“…The spatial domain-based watermarking algorithms directly modify the pixels of the host image to embed the watermark. One classical algorithm is the least significant bit algorithm (LSB) [8,22], which is simple, but it is less robust to most attacks. The frequency domainbased watermarking algorithms embed the watermark by modifying the frequency domain coefficients of the host image.…”

In this paper, we develop a robust image zero-watermarking algorithm based on multiple circular statistical features. First of all, we detect stable feature points from the host image, and construct circular region partitions from the identified feature points, which contain the critical information of the host image. Second, the statistics and differences of circular region partitions are calculated, which contain both the local differences and the global information of the host image. Third, we apply discrete cosine transform (DCT) and singular value decomposition (SVD) in statistics and differences in order to construct the feature image. The stability of DCT and SVD further warrants the robustness of the algorithm. Moreover, Arnold transform is used to scramble the watermark image to enhance the security of the algorithm. Finally, we obtain the zero watermark by performing the exclusive-or (XOR) operation between the feature image and the scrambled watermark image, and the zero watermark is stored in the copyright authentication database for copyright authentication. Moreover, to combat geometric attacks, we develop a blind image correction algorithm without using the original image to accurately correct the attacked image. Numerous experiments and comparisons with the state-of-the-art (SOTA) watermarking algorithms confirm that the proposed algorithm affords good robustness against various attacks, such as filtering attacks, noise attacks, geometric attacks, and even a random combination of the above-stated attacks.

“…Digital watermarking, i.e. the process of insertion and extraction of the watermark, can be carried out either in spatial [9][10] or in frequency / transform domain [11][12][13], although some hybrid logics [14][15] have also been developed to get a better result.…”

“…This information hiding scheme is applicable for all types of multimedia objects, and hence by the type of the cover object, watermarking can be classified as text [16], image [9][10][11][12][13][14], audio [17], and video [15]. As per the scope of this paper, image watermarking is the prime concern.…”

Telemedicine is one of the most eminent terms used in the modern e-healthcare system. Digital medical image reports, along with electronic patient records, play a central role in diagnosis from distance. These reports need to be transmitted over an open communication channel with immense security and reliability, so that appropriate diagnosis can be performed. Moreover, the privacy of the patient is required to be preserved. Digital watermarking is one of the most conventional and suitable practices to serve all of these purposes. New challenges appear in the domain of watermarking with the advancement of digital signal processing; consequently, researchers are endowing more efforts to overcome these challenges. In this paper, a survey on medical image watermarking has been done, and the performance of a few state-of-the-art medical image watermarking techniques is compared. This work makes the researchers and the developers familiar with the recent trends, challenges, and scopes in this domain to facilitate them in finding out adequate research directions.

“…A new approach uses entropy measures to detect key player sets within a social network, providing a simple solution to the KPP-Pos problem [30]. Entropy-based measures are employed to identify the key player sets, but the shortcoming of such methods is that they are limited to nondense heterogeneous networks [31][32][33].…”

Smart grid construction provides the basic conditions for grid connection of renewable energy power generation. However, the grid connection of large-scale intermittent renewable energy sources increases the complexity of operational control of power systems. With the increase in intermittent renewable energy grid connections, distribution system operators must optimize and integrate these new participants to ensure the flexibility and stability of smart grids. Dividing the smart grid into logical clusters helps to overcome the problems caused by intermittent renewable energy grid connections. In this study, we propose a 2-step modeling approach that includes both link and leverage analyses to detect the network partitioning and assess the stability of the smart grids. Our experimental results of the link analysis show that, despite the identical scores in modularity and Silhouette Coefficients (SC), the total computational time of the linear programming model for linkage (CD1) is 29.8% shorter than that of the quadratic programming model for linkage (CD2) on 7 networks with fewer than 200 nodes, whereas CD2 is 29.5% faster than CD1 on 19 larger networks with more than 200 nodes. The leverage results of benchmark networks indicate that the computational time of each instance with the proposed linear programming model for leverage (ID1) and quadratic programming model for leverage (ID2) was substantially reduced, and the Critical Node Problem (CNP) results of mediumand large-scale networks were better than those reported in the literature, which play a significant role in smart grid optimization.INDEX TERMS Intermittent renewable energy, smart grid, link analysis, leverage analysis, grid partitions I.
