What is Facial Recognition?
                     What is Facial Recognition?
INTRODUCTION
Facial recognition is a category of biometric software 
that maps an individual's facial features 
mathematically and stores the data as a faceprint.

TECHNOLOGY USED
The software uses deep learning algorithms to 
compare a live capture or digital image to the stored 
faceprint in order to verify an individual's identity.

HOW IT WORKS?
The software identifies 80 nodal points on a human 
face. In this context, nodal points are endpoints used to 
measure variables of a person's face, such as the 
length or width of the nose, the depth of the eye sockets 
and the shape of the cheekbones.

HOW IT WORKS CONT.
The system works by capturing data for nodal points on 
a digital image of an individual's face and storing the 
resulting data as a faceprint. The faceprint is then used 
as a basis for comparison with data captured from faces 
in an image or video.

FACIAL RECOGNITION SYSTEM
Even though the facial recognition system only uses 80 
nodal points, it can quickly and accurately identify target 
individuals when the conditions are favorable. 
However, if the subject's face is partially obscured or in 
profile rather than facing forward, this type of software is 
less reliable.

USE CASES
Facial recognition can be used for a multitude of applications, 
from security to advertisements. Some example use cases 
include:
● mobile phone manufacturers, such as Apple, for 
consumer security;
● airports, via The Department of Homeland Security, 
to identify individuals who may overstay their visas;

USE CASES CONT.
Facial recognition can be used for a multitude of applications, 
from security to advertisements. Some example use cases 
include:
● law enforcement through collecting mugshots to 
compare against databases from local, state, and 
federal resources;
● social media, such as Facebook, to tag individuals in 
photographs;
● business security, as businesses can use facial 
recognition for entry to their buildings.

BENEFITS
With the use of facial recognition comes a host of potential 
benefits, including:
● No need to physically contact a device for 
authentication- compared to other contact-based 
biometric authentication techniques such as 
fingerprint scanners, which may not work properly if 
there is dirt on a person's hand
● Improved level of security

BENEFITS CONT.
With the use of facial recognition comes a host of potential 
benefits, including:
● less processing compared to other biometric 
authentication techniques
● easy integration with existing security features
● accuracy of readings has improved over time
● can be used to help automate authentication

SECURITY & PRIVACY CONCERN
The information could then be accessed by a hacker, 
and an individual's information spread without ever 
knowing it. 
This data could be used by Government agencies or 
advertisers to track individuals as well.
