A High Secured Steganalysis Using QVDHC Model

Data compression plays a vital role in data security as it saves memory, transfer speed is high, easy to handle and secure. Mainly the techniques are categorized into two types. They lossless, lossy compression. The format will be an audio, image, text or video. main objective save memory of using these preserve confidentiality, integrity. In this paper, hybrid approach was proposed which combines Quotient Value Difference (QVD) with Huffman coding. These methods more efficient, simple implement provides better data. secret message encoded coding, while cover image compressed QVD. Then embedded transferred over network receiver. At receiver end, decompressed obtain original message. method shows high level performance when compared other existing quality minimum error.
