Implementation of Recursive method in Image Steganography

University essay from Blekinge Tekniska Högskola/Inst. för tillämpad signalbehandling, TISB

Abstract: Nowadays steganographic techniques are with us and in everywhere because we are using information more and more and we need to have or transform the information as secure as possible. In these techniques we need to secure the information by encrypting (coding) and decrypting (decoding). In this thesis we propose a different coding procedure based on recursive methodology. We used image as medium for this steganographic technique. An image is splitted (coded) and merged (decoded) by recursive procedure. Our experiments show that the technique is applicable for both Gray Scale and Color images and also no need of providing a key security facility at the decoder end.
