Biometrics refers to the use of unique physical characteristics, such as fingerprints, facial features, iris patterns, or voice patterns, to identify individuals and verify their identities. This area of research focuses on developing and improving technology that can accurately and securely authenticate individuals based on their physiological or behavioral traits. Biometric systems are increasingly being used in various industries, including security, law enforcement, healthcare, and banking, to enhance security, streamline processes, and prevent fraud. Ongoing research in biometrics seeks to improve accuracy, reliability, and usability of biometric systems, as well as address ethical and privacy concerns related to the collection and use of biometric data.
