmprint codes, including 2DPHC, need to be shifted both in horizontal and vertical directions and matched repeatedly, which leads to high computational complexity. However, according to our analysis, horizontal-shift matching can be ignored. Therefore, the multiple-shift matching of 2DPHC can be greatly simplified. Simplified 2DPHC (S2DPHC) has three-fold advantages: (1) reduces matching complexity; (2) enhances changeability performance; (3) improves verification performance. Furthermore, the superiorities of S2DPHC over 2DPHC in terms of changeability and verification performances are validated via rigorously analysis and extensive experimentation.
