A fingerprint database is a collection of digital records that store fingerprint images and related information. These databases are used by law enforcement agencies to identify individuals based on their unique fingerprint patterns. Each person's fingerprints are distinct, making them a reliable method for identification. Fingerprint databases can also be used in various applications beyond law enforcement, such as in security systems and access control. By comparing a person's fingerprint against the stored records, these systems can quickly verify identities, enhancing security in places like airports and government buildings.
