Biometric Face Recognition System (4)

Iris and Retina scanning Two conventional
Biometrics face recognition systems

Nothing is more accurate and genuinely effective
in establishing the identity of a person than the
modern-day biometrics technology. Biometric face
recognition system is a distinct model to
identify an individual based on certain facial
characteristics and patterns. There are many
systems that can capture the facial
characteristics to establish the ID of a person.
However, Iris Recognition and Retinal scanning
technologies are popular modalities of the facial
biometric system.

They are similar and different in many ways.
Based on the kind of environment and the number
of people likely to be screened through the
biometric face recognition system both the
models have their own share of impeccable
benefits.
Let us do a quick review on both these biometric
recognition systems.

Why biometric facial recognition through eyes?
Eyes are the windows to the world. Just like
fingerprint technology, the eye scanning
technology too has a unique biometric
characteristics unique to every individual. They
are better than the fingerprint scanning as it
involves contactless identification. While
retinal scanning is a more advanced and invasive
in its operation, iris recognition is a
non-invasive and more comforting modal on the
biometric list.

The similarities
Iris Recognition and Retinal scanning biometric
face recognition system have certain similarities
as listed below.
O Non-contact identification consoles O Two-eye
biometric identification O Highly stable in its
application in different environment and time
period O Not much change with age-related or
diseases O No chance of duplication O Accuracy
is 99.997 with zero tolerance O Easy and
manageable data inputs that take less storage
space

The differences
Let us dig deeper into the world of biometric
face recognition systems by understanding the
technologies from close quarters.

Retinal Scanning
O The blood streams and veins lining the thin
tissue inside the eyes are laid out uniquely in
every person. The sensor captures these vein
lines with the retina structure to gauge the
identity of the person. O Even in case of severe
debilitating disease affecting the eyes, the
Retinal Scanning biometric face recognition
system delivers accurate results. O The retina
of a person remains unaltered throughout life,
and thats why new born babies are identified
through Retinal Scanning. O The biometric
identification system is done by passing a light
beam tracing the retinal area. The retinal
imaging is unique for each person owing to the
differential thickness of the tissue, veins
layout and also the light absorption capacity of
the tissue. O The imaging produced by the light
beam traced on the retina is converted into a
computer code which is mapped to the system for
future reference during identification and
access-related activities.

Unlike Retinal scanning, Iris recognition is done
by using high-definition camera powered by
illuminated IR beams. Iris Recognition is more
acceptable and affordable for organizations as it
can be more readily integrated with the existing
Employee Self Service portals and attendance
systems. Moreover, the ID of a person can be
established by Iris Recognition done from a
vantage point. The person may not have any clue
about the biometric recognition system in place,
especially important in high-security destination
and protected areas like banks, airports,
military offices and government units.
