Iris scans are a biometric identification method that uses the unique patterns in the colored part of the eye, known as the iris, to verify a person's identity. Each individual's iris has distinct features, making it a reliable way to distinguish one person from another. This technology is often used in security systems, such as smartphones and airport security checks. The process involves capturing a high-resolution image of the iris using a specialized camera. The image is then analyzed using algorithms that identify specific patterns and characteristics. Iris scans are considered highly accurate and are less intrusive than other biometric methods, such as fingerprints.
