To Share or Not to Share: Supporting the User Decision in Mobile Social Software Applications

2007

User's privacy concerns represent one of the most serious obstacles to the wide adoption of mobile social software applications. In this paper, we introduce a conceptual model which tackles the problem from the perspective of trade-off between privacy and trust, where the user takes the decision with minimal privacy loss. To support the user decision, we introduce the Mobile Access Control List (Macl), a privacy management mechanism which takes into account the user attitude towards mobile sharing, his communication history and social network relationships.

DICOM E-mail: Germany's minimum standard for teleradiology

2005

Abstract Due to the lack of a standard for teleradiology, the IT Working Group (Arbeitsgemeinschaft fur Informationstechnik, @GIT) of the German Radiological Society (Deutsche Rontgengesellschaft, DRG) has set up an initiative for standardizing telemedicine. E-mail has been selected as the ideal basis for ad hoc connections in teleradiology since it is both easy to implement and use. The DICOM standard offers the option of appending DICOM data types as MIME attachments to any e-mail, thus enabling the transmission of the original DICOM data. Nevertheless, there are additional requirements (e.g., data privacy) that must be obeyed and implemented. The first recommendation was introduced at th…

Internet of things and privacy preserving technologies

2009

In this paper we consider different approaches to technological protection of users' privacy in the world of internet of things. Particularly, we consider what kind of problems and which level of protection can be achieved by applying approaches using secure multi-party computations.

Privacy in Social Network Sites

2011

Are we running out of privacy? Nowadays, for example, we are concerned about whether the maintenance of a private sphere in online environments has become a luxury commodity (Papacharissi 2009). Questions of this kind are justified as online communication plays an increasingly important role in people’s everyday life (cf., e.g., Lundby 2009). While it seems exaggerated to stigmatize today’s youth as “communication junkies” (Patalong 2010), online conversations are increasingly becoming a functional equivalent to face to face communication (Beer 2008). However, some significant differences between online and “offline” communication remain. Face to face communication may remain largely intima…

Access Security and Personal Privacy in Public Cellular Communication Systems: The Past, the Present and Beyond 2020

2010

In order to predict the future one needs to understand the past and then interpolate as best as possible. We expect this to work reasonably well for a “2020 Scenario”, but we do not expect this approach to be valid for a “Beyond 2020” scenario.

Trust-enhanced intelligent security model

2012

In this paper we propose a trust-enhancement of access control to protect both integrity and confidentiality based on trustworthiness of users performing operations and documents' content analysis. We propose to utilize trustworthiness opinions from subjective logic and express levels of integrity as levels of trustworthiness. We assign confidentiality levels based on contents of documents and use opinions to express trustworthiness of such assignments.

Rings for privacy: An architecture for privacy-preserving user profiling

Publish By Example

2008

We propose an approach for producing database publishing programs by example. The main idea is to interactively build an example document, representative of the program output. The system infers from this document, without ambiguity, the publishing program. The end-user does not need to know a programming language, a query language or the database schema.

Towards semantic-based RSS merging

2009

Merging information can be of key importance in several XML-based applications. For instance, merging the RSS news from different sources and providers can be beneficial for end-users (journalists, economists, etc.) in various scenarios. In this work, we address this issue and mainly explore the relatedness relationships between RSS entities/ elements. To validate our approach, we also provide a set of experimental tests showing satisfactory results. © 2009 Springer-Verlag Berlin Heidelberg
