An improved reversible information hiding scheme for Encrypted Video

In order to solve the problem of low capacity of reversible data hiding (RDH) in encrypted video, an improved histogram translation method is proposed to achieve large capacity. A two-dimensional histogram of motion vector difference was constructed and a histogram translation algorithm with high utilization rate was designed to realize reversible information hiding in encrypted video. The experimental results show that the embedding capacity of the scheme is increased by 153.3% on average, the average PSNR of encrypted video is less than 15.956 dB, and the average PSNR of decrypted stego video can reach more than 30 dB.
