This is a pretty crazy story about how Interpol within Paris reverted a doctored photo of a man who was sexually exploiting children, the photo was blur’d using photoshop and they somehow were able to remove the blur and actually reveal the mans face. They’re not sharing what technique was used top remove the doctored portion of the photo.
Interpol Unscrambles Doctored Photo In Manhunt – jackpot777 writes in with an AP story out of Paris reporting that Interpol has distributed photos of a man suspected of sexually exploiting children. The images were recovered from pictures taken off the Internet in which the man’s face had been blurred using something like Photoshop’s Filter > Distort > Twirl tool. German police were able to recover recognizable images of the man, whose identity and nationality are not known. Interpol would not discuss the techniques used to recover the images. jackpot777 writes: “It does show one interesting facet of internet privacy that has also been noted with topics ranging from reading blurred check numbers in images to Google’s plan to blur out license plate and face data for Street View. And that is: blurring is not the same as completely obscuring. As computers become more adept at extrapolating data of different types, your identity isn’t safe unless you completely cover all those identifying features.”
