2Introduction
IriShieldTM-USB MK 2120U camera hardware is a revolutionary, monocular design that delivers the
highest quality auto-capturing iris acquisition with an ease of use never achieved by older camera
systems. The system offers contactless, fast, standards-compliant iris acquisition in a small form factor
that is easy to house in a variety of packages. IriShieldTM-USB includes an embedded CPU that enables
on-board computing for automated quality-based iris image capturing, recognition, and verification
without taxing the computing power of the host PC. IriShieldTM-USB provides a PKI-based security
infrastructure which creates a self-generated RSA-2048bit key and generates a random one-time AES-
256bit key for each session. As a result, this camera can operate with nearly any host PC or mobile
computing device. With its USB interface, compact design, and sophisticated, easy-to-integrate
accompanying software, IriShieldTM-USB represents unprecedented value for iris biometrics
identification.

4Warnings and Precautions
4.1 Hardware
IriShieldTM-USB device includes sensitive electronics and optics. It is possible for IriShieldTM-USB device
to get these electronics damaged if you do not follow proper precautions:
Clean regularly to remove dust, but do not use any cleaning solutions. Only wipe the device with
a smooth cloth or towel. Keep the lens free of dust and dirt, and use a special optical cloth in
order to not scratch optics.
Do not allow water to leak into the device or operate the device in humid conditions where
water might condense upon the electronics.
Do not operate device in places where temperature reach extremes beyond the stated range.
Do not place the device next to heating equipment.
Do not place magnets near the device.
Do not apply voltage or current beyond the stated range.
Do not use the device for any purposes beyond those specified.
Do not disassemble components from the boards or alter wiring or board design.
Do not drop the device or submit it to sudden impact or mechanical stresses.
Handle the electronics with proper anti-static protection and techniques to prevent shorting any
microchips.
Any damage to the device caused by these activities will void the warranty.
This document describes guidance to use IriShieldTM-USB device as well as IriSmartEye 2000 application
in the most proper way. If user does not follow the guideline, errors or wrong results may occur.
4.2 Software
To prevent faulty matching, the following guidelines should be considered carefully by developers.
Please be warned that the threshold numbers given in this section are only for reference. Developers
should have their own decisions to balance between accuracy and usability based on their iris database.
4.2.1 Enrollment
Image quality: Total score and usable area should be greater than 70 (>70), the captured
image is ideal for enrollment. If either total score or usable area is less than or equal to 50
(<=50), the image should be rejected.
Horizontal rotation: For enrollment, horizontal rotation angle of eye postures should not
exceed ±10 degrees.

IriShieldTM-USB MK 2120U Basic User’s Guide
Deduplication: Before enrolling a template, make sure the template does not match with
other enrollees’. Deduplication can be done automatically by device or manually by
developers.
4.2.2 Matching
Image quality: Total score and usable area should be greater than 30 (>30). Otherwise, the
image should NOT be used for matching.
Horizontal rotation: For matching, horizontal rotation angle of eye postures should not
exceed ±20 degrees.
Matching decision: The decisive distance value is the smallest distance among those returned
from 1:1 and 1:N comparisons. If the distance is smaller than or equal to the genuine
threshold, a positive match is claimed. If the distance is greater than the imposter threshold,
the query image is from an imposter. Otherwise (i.e., the distance is greater than the genuine
threshold and smaller than or equal to the imposter threshold), there is some uncertainty due
to, e.g., low image quality, occlusion, or pupil dilation, and the user should have his/her iris
image recaptured with an eye wide opened and do the matching again.
