Abstract

Covert transmission technology is a new direction in the field of information security technology. It can protect copyright and authentication sources and integrity in an open network environment, and ensure the security of digital media content through information hiding technology. Some unique features of screen content video have promoted the further development of video coding technology, and the HEVC-SCC standard has emerged as the times require. It is of great significance and value to study the information security issues of screen content coding standards. Therefore, based on the unique characteristics of the SCC stream, this paper studies the information steganography technology, and uses the video information hiding technology to transmit private data. A video steganography scheme based on chaotic mapping in DCT domain is proposed where the proposed method applies to HEVC screen content coding. The mutation frame of the screen content sequence is judged according to the threshold value, and the location of the secret data embedding is shuffled and scrambled based on the value of the chaotic logistic map digital chaotic sequence, thereby improving the security.
