Did I just hear a sigh of relief from some of you or was that
just me? One day soon the unique pattern of your heart's beat
could act as the password that unlocks your hard drive just by
touching your keyboard. The scientific team behind the concept
successfully tested the concept of translating a human heartbeat
into an encryption key by taking an electrocardiograph (ECG)
reading from a person's palm. They were then able to extract the
signature beat the heart makes and generate a secret key as part
of an encryption scheme. The secret to the encryption being,
well, secret, is that not only is your heartbeat unique to you,
it also has an irregular pattern that never repeats. So the
encryption scheme is based on the math behind the chaos theory,
in which small changes to initial conditions lead to different
outcomes. You won't get the same key twice. The goal is to build
this system into external hard drives so that users could both
encrypt and decrypt their devices simply with the touch of a
hand. I think my
