Abstract

How to better protect the copyright of quantum images is an important research subject in quantum watermarking technology. Based on the representation of quantum log-polar images, this paper proposed a novel quantum watermarking algorithm. According to the value of the key shared by the both communicating parties, the sender selected one of the high four qubits of the pixel gray value of quantum carrier image as the controlled qubit. And it embedded the watermarking information into the least significant qubit or the peripheral least significant qubit of quantum carrier image on the basis of the value of the selected controlled qubit. Utilizing the key to implement the controlled least significant qubit modification technique improved the transparency and robustness of quantum watermark image. Experimental simulation and performance analysis based on MATLAB show that the new algorithm has a good performance on transparency, robustness and the embedding capacity.
