FAQs

The processing of an image to create a template is fast but highly dependent upon the memory and speed of the PC handling the processing. Creating a template normally requires no more than a fraction of a second.

The iris template is a special biometric reference file in which iris features have been stored for the purpose of matching. Matching compares the stored iris template against the new iris features extracted from the recently captured iris image data.

Soft contact lenses are unlikely to cause problems, but both glasses and hard contact lenses might produce glare or partly obstruct the iris. If the glare is large enough, identification may be prevented. Removing glasses before capture, especially during initial enrollment, is the best way to ensure a high-quality image.

No, Lasik eye correction should not cause any trouble with iris recognition. In fact, few eye surgeries or diseases directly impact the iris. Examples of issues that might interfere would include surgery that leaves scars over the iris (scars may prevent identification if the comparison is against a record of the eye before surgery) and intraocular lens implants (lens implants may produce significant glare that can make it challenging to capture a high quality iris image).

A measure of dissimilarity of two biometric feature set represented by two templates. A smaller distance implies the more similarity. It means there is greater possibility that those templates belong to the same eye of a person.

 
Yes, you can extract iris images or templates onto your own computer by using the associated SDK.

IriTech offers iris recognition hardware (cameras) and software (SDK) for each customer's custom-development. As each of our customers has different business needs, we generally offer our products as development toolkits that will ultimately require end-user systems integration. If you need a ready-to-be-integrated platform, we can connect you to one of our systems integration partners for development.

The data transmitted from an iris camera and server can be an image or template. The iris cameras support the entire ISO image standard. The standard iris image is VGA (640x480 pixels), gray scale, and approximately 300 kB. Our template types are split into 3 categories, (1) S-template (Simple Template): 1.4 kB, (2) D-template (Detailed Template): 63 kB, and (3) N-template: 4 kB. S- and D-templates are used by our original SDK, while N-templates are state-of-the-art templates for our IriMaster software. When the highest possible degree of matching speed and accuracy are required, we recommend IriMaster and the N-template.

IriMagic and IriHerald must be coupled with separate iris template generating and matching programs for operation. If you do not already have iris recognition and matching programs, we highly recommend our iris SDK program, which won top honors in the IREX I test performed by the US National Institute of Science and Technology (NIST). Our algorithm technology is great for any large-scale project requiring extreme accuracy.

We do not recommend operating the camera device through a USB Hub.

There is no limitation when operating under normal conditions.

For data storage: -40°C to +85°C
For operation: 0°C to +50°C
0% to 95% humidity, non-condensing

No, it emits very low infrared light (less than 2% of the LED Eye Safety Standard Regulation). It is harmless to a user’s eyes, but it could lead to eye fatigue if stared at for a long period of time. It is advisable to capture iris images as quickly as possible.

To support users with secure communication between IriCAMMES device and host, IriTech provides a Security Infrastructure within each device. This Security Infrastructure is based on Public Key Infrastructure (PKI). This PKI-based structure takes advantage of the prominences of both symmetric and asymmetric cryptography algorithms. In particular, all functions relating to image and template transmission between host and device through USB bus are provided with cryptographic versions employing the high security level 256-bit AES and 2048-bit RSA.

De-duplication is 1:N matching to ensure that each recipient obtains and maintains a single, unique credential. Our enterprise software, based on the NIST IREX I top-rated iris SDK, is capable of carrying out de-duplication.

To use iris images taken by another iris camera you will need to be licensed IriTemplateGenerator and IriMatchEnhancer. The IriTemplateGenerator can create template from various iris image formats including ISO standard formats.
