Every workstation in the place has an iris scanner, which takes an initial video image of the user's iris patterns.

Those who qualify to participate in the scheme have both their eyes photographed in order to capture their iris patterns.

Anyone whose iris pattern is not in the data bank doesn't get in.

I had his iris patterns and color imprinted on them.

Zammit wondered if the scanner would sound an alarm upon seeing the same iris pattern twice in a row within less than a minute.

The idea that iris patterns could be a form of identification has been discussed for decades.

By 1987, the pair had been granted a patent on the idea of using iris patterns for identification.

Sensar has adapted its technology for use in computers that can identify faces and iris patterns, or search for movement and change in a scene.

The result is a set of complex numbers that carry local amplitude and phase information about the iris pattern.

Alcohol consumption causes recognition degradation as the pupil dilates/constricts causing deformation in the iris pattern.
