Incorporating Trust into Context-Aware Services

Enabling technologies concerning hardware, networking, and sensing have inspired the development of context-aware IT services. These adapt to the situation of the user, such that service provisioning is specific to his/her corresponding needs. We have seen successful applications of context-aware services in healthcare, well-being, and smart...

Toward a Reference Architecture for User-Oriented Open Government Data Portals

Governments have established Open Government Data Portals (OGDP) to open various types of datasets that can be used to increase transparency, accountability, and innovation. OGDP is becoming a strategic program for citizen engagement and empowering users. Nevertheless, many OGDP architectures focus merely on publishing data and do not support...

Combining Context-Awareness and Data Analytics in Support of Drone Technology

Drones performing an autonomous mission need to adapt to frequent changes in their environment. In other words, they have to be context-aware. Most current context-aware systems are designed to distinguish between situations that have been pre-defined in terms of anticipated situation types and corresponding desired behavior types. This only...

A Stakeholders Taxonomy for Opening Government Data Decision-Making

Stakeholders can have different views on the opening of data, and conflicts may arise between them. Several causes of disputes may arise during the decision-making process due to the diverse objectives, interests, and needs among the stakeholders that perceive their desires. Yet, no stakeholder taxonomy exists to guide this decision-making...

Improving Resilience Using Drones for Effective Monitoring after Disruptive Events

We observe a world of increasing anxiety due to natural and man-made disasters, pandemics, andmilitary conflicts. Such disruptive events lead to decreased infrastructure and personnel availability; still, infrastructure and personnel are essential for keeping society running, and for addressing the effects of disruptions. We argue that drone...

Making enterprise information systems resilient against disruptive events: a conceptual view

Enterprise Information Systems (EIS) are designed to deal with normal variability in their inputs and data. Empowered by CONTEXT-AWARENESS, some EIS even count on sensors and/or data analytics for capturing changes outside of the system. Nevertheless, context-awareness would often fail when EIS are affected by (large-scale) disruptive events,...

Stakeholder tensions in decision-making for opening government data

Various types of stakeholders are often involved in the process of deciding to open data. However, the influence of multiple–actors on the decision-making process is ill-understood. Stakeholders play different roles and have different interests in opening and analyzing datasets. The objective of this paper is to understand the influence of...

Ethical hacking for boosting IoT vulnerability management: A first look into bug bounty programs and responsible disclosure

The security of the Internet of Things (IoT) has attracted much attention due to the growing number of IoT-oriented security incidents. IoT hardware and software security vulnerabilities are exploited affecting many companies and persons. Since the causes of vulnerabilities go beyond pure technical measures, there is a pressing demand...

A Comparative Study of Methods for Deciding to Open Data

Governments may have their own business processes to decide to open data, which might be supported by decision-making tools. At the same time, analyzing potential benefits, costs, risks, and other effects-adverse of disclosing data are challenging. In the literature, there are various methods to analyze the potential advantages and...

Governance as a Condition for Creating Business Value from Enterprise Architecture

IT Governance is often viewed as an important factor for creating business value for firms. However, there is limited work investigating the relationship between architectural governance and the contributions of enterprise architecture (EA) to firm performance. Based on a study of more than 15 cases the analyzes shows that architectural...

Enforcing context-awareness and privacy-by-design in the specification of information systems

Networked physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity, allow for run-time acquisition of user data. This in turn can enable information systems which capture the “current” user state and act accordingly. The use of this data would result in context...

A privacy risk assessment model for open data

While the sharing of information has turned into a typical practice for governments and organizations, numerous datasets are as yet not openly published since they may violate users’ privacy. The hazard on data protection infringement is a factor that regularly hinders the distribution of information and results in a push back from...
