Abstract—An information hiding algorithm for HEVC is proposed. For 33 kinds of directional prediction modes in the encoding process of 4×4 luminance blocks, intra prediction modes are mapped to the angle values. We are establishing a mapping relationship table between the angle differences 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 little influence on the bit-rate and effectively guarantee the quality of the cover video.

Index Terms—Information hiding, HEVC, intra prediction, angle differences.
