Edge detection steganography and quantum circuit design based on a novel fractal chaotic system

A quantum image steganography algorithm based on edge detection is proposed. Firstly, a new fractal chaotic system with good chaotic properties is proposed to improve the security of the secret information. In addition, this study creates a new steganography algorithm with edge detection. By finding as many edge points in the image as possible through edge detection, the secret information is embedded in non-edge locations, which greatly improves the security and invisibility of the algorithm. Meanwhile, an efficient and secure quantum steganographic circuit is designed. The results of simulation experiments and numerical analysis show that the algorithm is securely complete and invisible and also has good robustness.
