Turns out, you see, that fiction may be truer than truth (as it were). The dynamic duo known as the Mythbusters
managed to crack a fingerprint door lock
with a) a latex copy of a fingerprint b) a copy made with ballistics gel and c) a
of the fingerprint and saliva.
When you think about it, fingerprint door locks aren’t much more secure than traditional door locks—in fact, they’re theoretically
secure. After all, while you can lose a physical key that someone else can find, it doesn’t require you to “lose” a fingerprint for someone else to find it. You leave fingerprints
. So, there are millions of keys for your door just lying around, waiting for people to find them.
