Over recent years, the volume of big data has drastically increased for medical applications. Such data are shared by cloud providers for storage and further processing. Medical images contain sensitive information, and these images are shared with healthcare workers, patients, and, in some scenarios, researchers for diagnostic and study purposes. However, the security of these images in the transfer process is extremely important, especially after the COVID-19 pandemic. This paper proposes a secure watermarking algorithm, termed WatMIF, based on multimodal medical image fusion. The proposed algorithm consists of three major parts: the encryption of the host media, the fusion of multimodal medical images, and the embedding and extraction of the fused mark. We encrypt the host media with a key-based encryption scheme. Then, a nonsubsampled contourlet transform (NSCT)-based fusion scheme is employed to fuse the magnetic resonance imaging (MRI) and computed tomography (CT) scan images to generate the fused mark image. Furthermore, the encrypted host media conceals the fused watermark using redundant discrete wavelet transform (RDWT) and randomised singular value decomposition (RSVD). Finally, denoising convolutional neural network (DnCNN) is used to improve the robustness of the WatMIF algorithm. The simulation experiments on two standard datasets were used to evaluate the algorithm in terms of invisibility, robustness, and security. When compared with the existing algorithms, the robustness is improved by 20.14%. Overall, the implementation of proposed watermarking for hiding fused marks and efficient encryption improved the identity verification, invisibility, robustness and security criteria in our WatMIF algorithm.

“…To demonstrate the effectiveness of the proposed method, experiments have been conducted on different test images. The average embedding rate for all test images is 2.36 bpp, which shows that this method is able to embed high payloads compared to other methods [4]. Khani A aims to bridge the gap between frequency-based and schedule-based bus allocation models and proposes a routing algorithm with random vehicle arrival times to simulate the adaptive behavior of users in response to unreliable services.…”

With the continuous development and popularization of computer network applications, various ideas, theories, technologies and products related to the network emerge in an endless stream. The application of network in many fields such as industrial control, commercial activities, and daily life is becoming more and more frequent, and its role is becoming increasingly important. The purpose of this paper is to research and implement the technology of adding distributed system equipment based on the message passing algorithm, and propose a receiver scheme that introduces parallel computing in the clustered message passing algorithm (CMPA), optimizes the pruning rule and iterative update rule. According to the idea of reducing the number of iterations of the edge message passing algorithm (PM-MPA), a method is proposed by verifying that the confidence information of a certain codeword is much larger than that of other codewords. When the number of iterations of the receiver is reduced, the video monitoring equipment is added to the distributed system, and the remote and multi-point network video monitoring of the scene is realized. Through the simulation results, it can be found that Max-Log PMPA can reduce the complexity of Max-Log MPA by 65% when the overload rate is 200%. Therefore, when the overload is high, the advantages of Max-Log PMPA parallelism are even greater.

“…Recently, many RDH schemes based on the interpolated cover image were proposed [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ], which can embed more secret data than traditional RDH methods while preserving a good visual quality of confidential images. The interpolation-based RDH scheme is especially useful for the application of medical image management.…”

How to hide messages in digital images so that messages cannot be discovered and tampered with is a compelling topic in the research area of cybersecurity. The interpolation-based reversible data hiding (RDH) scheme is especially useful for the application of medical image management. The biometric information of patients acquired by biosensors is embedded into an interpolated medical image for the purpose of authentication. The proposed scheme classifies pixel blocks into complex and smooth ones according to each block’s dynamic range of pixel values. For a complex block, the minimum-neighbor (MN) interpolation followed by DIM embedding is applied, where DIM denotes the difference between the block’s interpolated pixel values and the maximum pixel values. For a smooth block, the block mean (BM) interpolation is followed by a prediction error histogram (PEH) embedding and a difference expansion (DE) embedding is applied. Compared with previous methods, this adaptive strategy ensures low distortion due to embedding for smooth blocks while it provides a good payload for complex blocks. Our scheme is suitable for both medical and general images. Experimental results confirm the effectiveness of the proposed scheme. Performance comparisons with state-of-the-art schemes are also given. The peak signal to noise ratio (PSNR) of the proposed scheme is 10.32 dB higher than the relevant works in the best case.
