A security-based steganographic scheme in vector quantization coding between correlated neighboring blocks

摘要

With the growth of the Internet and the advancements in modern communication systems, sending data over the Internet or other media is now a commonplace practice. Consequently, it has become an important issue to secure the confidentiality and integrity of data because the data are sent via the Internet as a primary method of communication. This paper proposes a steganographic method based on the vector quantization coding compression algorithm with elastic indicators, which also incorporates a keystream to enhance security. Our experimental results have shown that the proposed method performs more effectively compared to the method proposed by Lee et al. in 2013.
