Remote Attestation of Software and Execution-Environment in Modern Machines
2015
The research on network security concentrates mainly on securing the communication channels between two endpoints, which is insufficient if the authenticity of one of the endpoints cannot be determined with certainty. Previously presented methods that allow one endpoint, the authentication authority, to authenticate another remote machine. These methods are inadequate for modern machines that have multiple processors, introduce virtualization extensions, have a greater variety of side effects, and suffer from nondeterminism. This paper addresses the advances of modern machines with respect to the method presented by Kennell. The authors describe how a remote attestation procedure, involving…
Anomaly detection approach to keystroke dynamics based user authentication
2017
Keystroke dynamics is one of the authentication mechanisms which uses natural typing pattern of a user for identification. In this work, we introduced Dependence Clustering based approach to user authentication using keystroke dynamics. In addition, we applied a k-NN-based approach that demonstrated strong results. Most of the existing approaches use only genuine users data for training and validation. We designed a cross validation procedure with artificially generated impostor samples that improves the learning process yet allows fair comparison to previous works. We evaluated the methods using the CMU keystroke dynamics benchmark dataset. Both proposed approaches outperformed the previou…
Using a mobile application to support children's writing motivation
2013
PurposeThe purpose of this paper is to explore the use of the prototype of a mobile application for the enhancement of children's motivation for writing. The results are explored from students' and experts' perspectives.Design/methodology/approachThis study is based on a field trial and expert evaluations of a prototype of a mobile application. The field trial data consists of questionnaire data collected from elementary school students (n=25) who used the mobile prototype. The expert evaluations (n=8) of the prototype were conducted based on usability and pedagogical heuristics. The main research question is how the mobile application motivates children to learn creative writing.FindingsTh…
Design principles for collaboration platforms for open education
2015
Increasing the current low uptake of Open Education Resources (OER) is a key challenge for researchers and practitioners in the field. User studies have shown that collaboration is a main success factor for successful open educational activities. However, effective collaboration in open educational contexts requires well planned processes and platforms supporting collaboration, in particular in physically distributed settings. We have been investigating the value of such platforms, their main features and user requirements to enable collaboration from immature ideas to completed resources. We used quantitative and qualitative research methods to collect insights from potential users of such…
Teaching Knowledge Management by Combining Wikis and Screen Capture Videos
2011
PurposeThis paper aims to report on the design and creation of a knowledge management course aimed at facilitating student creation and use of social interactive learning tools for enhanced learning.Design/methodology/approachThe era of social media and web 2.0 has enabled a bottom‐up collaborative approach and new ways to publish work on the web, promoted by tools such as YouTube video service. In this spirit a knowledge management course was designed aiming to facilitate university students to compose videos on different difficult concepts in the theory part of the course by searching for explanations on the web and by creating a Windows Media Player video focusing on the self‐defined pro…
Developing cloud business models: A case study on cloud gaming
2011
Cloud computing offers new ways for firms to operate in the global market so that even small firms can compete in markets traditionally dominated by multinational corporations. A case study considers how, over ten years, a small firm developed a successful business model to compete in computer gaming. peerReviewed
SearchBot: Supporting voice conversations with proactive search
2018
Searching during conversations and social interactions is becoming increasingly common. Although searching could be helpful for solving arguments, building common ground, and reinforcing mutual assumptions, it can also cause inter-actional problems. Proactive search approaches can enrich conversations with additional information without neglecting the shared and established social norms of being attentive to ongoing interaction. This demo showcases SearchBot, a tool that minimizes the issues associated with the practice of searching during conversations. It accomplishes this by tracking conversational background speech and then providing continuous recommendations of related documents and e…
Adaptive framework for network traffic classification using dimensionality reduction and clustering
2012
Information security has become a very important topic especially during the last years. Web services are becoming more complex and dynamic. This offers new possibilities for attackers to exploit vulnerabilities by inputting malicious queries or code. However, these attack attempts are often recorded in server logs. Analyzing these logs could be a way to detect intrusions either periodically or in real time. We propose a framework that preprocesses and analyzes these log files. HTTP queries are transformed to numerical matrices using n-gram analysis. The dimensionality of these matrices is reduced using principal component analysis and diffusion map methodology. Abnormal log lines can then …

Is My Office 365 GDPR Compliant? : Security Issues in Authentication and Administration
2018
The General Data Protection Regulation, commonly referred as GDPR, will be enforced in all European Union countries in May 2018. GDPR sets requirements for processing EU citizens’ personal data regardless of the physical location of the organisation processing the data. Over 40 percent of European organisations are using Office 365. Microsoft claims that Office 365 service is GDPR compliant, and has provided tools to help Office 365 customers to ensure their GDPR compliancy. In this paper, we present some security issues related to the very foundation of Office 365 service, namely Azure Active Directory and administrative tools, and assess their GDPR compliancy. Our findings reveal that per…
