Abstract

Based on the randomness and disorder of three-dimensional image, a hidden image information is encrypted by three-dimensional chaotic scrambling. Then, the encrypted information is embedded into the three-dimensional image by two-dimensional discrete Fourier transform. Without changing the original visual effect of the image, a good hiding effect is achieved. The experimental results show that the algorithm can effectively resist strong external attacks, has good robustness, and has a certain practical value.
