PROBLEM TO BE SOLVED: To provide a biometrics inputting device capable of surely verifying a person himself or herself without generating any security hole even when biometrics inputting part and processing part are not necessarily integrated. SOLUTION: A fingerprint sensor 11 photographs a fingerprint picture when a finger is touched, and converts the photographed input picture into digital data, and transmits it to a picture enciphering part 13. The picture enciphering part 13 enciphers the input picture based on an encipherment key from an encipherment key holding part 12. A picture decoding part 21 decodes the signal received from the fingerprint inputted device 1 by using the key from the encipherment information holding part 24. A fingerprint feature extracting part 22 calculated features to be used for fingerprint collation from the picture information being the decoded result. A fingerprint feature collating part 23 collates the fingerprint features obtained by the fingerprint feature extracting part 22 with the fingerprint features of a user registered for an each user fingerprint registration information table 26, and transfers the result to a collated result judging part 25. |
