In my previous post I have described the simple way of faking a finger for an optical fingerprint sensor.
The second experiment demonstrated the high identification capabilities of optical fingerprint capturing devices together with their absolute lack of discrimination of fake “fingers”.
During the study we managed to get the fingerprint image that was accepted by an [...]

Back in nineties I was working with TeKey Research group, supplying them raw materials for their tests.  The task was to study if fingerprint sensors accept dead fingers. Yes, I was pathologist these years and got plenty of themJ. After few experiments we realized that optical sensors cannot distinguish dead fingers from alive. Even worse, [...]
