PURPOSE:To perform the collation of the person himself with extremely high reliability by collating a fingerprint picture stored in a picture memory with feature point groups readout from a minutiae card, etc. CONSTITUTION:An input device 11 generates photoelectric transfer coordinates of a fingerprint pattern by means of an image pickup device such as an ITV and a light source with the aid of boundary conditions of glass from a reverse side with respect to a finger placed on a glass plate. Digital two-dimensional quantized picture data obtained such a way is stored in a memory 13, and simultaneously feature points on a minutiae card readout by a card reader 15 and information of feature-interrelation are held in a working memory 13 in a collating device 10, which precisely matches a fingerprint picture 30 stored in the picture memory 13 to the feature point group and the relation readout from the minutiae card. If the matching is successful, it is decided to be coincident, otherwise dissidence is decided. |
