Abstract

Currently, research is focused on selective encryption to protect movies against attacks transmitted over a public network. This choice is taken to ensure the security of compressed data without adding an important supplemental computational time for the encryption. So the encryption module is inserted into the video compression chain. In this paper we present an encryption method based chaos inserted in the H.264/AVC chain specially for the motion vectors signs. The results will be deducted according to the values of PSNR (Peak Signal to Noise Ratio), SSIM (Structural SIMilarity) and the encryption rate. Motion vectors signs encryption (MVSE) seems being interesting to lose the visual quality of the video for Inter predicted frames since movies are sensible to the motion sign.
