Fingerprint door lock
To address the need for rapid identification, fingerprint recognition systems have been developed that use electronic sensors to measure fingerprint ridges with a capacitive image capture system. Fingerprint identification is a biometric recognition process which uses a physical trait in a human body part for verifying identity. Various biometric techniques have been suggested including recognition of fingerprints, recognition of retinal scans, palm prints, DNA traces, and others. Biometric information is derived from an anatomic structure of an individual and, as such, is derived from the unique genetic content and the sum of the environmental influences on that individual. One such biometric identification system is a fingerprint recognition system. Fingerprint identification is extremely reliable, when used properly. Fingerprint matching systems that detect fingerprints and compare them with fingerprint data in a stored database have been available for some time now. Such fingerprint identification systems are being increasingly used in various devices for identifying users. For example, door locks can be operated through the matching of fingerprints instead of ID numbers. This prevents breach of security through misuse of ID numbers by unauthorized persons. In fingerprint recognition door locks, a specific user's fingerprint data are inputted and stored as reference data on a memory. The user's finger contacts an area for recognizing a fingerprint recognition module. Thus, the user's fingerprint is recognized and verified. If the user's fingerprint is identified with the reference data stored in the memory, the locking of the door lock is opened. Locks that use fingerprint matching systems are currently in use.
