Image Encryption based on Inter-pixel Displacement

In this era of technological advancements, to avoid the misuse of confidential information and misuse by the unauthorized access the authors need an encryption approach for security of image data. Here they proposed an algorithm which breaks the pixel into constituents i.e. red, green and blue are scattered to spatial space of image so that, basic property of pixel lost and difficult to reform the original image unless each of RGB component are located and identified. This paper discusses different methods of pixel displacement like chaotic method, bit shifting and inter-pixel displacement but focuses mainly on algorithms based on inter-pixel displacement.
