ABSTRACT:
The present invention provides technologies for narrowing down fingerprints images, which will be used for identity determination, without extracting auxiliary information such as a fingerprint pattern, thereby shortening the time required for fingerprint verification. The device according to the present invention includes a storage means26for storing characteristic information extracted from fingerprint images of registered persons, and a collection means10for collecting a fingerprint image. First, a extraction means14extracts characteristic information from the fingerprint image collected by the collection means10. Next, a narrowing means16calculates a similarity between part of the characteristic information of the person to be identified, which was extracted by the extraction means14, and corresponding part of the characteristic information of each of the registered persons, which is stored in the storage means26. Based upon the calculated similarity, the registered fingerprints that will be used for the identity determination are narrowed down. Then, an determination means18determines whether or not the characteristic information of each of the registered fingerprints, which were narrowed down by the narrowing means16, matches the characteristic information of the person to be identified, which was extracted by the extraction means14.According to this device, the registered fingerprints that will be used for the identity determination are narrowed down by using the characteristic information that will be used for the identity determination. Therefore, without extracting auxiliary information, such as a fingerprint pattern, from the collected fingerprint image, the fingerprint images that will be used in order to determine the identity of the fingerprint are narrowed down. Thus, the time required for the fingerprint verification can be shortened.
