The State Office of Criminal Investigations in Berlin is using desCRY, a new system for detecting child-pornographic images in field tests.
Bertram Nickolay of the Fraunhofer Institute for Production Systems and Design Technology IPK and other researchers developed desCRY to automate detectives' time-consuming task of clicking through hundreds of thousands of files on a suspect's computer to find the illegal content.
The software makes use of intelligent pattern-recognition algorithms that automatically analyze and classify images and video sequences. "Technologies such as facial and skin-tone recognition are combined with contextual and scene analyses to identify suspicious content," says project manager Raul Vicente-Garcia.
DesCRY searches all files in a computer, including email attachments and archives; filters searches according to size and type; and offers a wide variety of search options, such as content-based data sorting and filtering. Results are displayed in an image viewer that can accommodate several hundred photos as tiny icons, suspicious photos are singled out by placing them at the top of the list, and images can be enlarged with a mouse click and stored as evidence with a second click.
