Secure Digital Camera

In this paper, we propose a biometric solution to solve some of the significant problems associated with use of digital camera images as evidence in a court of law. We present a lossless watermarking solution to the problems associated with digital image integrity and the relationship to its chain of custody. The integrity of digital images as evidence rests on the accurate answering of a simple question: Who did what when? We show how to use lossless data embedding to identify from the digital image the photographer, the camera, the time when the image was taken, and verify the image integrity. We call a camera with this capability “Secure Digital Camera”. The proposed concept will provide forensic investigators with a tool that will help them establish the integrity of a digital camera image presented to the court and prove that it is a true and accurate representation of reality.
