An iris, in anatomy, is the
pigmented muscular curtain near the front of the eye, between the cornea and the lens, which is perforated by an opening called the pupil (Britannica Encyclopedia, n.d.). The human
iris is responsible for controlling the diameter and size of the pupils, which
also controls the abundance of light allowed through to the retinal in order to
protect the eye’s retina. When someone steps in front of an iris scanner, the
camera focuses automatically about three to ten inches from the person’s eye.
Once the camera captures an image, the system’s computer captures the center of
the pupil, edge of the pupil, the edge of the iris, and the eyelids and
eyelashes. It will continue to analyze the patterns in the iris and translate
them into a unique code for an individual.

            According to Forbes, as identity theft increases and information safety concerns
grow, iris scanning may be the key to finally achieving true security (Newman,
2016). Iris scanners are becoming more common for high-security applications
due to the fact the people’s eyes are so unique and do not usually change over
time. This fact makes the iris ideal for biometric identification security
applications. Blind people can also use iris scanners as long as their eyes
have irises. This makes iris identification systems effective for all people no
matter if they are blind or wear contact lenses.

            The government has already
implemented the iris scanner in high-security offices for the means of
unlocking doors, computers, and machines. Although, banking companies have been
the fastest to implement and embrace consumers using iris scanners. The use of
the system in banks have great potential to make financial matters more secure,
as well as enhance and speed up many authentication processes. For example, the
Gatwick Airport in London added an iris scanner to its passenger authentication
systems and law enforcement agencies in Missouri used the technology to build
its records management and tracking system (Newman, 2016). Iris scanning
technology is becoming mainstream, and will quickly approach our daily lives at
some point in the near future.
