3D Holograms Detect Fake Signatures

Posted by michael on from the chicken-scratches dept.

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."

    That other gasbag (Roland Piquepaille) is back, and he wants us to read his blog so he can make some more revenue from the stupid advertisements on his page.

    Screw you.

    Let's put this into perspective:

    • Slashdot editors/admin allow, condone AND encourage link spammers/whores. ( Lo Roland, I mean you. )
    • Journalistic value of Slashdot is close to 0. ( Plainly ripping of crap from other sites; What's the last time we saw something original? )
    • Editorial blunders abound. ( Hello dupes, triples and sometimes quads... And think of the percentages in this (pdf) in the 4th paragraph )
    • Based on a broken moderation system. ( Over/Underrated, the funny mod, worthless distribution of mod rights. )
    • Developer/admin arrogance and incompetence. ( Regarding several long-standing bugs, errors, etc. )
    • Backed by worthless company that promotes outsourcing. ( Slashdot -> OSDN/OSTG -> Sourceforge )
    • Compete ignorance of what their customers actually want ( No more IT section which makes our eyes bleed. )

    In contrast, slashdot is...

    • ... Free! ( I pity the sucker who SUBSCRIBE for this though... I think you'd be better of burning your money, that would at least give you some warmth... )
    • ... Fun! ( 100k people, there's bound to be a few with my sense of humour about! )
    • ... Actual! ... Mostly... ( Ripping news from other sites makes sure the pathetic Slashdot editorial staff doesn't fuck those up, at least. )
