3D Holograms Detect Fake Signatures
Roland Piquepaille writes "Several sources reported last week that a new technique that produces 3D holograms of handwriting could be used to detect fake signatures on checks, credit card receipts or other important handwritten documents. Here are pointers to Nature, Scientific American or BBC News Online. Instead of using 2D techniques to look at the sequence of pen strokes in a signature, this new method is based on 3D micro-profilometry which permits to translate the writing into an image showing dips and furrows of the sample so that anomalies can be detected. If you plan to imitate your spouse's signature, beware! Forensics have a new and very efficient tool. As an example, for the use of ballpoint pens on normal paper, the success rate was 100%. You'll find more details, references and pictures in this overview."
Uh how is this Flaimbait? A known loser advertises his link-farm of a "blog", in order to increase his advertising revenue, on Slashdot. What do you expect me to say? "Oh goody good?"
