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： In registration, a feature array x[i] obtained by client is basis-transformed into array X[i], transformed with a transformation filter array K[i] into a template array T[i] to be registered in the client. In authentication, the feature array y[i] is basis-transformed into an array Y[i] after inversely sorting and applied to filter K by computation V[i]=Y[i]K[i]. The server obtains array e[i]=Enc (T[i]), and the client obtains e′[i]=Enc (ΣjX[j]Y[j]α−ij) and shuffles each elements. The shuffled array eσ′[i] is transmitted to the server and then decoded to obtain Cσ′[i] which provides determination of whether the feature arrays x and y match with each other or not.
摘要翻译： 在注册中，由客户端获得的特征数组x [i]被基变换为阵列X [i]，并将其转换为要在客户端注册的模板阵列T [i]。 在认证中，特征阵列y [i]在反向排序后被基变换成阵列Y [i]，并通过计算V [i] = Y [i] K [i]应用于滤波器K. 服务器获取数组e [i] = Enc（T [i]），并且客户端获得e'[i] = Enc（＆Sgr; jX [j] Y [j]α-ij）并且洗牌每个元素。 混洗后的数组e＆sgr;'[i]被发送到服务器，然后被解码以获得C＆sgr;'[i]，其确定特征数组x和y是否彼此匹配。

摘要： A biometric authentication system, authentication client terminal, and biometric authentication method are provided to reduce an expected value of the number of inputs of biometric data for authentication, while effectively preventing forgery. In a biometric authentication system, prior probabilities of enrolled users un and non-enrolled user u0 are previously set. 1:N matching is performed between feature data of a claimant v and matching feature data. The matching score is calculated for each enrolled user un. A ratio of the likelihood v=un to the likelihood v≠un is calculated for each enrolled user un using the calculated matching scores. Posterior probabilities of the enrolled users un and non-enrolled user u0 are calculated, using the likelihood ratios, and the prior probabilities of both the enrolled users un and the non-enrolled user u0. Then, determination is made by comparing each posterior probability with a first threshold.

摘要： A personal authentication method is provided for authenticating a user by cross-relation between an enrolled image and a verification image of biometric information of the user. Upon registration of the biometric information, the method generates a filter for scrambling the image and an inverse filter thereof, and applies the filter to the enrolled image generated from the biometric information to generate a registration template which is then stored to a memory. Upon authentication of the user, the method applies the inverse filter to the verification image generated from the biometric information collected from the user, and then verifies the identity of the user based on cross-relation between the verification image after application of the inverse filter and the registration template.
