Decentralized Systems for Privacy Preservation
This report documents the program and the outcomes of Dagstuhl Seminar 13062 “Decentralized Systems for Privacy Preservation”. In recent years, a number of concerns have risen about the existence of large, organizationally centralized online services (cloud services, online social networks, repositories, etc). The concerns include risks to users’ data from organizational failures and threats to...
متن کاملEnforcing Privacy in Decentralized Mobile Social Networks
This position paper first summarizes work done by the first author on location privacy and differential privacy. These techniques will help to solve privacy problems in decentralized mobile social networks, which is the main theme of his PhD research. The paper then briefly reviews the state-of-the-art in privacy-preservation of social graphs and clarifies the lack of attention to graph sharing...
متن کاملSupporting Privacy in Decentralized Additive Reputation Systems
Previous studies have been suggestive of the fact that reputation ratings may be provided in a strategic manner for reasons of reciprocation and retaliation, and therefore may not properly reflect the trustworthiness of rated parties. It thus appears that supporting privacy of feedback providers could improve the quality of their ratings. We argue that supporting perfect privacy in decentralize...
متن کاملPrivacy Preservation in a Decentralized Calendar System
Privacy perservation, in terms of sensitive data access and management, is an important feature of decentralized calendar systems. Indeed, when users delegate their sensitive data such as timetables to an autonomous agent, this one executes many automatic data processing without their intervention: users lost a part of their data control. To tackle this problem, we propose in this article to ex...

Reputation systems are a key technology for making users accountable for their behavior in online communities. A reputation system computes the reputation of a user based on the feedback provided by the community. If the user draws negative feedback, it loses good reputation and may eventually be excluded from the network. It has been observed that users in a reputation system often hesitate in...
