Ohio Forensic Guide

Binghamton University faculty Jessica Fridrich talks about digitalforensics on FOX News. Research links digital images, cameras Child pornographers will soon have a harder time escaping prosecution thanks to a stunning new technology that can reliably link digital images to the camera with which they were taken, in much the same way that tell-tale scratches are used by forensic examiners to link bullets to the gun that fired them. The defense in these kind of cases would often be that the images were not taken by this person’s camera or that the images are not of real children, said Jessica Fridrich, associate professor of electrical and computer engineering. Sometimes child pornographers will even cut and paste an image of an adult’s head on the image of a child to try to avoid prosecution. But if it can be shown that the original images were taken by the person’s cell phone or camera, it becomes a much stronger case than if you just have a bunch of digital images that we all know are notoriously easy to manipulate. Fridrich and two members of her Binghamton University research team, Jan Lukas and Miroslav Goljan, are co-inventors of the new technique, which can also be used to detect forged images. The three have applied for two patents related to their technique, which provides the most robust strategy for digital image forgery detection to date, even as it improves significantly on the accuracy of other approaches. There are about six or seven forgery detection …
