Julie Lerman points out that the DoesYourAppThinkInInk contest is wrapping up.
i just spent the last couple days putting an entry together and made it into the /tabletSign article. it is a signature biometric for logging into web sites with a Tablet PC. an interesting part is that the user does not have to use a text-based password ... they could draw a hieroglyphic ... or whatever. it also uses WSE security to communicate back to the web site, so that the biometric info cannot be tampered with or viewed (i.e. Xml-Signature and Xml-Encryption). it does all this without requiring the user to change their default web browser security settings
