Fingerprint authentication has been extensively employed in contemporary identity verification systems owing to its rapidity and cost-effectiveness. Due to its widespread use, fingerprint leakage may cause sensitive information theft, enormous economic and personnel losses, and even a potential compromise of national security. As a fingerprint that can coincidentally match a specific proportion of the overall fingerprint population, MasterPrint rings the alarm bells for the security of fingerprint authentication. In this paper, we propose a new side-channel attack on the minutiae-based Automatic Fingerprint Identification System (AFIS), called PrintListener, which leverages users’ fingertip swiping actions on the screen to extract fingerprint pattern features (the first-level features) and synthesizes a stronger targeted PatternMasterPrint with potential second-level features. The attack scenario of PrintListener is extensive and covert. It only needs to record users’ fingertip friction sound and can be launched by leveraging a large number of social media platforms. Extensive experimental results in real-world scenarios show that Printlistener can significantly improve the attack potency of MasterPrint. © 2024, CC0.

cyberbullying represents one of the most recent challenges stemming from the widespread adoption of social media platforms. With the surge in social media usage, the right to express oneself is being misused. Statistics reveal that approximately 36.7% of individuals believe that they have encountered cyberbullying at some point in their lives. These figures have more than doubled since 2007, and a noticeable increase occurred from 2018 to 2019, indicating an unfavorable trend. While there are existing solutions in the market aimed at mitigating this issue, many of them come with usage limitations or employ fewer effective algorithms. The primary objective of this work is to explore innovative methods for comprehending and automatically identifying instances of cyberbullying across online text messages and comments on different social media platforms. For achieving this goal, real-time data are gathered, including comments, headlines and text messages from trending posts on twitter, and devised a labelling study for categorizing cyberbullying. An analysis is presented of this labelled data, which includes an examination of the relationships between various features and both cyberbullying and cyberaggression. The core focus of this work is the early detection of cyberbullying as it originates, while being drafted in real-time. The aim of this work is to enhance the efficiency of cyberbullying detection by using various machine learning techniques and natural language processing.

Integrating Battery Energy Storage Systems (BESSs), Supercapacitor (SCs) and Photovoltaic (PV) panels into Microgrid (MGs) increases reliability through energy regulation and stabilization. However, the acquisition cost of the device is rather high, and it has constant maintenance costs, which can lead to a higher total annual cost. Furthermore, the deterioration of these storage components over time affects both the ability of the systems and the overall cost. In an attempt to address these drawbacks, this manuscript presents an optimal operating strategy of MG system with HESS and PV. The proposed method is Supervised Attention Multi-Scale Temporal Convolutional Network or SAMTCN for short. The general objective of the proposed method is to minimize the TAC of the MG system and to enhance the overall performance of the system. The SAMTCN that is proposed in this paper is employed to forecast the energy demand and supply trends prevailing in the MG, in order to fully exploit the HESS and PV panels used. Through the precise projection of energy variations, SAMTCN minimizes wastage of energy, energy storage losses are avoided, and general system efficiency is enhanced. Then, the proposed technique is with implemented in MATLAB and compared with other techniques that have been put forward. The proposed method outperforms all existing approaches such as Artificial Neural Network (ANN), Improved Deep Neural Network (IDNN), Fuzzy Logic Control (FLC), Artificial Rabbits Optimized Neural Network (ARONN), and Multi-objective Artificial Hummingbird Algorithm (MOAHA). The results demonstrate that SAMTCN outperforms these methods, achieving a TAC of $132,270.8 and an efficiency of 99.7%. These outcomes confirm the superiority of SAMTCN in reducing costs and maximizing the efficiency of MG systems with HESS and PV panels. © 2024 IEEE.

Sparse inner product (SIP) has the attractive property of overhead being dominated by the intersection of inputs between parties, independent of the actual input size. It has intriguing prospects, especially for boosting machine learning on large-scale data, which are tangled with sparse data. In this paper, we investigate privacy-preserving SIP problems that have rarely been explored before. Specifically, we propose two concrete constructions, one requiring offline linear communication, which can be amortized across queries, while the other has sublinear overhead but relies on the more computationally expensive tool. Our approach exploits state-of-the-art cryptography tools including garbled Bloom filters (GBF) and Private Information Retrieval (PIR) as the cornerstone but carefully fuses them to obtain nontrivial overhead reductions. We provide formal security analysis of the proposed constructions and implement them into representative machine learning algorithms including k-nearest neighbors, naive Bayes classification, and logistic regression. Compared to existing efforts, our method achieves 2-50× speedup in runtime and up to 10× reduction in communication. © 2004-2012 IEEE. All rights reserved.

In the era of edge computing, securing data transmission has become paramount, especially given the real-time requirements and limited computational resources of edge devices. This study introduces a novel Chaos Theory-Based Lightweight Encryption Algorithm (CTBLEA) designed to enhance data protection in edge computing environments. The proposed algorithm leverages the inherent unpredictability of chaotic maps to secure data streams without imposing significant computational burdens. By adopting a lightweight encryption mechanism, CTBLEA ensures minimal latency and energy consumption, making it ideal for resource-constrained edge devices. Extensive experiments were conducted to evaluate the algorithm's performance. CTBLEA achieved an encryption and decryption time of 0.25 ms per kilobyte, showing a 35% reduction in latency compared to traditional AES encryption in similar environments. Furthermore, the algorithm demonstrated an energy consumption reduction of 40% while maintaining high security standards with an average key space of 10^l5, making brute-force attacks infeasible. security tests showed a correlation coefficient close to zero (0.003) between the original and encrypted data, indicating high randomness and minimal data correlation. Additionally, the algorithm's resistance to statistical and differential attacks was validated, with a 99.7% randomness score from the NIST suite tests. These results confirm the potential of CTBLEA for safeguarding real-time data in edge computing, offering a secure, efficient solution for next-generation loT and edge environments.

This study supports advanced materials by examining the properties of Al 7175 alloy reinforced with zirconium diboride (ZrB2) nanoparticles. Understanding and improving the wear resistance of composites is an important goal because it is essential for many industrial applications. Hence, in this research, Al 7175 alloy is reinforced with nanoparticles of ZrB2 at three different percentages. This research was carefully designed to investigate the connection between material (such as composition, load, speed and sliding distance) and response (such as friction force (FF), wear rate (Sf) and friction coefficient (Cf)). The optimal combinations for reducing Cf, Sf, and FF are found using Taguchi SNR analysis. The result was 5% content, 25.2 N load, 400 rpm speed, and 71.2 m drift. The confirmation test was done, and it shows that the obtained responses are optimized for the predicted optimal combinations. Also, an artificial neural network (ANN) model was developed to predict responses based on input data, another advancement that has helped data scientists. The ANN model performed well in the training, validation and testing phases, with an overall prediction rate of 87.873%. The research outcomes show that with the increase in composition percentage of the ZrB2 and the reduction in speed and load, the wear rate is minimal. Hence, the alloy Al 7175 reinforced with the nanoparticles of Zrb2 at 5% tends to reduce the wear rate and its friction coefficients. © 2024 IEEE.

cyber Threat Intelligence (CTI) is an actionable, evidence-based knowledge management system of cyber threats data. CTI consists of 3 (three) major parts, namely information gathering, analysis, and dissemination. To carry out dissemination in CTI, Structured Threat Information Expression (STIX) and Trusted Automated Exchange of Intelligence Information (TAXII) have been developed as open and interoperable standards for the CTI dissemination. An effective CTI is a CTI that can be integrated into the organization's security operations processes. Many organizations today runs CTI with a mechanism for reporting and distributing information in the dissemination process or known as cyber threat information sharing which has significant effects on security operations performance. In this study, user requirements analysis and design of cyber threat information sharing processes were carried out. From the results of the requirement analysis, a suitable business process re-engineering were proposed to accelerate the automation of CTI, especially in the information sharing part. Lastly, the designed processes were tested by simulating the processes using STIX and TAXII-based platform. The results of this study indicate that the designed processes can be run on STIX and TAXII-based platforms, ergo a step toward to a fully automated CTI. © 2021 IEEE.

Secure two-party comparison, known as Yao’s millionaires’ problem, has been a fundamental challenge in privacy-preserving compu-tation. It enables two parties to compare their inputs without revealing the exact values of those inputs or relying on any trusted third party. One elegant approach to secure computation is based on homomorphic encryption. Recently, building on this approach, Carlton et al. (CT-RSA 2018) and Bourse et al. (CT-RSA 2020) presented novel solutions for the problem of secure integer comparison. These protocols have demon-strated significantly improved performance compared to the well-known and frequently used DGK protocol (ACISP 2007 and Int. J. Appl. Cryp-togr. 1(4),323-324, 2009). In this paper, we introduce a class of higher residuosity attacks, which can be regarded as an extension of the clas-sical quadratic residuosity attack on the decisional Diffie-Hellman prob-lem. We demonstrate that the small RSA subgroup decision problems, upon which both the CEK and BST protocols are based, are not difficult to solve when the prime base p_0 p0 is small (e.g., $ p_0 © International Association for Cryptologic Research 2025.

Medical sensor network consists of an architecture in which medical sensor devices are implanted in human body to collect different types of sensitive data and share it on a network. These networks are connected with each other via wireless technology. Wireless medical sensor network (WMSN) came into existence with these medical sensor networks. Transmitted data from these WMSN's is then further processed in remotely located medical units. In the meanwhile, a registered medical professional of this network can access this information to rectify the patient's conditions via internet. This transmitted information is critical for the patient. It should be secured and private. It is very important to provide secure and private access to patient's data. Internet has an open infrastructure for every one as well as hackers whom can intrude such kind of sensitive information for their own benefits. It is a challenging issue for WMSNs to resist such kind of abrupt activity. A smaller number of protocols are being introduced in the literature, about WMSN, providing security and user authentication. Some of the protocols regarding WMSN are not standardized enough to provide user anonymity. This study is proposed to provide a protocol with potential to preserve user anonymity as well as mutual authentication for the mobile users. Precisely, this protocol is not only providing sufficient complexity but also robustness to security against unwanted threats. Moreover, it is providing a login phase, mutual authentication characteristics, and a phase to change the old password into a new one. © 2023 IEEE.
