Due to the rapid growth of digital communication and multimedia application, security becomes an important issue of communication and storage of images. Image security has found a great need in many applications where the information (in the form of image) is to be protected from unauthorized access. Encryption is one of the ways to ensure high security. In recent years, encryption technology h...

—Multimedia information availability has increased dramatically with the advent of mobile devices. But with this availability comes problems of maintaining the security of information that is displayed in public. Many approaches have been used or proposed for providing security for information dissemination over networks, protection system classified with more specific as encryption information...

Lately, multimedia encryption has been the focus of attention in many researches. Recently, a large number of encryption algorithms has been presented to protect image contents.The main objective of modern image encryption schemes is to reduce the computation complexity in order to respond to the real time multimedia and/or limited resources requirements without degrading the high level of secu...

Secure multimedia communication presents new challenges that are difficult to handle by using the currently adopted encryption methods. Chaotic encryption is a new direction of cryptography. It uses chaotic system properties such as sensitivity to initial condition and loss of information. In order to reach higher performance, these methods take advantage of the more and more complex behavior o...

The huge availability of multimedia data on the internet makes the creation, modification and distribution of the multimedia content easy and affordable. This improvement in the digital techniques has led a path to unauthorized access, copying and distribution of multimedia data, which throws a serious challenge in the field of copyright protection. This paper focuses on providing security and ...

Wireless multimedia sensor networks will play a central role in the Internet of Things world, providing content-rich information for an uncountable number of monitoring and control scenarios. As more applications rely on multimedia data, security concerns gain attention, and new approaches arise to provide security for such networks. However, the usual resource constraints of processing, memory...

IEEE SIGNAL PROCESSING MAGAZINE 50 MARCH 2004 ecuring the exchange of intellectual property and providing protection to multimedia contents in distribution systems have enabled the advent of digital rights management (DRM) systems [5], [14], [21], [47], [51], [53]. Rights holders should be able to license, monitor, and track the usage of rights in a dynamic digital trading environment, especial...
