| 摘要: |
| 量子图像安全处理是一个新兴的研究领域，而量子图像数据隐藏是量子图像安全处理技术的一种，在不损害载体的情况下可用于保护量子图像的版权和认证量子图像是否完整。目前尚缺乏对量子图像可逆数据隐藏的详细技术研究。结合差值扩展技术，本文提出了一种量子图像可逆数据隐藏算法：1）选用NEQR量子图像表示法来表示图像；2）借鉴经典的差值扩展算法，在NEQR量子图像上对量子比特进行处理，可逆嵌入数据；3）设计了信息嵌入、信息提取和载体无损恢复的量子线路图，并进行了仿真。基于经典图像的实验结果表明，本文算法是可逆的，可用于将来对量子图像的认证和保护。 |

| Abstract: |
| Quantum image secure processing is a new research field and reversible data hiding in quantum image is an import issue in quantum image secure processing technologies, which can be used to protect copyright and integrity of quantum images. In literature, there is lack of reversible data hiding for quantum images. In this paper we propose a reversible data hiding algorithm by difference expansion. Firstly, NEQR is applied to store cover quantum image. Furthermore, the information is reversibly embedded into the cover quantum image by using classical deference expansion strategy. Quantum circuits of information embedding, information extraction and original quantum image's restoration are given in details. Simulation testing in classical way has shown that the proposed method is reversible, and can be used as a potential solution for protection of quantum images. |
