An Efficient Lossless Data Hiding Scheme on VQ Index Coding

Loss less data hiding can extract the embedded secret data and restore the cover media to its original status. Wang et al. in 2010 proposed a loss less data hiding method to embed secret message on VQ indices but their scheme has the encoded bit stream over-expanded. This paper improves their embedd...

Summary:Loss less data hiding can extract the embedded secret data and restore the cover media to its original status. Wang et al. in 2010 proposed a loss less data hiding method to embed secret message on VQ indices but their scheme has the encoded bit stream over-expanded. This paper improves their embedding approach by employing the index clusters with localization to enhance the similarity of adjacent indices and to improve the compressing code strem arrangement for effectively reducing the bit rates of final code stream.
