PROBLEM TO BE SOLVED: To provide a device and a method for collation, by which an inputted fingerprint image is automatically reversed to a turned over image and collated. SOLUTION: A feature point extracting part 12 extracts the feature point of an input fingerprint image inputted by an input part 11, a feature point preparing part 14 additionally sets a feature point to the feature point extracted by the feature pint extracting part 12, a fingerprint collating part 15 collates the input fingerprint image with stored fingerprint images stored in a fingerprint database 19 and lists up the stored fingerprint images, which satisfy a predetermined threshold, as candidate fingerprint images and a fingerprint specifying part 16 decides identity between the input fingerprint image to be displayed on an input fingerprint display area 171 and the candidate fingerprint image to be displayed on a candidate fingerprint display area 181 and specifies the same candidate fingerprint image.

Device and method for collation

PURPOSE:To confirm identity by scanning an image which is matched before again when a matched and retrieved image is sent and displaying it to the same size with the retrieved image CONSTITUTION:When features of the matched image are inputted to a matching controller 13 from an input controller 11, the features of the matched image are matched with features of file images in a file image file 14 by a matching device 15 and the similarities of respective file images are sent to the matching controller 13, so that they are arranged according to the similarities A file image No with similarity order is sent to a retrieval controller 16 and a file image with the file image key No is retrieved in an image file image memory 17 A retrieved file image corresponding to an image transmission request from a terminal controller 5 is sent to a terminal controller 5 and displayed on a display device 6 An operator compares the matched image on a monitor 3 with the retrieved image on the display device 6 to determine the same retrieved image with the matched image
