Trust and Privacy in Knowledge Graphs [article]

Daniel Schwabe, Carlos Laufer
2019 arXiv   pre-print
This paper presents the KG Usage framework, which allows the introduction of KG features to support Trust, Privacy and Transparency concerns regarding the use of its contents by applications.  ...  A real-world example is presented and used to illustrate how the framework can be used.  ...  In order to be effective, we claim that the use of Knowledge Graphs must support these concerns -trust, privacy and transparency. In this paper we propose a framework that enables this support.  ...

Preserving the Privacy of Sensitive Relationships in Graph Data [chapter]

Elena Zheleva, Lise Getoor
Privacy, Security, and Trust in KDD  
In this paper, we focus on the problem of preserving the privacy of sensitive relationships in graph data.  ...  We propose five different privacy preservation strategies, which vary in terms of the amount of data removed (and hence their utility) and the amount of privacy preserved.  ...  Link Re-identification Attacks The extent of a privacy breach is often determined by data domain knowledge of the adversary. The domain knowledge can influence accurate inference in subtle ways.  ...

A Privacy-Preserving Social P2P Infrastructure for People-Centric Sensing

Michael Dürr, Kevin Wiesner, Marc Herbstritt
2011 Networked Systems  
In this paper, we propose a protocol extension to our OSN design Vegas which enables secure, privacy-preserving, and trustful P2P communication between PCS participants.  ...  By securing knowledge about social links with standard public key cryptography, we achieve a degree of anonymity at a trust level which is almost good as that provided by a centralized trusted third party  ...  To the best of our knowledge, our approach is the first that uses an OSN to ensure privacy and trust in PCS networks.  ...

Privacy-preserving function computation by exploitation of friendships in social networks

Farid M. Naini, Jayakrishnan Unnikrishnan, Patrick Thiran, Martin Vetterli
2014 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
We demonstrate that such trust relationships can be exploited to significantly improve the tradeoff between the privacy of users' data and the accuracy of the computation.  ...  We study the problem of privacy-preserving computation of functions of data that belong to users in a social network under the assumption that users are willing to share their private data with trusted  ...  Other privacy measures used in the literature include confidence intervals [3] , mutual information [13, 14] , priori and posteriori knowledge [15, 16] , game theory [17] , and cryptographic notions  ...
