Fingerprint Identification Device Using Finger Attribute-Based Template Selection

The patent segments the fingerprint matching process by dividing registered fingerprints into multiple groups based on their characteristics. Instead of sequentially comparing with all registered fingerprints, the system divides the search space into segments and performs parallel matching operations across these segments, thereby reducing the time required for fingerprint verification while maintaining system manageability.

The patent performs preliminary actions by pre-processing and organizing registered fingerprints into structured formats before actual matching occurs. The system prepares reference fingerprint data in advance, creating an optimized search structure that enables faster comparison operations during the actual authentication process, thus reducing matching time without increasing operational complexity.

The patent introduces a new dimension to the fingerprint matching process by organizing registered fingerprints into multiple groups or categories based on their characteristics. This dimensional organization allows the system to handle larger fingerprint databases more efficiently by distributing matching operations across different groups, thereby maintaining productivity even as the total number of registered fingerprints increases.

The patent implements dynamic matching strategies where the system can adaptively select which fingerprint groups to search based on the characteristics of the input fingerprint. This dynamic approach allows the system to efficiently handle varying database sizes by adjusting the search scope and strategy, maintaining high productivity regardless of the total number of registered fingerprints.
