Konferensbidrag (refereegranskat)abstract
- The Internet of Things (IoT) market is growing rapidly, allowing continuous evolution of new technologies. Alongside this development, most IoT devices are easy to compromise, as security is often not a prioritized characteristic. This paper proposes a novel IoT Security Model (IoTSM) that can be used by organizations to formulate and implement a strategy for developing end-to-end IoT security. IoTSM is grounded by the Software Assurance Maturity Model (SAMM) framework, however it expands it with new security practices and empirical data gathered from IoT practitioners. Moreover, we generalize the model into a conceptual framework. This approach allows the formal analysis for security in general and evaluates an organization’s security practices. Overall, our proposed approach can help researchers, practitioners, and IoT organizations, to discourse about IoT security from an end-to-end perspective.

Accessibility in Web Development Courses : A Case Study
- 2020
-
Ingår i: Informatics. - Basel, Switzerland : MDPI. - 2227-9709. ; 7:1

Tidskriftsartikel (refereegranskat)abstract
- Web accessibility is becoming a relevant topic with an increased number of people with disabilities and the elderly using the web. Numerous legislations are being passed that require the web to be universally accessible to all people, regardless of their abilities and age. Despite this trend, university curricula still teach traditional web development without addressing accessibility as a topic. To investigate this matter closely, we studied the syllabi of web development courses at one university to evaluate whether the topic of accessibility was taught there. Additionally, we conducted a survey with nineteen students who were enrolled in a web development course, and we interviewed three lecturers from the same university. Our findings suggest that the topic of accessibility is not covered in web development courses, although both students and lecturers think that it should. This generates lack of competence in accessibility. The findings also confirm the finding of previous studies that, among web developers, there is a low familiarity with accessibility guidelines and policies. An interesting finding we uncovered was that gender affects the motivation to learn about accessibility. Females were driven by personal reasons, which we attribute to females having an increased sense of empathy. Finally, our participants were divided in their opinions whether accessibility contributes to usability.

Konferensbidrag (refereegranskat)abstract
- At the time when we are debating the Internet as a human right, an access to basic online information is a challenge for blind and visually impaired community. Steps taken for their digital inclusion, such as, the Web Content Accessibility Guidelines (WCAG) are often insufficient. In this paper we present initial requirements gathered during three workshops organized with various stakeholders coming from three different countries. Initial results suggest that the context of use and the cultural dimension play a crucial role in making digital content accessible for this community. Additionally, a one-solution-fits-all model is inadequate without considering levels of visual impairment when providing customized web and mobile experience. Finally, we lay out challenges that with comprehensive requirements gathering in the future, could address various problems that blind and visually impaired face.

Augmenting requirements gathering for people with special needs using IoT : a position paper
- 2016

Ingår i: Proceedings of the 9th International Workshop on Cooperative and Human Aspects of Software Engineering. - New York, NY, USA : ACM Digital Library. ; , s. 48-51, s. 48-51

Konferensbidrag (refereegranskat)abstract
- Requirements gathering are an important aspect of application development, especially when users are people with special needs. Traditionally, this process is being conducted using conventional methods, such as interviews, workshops and questionnaires. These approaches, however, are unable to grasp the full context when collecting data from the communities of people with special needs, mainly because of the difficult access to participants and incomprehensiveness of the data gathered. To mitigate such issues, in this position paper, we argue that existing traditional methods could be complemented by means of Internet of Things. The immense amount of data gathered from various devices interconnected could help generate meaningful data that will complement the usually insufficient amount collected using traditional methods. This new approach is, however, associated with challenges that are discussed along with a possible scenario on how data complementing from traditional and the indirect method could be done.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Access to web content continues to be a challenge for the visually impaired, as the needs of such community are very diverse. The access is further hindered by the fact that designers continue to build websites non-compliant with Web Content Accessibility Guidelines (WCAG). To better understand the needs of the visually impaired community, three workshops were organized with various stakeholders coming from three different countries. The results from the workshops suggest that one-solution-fits-all model is inadequate without considering the levels of visual impairment when providing customized web experience. A set of requirements devised from the workshops guided the process of building a middleware prototype. Using eight adaptation techniques, the prototype provides the required user experience based on users level of visual impairment. Preliminary evaluation of the middleware suggests that several adaptation techniques perform better with non-WCAG compliant websites compared to those being compliant.

Human Factors for Cybersecurity Awareness in a Remote Work Environment
- 2023
-
Ingår i: ICISSP 2023 - Proceedings of the 9th International Conference on Information Systems Security and Privacy. - : SCITEPRESS - Science and Technology Publications. - 2184-4356. - 9789897586248 ; , s. 608-616
-
Konferensbidrag (refereegranskat)abstract
- The conveniences of remote work are various, but a surge in cyberthreats has heavily affected the optimal processes of organizations. As a result, employees' cybersecurity awareness was jeopardized, prompting organizations to require improvement of cybersecurity processes at all levels. This paper explores which cybersecurity aspects are more relevant and/or relatable for remote working employees. A qualitative approach via interviews is used to collect experiences and perspectives from employees in different organizations. The results show that human factors, such as trust in cybersecurity infrastructure, previous practices, training, security fatigue, and improvements with gamification, are core to supporting the success of a cybersecurity program in a remote work environment.

Hacking a Commercial Drone with Open-Source Software : Exploring Data Privacy Violations
- 2021
-
Ingår i: 2021 10th Mediterranean Conference on Embedded Computing (MECO). - : IEEE. - 9781665439121 ; , s. 1-5
-
Konferensbidrag (refereegranskat)abstract
- Drones have been discussed frequently in both governmental and commercial sectors for their normalization in the airspace. Nonetheless, drones bring diverse privacy concerns to users. In this paper, we explore the ramifications to data privacy from the perspective of drone owners. To investigate privacy in this context, four experiments targeting a commercial drone were conducted using open-source software. The experiments identified personal data (e.g., audio, video, and location) that are at risk of being compromised particularly through the execution of a basic deauthentication attack launched at a commercial drone. Our findings indicate the severity of risks affecting commercial drones. This makes the case for more effective privacy regulations and better guidelines suitable for securing drones.

- 2014
-
Ingår i: Educational Technology & Society. - 1176-3647 .- 1436-4522. ; 17:4, s. 316-334
-
Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study is to investigate the effects of a ubiquitous problem-based learning system (UPBLS) on students' question-raising performance in field inquiry activities. An experiment was conducted on an elementary school natural science course. A total of 43 sixth and fifth grade elementary students divided into experienced and novice groups participated in the field observation activities with on-line discussion over a period of seven months to evaluate the changes in their questioning ability. Moreover, a rubric for evaluating the students' questioning ability was developed and validated. Supported by UPBLS, the students collected the required wetland ecology data in three wetland field observation activities. The experimental results show that the students' questioning abilities significantly improved during the learning process. Moreover, it was found that both the experienced and the novice students had similar progress trends, implying that the proposed approach is helpful for improving the questioning abilities of students with different levels of prior knowledge.

Artificial Intelligence and Machine Learning Approaches in Digital Education : A Systematic Revision
- 2022
-
Ingår i: Information. - : MDPI. - 2078-2489. ; 13:4
-
Forskningsöversikt (refereegranskat)abstract
- The use of artificial intelligence and machine learning techniques across all disciplines has exploded in the past few years, with the ever-growing size of data and the changing needs of higher education, such as digital education. Similarly, online educational information systems have a huge amount of data related to students in digital education. This educational data can be used with artificial intelligence and machine learning techniques to improve digital education. This study makes two main contributions. First, the study follows a repeatable and objective process of exploring the literature. Second, the study outlines and explains the literature's themes related to the use of AI-based algorithms in digital education. The study findings present six themes related to the use of machines in digital education. The synthesized evidence in this study suggests that machine learning and deep learning algorithms are used in several themes of digital learning. These themes include using intelligent tutors, dropout predictions, performance predictions, adaptive and predictive learning and learning styles, analytics and group-based learning, and automation. artificial neural network and support vector machine algorithms appear to be utilized among all the identified themes, followed by random forest, decision tree, naive Bayes, and logistic regression algorithms.
