As the ubiquity of Android devices continues to grow, the importance of safeguarding user data and privacy within the Android app ecosystem becomes increasingly critical. Central to this security framework is the permission-based security model, which grants users control over the extent to which apps access sensitive device resources and personal information. This paper provides a thorough examination of the efficiency of permission-based security models in Android applications, furnishing valuable perspectives on the everchanging realm of security. At the core of Android's security framework lies the permission-based security model, a system designed to regulate an app's access to sensitive device resources such as the camera, microphone, location, contacts, and personal data. This model empowers users by granting them the authority to approve or deny these permissions when installing or using an app, ostensibly ensuring the privacy and security of their data. This review embarks on a comprehensive exploration of the effectiveness of permission-based security models in Android apps. In the context of the permission-based model, it explored potential security vulnerabilities and the real- world risks they pose to users devices and data. The performance of different malware detection systems associated with the permission based android apps and its limitations are also analyzed in this paper. By synthesizing existing research and empirical evidence, this paper provides valuable insights into the current state of permission-based security in Android apps and suggests directions for future research and development. © 2024 IEEE.

The cellular automaton (CA), a discrete model, is gaining popularity in simulations and scientific exploration across various domains, including cryptography, error-correcting codes, VLSI design and test pattern generation. This paper examines a two-state three-neighborhood nonuniform finite CA with a specified number of fixed points. We utilize a graph-based tool known as the next state rule minterm transition diagram (NSRTD) to analyze the spatiotemporal behavior of these cellular automata (CAs) across all lengths. We devise methods for synthesizing nonuniform single length cycle multi-attractor CAs (MACAs), a specialized class of irreversible CA with a predefined number of fixed points for any arbitrary length. Despite the method’s exponential worstcase time complexity, it offers the advantage of selecting rules for each CA cell from a set of candidate rules, ensuring the desired number of fixed points. © 2025, Complex Systems Publications, Inc.

Federated Adversarial Learning (FAL) maintains the decentralization of adversarial training for data-driven innovations while allowing the collaborative training of a common model to protect privacy facilities. Before sharing with bigger global aggregation, it allows users to change settings locally over many iterations. However, a strong network against attackers in Industry 5.0 towards consumer digital ecosystems is a challenge for adversarial training methodologies. To solve this issue, a novel FAL-based Customized Inequality-Aware Federated Learning (CusIAFL) technique is proposed in this paper for classifying and securing color images. The proposed method reduces the instability brought on by the heterogeneity of the data and optimizes each data sample by understanding the client-label distribution. A unique Pix2Pix Generative Adversarial Network (GAN) algorithm is employed to generate realistic images in the presented research work, while a hybrid approach is used to guarantee consistency in the time series data. This innovative research work is evaluated on various non-medical, consumer electronic, and medical imagery. The experimental results have been evaluated using performance metrics, namely accuracy, entropy, Peak Signal-to-Noise Ratio (PSNR), Hausdorff Distance (HD95), Structural Similarity Index (SSIM), and Mean Square Error (MSE). The results show that the proposed technique outperforms the existing models in terms of security. © 1975-2011 IEEE.

Purpose: The rapid spread of COVID-19 has resulted in significant harm and impacted tens of millions of people globally. In order to prevent the transmission of the virus, individuals often wear masks as a protective measure for themselves and others. Coronavirus protection guidelines have been published by the World Health Organization (WHO). According to WHO standards, COVID-19 can be prevented by wearing a mask in public places and congested regions. In these places, it is very difficult to personally check to see if people are wearing face masks or not. Methods: The objective of this research work is to build a powerful, efficient, and real-time approach for detecting people not wearing masks. Three cutting-edge object identification models, namely YOLOv4, Tiny-YOLOv4, and YOLOv5, are employed in this study for the identification of masked faces. Result: The proposed YOLOv5 model is evaluated using real-time images captured using a smartphone or tablet. The test images include both single and multiple people with and without masks. The YOLOv5 model achieved recognition accuracy of 88.90% with an average detection speed of 0.0316 s per image, whereas the YOLOv4 and Tiny-YOLOv4 produced recognition accuracy of 82.24% and 74.80% with an average detection speed of 0.0530 s and 0.0541 s per image, respectively. Conclusion: The comparative performance suggests that the YOLOv5 model has a maximum recognition accuracy of 88.90% in face mask identification tasks compared to other models such as the YOLOv4 and Tiny-YOLOv4. © The Author(s), under exclusive licence to The Brazilian Society of Biomedical engineering 2025.

Strategies to Selecting Most Profitable Products by Price Settings

International Journal of Information Technology and Decision Making 2024年第2期23卷 885-915页

For a company, it is important to know which products to launch to the market that may get the maximal profit. To achieve this goal, companies not only need to consider these products' features, but also need to analyze how customers make their purchase decisions. For most customers, the price of a product is the most important purchase factor. If the price of a product can be adjusted, the purchase decision of a customer may change. With different price settings, we can speculate on the expected number of customers and the profit of the products. Motivated by this, we want to find the most profitable products among the candidates for the company. A distance-based adoption model can be used to evaluate the expected customers for products at different prices. The computational cost is high in two parts. One is the computational cost of obtaining the most profitable information on each set of candidate products. Another part is that many candidate product combinations need to be calculated. To tackle the computation problem, we propose two strategies. One is to avoid considering all possible price settings. The other is to avoid processing all possible subsets of the candidate products. Experimental results reveal the efficiency of our strategies. © 2024 World Scientific. All rights reserved.

Recommendation systems are crucial components of modern digital platforms, enhancing user experience and driving engagement by providing personalized suggestions. Traditional recommendation models, such as collaborative filtering and content-based filtering, have been widely adopted but face significant challenges, including the cold-start problem, data sparsity, and limited interpretability. Recent advancements have explored the use of knowledge graphs (KGs) and neural networks to address these limitations. Knowledge graphs provide a rich semantic framework for representing user and item relationships, thereby enhancing the recommendation quality by uncovering latent connections. Neural networks, particularly deep learning models, have demonstrated their capability to learn complex patterns from large datasets, resulting in improved recommendation accuracy and personalization. This survey provides a comprehensive overview of the integration of knowledge graphs and neural networks in recommendation systems. It reviews the evolution of recommendation models, from traditional methods to more sophisticated approaches that leverage KGs and neural architectures, such as Graph Neural Networks (GNNs) and Neural Collaborative Filtering (NCF). The paper compares these models based on scalability, accuracy, interpretability, and computational complexity. It identifies key research gaps, including scalability issues, dynamic adaptation of KGs, and privacy concerns, and outlines future research directions to address these challenges. By exploring novel hybrid approaches that combine the strengths of knowledge graphs and neural networks, this survey aims to advance the development of more robust, explainable, and scalable recommendation systems. © 2025 IEEE.
