Hybrid Matrix Coding and Error-correction Coding Scheme for Reversible Data Hiding in Binary Vq Index Codestream

In this paper, we propose a novel reversible data hiding framework to hide secret data into a binary codestream of VQ indices invertibly, in which matrix encoding is used to efficiently embed secret data, and error correction coding (ECC) is employed for lossless restoration of the marked codestream at the receiver side. Due to the unchanged structure of the codestream during the embedding process, our scheme can significantly improve the security of our scheme. The use of ECC, however, leads to a decreased compression ratio. As a lossless compression method for VQ index tables, search-order coding is used as a remedy to improve the compression performance. According to the experimental results, it is testified that the proposed scheme achieves a high stego-image quality, a large embedding capacity, a high transmission efficiency and an acceptable compression performance. Moreover, our scheme achieves the relatively high performance in terms of the security.
