biometric authentication
Noun: The process of automatically verifying or recognizing a living individual's identity by analyzing unique physiological traits (such as fingerprints, facial patterns, or iris structure) or behavioral characteristics (such as voice patterns or typing rhythm). It is a form of identification that is intrinsically linked to the person and is difficult to transfer, share, or forget.
This term is used in contexts of security, technology, and identity verification. It refers to the method or system itself, not the act of using it. * Access to the high-security lab requires biometric authentication. * Many modern smartphones use biometric authentication, like fingerprint or face scanning, to unlock. * The system's biometric authentication proved more reliable than traditional passwords.
- As a security concept: The term is often discussed in relation to enhancing security protocols, privacy concerns, and the replacement of knowledge-based (passwords) or possession-based (key cards) systems.
- The move towards biometric authentication raises important questions about data privacy.
- In a technical specification: Used to describe a feature or capability of a device or software system.
- The new laptop includes advanced biometric authentication via a facial recognition camera.
- Biometric identification (noun): Often used synonymously with "biometric authentication," though "identification" can imply a one-to-many search (finding who a person is from a database), while "authentication" typically implies a one-to-one verification (confirming a person is who they claim to be).
- Biometrics (noun): The broader scientific field or technology concerning the measurement and analysis of unique physical or behavioral characteristics.
- Biometric (adjective): Used to describe the data or system involved.
- Biometric data is highly sensitive.
- Biometric verification
- Biometric ID
- Physiological authentication
- Multi-factor authentication (MFA): A security system that requires more than one method of authentication. Biometric authentication is commonly one "factor" in such a system, combined with, for example, a password ("something you know").
- For the bank transfer, multi-factor authentication was required, combining a password with biometric authentication.
- Liveness detection: An advanced feature within some biometric systems designed to ensure the biometric sample is coming from a live person present at the time of capture, not a photograph or recording.
- The facial recognition system uses liveness detection to prevent spoofing.
- the automatic identification of living individuals by using their physiological and behavioral characteristics
- negative identification can only be accomplished through biometric identification
- if a pin or password is lost or forgotten it can be changed and reissued but a biometric identification cannot
