- We investigate the end users’ behaviours and attitudes with regards to the control they place in the personal information that they disclose to cloud storage services. Three controlled experiments were carried out to study the influence in users’ decisions to retain or surrender control over their personal information depending on different factors. The results of these experiments reveal, among other things, the users’ willingness to surrender control over personal information that is perceived as non-sensitive in exchange for valuable rewards, and that users would value the possibility of knowing and controlling the parties who are granted access to their data in the cloud. Based on the results from the experiments we provide implications for the design of end-user tools that can promote transparency and accountability in cloud computing environments.

Information Classification Issues
- 2014

Konferensbidrag (refereegranskat)abstract
- This paper presents an extensive systematic literature review with the aim of identifying and classifying issues in the information classification process. The classification selected uses human and organizational factors for grouping the identified issues. The results reveal that policy-related issues are most commonly described, but not necessarily the most crucial ones. Furthermore, gaps in the research field are identified in order to outline paths for further research.

Event Invitations in Privacy-Preserving DOSNs : Formalization and Protocol Design

- Online Social Networks (OSNs) have an infamous history of privacy and security issues. One approach to avoid the collection of massive amounts of sensitive user data at a central point is a decentralized architecture.An event invitation feature - allowing a user to create an event and invite other users who then can confirm their attendance - is part of the standard functionality of OSNs. Implementing this feature in a Privacy-Preserving Decentralized Online Social Network (DOSN) is non-trivial because there is no fully trusted broker to guarantee fairness to all parties involved.In this work we look into decentralized protocols for implementing event invitation features. We formalize possible security and privacy properties of such a feature and propose a secure implementation allowing different types of information related to the event (e.g., how many people are invited/attending, who is invited/attending) to be shared with different groups of users (e.g., only invited/attending users).The results can be applied in the context of Privacy-Preserving DOSNs, but might also be useful in other domains such as Collaborative-Working Environment (CWE) and their corresponding collaborative-specific tools (i.e., groupware).
