I've done a lot of work with heartbeat signatures, and this is a promising idea. Each person has a certain set of easily identifiable characteristics to their heartbeat, such as notches, and creating something like an FFT to create a signature could potentially be a great method of identifying a user.

Are any of these identifiable characteristics really that invariable? What if someone starts exercising a lot, or loses 200 pounds, or starts taking medication that affects the heart/blood pressure, etc..? I imagine being locked out of your account and trying to diagnostic your heart must be a pain...

On the plus side, it'd be like a regular heart exam. If you can't access your account, you might have a bigger problem.

I was thinking today about a mouse that could detect heart rate, in the same manner as a cardio machine detects it. I don't know why you would want to use it as a password, however it could be useful in biofeedback.

A real mouse or a computer mouse?

Computer mouse!

So if I came back from a long running am I still able to unlock my heartbeak signature protected device?

Sorry for the late reply, but yes. The amplitude and frequency of the signal would still be different (your heart is beating harder and faster), but the characteristics would still be the same.
