Abstract
Multimedia audio, video, and images have dominated the Internet traffic and also constituted the major applications in our daily life. Multimedia security has always been a concern in the community due to the issues of movie and music piracy, and privacy of medical images. Conventional cryptography can be applied to multimedia but additional challenges, such as real-time and efficiency, must be addressed. With emerging multimedia applications such as peer-to-peer streaming, and 3D data, multimedia is embracing a big data era where security and privacy are facing new challenges. Most multimedia security surveys have focused on the aspect of issues related to data communication. In the big data era, cloud computing is becoming a major platform which needs attracting due attention in the multimedia community. This keynote speech will provide a report on the advances in the field and open research questions will be discussed. The focus will be placed on efficient algorithms for emerging multimedia applications such a 3D imaging, and cloud based applications including digital rights management.
