Detecting Forged Signatures Using Pen Pressure and Angle
Songhua Xu presented an interesting idea for measuring pen angle and pressure to present beautiful flower-like visual versions of a handwritten signature. You could argue that signatures are already a visual form, nicely identifiable and universal. However, with the added data about pen pressure and angle, the authors were able to create visual signatures that offer potentially greater security, assuming you can learn to read them.

It doesn’t sound very useful to me, how will they find the pressure and pen angle of the signature I put on a check or contract? It’s not information that’s available.
