Abstract: The traffic of digital images and video has grown rapidly in the internet. Security becomes important for several applications like military image database, confidential video conferencing. Real-time secure image and video communication is challenging due to the processing time and computational requirement for encryption and decryption. Also the speed of most internet connections is very limited so the amount of data to be transmitted must be reduced. In this research, we shall introduce partial encryption technique on compressed images and videos. Another algorithm decomposes images into several different parts. We apply encryption algorithm to encrypt only the crucial parts, which are considerably smaller than original image, which result in significant reduction in processing time and computational requirement for encryption and decryption as well as reduce the bit rate and bandwidth requirement
