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.

ECCOLA : a method for implementing ethically aligned AI systems
2021
Artificial Intelligence (AI) systems are becoming increasingly widespread and exert a growing influence on society at large. The growing impact of these systems has also highlighted potential issues that may arise from their utilization, such as data privacy issues, resulting in calls for ethical AI systems. Yet, how to develop ethical AI systems remains an important question in the area. How should the principles and values be converted into requirements for these systems, and what should developers and the organizations developing these systems do? To further bridge this gap in the area, in this paper, we present a method for implementing AI ethics: ECCOLA. Following a cyclical action res…
An Efficient and Secure Multidimensional Data Aggregation for Fog-Computing-Based Smart Grid
2021
International audience; The secure multidimensional data aggregation (MDA) has been widely investigated in smart grid for smart cities. However, previous proposals use heavy computation operations either to encrypt or to decrypt the multidimensional data. Moreover, previous fault-tolerant mechanisms lead to an important computation cost, and also a high communication cost when considering a separate identification phase. In this article, we propose an efficient and secure MDA scheme, named ESMA. Unlike existing schemes, the multidimensional data in ESMA are structured and encrypted into a single Paillier ciphertext and thereafter, the data are efficiently decrypted. For privacy preserving, …
