High-capacity Reversible Data Hiding for Encrypted Videos Based on Multi-domain Embedding

Aiming at the problem that the embedding capacity of reversible data hiding in encrypted videos is not high, a high-capacity reversible data hiding scheme in encrypted videos based on multi-domain embedding is proposed. First, the flow cipher is used to encrypt the signs of the quantize discrete cosine transforms coefficient and the motion vector difference to form two ciphertext fields. Then the information is embedded in QDCT and MVD, respectively, using different histogram panning methods. Experimental results show that the peak signal-to-noise ratio(PSNR) of encrypted video is not more than 15dB, and the PSNR of stego video is maintained at more than 30dB, and the embedding capacity is increased by up to 24.3%.
