biometriaa
Biometriaa is the study and application of biometric systems that use human characteristics for identification or authentication. The term covers both physiological traits such as fingerprints, iris patterns, facial geometry, voice, and gait, as well as behavioral traits like handwriting dynamics, keystroke patterns, and signature rhythm. Biometriaa systems typically operate through an enrollment phase, where a person’s biometric data are captured and converted into a digital template, and a matching phase, where a live sample is compared to stored templates to determine a match.
Common methods include fingerprint recognition, iris recognition, facial recognition, voice recognition, palm-print recognition, and behavioral biometrics.
In performance terms, systems are evaluated using metrics such as false accept rate, false reject rate, and
Biometriaa has numerous applications, including user authentication for devices, secure access to facilities, time-and-attendance systems, and
Privacy and governance: biometric data are highly sensitive; they raise concerns about consent, surveillance, and data
Future directions include multimodal fusion, on-device processing to reduce data transmission, privacy-preserving techniques, and efforts to
