ABSTRACT

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.
