Abstract :
This paper proposes a crypto-compression scheme to protect the distribution and storage of digital medical images. The proposed process uses a chaotic system in order to provide an efficient digital medical images encryption. This enhanced scheme combines between compression based on DCT and encryption. Simulation experiment, sensitivity and statistical analyses have validated the effectiveness of the proposed system.
