样本传送型可撤销生物认证系统及其方法
摘要：
本发明提供一种样本传送型可撤销生物认证系统及其方法。生物认证系统具有包含：传送服务器，其保存样本和参数；客户机终端，其通过网络与传送服务器连接，认证用户；以及认证装置，其与客户机终端连接，在认证时取得用户的生物信息，传送服务器具有对参数进行变换生成传送用参数的参数变换部、对样本进行变换生成传送用样本的样本变换部、把传送用样本以及传送用参数传送给客户机终端或认证装置的传送部，认证装置具有取得用户的生物信息的传感器、从生物信息取得特征量的特征量取得部、使用传送用参数对特征量进行变换生成变换特征量的特征量变换部，客户机终端具有将变换特征量与传送用样本进行对照，判断一致/不一致的对照判定部。
摘要（英）：

In a biometric authentication system, a delivery server includes a parameter conversion unit which generates, by converting the parameter, a parameter for delivery, a template conversion unit which generates, by converting the template, a template for delivery, and a delivery unit which delivers the template for delivery and the parameter for delivery to one of the client terminal and an authentication device; the authentication device includes a sensor which obtains biometric information on a registered user, a feature quantity obtaining unit which obtains a feature quantity from the biometric information, and a feature quantity conversion unit which generates, by converting the feature quantity using the parameter for delivery, a converted feature quantity; and the client terminal includes a match determination unit which determines, by comparing the converted feature quantity with the template for delivery, whether or not the converted feature quantity and the template for delivery match.
