Explanation

Biometric authentication is a type of authentication that uses the physical or behavioral characteristics of a person to verify their identity. Biometric authentication is more secure and convenient than other methods such as passwords or tokens, as biometric traits are unique, hard to forge, and easy to use. Some examples of biometric authentication techniques are retina scanner, DNA, and voice recognition. Retina scanner uses a low-intensity light beam to scan the pattern of blood vessels at the back of the eye, which is unique for each individual. DNA uses the genetic code of a person to match their identity, which is the most accurate and reliable biometric technique. Voice recognition uses the sound and pitch of a person's voice to verify their identity, which is influenced by factors such as anatomy, physiology, and psychology. These techniques fall under biometric authentication, as they use the physical or behavioral traits of a person to authenticate them.
