Abstract:
1. A fingerprint identification device to identify fingerprints, comprising: a fingerprint reader unit to read a fingerprint to be detected for outputting a fingerprint data; an image data processing unit to correct or compress said fingerprint data received from said fingerprint reader; a feature extraction unit to extract image features out of said corrected or compressed input fingerprint data received from said image data processing unit; a database unit to record a fingerprint database provided in advance; a fingerprint comparing unit that identifies said extracted image features received from said feature extraction unit by comparing with fingerprint data stored in said fingerprint database recorded in said database unit; a temporary recording unit to temporally record a temporary fingerprint data of said fingerprint; and a user recording unit to record said temporary fingerprint data transmitted from said temporary recording unit, wherein said temporary fingerprint data to be recorded in said temporary recording unit is said fingerprint data received from said fingerprint reader unit, and said temporary recording unit ignores said temporary fingerprint data in said temporary recording unit when said fingerprint comparing unit identifies said fingerprint, and further, said temporary recording unit automatically sends said temporary fingerprint data to said user recording unit for storing said temporary fingerprint data only when said fingerprint comparing unit does not identify said fingerprint, wherein said temporary fingerprint data enables narrowing down a location of malfunction in said fingerprint identification device.
