Biometric Authentication Using Typing Behavior

I’ve been pretty outspoken about my love for biometrics in healthcare. In particular I couldn’t imagine my computer without facial recognition, but I’ve also enjoyed playing around with biometric fingerprint readers and proximity readers too. Sorry, no retina scans yet. Anyone willing to send me one?

Today I came across a new biometric authentication method that recognizes a person’s typing behavior. Techcrunch described it as folows:

It’s a Flash-based interface that compares your typing style against a list of known styles and logs you in based on your individual typing fingerprint. To enroll you simply type a sentence nine times and then the system senses the pauses, mistakes, and speed of your hunting and pecking. Obviously, this doesn’t work if you have a broken hand or, presumably, you’re under duress so it’s fairly hard to crack a system using physical coercion. A cool way to add biometrics to web-based forms.

They have a test on their site, but the registration process seemed a bit onerous. Haven’t they realized the first key to a website is to let me test the product with no registration. Then, let me register when I like it? Maybe if I have some free time later I’ll register and try it out.

I wonder if something like this could merge with the OpenID movement and make this one other method of authenticating yourself to an open id enabled site. Could be pretty interesting I think.
