Abstract :
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 data encryption optimization is proposed. Secondly, a general-purpose lightweight speed adjustable video encryption scheme is given. Thirdly, a series of selective encryption control models and their solution algorithms are proposed. Experimental analyses show the performances of the presented schemes are effective enough to support real-time multimedia sensing applications.
