Child pornographers will soon have a harder time escaping prosecution thanks to new technology in development at Binghamton University.
Scientists say the new technology can reliably link digital images with the camera used to take them, much in the same way scratches are used to link bullets with the gun that fired them.
Jessica Fridrich, an associate professor of electrical and computer engineering, said if it can be shown the original pornographic images were taken by a specific person’’s cell phone or camera, it becomes a much stronger case for prosecutors.
Fridrich and colleagues Jan Lukas and Miroslav Goljan, have applied for two patents related to their technique, which can also be used to detect forged images.
In preliminary tests, Fridrich’’s lab analyzed 2,700 pictures taken by nine digital cameras and, with 100 percent accuracy, linked each image with the camera that took it.
