It is well known that the world of art (paintings, sculptures, graphics etc) is plagued by the virus of counterfeits and this issue is particularly sensible in a country like Italy where art has flourished for centuries and where in the XX century toomany pieces of art of great painters were copied and/or counterfeited and sold for authentic. Counterfeiting is a crime which involve great amounts of money and is perpetrated at all levels, with no exclusion of the greatest art dealers. Once a style or painter has had success it is even too simple to find a epigone which either can copy a single painting or paints according to one particular style. Great examples in Italy are Morandi, De Chirico, Vedova etc. artists with a well defined (and therefore easy to copy) style. In our university we have developed and implemented a digital system which can prove without any doubt the authenticity of a piece of art and which is tamper-proof at all levels.
