  • A Privacy Model for Smart Metering
    Communications Workshops ICC 2010 IEEE International Conference on, 2010
    Co-Authors: Jens Matthias Bohli, Christoph Sorge, Osman Ugus
    Abstract:

    Electricity suppliers have started replacing traditional electricity meters with so-called smart meters, which can transmit current power consumption levels to the supplier within short intervals. Though this is advantageous for the electricity suppliers' planning purposes, and also allows the customers a more detailed look at their usage behavior, it means a considerable risk for Privacy. The detailed information can be used to judge whether persons are in the household, when they come home, which electric devices they use (e.g. when they watch TV), and so forth. In this work, we introduce the "smart metering Privacy model" for measuring the Degree of Privacy that a smart metering application can provide. Moreover, we present two design solutions both with and without involvement of trusted third parties. We show that the solution with trusted party can provide "perfect Privacy" under certain conditions.

  • LCN - A Chord-based Recommender System
    32nd IEEE Conference on Local Computer Networks (LCN 2007), 2007
    Co-Authors: Christoph Sorge
    Abstract:

    Traditional recommender systems rely on the use of a central server. This server is a single point of failure; moreover, the need for an expensive central infrastructure may lead to economic dependencies, forming an incentive to manipulate recommendations. Decentralized recommender systems on the basis of peer-to-peer networks can help solving this problem. Most existing approaches, however, are not scalable for large networks, or they do not consider security and Privacy issues. The article at hand presents a peer-to-peer recommender system based on the chord overlay network and item-based collaborative filtering. Scalability is improved by introducing various optimizations. Additionally, we present an approach that reduces the potential for manipulation by system participants while granting a high Degree of Privacy.

  • family accounts a new paradigm for user accounts within the home environment
    Conference on Computer Supported Cooperative Work, 2008
    Co-Authors: Serge Egelman, A Bernheim J Brush, Kori Inkpen
    Abstract:

    In this paper we present Family Accounts, a new user account model for shared home computers. We conducted a study with sixteen families, eight who used individual profiles at home, and eight who shared a single profile. Our results demonstrate that Family Accounts is a good compromise between a single shared profile and individual profiles for each family member. In particular, we observed that because Family Accounts allowed individuals to switch profiles without forcing them to interrupt their tasks, family members tended to switch to their own profiles only when a task required some Degree of Privacy or personalization.

  • THE EPISTEMIC ACCOUNT of Privacy
    Episteme, 2013
    Co-Authors: Martijn Blaauw
    Abstract:

    AbstractPrivacy is valued by many. But what it means to have Privacy remains less than clear. In this paper, I argue that the notion of Privacy should be understood in epistemic terms. What it means to have (some Degree of) Privacy is that other persons do not stand in significant epistemic relations to those truths one wishes to keep private.
