Color image quantum steganography scheme and circuit design based on DWT+DCT+SVD

Abstract

This paper presents a new steganographic algorithm for quantum color images, which utilizes DWT+DCT+SVD embedding technology. Firstly, in order to improve the security of secret information, a novel three-dimensional hyperchaotic system that combines the Chebyshev map and ICMIC map using a closed-loop coupling method (3D-CICC) is proposed. In addition, this paper proposes a new steganography algorithm based on DWT+DCT+SVD, which can effectively hide the secret image in the carrier image without being detected. At the same time, an efficient quantum circuit for quantum steganography is designed. The simulation and numerical analysis results show that the algorithm has good performance in invisibility analysis, security analysis, and robustness analysis.
