The multimedia big data in multimedia sensing and other IoT (Internet of Things) systems are high-volume, real-time, dynamic and heterogeneous. These characteristics lead to new challenges of data security. When computation and power resources in some IoT nodes are very scarce, these challenges become more serious that complex data security process on multimedia data is restricted by the aforementioned...
Video and audio streams in large-scale multimedia sensing system are high-volume, while computation and power resources are very scarce, which restricts the usage of complex data security process on multimedia data. Therefore, the confidentiality of video data under resources constraints is studied in this paper. Firstly, the trend of resources constraints is discussed, and an analysis model for multimedia...
