Behavior of multiple data hiding techniques towards noisy channels

Data Embedding is an art of concealing information of high significance or secrecy inside an image or video sequence. Numerous techniques are being researched to develop a strong and optimized algorithm to embed the data so as to withstand aggressive operations done on it and to extract the vital piece of information embedded into it. The proposed work is focused towards studying the behavior of multiple data embedding techniques subjected to noisy channels thus providing the user to select an optimal embedding technique to establish a tradeoff between the level of invisibility and robustness to external attacks. The invisibility criteria are determined in terms of embedding and scaling parameters and the robustness of the watermark is tested with respect to its ability to withstand channel noise.
