Iris scanning is a biometric identification method that uses mathematical patterns found in the colored ring of the eye, known as the iris, to identify individuals. This technology is based on the principle that the iris is unique to each person, even among identical twins, and remains stable over time. Iris scanning is non-invasive and does not require physical contact with the individual.

The process of iris scanning involves capturing an image of the iris using a specialized camera. The image is then analyzed using algorithms that extract unique features from the iris pattern. These features are stored in a database and can be used for identification purposes. Iris scanning is highly accurate, with false acceptance rates (FAR) and false rejection rates (FRR) typically below 1%.

Iris scanning is used in various applications, including security systems, access control, and border control. It is particularly useful in situations where a high level of security is required, such as in airports and government facilities. Iris scanning is also used in mobile devices for unlocking screens and authenticating transactions.

However, iris scanning is not without its limitations. It can be affected by factors such as eye makeup, contact lenses, and lighting conditions. Additionally, iris scanning may not be suitable for individuals with certain medical conditions, such as cataracts or glaucoma.

In conclusion, iris scanning is a reliable and accurate biometric identification method that has numerous applications in security and access control. While it has its limitations, it remains a valuable tool in the field of biometrics.
