With increasing opportunities for cheaper outsourcing of data, more and more organizations are seriously considering this option to reduce storage and processing costs. However, it has also given rise to the possibilities of security and privacy violations of data in outsourced environments. In this paper, we look at the privacy aspect, often referred to as data confidentiality. Our solution employs...
We do a survey of some of the most important principles of anonymization present in the literature. We identify different kinds of attacks that can be thrown against an anonymized dataset and give formulas for the maximum probability of success for each. For each principle, we identify whether it is monotonous, what attacks it is suited to counter, if any, and what principles imply other principles...
This paper presents a method for extractive multi-document summarization that explores a two-phase clustering approach that, combined with a sentence simplification procedure, aims to generate more useful summaries. First, sentences are clustered by similarity, and one sentence per cluster is selected, to reduce redundancy. Then, in order to group them according to topics, those sentences are clustered...
Despite predicted benefits of data integration in the sciences, many factors continue to limit data sharing. In this paper we argue that data practices of individual researchers represent a key bottleneck. Through an interview study across multiple fields, we show that data practices vary as a function of norms learned from senior mentors, where data sharing is more likely when supported and modeled...
In today's complex and changing world, government and business organizations need to reuse and share not only data and computing facilities, but also organizational policies, constraints, regulations and processes in order to achieve inter-organizational collaboration and coordination. Organizational resources as well as organizations' partnership can change at any time in a dynamic environment. Thus,...
In a provenance-aware environment, as data objects are created and used, the transaction information is captured as provenance data. Provenance-based access control utilizes the captured provenance information to control access to the underlying data. In a group-centric collaboration environment, data objects are shared and modified by multiple organizations/systems while the relevant provenance data...
