Fingerprint technology uses unique fingerprint patterns to identify and authenticate individuals. It captures fingerprint images using optical or capacitive sensors and extracts distinctive minutiae features. An advanced minutiae-based algorithm then matches input fingerprints to templates in a database for identification, or to a single template for verification. Fingerprint biometrics provides highly accurate identification at a low cost and is seeing increasing usage across applications due to its convenience compared to other biometrics like voice or iris recognition. It has become a major industry due to the need to reliably protect sensitive personal information.
