BBC NEWS | Technology | Mice sign on the dotted line: “The system could be used to verify that people using a website are who they claim to be or provide another level of checking when people use credit cards online. “

I don’t see this getting really popular. Most people I know can’t draw a straight line with a mouse, much less sign something.

If it gets popular, I see problems. People who use a mouse over and over for drawing a familiary object get better and better at drawing what it is in their mind, thus changing the median image of what this software finds out in the first 20 scans of the image drawn. I’d like to see more extensive testing on this before it’s declared 99% accurate.
