Q1: What is “Biometrics”?
Biometrics is a general term used alternatively to describe
a characteristic or a process.
 As a characteristic: A Biometric is a measurable
biological (anatomical and physiological) and behavioral
characteristic that can be used for automated
recognition.
As a process: A Biometric is an automated method of
recognizing an individual based on measurable
biological (anatomical and physiological) and behavioral
characteristics.

Q2: What are the common Biometrics?
Biometrics commonly implemented or studied include
fingerprint, face, iris, voice, signature, and hand geometry.
Many other modalities are in various stages of development
and assessment.
Q3: Which Biometric technology is the best?
There is not one Biometric modality that is best for all
implementations. Many factors must be taken into account
when implementing a Biometric device including location,
security risks, task (identification or verification), expected.
Q4: What is the difference between recognition, verification
and identification?
Recognition is a generic term, and does not necessarily
imply either verification or identification. All Biometric
systems perform “recognition” to “again know” a
person who has been previously enrolled.
Verification is a task where the Biometric system
attempts to confirm an individual’s claimed identity by
comparing a submitted sample to one or more
previously enrolled templates.
Identification is a task where the
Biometric system attempts to determine the identity of an
individual. A Biometric is collected and compared to all the
templates in a database. Identification is “closed-set” if the
person is known to exist in the database.

Q5: What if identical twins use a Biometric device?
Although identical twins may appear the same to the human eye, their
biological and behavioral characteristics are usually subtly
different. The automated methods implemented in some Biometric
devices can often identify such differences and differentiate
between two seemingly identical twins.
