基于LGBP与Bloom滤波器的可撤销掌纹模板生成方法
Cancelable palmprint templates based on LGBP and Bloom filters
摘要
Abstract
In order to effectively protect users' biometric information and improve the security and privacy of palm identity verification system,this paper proposed a method to generate cancelable palmprint templates.The multi-resolution and multi-orientation Gabor filters extracted Gabor magnitude features of palmprint.After obtaining the uniform LBP pattern histogram sequence of Gabor magnitude pictures,Bloom filters achieved many-to-one mapping and position scrambling.Then it generated a cancelable palmprint template after irreversible transformation.Both theoretical analysis and experimental results show that this method can not only protect the original palmprint feature,even the key is stolen or shared,it remains high recognition rate.关键词
