Source Device Identification

Given a digital images and a collection of digital imaging devices, such as cameras, camcorders, mobile phone cameras and scanners, the task of source device identification is to identify the source imaging device from the collection of devices that has produced the image in question, if it is known that one of the devices is responsible for that image.

Functional Technologies has developed a novel method for extracting and enhancing sensor pattern noise from photos to serve as device fingerprint in order to identify the cameras that have taken the photos. This work has led to two pending patentm (UK: 0902406.5 and International: PCT/GB2010/050247) currently owned by our client Forensic Pathways.
