Digital signatures - Data visualisation

One way of obtaining proof of identity is to use digital pads that capture people's signatures.

These pads capture not only the shape of the mark, but also the speed at which it was written and the pressure applied at different points.

Songhua Xu at Zhejiang University, China, and colleagues at the University of Hong Kong have developed a way to digest that information into a digital "lily", to allow quick but robust comparisons.

The recent Eurovis Symposium, held in Berlin, brought together international researchers with new ideas about how to make data easier to interpret and act on.
