What is Biometric Authentication?
Biometric authentication is a security process
that uses unique biological characteristicssuch
as fingerprints, facial recognition, or retina
scansto verify an individuals identity.
Unlike traditional methods like passwords or
PINs, biometrics offer higher security because
they are inherently linked to the individual and
more challenging to replicate or steal.

Verification
Storage
Enrollment
The captured biometric data is converted into a
digital template and securely stored for future
comparison.
When authentication is needed, the users
biometric data is captured again and compared to
the stored template to confirm identity.
The users biometric data (e.g., fingerprint,
facial features) is captured and stored in a
secure database.
