Abstract

This paper discusses about the comparative study between spatial and transform domain multimedia data hiding for communication purpose. Still image watermarking can't be used for real time communication. That's why our key objective directs towards the packet communication through still image watermarking. Since still image data hiding technique generally shows low data embedding rate or payload, it is tried to remove that problem also. Moreover, the proposed scheme has to be such one, which can minimize the co-channel interference thereby extracting the multimedia contents with lowest possible error. Based on this analysis, Zigzag modulation and RGB spatial domain and Discrete Cosine Transformed (DCT) domain techniques are proposed which shows better visual and statistical invisibility.
