摘要： Upon registration, a client extracts plural feature points and information (identification information) by which each of the feature points can be identified, from a user's fingerprint, and randomly generates a transformation parameter for each feature point to transform the coordinates and direction. The transformed identification information (template) is transmitted to an authentication server and stored in a,memory. The identification information and transformation parameters of the feature points are stored in a memory medium of the user. Upon authentication of the user, the client extracts feature points from the user' s fingerprint, and identifies the feature points by the identification information in the memory medium. The client transforms the identified feature points by reading the corresponding transformation parameters from the memory medium, and transmits the transformed information to the authentication server. The server verifies the received identification information against the template registered in advance, to authenticate the user.

摘要翻译： 在登记时，客户从用户的指纹中提取多个特征点和可以识别每个特征点的信息（识别信息），并随机地产生每个特征点的变换参数以变换坐标和方向。 转换后的识别信息（模板）被发送到认证服务器并存储在存储器中。 特征点的识别信息和变换参数存储在用户的存储介质中。 在认证用户时，客户端从用户的指纹中提取特征点，并通过存储介质中的识别信息来识别特征点。 客户端通过从存储介质中读取相应的转换参数来转换所识别的特征点，并将转换后的信息发送到认证服务器。 服务器根据预先注册的模板验证接收到的识别信息，以认证用户。

摘要翻译： 在登记时，一客户端中提取多个特征点，并且，通过该各特征点的可被识别的指纹信息（识别信息），从用户的，和随机生成的速率为每一个特征点变换坐标和方向的变换参数。 经变换的识别信息（模板）是反式mitted在认证服务器并存储在，存储器。 的特征点的识别信息和变换参数被存储在用户的存储介质。 一旦用户的身份验证，客户端从用户的指纹中提取特征点，并且通过在存储介质中的识别信息识别的特征点。 客户端通过转换从存储器介质读取对应的变换参数标识的特征点，并将该变换后的信息到认证服务器。 服务器验证对预先注册的模板接收的标识信息，对用户进行认证。
