Iris scanning is an authentication technique that involves mathematical pattern-recognition of the colored part of the eye, known as the iris. This method uses the unique patterns in the iris to identify and verify an individual’s identity. The iris is a muscle within the eye that controls the size of the pupil and is visible from the exterior. It has a complex structure and contains many microscopic features that are unique to each individual, making it a reliable biometric for authentication purposes.

References: The explanation provided is based on standard biometric security protocols that recognize the iris as one of the most accurate and secure forms of authentication due to its stability and uniqueness12. Iris recognition technology is widely discussed in network security literature and aligns with the objectives of the Certified Network Defender (CND) course, which covers various methods of user authentication and identity verification1.
