- Abstract
With the development of high-speed networks, life is more convenient than ever. However, the information security issue of high-speed networks is still a big problem. As an important branch of information security, steganography is a useful method to protect confidential information. In this paper, by combining the trailing coefficient produced in the process of the quantization of the H.264 encoding standard with the current video steganographic algorithms, we implement a new kind of algorithm based on trailing coefficients. The algorithm firstly conducts a DCT transform on the frame, and then it obtains the trailing coefficient for each quantized DCT block; lastly, the secret information bit is embedded into the video. The experimental result indicates that this algorithm has little influence on video quality and has a large capacity of steganography; also, it has a strong anti-steganalysis capability and high robustness.
