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.
