Subverting Fingerprinting

squizzar writes in with news of a 27 year old Chinese woman who was discovered to have had her fingerprints surgically swapped between hands in order to fool Japanese immigration. "It is Japan's first case of alleged biometric fraud, but police believe the practice may be widespread. ... The apparent ability of illegal migration networks to break through hi-tech controls suggests that other countries who fingerprint visitors could be equally vulnerable — not least the United States, according to BBC Asia analyst Andre Vornic." Time for some biometric escalation. Could iris scans be subverted as easily?

FBI fighting this since the 1930's

"other countries who fingerprint visitors could be equally vulnerable — not least the United States", according to BBC Asia analyst Andre Vornic.

Vornic needs to do some research. Criminals in the US have been attempting to surgically alter or mask their fingerprints since at least the 1930s, and the FBI has been researching the techniques since then as well. I remember reading about this in a book from the 60's, where a counterfeiter surgically swapped his prints around, and the FBI recognized them, out of order, and matched them back up with the original fingers.

According to mythbusters you could get past most scanners with a photocopy of someone else's fingers :P

Iris size: Trivial

Also the eye may dilate as you kill them which will also fuck the result.

Mydriasis happens with death, indeed.
But it's almost trivial to induce myosis instead, using the proper chemicals. (Cocaine, as an example of something which won't be difficult to obtain for would-be criminals. As a bonus, this same substances doubles as a way to kill the victim through overdoses AND a way to preserve the iris in myosis).
