| Abstract: | A rise in data transmission rates and other security issues have resulted from the Internet's dramatic rise in popularity. Compressing and encrypting data at the same time is essential for the secure transfer of multimedia content, such as digital photographs. The development of compression methods in combination with strong encryption methods in hybrid combinations like chaotic mapping has helped alleviate this issue. In this work, blocked DCT and chaotic maps (Arnold and Logistic maps) are used to compress and encrypt the medical images respectively in hybrid combination for safe and lightweight transmission. We demonstrated how to reduce the size of the original medical image by employing the blocked discrete cosine transform. The compressed image is then encrypted using Arnold and a logistic map. We have shown experimentally that the hybrid system employed significantly improves the majority of the metrics used to evaluate a system's performance, including PSNR, SSIM, NPCR, UACI, and the correlation coefficient. Through cryptanalysis, it is proven that the proposed crypto system is secure against differential and statistical assaults. The proposed cryptographic system is suitable for use in telehealth applications. |
