Selective video encryption using chaotic system in the SHVC extension

Abstract : In this paper we investigate a selective video encryption in the scalable HEVC extension (SHVC). The SHVC extension encodes the video in several layers corresponding to different spatial and quality representations of the video. We propose a selective encryption solution using a chaotic-based encryption system. The proposed solution encrypts a set of sensitive parameters with a minimum complexity overhead, at constant bitrate and SHVC format compliant. Experimental results compare the performance of three encryption schemes: encrypt only the lowest layer, all layers, and only the highest layer. The first two schemes achieve a high security level with a drastic degradation in the decoded video, while the last scheme enables a perceptual video encryption by decreasing the quality of the highest layer below the quality of the clear layers.
