Any software to use a mouse as a "fingerprint reader"?

[taisingera]

I just thought of something interesting to try. Is there some software to use at the Windows login screen to login using the mouse somehow? Almost like in Android there is the making a certain pattern to unlock the screen. Maybe something like clicking buttons in a certain pattern or moving the mouse around in a pattern.

Windows 8 actually has something very similar to this built in: http://windows.microsoft.com/en-us/windows-8/picture-passwords#1TC=t1

Thats actually a really cool feature. Is there any technical info on how these gesture passwords are stored securely by the OS?
