Hopefully the person does not have Argyll Robertson pupils https://en.wikipedia.org/wiki/Argyll_Robertson_pupil which is seen in late stage syphilis and causes the pupil not to react to the light.
Also, another thing is that they should make sure that they train their system with dark eyed people. Often the iris is very easy to identify if people with light colored eyes. In people with dark eyes, it may be more difficult.
Or they (what percentage would that be?) could just use an alternative method. Like people with glass eyes would.
Surely this is a concern (and presumably a solved problem) for any iris scanner, regardless of whether it tries to detect if the eye responds to stimuli.
The Apple-style IR Mesh doesn't care what your skin color is, everyone is grayscale as far as it is concerned :D
Now, one may point out that if both pieces of information were being kept entirely private and were being secured with industry standard security this different wouldn't matter. I'll leave the implications of this for the reader to ponder upon.
This is new? In 2019? Really? I find that so hard to believe.
> the process takes about 3 seconds
> For comparison, even iris-recognition systems that require just one snapshot usually take about that much time to make an identification.
I feel like Robin Williams fresh out of Jumanji yelling "WHAT YEAR IS IT?"
"Briefly, it was found that when light is flashed on a normal eye that is accommodated for the dark, there occurs a latent period of 0.1875 second before the pupil begins to contract. Then there follows a rapid primary contraction for 0.4365 second at the rate of 5.48 mm. per second. This is succeeded by a secondary contraction of 0.3125 second at the slower rate of 1.34 mm. per second"
Doesn't explain 3 seconds, but perhaps 1 second or so.
Coz they could add a brainwave scanner that measures the reaction to the input of the eye, or have a higher resolution camera that measures blood flow being active in the eye. Many avenues of addressing this. But as a previous comment mentioned - generally easier to have a physical person next to the iris. After all, not like there is a shortage of humans to do jobs in the World today.
Yeah, sure, why? Who needs that level of security? Governments that can already afford to pay someone to stand by that door if it's so important?
(I worked briefly in security ... well, humans are really unreliable)
You just killed a person and extracted their eyes to use to open some door. I think you have the budget for something that you can make for $200 with Lego Technic...
There have been people tortured to death who never gave up important secrets, so that might not be an option...
