基于可撤销生物特征的匿名认证方案

Anonymous Authentication Scheme Based on Revocable Biometrics

在系统研究国内外生物特征认证方案的基础上,结合可撤销生物特征模板、El Gamal加密和私有信息检索等技术,提出一个新的可撤销生物特征匿名认证方案。该方案在认证过程中可保护用户生物特征模板的隐私,具有隐私性、匿名性、高效率等特点。

In this paper, a novel biometric authentication scheme, which is anonymity and confidentiality, is proposed. In the implementing of our protocol, some new techniques such as the revocable biometric template, E1Gamal encryption, private information retrieval were accepted. Our protocol is anonymous, which can keep a user＇s biometric privacy in authentication. Compared with the previous schemes, It has advantages as lower computation complexity and higher communication efficiency etc.
