A Novel Image Encryption Optimization Technique

Abstract

Abstract— Image file confidentiality is a difficult issue these days for a variety of reasons in a range of industries, including medical, defence, academia, and many more. A range of practical ways have been studied in recent years to safeguard image data, however owing to technological improvements, such existing solutions have significant limits in current systems. Several academics have investigated a number of methodologies and strategies for maintaining picture secrecy and shielding top-secret information from attackers while images are sent via communications infrastructure. In this paper, an unique picture encryption technique based on a chaotic map and DNA encoding is jointly used for image encryption in a more pragmatic approach, as necessary in today's world to safeguard private data. This approach was tried and confirmed on a personal laptop with a 64-bit operating system, Windows 10, with 16 GB RAM and the MATLAB R2020a version loaded (Random Access Memory). The results of this suggested approach reflect the best NPCR (Number of Pixel Change Rate) and UACI (Unified Average Changed Intensity) scores for a variety of selected photos for testing. This method works with a variety of image formats and is in great demand in today's world for safeguarding sensitive data or information while being transmitted across a communications infrastructure. More research is needed in the future to identify practical answers, as current communication networks are quickly changing throughout the world owing to technology breakthroughs.
