Chaos-based encryption for digital images and videos

Many digital services, such as pay TV, confidential videoconferencing, medical and military imaging systems, require reliable security in storage and transmission of digital images and videos. Because of the rapid progress of the Internet in the digital world today, the security of digital images and videos has become more and more important. In recent years, more and more consumer electronic services and devices, such as mobile phones and personal digital assistant (PDA), have also started to provide additional functions of saving and exchanging multimedia messages. The prevalence of multimedia technology in our society has promoted digital images and videos to play a more significant role than the traditional dull texts, which demands a serious protection of users’ privacy. To fulfill such security and privacy needs in various applications, encryption of images and videos is very important to frustrate malicious attacks from unauthorized parties.
