Vein patterns are typically read by sensors based on the red blood cells’ tendency to easily absorb near-infrared rays after transporting oxygen in the veins.
The technology has been adopted for ATM use, entry to facilities and other purposes. But it isn’t foolproof. Scientists at the institute say that photographing fingers from a distance with a digital camera can reveal the vein patterns. “Biometric information used for personal identification does not change throughout one’s life, so the risks will remain once it is stolen,” said Isao Echizen, a professor at the institute. “I want to establish a technology to prevent unintentional leaks of such information.”
uh: too late.
I wonder about using finger vein identification
As a young girl, my hands would go cold when I was nervous. Wouldn't this affect the veins?
Ditto for Retinal scans: We would photograph the retinas of our diabetic patients to check for neovascularization from diabetic retinopathy. So those patients would fail, as would those who get retinal bleeds or other pathology.
Well, what about Iris scans? I wonder about that too. Would uveitis or corneal clouding confuse that type of identification?
and alas that is easy to spoof too:
and then there are facial scans.
and now your photo is being scanned and filed on Facebook

But it's not all bad:
it's nice to know that privacy still exists: government needs a warrant to spy on you:
uh oh...
