A fingerprint is the unique pattern of ridges and valleys found on the surface of a person's fingertip. These patterns are formed during fetal development and remain unchanged throughout a person's life, making fingerprints a reliable means of identification. Each fingerprint is distinct, even among identical twins, due to the random nature of their formation. Fingerprints are commonly used in forensic science and security systems. Law enforcement agencies often use them to identify suspects or victims at crime scenes. Additionally, many electronic devices, such as smartphones, utilize fingerprint recognition technology to enhance security and provide convenient access for users.
