What are biometric systems?

Biometric systems are technological solutions that use individuals’ unique biological or behavioral characteristics, such as fingerprints, facial features, iris patterns, or voice, to identify and verify people. These systems are commonly used in security, access control, and identity management because they offer a high level of accuracy and convenience compared to traditional password-based methods. Biometric systems work by capturing a sample of the characteristic, transforming it into digital data, and comparing it to stored records to authenticate identity. They are widely used in smartphones, airports, banking, and government applications.
