Some laptops, for instance from Dell, and some PDAs, and some flash drives (such as SanDisk Profile) have a built in fingerprint recognition for security. Can this be hacked? Could a motivated civilian computer geek do it? or would it take heavy-duty resources like FBI or NSA to do so? I keep mildly sensitive files on my flash drive and want to keep these safe if I lose the flash drive. I am computer-challenged and know zilch about security. Any thoughts?
