Evil Twin Attacks on Smart Home IoT Devices for Visually Impaired Users
Securing the Internet of Things (IoT) devices in a smart home has become inevitable due to the recent surge in the use of smart devices by the visually impaired. The visually impaired users rely heavily on these IoT devices and assistive technologies for guidance, medical usage, mobility help, voice recognition, news feeds and emergency communications. However, cyber attackers are deploying Evil Twin and Man-in-the-middle (MITM) attacks, among others, to penetrate the network, establish rogue Wi-Fi access points and trick victims into connecting to it, leading to interceptions, manipulation, exploitation, compromising the smart devices and taking command and control. The paper aims to explore the Evil Twin attack on smart devices and provide mitigating techniques to improve privacy and trust. The novelty contribution of the paper is three-fold: First, we identify the various IoT device vulnerabilities and attacks. We consider the state-of-the-art IoT cyberattacks on Smart TVs, Smart Door Lock, and cameras. Secondly, we created a virtual environment using Kali Linux (Raspberry Pi) and NetGear r7000 as the home router for our testbed. We deployed an Evil Twin attack to penetrate the network to identify the vulnerable spots on the IoT devices. We consider the Kill Chain attack approach for the attack pattern. Finally, we recommend a security mechanism in a table to improve security, privacy and trust. Our results show how vulnerabilities in smart home appliances are susceptible to attacks. We have recommended mitigation techniques to enhance the security for visually impaired users
Effects of Cyberattacks on Virtual Reality and Augmented Reality Technologies for People with Disabilities
Virtual Reality (VR) and Augmented Reality (AR) technologies offer transformative solutions for individuals with disabilities, empowering them with enhanced accessibility and immersive experiences. The importance of VR and AR for accessibility provides assistive solutions for disabled users through accessibility enhancements, personalized assistive technologies to support education, rehabilitation support, and social inclusion and empathy building. However, limitations and security challenges are inherent in the current integration of VR and AR. That includes inadequate authentication, insecure communication channels, software errors, device incompatibilities, keystroke errors on controllers, poor network speed, and cyberattacks, potentially jeopardising vulnerable users' safety and well-being. The paper explores the impact of cyberattacks on VR and AR technologies for disabled users. The novelty contribution of the paper is threefold. First, we analyze existing VR and AR technologies and their immersive environments, including their vulnerabilities. Secondly, we consider the various cyberattacks being deployed to exploit the vulnerabilities in the settings and their impact on users with disabilities. Finally, we implement an attack to exploit a vulnerability in the AR and VR environment to determine security and recommend control mechanisms. The paper raises awareness of the importance of securing VR and AR to safeguard the inclusivity and independence of disabled users
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
