VQ Coding in Data Hiding Using Correlated Neighboring Blocks in Security Performance

摘要

With the continued expansion of the Internet and increased means of communication, it is inevitable that we send data via the Internet or other such media. The important issue of maintaining the confidentiality and integrity of such data when using the Internet as a primary mode of communication also continues to grow in scale. In this paper, we therefore propose an information-hiding method based on the vector quantization (VQ) compression algorithm with elastic indicators; further, we present our design for a key stream to enhance security. Our experimental results have shown that our proposed method performs better as compared to the method introduced by Lee et al. in 2013.
