Recently, it seems many laptops have fingerprint readers. I started wondering “why”.
Most laptops have just one user. For the shared laptop, it seems to much of a fuss. I mean, in the rare case for mutual-untrustworthiness between the users, it seems to make more sense to just use passwords. Surely, that would not justify another device, and modification of the laptop design to accomodate it.
If a laptop is stolen, and there’s sensitive data, I’d assume the thieves can just pry the hard drive out and read. So, what, do people actually encrypt their drive with their fingerprint as key? I don’t know how many reliable bits are there, and probably the common laptop has their fingerprints all over it. I assume something that takes fingerprints and a scanner would be a portable solution to guessing the key in those cases.
Like any security device, we must ask ourselves, what attacks is it meant to foil? I cannot think of any.
