Research On Quantum Image Steganography Protocol Based On Efficient Codin

Steganography is always an important branch of information hiding technology,which can protect the safe transmission of secret information,such as military information,commercial information transmission and so on,and has important practical significance.In the past,classical steganography was mainly used to protect the safe transmission of information.However,with the continuous development and breakthrough of artificial intelligence technology and quantum technology in recent years,classical steganography is facing increasing risks and challenges.Therefore,it is necessary to design steganography protocols that can resist future quantum computers’ attacks,so this paper makes use of the characteristics of quantum images and the advantages of classical coding to analyze and design the steganography protocol of quantum images with high embedding efficiency and good imperceptibility.The specific research contents are as follows:(1)A novel quantum EMD(exploiting modification direction)steganography protocol is proposed to improve the shortcoming of quantum EMD steganography protocol.The new methods of expanding modification range and dynamically sharing between subgroups are introduced in the new protocol.The former makes many bits in pixel modified surface modifications,improves the embedding capacity,which can effectively compress the redundant imperceptibility of the pixels in the group,not only to further improve the capacity,and improve the efficiency of embedded and embedding rate.At the same time,the simulation results show that the new protocol still has good imperceptibility.(2)Based on classical matrix coding scheme and ZZW(Zhang Weimin,Zhang Xinpeng and Wang Shuozhong)steganography framework,two new efficient steganography protocols for quantum images are proposed.The first protocol quantized ZZW steganography framework,combined with the advantages of the original framework and quantum state,so that the new protocol not only has high security,but also greatly improves the embedding efficiency of the existing quantum image steganography protocol.However,the capacity is low.The second protocol is an improvement on the first,doubling its capacity and once again improving the embedding efficiency.Simulation results show that both protocols have good imperceptibility.(3)Based on quantum image expansion technology and Grover search algorithm,a more secure and large-capacity steganography protocol for quantum images is proposed.The new protocol encodes the secret information at three levels and at the same time encrypts it at three levels.Finally,the secret information is transmitted through the quantum channel in the form of quantum state,which has very high security.At the same time,the quantum image expansion technology enables the new protocol to transmit multiple images,and its capacity is much larger than the known quantum image steganography protocol,which is conducive to the information transmission scene of large-scale data.
