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.
Absurd. Cardiac 'patterns' change over time, and altered with heart disease/dysfunction. Bio-medical based authentication must rely on non-changing biological characteristics.<p><sarcasm>Gotta hand it to them for covering the bases, though.</sarcasm>
The assignee name and "address" is spelled wrong on the page.<p>Also it would be incredibly awesome to have seamless passwords. Just pick up and go. But of course, I imagine there'd be times when it wouldn't be able give accurate consistent measurements? It seems like a rather delicate operation, i.e prone to problems.
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.
Pretty innovative I think. I imagine it wouldn't replace a password (unless it was super reliable) but just be like a shortcut for the owner. Would it detect your pulse through just your hand as you hold it normally? That's be great.
