- Abstract
A large-capacity information hiding algorithm for HEVC is proposed. We modify the intra prediction modes in 4x4 luminance blocks to embed secret information. According to the probability distribution of the statistical optimal prediction mode and suboptimal prediction mode, we are establishing a mapping relationship between prediction modes and secret information. Modifying the intra prediction modes to embed secret information is based on the mapping. The extraction of information merely requires decoding the prediction mode from the bit stream. Experimental results show that the proposed hiding algorithm can embed information with large capacity and effectively guarantee the subjective and objective quality of video.
