LayerOne 2007

Instructive and funny video from LayerOne 2007 about commonly used physical access control technologies. The Wiegand, proximity and RFID protocols are covered, with the focus being on hacking a common Wiegand implementation (28:50). An honourable mention must be made of the concealed bar-code card as being one of the most "embarrassing" attempts at security through obscurity. (As the presenter said: "If you ever find out someone working for you implemented such a system, fire them. Then shoot them so they don't infect the rest of us.")

More good talks focussing on privacy matters: RFIDiots and Anti-Forensics.
