Abstract: Proving the authenticity and source of an image has traditionally been done with a lm negative. However with the shift to digital cameras this proof has been lost. Image manipulation has also become a lot easier to do. This project aims to create a digital negative that is, a digital equivalent of lm nega- tives for proof of authenticity and source. We are aiming to prove that a set of images is a complete set of unaltered images as taken by a digital camera on the day of photography. modern cryptographic techniques such as public key cryptography, cryptographic hashes and blockchains are widely used to prove authenticity however these usually rely on an internet connection to be tamperproof. digital cam- eras o en don’t have an internet connection and when they do there’s no guarantee it will be operating due to network coverage issues.
Keywords: Memristor; offline hashchain; proof of authenticity; digital forensics
