Data Hiding and Retrieval on Image Using MSB Encoding Technique

This paper proposes a technique in which we use a distributed source encoding on encrypted images for hiding the data. Reversible data hiding is technique in which data in the cover image can reversibly retrieved after extracting the hidden data .Here we encrypt the image using stream cipher. After the series of bits is selected, the data hider compresses this selected bits using Slepian-Wolf encoding. If the receiver has embedding key as well as encryption key, only then the original data and image is recovered perfectly using distributed source decoding.
