There exists a problem that data is less reliable when some security acci-dents occur, which is attributed to the changeable monitoring data in the process of secure production in the mines. To cope with this problem, a data sharing model to monitor the security of mines based on the blockchain. At the same time, a Practical Byzantine Fault Tolerant Algorithm(PBFT) based on credit points is proposed to improve the consensus efficiency and security of the algorithm in the consortium chain. Using the improved EigenTrust credit model can play a dynamic role in evaluating the reliability of nodes, simplifying the consistency protocol, and making the system stable and secure. The experimental results show that the improved algorithm significantly improves the throughput and transaction speed, so compared with other models, the proposed blockchain-based coal mine safety monitoring data sharing model shows better optimization performance. © 2022 Taiwan Ubiquitous Information CO LTD.

For location information publishing, its sparsity can seriously affect the effectiveness of traditional location differential privacy protection algorithms. In this paper, a user interest-based differential privacy location publishing algorithm combined with quadtree partition (QPDPLP) is proposed, which uses a mapping function to process perturbed locations outside the user’s area of interest to reduce the amount of noise injection. First, the disturbance location of the user interest area is combined with the quadtree structure to divide. Second, the ratio of each node weight to the total weight is the basis for area division, and then according to the sparsity of the divided area position points to add noise to the area position points. Finally, using the real location and the processed disturbance location of the randomly selected location as a published location. Experimental results show that, given the same privacy budget, the QPDPLP algorithm is more effective than traditional algorithms in protecting users’ location privacy. © 2022, Taiwan Ubiquitous Information CO LTD.

Aiming at the low localization accuracy of wireless sensor network (WSN) nodes with large-scale low-density anchor nodes, a three-dimensional localization algorithm for WSN nodes that mix RSSI and DV-Hop is proposed. Firstly, the genetic tabu numerical optimization hybrid algorithm (GANV) is proposed to solve the problems that the numerical optimization algorithm is easy to fall into local optimum solution, and the genetic tabu algorithm has poor local searchability to obtain the global optimization solution. Secondly, RSSI ranging technology is introduced into the node location part of the DV-Hop algorithm combined with RSSI, and the GANV algorithm solves the initial value. Finally, in the RSSI location algorithm combined with DV-Hop, the location problem of each node is reduced to an unconstrained nonlinear non-convex optimization problem. After the initial value is input, it is solved by the GANV algorithm, and the location estimation is obtained after eliminating outliers by the clustering algorithm. Simulation results show that compared with the traditional node location algorithm in WSN, this algorithm has high location accuracy and is very suitable for large-scale WSN engineering applications with low real-time requirements and high location accuracy requirements. © 2022, Journal of Network Intelligence.

With the rapid development of mobile devices, rapid positioning has become one of the most popular services in mobile online social networks. In the fast location service, users can enjoy a better social experience by updating their real-time location information. However, the accuracy of the query results and the leakage of personal information may hinder the further development of the service. Hence, a location privacy protection method based on feature generalization is proposed for the existing problems. In this method, an algorithm called dynamic clustering is constructed to improve the con-struction efficiency of clusters in the anonymous region and simultaneously enable each cluster to meet the needs of K anonymity. Then, using the captain election algorithm and query algorithm, while meeting the user’s mobility and flexible privacy protection requirements, accurate query results can be quickly returned to the user. Through the-oretical analysis and experiments, it is verified that this method is a safe and effective privacy protection solution. © 2022 ISSN 2414-8105 (Online).

In the process of data cleaning, there are problems of high difficulty and low efficiency for processing IIS (incomplete information system) that has large size data. As this problem, distributed IMR (DIMR) is a method with data preprocessing capability for distributed IIS. We propose a distributed extended rough set of graph structure (DRSG) based on DIMR using Spark to accelerate parallel processing of IIS under big data. Specifically, we introduce the concepts of reliable element and controversial element, and establish a connection through non-symmetric similarity relation. Then, a graph structure with hierarchical relationship is proposed. And the path from the reliable element to the controversial element replaces the block in DIMR to calculate the approximation set. Finally, a parallel algorithm is proposed and the experiments show that DRSG reduces the resources required for computing and improves the speed in Spark. A comparative analysis has been conducted comprehensively to assess the performance of the proposed algorithm with DIMR on 8 datasets. And the results show that DRSG has faster speed. And the dependency is similar to or higher than DIMR. © 2023 IEEE.
