Health is one of the issues that present more challenges in the world. These challenges not only come from the requirements of the region itself yet in addition result from outside conditions that impact individuals’ health conditions and access to therapeutic administrations. To augment the security strength of real-time healthcare applications in the IoT environment, a novel framework, namely, an Enhanced and IoT-based medical healthcare security scheme (EIMSS), has been proposed in this chapter. The proposed EIMSS adapts the AUP authentication technique proposed in the previous chapter for authentication while transferring the patient’s data. The proposed EIMSS approach offers flexible services to aged people like confidentiality, integrity, and authentication for protecting their vital biological and medical data. The simulation results, analysis and comparison confirm that the proposed EIMSS outperforms existing protocols with improved security strength.

A robust finger detection based sign language recognition using pattern recognition techniques

Subin M. Varghese, K. Aravinthan — Wed, 16 Oct 2024 00:00:00 +0000

Sign language recognition based on finger detection is arguably the main sign language used by most dumb people. It has its own phonetics, grammar and syntax that set it apart from other sign languages. Research related to sign language (SL) is only now becoming standardized. Considering the challenge of recognizing SL, in this work a new method for recognizing SL dynamic gestures is proposed. Sign language (SL) translation systems can be used to help dumb people interact with normal people with the help of a computer. Most studies on continuous recognition of sign language are done by processing frames obtained from videos at regular/equal intervals. If a developed system is powerful enough to handle both static and dynamic motions, then it will be the best system for processing frames obtained from processing consecutive gestures. The algorithm developed for the gesture recognition system in SL formulates a vision-based approach using two-dimensional discrete sinusoidal transforms (DSTs) for image compression and self-organizing maps (SOMs), or self-organizing feature maps. Kohonen’s (SOFM) Neural Networks for Pattern Recognition, simulated in MATLAB. The system showed an accuracy rate of 91 percent.

A. Tamilmani, K. Muthuramalingam — Wed, 16 Oct 2024 00:00:00 +0000

Crop type classification is a fundamental task in precision agriculture, enabling informed decision-making for crop management and resource allocation. Support vector machines (SVMs) have emerged as robust and effective tools for multiclass classification tasks. This study explores the application of SVM-based multiclass classification techniques to accurately categorize various crop types based on remote sensing data. The SVM algorithm is employed to create decision boundaries that maximize the margin between different crop classes while minimizing classification errors. To enhance classification performance, various kernel functions such as linear, polynomial, and radial basis functions are evaluated to capture complex relationships within the data. The proposed SVM-based approach is compared with other commonly used classification methods to assess its superiority in terms of accuracy, precision, recall, and F1 score.

This literature review investigates information literacy competency (ILC) among scholars in coeducational and women’s colleges, exploring the disparities, influencing factors, and educational impacts within these distinct academic settings. Information literacy, a critical skill for navigating the digital era, empowers students to evaluate, access, and utilize information effectively. This review synthesizes findings from diverse studies, comparing ILC levels between scholars in coeducational and women’s colleges and considering variables such as academic discipline, institutional resources, and the pedagogical environment. Research indicates that while coeducational institutions provide a broader range of resources and peer interactions, women’s colleges often emphasize collaborative and inclusive pedagogies that may enhance ILC. However, disparities in competency levels persist due to variations in information literacy training and institutional support structures. This review identifies key areas where ILC training could be improved, particularly through targeted interventions tailored to the needs of each educational setting. The findings underscore the need for comprehensive information literacy programs to equip scholars with essential competencies, ultimately fostering academic success and lifelong learning across diverse educational contexts.

Fuzzy optimization trust aware clustering approach for the detection of malicious node in the wireless sensor networks

A. Rukmani, C. Jayanthi — Wed, 16 Oct 2024 00:00:00 +0000

Wireless sensor networks (WSNs) are pivotal in various applications, ranging from environmental monitoring to military operations. However, their susceptibility to security threats, particularly from malicious nodes, poses significant challenges to network integrity and data reliability. This paper proposes an innovative methodology that integrates clustering with an optimization approach to effectively identify and mitigate malicious nodes in WSNs. In the proposed methodology, the network is divided into clusters, each managed by a cluster head responsible for monitoring the behavior of nodes within its cluster. Trust values are assigned to nodes based on parameters such as data forwarding accuracy, communication consistency, and energy consumption. These trust metrics are optimized using a sophisticated optimization algorithm, which fine-tunes the decision-making process for identifying malicious nodes. By leveraging clustering, the method efficiently distributes computational tasks, while the optimization algorithm enhances the accuracy of malicious node detection by dynamically adjusting trust thresholds. The approach not only reduces the incidence of false positives but also extends the network lifetime by preventing compromised nodes from disrupting network operations. This trust-aware, optimized clustering strategy offers a robust solution for securing WSNs in critical applications, ensuring reliable and secure data transmission across the network.
