Iris recognition is an automated method of biometric identification that uses pattern-recognition techniques to identify a person, based on the unique patterns in the iris of their eye.Iris recognition systems capture and process images of irises. The system then compares the pattern in the iris to a database of known iris patterns, in order to identify the individual.

Iris recognition systems are used for a variety of purposes, including security and authentication. They can be used to identify individuals at security checkpoints, or to grant access to secure areas.Iris recognition systems are also being used in a number of other applications, such as time and attendance tracking, and patient identification in healthcare.

The iris is the colored ring around the pupil of the eye. The patterns in the iris are unique to each individual, and do not change over time.Iris recognition systems use a camera to capture an image of the iris. The image is then processed to extract the unique pattern of the iris. This pattern is then compared to a database of known patterns, in order to identify the individual.

Iris recognition systems are accurate and reliable, and can be used in a variety of applications.
