Validation of Forensic Crime Scene Images Using Watermarking and Cryptographic Blockchain

Abstract

Images are critical part of investigations, they are referred to and regarded, to gather information, document and create “memory” of a crime scene. Crime scene images are considered as vital criminal evidence in the court of law; hence, it is imperative that the authenticity of such images be maintained and that they be verifiable. The advancement in technology in this digitally proliferated era allows for easy doctoring of crime scene images. Digital watermarking, and blockchain have been used in other research works to authenticate and verify digital content or digital documents. In this paper we propose the use of watermarking and cryptographic blockchain to validate forensic crime scene images.
