Biometric is a secure identification system to check for identity and helps prevent unauthorized access. It provides an
automated way for identification and verification with the help of one’s physiological and behavioral characteristics. It also
provides an advantage over the basic method of password and PIN protected systems that are vulnerable to being lost or stolen, as
it is more stable and secure. Various biometric systems are developed based on different physical characteristics like the face,
voice, fingerprint, iris, etc. Among all these, iris recognition is found to be a more reliable and secured authentication system. Iris
recognition is a technique to identify an individual based on the unique patterns present in the eye. These patterns differ even in
identical twins.
