Abstract: In this paper, we propose a new concept for digital cameras to solve some of the significant problems associated with the use of digital images as evidence in a court of law. 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 combine biometric data with cryptographic hashes and other forensic data 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.
