    摘要: At a registration time, a feature data array for registration is generated from biometric information acquired by a client, and a position correction template and a comparison template obtained by converting the feature data array for registration are registered in a server.At an authentication time, a feature data array for authentication is generated from biometric information acquired by the client, and converted feature data for position correction obtained by converting the feature data array for authentication is transmitted to the server. The server detects a position correction amount of the feature data array for authentication relative to the feature data array for registration using the position correction template and the converted feature data for position correction, and transmits the position correction amount to the client. The client corrects the feature data array for authentication using the position correction amount and transmits the converted feature data array for comparison to the server. The server calculates a distance between the comparison template and the converted feature data array for comparison and determines success or failure of the authentication on the basis of the distance.

    摘要: The present invention captures user's biometric data during enrollment and converts it by a given conversion parameter to create a template. It creates verification information for the conversion parameter, and enrolls it in an authentication server together with the template. The conversion parameter is stored in an IC card or the like for issuance to the user. During authentication, the authentication server verifies that the authentication terminal knows the conversion parameter, using conversion parameter verification information. Next, the authentication terminal converts user's biometric data newly captured by a conversion parameter to create matching information, and transmits it to the authentication server. The authentication server matches the matching information with the template to determine whether the user is a principal.

    摘要: A template sharing processing is performed between a first authentication server and a second authentication server. A client terminal generates two parameter differences, one of which is sent to the first authentication server, and the other to the second authentication server. The first authentication server transforms an already-registered template with the received parameter difference to create a temporary template and sends the temporary template to the second authentication server. The second authentication server transforms the received temporary template with the already-received parameter difference to create and register therein a further transformed template. A storage medium stores therein only a single master key for generating a parameter.

    摘要: The authentication server authenticated by a public key certificate at the time of authentication generates a difference parameter, transforms a template by the difference parameter to create a temporary registration template, and transmits the difference parameter to a tamper resistant device. The tamper resistant device generates a temporary parameter from the held transformation parameter and the difference parameter. A client terminal transforms feature using the temporary parameter, and generates temporarily-transformed feature. An authentication server receives the temporarily-transformed feature, and verifies whether the temporary registration template is in agreement with the temporarily-transformed feature.

At authentication time, feature data array for authentication is generated from biometric information acquired by the client, and converted feature data for position correction obtained by converting the feature data array for authentication is transmitted to the server. The server detects position correction amount of the feature data array for authentication relative to the feature data array for registration using the position correction template and the converted feature data, and transmits the position correction amount to client. Client corrects the feature data array for authentication and transmits the converted feature data array for comparison to the server. Server calculates a distance between the comparison template and the converted feature data array for comparison and determines success or failure of the authentication on the basis of the distance.

    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。
