Mikko gave his Black Hat Europe presentation about the security issues with Microsoft/DigitalPersona’s fingerprint readers recently, which seems to have been a success.

It has gained media attention, with a few reports floating around in addition to the one I linked to recently. itnews.com.au has one of the better ones, including comments from Digital Persona. At least Mikko found one way to get through to them :)

Mikko’s slides are online here and it looks like audio will be published soon on this page. Mikko explains the lack of encryption and references the dpfp project in a few places for some of the discoveries. He also explains some of the device optics and demonstrates how the lack of encryption can be exploited to allow finger replay attacks.
