A HEVC Video Steganography Algorithm Based on 8×8 QDCT Coefficients

HEVC is an efficient video encoding standard that can provide better video quality and lower bit rates. Therefore, HEVC videos are widely used in high-definition/ultra-high-definition video applications, video conferencing, live streaming, and other fields. Therefore, steganography algorithms using HEVC videos as carriers have high transmission concealment. This paper proposed a HEVC video steganography algorithm based on intra-frame 8×8 QDCT coefficients. An effective embedding scheme was used to improve the visual quality of the algorithm, and the performance of the algorithm was demonstrated through experiments.
