A lossless image encryption technique using chaotic map and DNA encoding
摘要
Image encryption is required to protect digital images from unauthorized access and tampering. With the increasing use of digital images in various fields such as medical imaging, military imaging, and e-commerce, it has become essential to secure the transmission and storage of these images. In this paper, we propose a new image encryption technique that uses a combination of Deoxyribo Nucleic Acid (DNA) encoding and chaotic maps. The proposed technique aims to provide a high level of security for digital images while also maintaining low computational complexity. The encryption process involves encoding the image data using DNA sequences and then performing a chaotic map transformation on the encoded data. The resulting cipher image is highly resistant to attacks such as brute-force and statistical analyses, making it suitable for secure transmission and storage. We evaluate the effectiveness of our proposed technique by comparing it with other popular encryption methods using various performance metrics. The results show that our approach outperforms other methods in terms of security and computational efficiency. For instance, we achieved Number of Pixel Change Rate (NPCR) of 99%, correlation coefficient in order of
