基于细节点邻域信息的可撤销指纹模板生成算法
Generating Cancelable Fingerprint Templates Using Minutiae Local Information
摘要
Abstract
It has become critical to improve the security of the fingerprint templates.This paper,we propose a cancelable fingerprint template based on minutiae local information.First,we extract fingerprint minutiae feature after the preprocessing,then we use the improved Tico sampling structure to extract texture feature of minutiae adjacent area.Finally,the fingerprint template is generated by combining the user PIN.Our design of fingerprint matching algorithm draws on the experience of greedy algorithm.The experiments results on FVC2002-DB1 and DB2 show that the algorithm not only achieves good recognition performance but also fulfills revocability,diversity and non-invertibility,and that without reducing system recognition performance,the improved sampling structure extends the sampling structure of minutiae description.关键词
