Enforcing mobile security with location-aware role-based access control

2013

This paper describes how location-aware role-based access control RBAC can be implemented on top of the Geospatial eXtensible Access Control Markup Language GeoXACML. It furthermore sketches how spatial separation of duty constraints both static and dynamic can be implemented using GeoXACML on top of the XACML RBAC profile. The solution uses physical addressing of geographical locations, which facilitates easy deployment of authorisation profiles to the mobile device. Location-aware RBAC can be used to implement location-dependent access control and also other security enhancing solutions on mobile devices, such as location-dependent device locking, firewall, intrusion prevention or payment…

Acceptance of E-Learning Devices by Dental Students

2013

Background: E-Learning programs and their corresponding devices are increasingly employed to educate dental students during their clinical training. Objective: Recent progress made in the development of e-learning software as well as in hardware (computers, tablet PCs, smartphones) caused us to more closely investigate into the habits of dental students in dealing with these learning techniques. Methods: Dental students during their clinical training attended a survey compiled in cooperation with biostatisticians. The questionnaire probands were asked to complete based on previous surveys of similar subjects, allowing single as well as multiple answers. The data, which were obtained with re…

A Comparison of the User Experiences of Primary Care Electronic Health Record Systems

2020

Digital health records play an important role for the information flow in primary care organizations that carry out services at patient’s home. Mobile digital solutions have improved the access to up-dated care information at the patient’s home, facilitating new ways for clinical workflow and care delivery. This paper presents a study comparing the user experiences of two electronic health record systems in two primary care organizations in Norway. Qualitative research methods were applied with interviews and observations made between 2017 and 2019 where clinical end-users of primary care electronic health records participated. The study showed that the systems had an important function for…

Modelling Mobile Encounter Networks

2006

This article presents mobile encounter networks, which emerge when mobile devices come across each other and form a temporary connection between them using a common short-range radio technology. Local information exchanges between mobile devices results in a broadcast diffusion of information to other users of the network with a delay. In addition to presenting the concept of mobile encounter networks, we also provide an abstract method for describing the information diffusion process inside them. peerReviewed

Mobile Search - Social Network Search Using Mobile Devices Demonstration

2008

Mobile search prototype demonstrates the possibilities of social network search in N800 mobile devices. Search is initiated from a N800 mobile device to search the contacts in mobile device's addressbook. The contacts can be other N800 mobile devices running mobile Web server or normal Web servers in the Internet with Drupal content management system. Mobile device users can select which of their personal information such as phone numbers, calendar data etc. to share via a mobile Web server. The proposed search mechanism has many benefits compared to centralized Web search engines like Google. The search can locate information which is not referenced anywhere and thus allows hidden or rare …

Mobile Encounter Networks and Their Applications

2008

This article presents mobile encounter networks (MENs), which emerge when mobile devices come across each other and form a temporary connection between them using a common short-range radio technology. Local information exchanges between mobile devices results in a broadcast diffusion of information to other users of the network with a delay. Gasoline price comparison system (GPCS), which delivers newest gasoline prices to mobile users using mobile encounter information diffusion, is described as well as other application areas where MENs could be used. The feasibility of building MENs using bluetooth is tested with the BlueCheese mobile encounter network middleware and it is found that the…

Information Exchange in Mobile Encounter Network

2007

In this paper we analyze an information exchange method based on information diffusion in mobile encounter networks, a form of mobile peer-to-peer networks. We utilize dual mobility model which provides support for more realistic simulations compared to mobility models based only one method of movement. The distribution of the mobile device encounter intervals are discussed and analyzed via simulation runs. The logistic model is suggested to provide reasonably accurate estimates of the information diffusion process.

2018

Smartphones and other mobile devices have fundamentally changed patterns of Internet use in everyday life by making online access constantly available. The present paper offers a theoretical explication and empirical assessment of the concept of online vigilance, referring to users' permanent cognitive orientation towards online content and communication as well as their disposition to exploit these options constantly. Based on four studies, a validated and reliable self-report measure of online vigilance was developed. In combination, the results suggest that the Online Vigilance Scale (OVS) shows a stable factor structure in various contexts and user populations and provides future work i…

The Screen Is Yours—Comparing Handheld Pairing Techniques for Public Displays

2013

Whereas mobile devices have been heavily investigated as remote controls for distant displays, research on the fundamental first step, the pairing with the display, is scarce. In a comparative user study with 31 participants we evaluated five potential pairing techniques concerning their performance and acceptance for connecting to a public display and gained insights into the general requirements for pairing techniques in this special usage context. Besides four established mobile interaction techniques (touching an NFC tag, capturing a QR code, scanning, and manual input), our study considered a recent appropriate pairing technique called display pointing, which allows passers-by to conne…
