Abstract

Aiming at the problem of low hidden capacity and poor imperceptibility of the existing image information hiding algorithm in encrypted domain, an improved encrypted domain information hiding algorithm based on PVD (Pixel Valued Differencing) is proposed. The algorithm combines PVD algorithm, the logistic sequence is used to scramble the encrypted plaintext image, then the pixels in the encrypted image are paired, and the secret information is embedded according to the characteristic of the difference between the pixels. At the same time, the steganographic key is introduced to reduce the modification range of the pixel while keeping the hidden capacity. Experiments show that the algorithm has large hidden capacity, and under different embedding conditions, the imperceptibility of the improved algorithm is improved to some extent compared with the original PVD algorithm.
