Video-based technology makes it easy to enroll,
producing a template that in most cases is good
for the life of the subject.
Although the terminology “iris-scanning” is often
used when referring to iris recognition technol-
ogy, there is no scanning involved at all.
Iris technology is based on pattern recognition
and the pattern-capturing methodology is based
on video camera technology similar to that found
in camcorders commonplace in consumer elec-
tronics.
Like these cameras, the image capture process
does not require bright illumination or close-up
imaging.
• With a device activated by proximity sensor,
a subject positioned 3″ to 14″ from the Enroll-
ment Optional Unit is guided by a mirrored,
audio-assisted interactive interface to allow
an auto-focus camera to take a digital video
of the iris.
• Individual images from the live video are cap-
tured using a frame grabber.
• The innovative algorithm of the iris rec-
ognition process analyzes the patterns in
the iris that are visible between the pupil
and sclera (white of the eye) and converts
them into a 512-byte digital template.
• This value is stored in a database and
• Upon approaching a portal protected by
IrisAccess, proximity sensors activate the
iCAM (Iris Camera) when the subject nears
the operational range of the unit.
• The same mirror-assisted, audio-
prompted interface that the subject be-
came familiar with at enrollment helps
ensure proper positioning and speedy
recognition.
• The iCAM uses the same video and
frame-grabbing methodology to create,
select and digitize an image to be com-
