Fingerprint-Protected USB Sticks Cracked
juct writes "Manufacturers of USB sticks and cards with fingerprint readers promise us that their data safes can only be opened with the right fingerprint. In their tests, heise Security found that it is easy to bypass the authentication and get access to the protected data. This works by sending a single USB command, using the open source tool PLscsi, that changes the accessible partition. They found the vulnerability in several USB sticks that use the same chipset. The article concludes: 'The fingerprint sensors in the products mentioned above apparently only serve one purpose: they mislead interested buyers. They do not provide any significant level of protection. We can only recommend that these products not be purchased.'"
My biggest problem with finger print locks is that they use only my finger to open them, and I don't want someone using my finger to open a lock when I'm not there. A good rule of thumb is that you should never lock anything with a finger print that is more valuable to a thief than your finger is to you, or that is harder to crack than cutting off your fingers.
This is why I don't ever want a car with fingerprint locks. Pretty much the same for laptops. I am going to put a fingerprint reader on my pool gate though, as it will be easier for someone to just kick the gate open, or jump the gate than it is for them to mug me and take my fingers.
