Multimedia Security: Novel Steganography and Privacy Preserving
Security and Communication Networks
Multimedia security is not a new research topic, as there have been a large body of work on various aspects of multimedia security. However, there remain a number of open research challenges, partly due to advances in multimedia and other related consumer technologies, for example, threats to conventional steganography due to emerging machine/deep learning-based steganalysis approaches. Thus, there is a need to design steganography approaches to mitigate such steganalysis efforts. Another ongoing challenge is how to ensure the privacy of multimedia data and the processing of such data, given constant advances in computational capabilities and big data analytics. In this special issue, we aim to provide readers with a broad overview of multimedia security, such as novel steganography, privacy preserving on cloud computing, and multimedia tampering detection.
