Abstract: In this work we propose an efficient and easily implemented codec system, which we named WaterIMAGE, for watermarking images that are intended for uploading on the web and making them public online. An important fact of our system is that it suggests a way in which an integer number can be represented in a two dimensional grid and, thus, since images are two dimensional objects that representation can be efficiently marked on them. In particular, our system uses an efficient technique which is based on a 2D representation of self-inverting permutations and mainly consists of two components: the first component contains an encoding algorithm which encodes an integer w into a self-inverting permutation p∗ and a decoding algorithm which extracts the integer w from p∗, while the second component contains codec algorithms which are responsible for embedding a watermark into an image I, resulting the image Iw, and extract it from Iw. Our system incorporates important properties which allow us to successfully extract the watermark w from the image Iw even if the input image has been compressed with a lossy method and/or rotated. All the system’s algorithms have been developed and tested in JAVA programming environment. (More)
