Biometric identifiers like fingerprints, voice, and facial features are used for device security through biometric authentication, including face recognition and retinal scans.
Biometric identifiers such as fingerprints, voice, and facial features are utilized by device sensors for security purposes. Biometric authentication involves verifying a user's identity based on unique attributes stored in a database and comparing them for access.
Face recognition, a form of biometric authentication, utilizes facial features like skin texture and distances between features to create a mathematical expression for authentication.
Retinal scans are considered highly reliable for authentication due to the uniqueness of an individual's eye structure but may have vulnerabilities if high-quality eye images are used to trick the system.
