I used to work for a VPN company and one of the authentication devices that we tested was a biometric scanner. The funny thing is that if you take a gummy bear, you can remove a print from the scanner and use it to make a viable print. We did a proof of concept for a federal branch who laughed when they heard the idea but nearly **** when they saw how a 50 cent bag of candy could be used to gain access to millions of dollars worth of research material.

The VPN company that used to work for is now pursuing retina scanning technology. I think that the gummi bear attack will have to be shelved on this one .
