A fingerprint is a unique and intricate pattern of ridges and valleys on the surface of a person’s fingertip, formed by the arrangement of sweat pores and skin cells. This distinctive mark serves as a personal identifier, as no two individuals have the same fingerprint. It is often used in forensic science to link a person to a specific crime scene or to verify their identity. Fingerprinting has been used for centuries, with its earliest recorded use dating back to ancient civilizations. Today, it is a widely accepted method of identification and is used in various fields, including law enforcement, border control, and biometric security systems.
