High Efficiency Reversible Data Hiding for Two-stage Vector Quantization Compressed Images
Data hiding is a booming technique aiming to embed secret data into digital media for content authentication, annotation or copyright protection. Reversible data hiding is a special type of data hiding technique that guarantees the host digital media can be losslessly recovered after the secret data are correctly extracted. In the past several years, some reversible data hiding schemes for Vect...
متن کاملA Survey of Reversible Data Hiding for VQ-Compressed Images
Data hiding has been popular over the past decades, and many different methods of the data hiding have been proposed. Nowadays, data hiding in compressed images becomes more and more popular because of the rise of the social media. Thus, we survey the previous research of data hiding of compressed images to provide the representative methods and analyze their capacities and bit rates. Finally, ...
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 کاملInformation hiding based on search-order coding for VQ indices
Compared with various information-hiding techniques on the spatial domain proposed previously, VQ-based information hiding technique has not been paid much attention. As a result, we present a steganographic scheme based on the search-order coding (SOC) compression method of vector quantization (VQ) indices in this paper. The major goal is to embed secret data into the compression codes of the ...
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...
