The two-underlying premises of fingerprint identification are uniqueness and permanence. Human fingerprints are detailed, unique, difficult to alter, and durable, making them ideal for marking human identity. Matching two fingerprints is one of the widely used reliable biometric techniques and needs an expert computer system operating under threshold scoring rules, to determine they are likely to have originated from the same finger or palm.

The fingerprint identification systems consist of the capturing, processing, and storing of the fingerprint image then comparing the print with the fingerprint repository and obtaining/ storing/ displaying comparison results.
