    摘要： In personal authentication using biological information, biological information is protected without degrading the authentication accuracy. An obtaining unit 311 of a biological information obtaining apparatus 301 obtains biological information for authentication, and an extracting unit 312 extracts first feature information from biological information for authentication. A generating unit 321 of a biological information collating apparatus 302 generates encrypted position correction information, and encrypted position correction information is transmitted to the biological information obtaining apparatus 301. A correcting unit 313 decrypts encrypted position correction information to obtain position correction information, and by correcting first feature information, performs alignment between first feature information and second feature information extracted from biological information for registration. A transforming unit 314 transforms corrected first feature information, and transmits transformed first feature information to the biological information collating apparatus 302. A collating unit 324 collates transformed first feature information and transformed second feature information stored in a storing unit 325, and transmits a collation result to biological information obtaining apparatus 301.

    摘要： To provide cancelable biometrics, random projection transforms are used to produce transformed biometric data that may be used for authentication purposes. Each random projection transform provides a one-way or irreversible transformation such that the resulting transformed biometric data alone cannot be used to reconstruct the biometric data. Enrollment and backup transforms are produced based on enrollment biometric data. Authentication is possible by similarly transforming authentication biometric and then securely reconstructing the enrollment and authentication biometric data for comparison. In a similar manner, the enrollment and backup transforms may be used to reenroll biometric data when its corresponding transformed biometric data is compromised without requiring further user intervention.

    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.
