Hiding Information in VQ Index Tables with Reversibility
نویسندگان
چکیده
In this paper, we propose a simple and efficient reversible information-hiding scheme for VQ index tables. One secret bit can be embedded into one index pair if this pair passes the predefined restriction. Even if the index pair does not pass the test, it can still carry one secret bit if an additional indicator (a preserved index value) is attached. The experimental results show that our proposed schemes can accomplish lossless recovery of VQ index tables, and the hiding capacity is satisfactory.

متن کاملHuffman-code strategies to improve MFCVQ-based reversible data hiding for VQ indexes
Data hiding, which embeds secret data into cover media, is one type of technology used to achieve the multimedia security. A reversible data hiding method has the characteristic that the cover media can be completely reconstructed after secret data are extracted. Recently, some reversible data hiding schemes have focused on the vector quantization (VQ)-compressed format. Using the modified fast...
متن کاملLossless Data Hiding Based on Improved Vq Index Joint Neighboring Coding
Data hiding is a form of steganography to embed secret data into digital media for the purpose of content authentication, annotation and copyright protection. Lossless data hiding is a special kind of data hiding technique that guarantees the digital media can be losslessly restored after the secret data are correctly extracted. In the past several years, several reversible data hiding schemes ...
متن کاملLossless Information Hiding in the VQ Index Table
In this paper, a reversible data hiding scheme based on a Vector Quantization (VQ) index table is proposed. To satisfy different needs of users, our proposed scheme is designed with flexibility in adjusting hiding capacity and compression rate. First, the codebook is rearranged referring to the index occurrence frequency in the VQ index table. After that, the codewords in the newly generated co...
متن کاملHybrid 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 proc...
