BIOMETRIC AUTHENTICATION SYSTEM FOR SECURE DIGITAL CAMERAS
Paul A. Blythe · 2005
iii Digital camera images are not easily accepted as evidence because it is difficult for law enforcement, insurance, news, and other such agencies to authenticate their integrity, origin, and authorship. The integrity of digital images as evidence rests on the accurate answering of a simple question: Who did what when? The unique (Proof of concept) research, presented in this dissertation involved developing the first of its kind, Biometric Authentication System (BAS), for a Secure Digital Camera (SDC), to solve the following significant problems currently associated with the use of digital images as evidence, such as: Verifying the digital camera image was not damaged or tampered with. (Integrity) Identifying exactly what camera captured the digital image. (Origin) Exact identification of the digital photographer. (Authorship) The concept of this invisible, inside the camera solution, involves losslessly embedding a biometric identifier (The photographer’s iris), with cryptographic hashes,
