As the internet and multimedia systems grow in size and popularity, compression and encryption of image and video data are becoming increasingly important. However, independent compression and encryption is too slow for many multimedia applications. This paper presents a new joint compression and encryption method for images and videos that uses high-order conditional entropy coding of wavelet coefficients to facilitate encryption. As a result, state-of-the-art compression and significantly enhanced security are achieved, with no extra computational complexity.
