Ensuring privacy in a Distributed Video Coding surveillance scenario

In this paper, a permutation scheme is introduced for Distributed Video Coding. The main goal is to preserve privacy and security in video surveillance video communications and can be adapted for other scenarios. The proposed approach consists to apply permutation based encryption to the DVC scenario. The permutation is defined by a secret key which is required at the decoder for decompression providing security. Simulation results show that the reference architecture and the permutation-based proposed have similar rate distortion performance.
