A scrambling approach is a method which is employed on almost all commercially manufactured system including image and video systems.In this paper, we proposed a new scrambling approach which uses random process.We first separate blocks into certain size, and relocated them randomly.This is block shuffling which is proposed for the purpose of randomizing the block location.The relocated blocks have three channels, R, G, and B, and each color channel's luminance values are complemented.Experimental results show that the proposed method well-protect contents.
