Secure, Privacy-Preserving, and Context-Restricted Information Sharing for Location-based Social Networks

Abstract:
Today, Online Social Network (OSN) providers like Facebook or Google provide their users with web-based Location-based Services (LBSs) like Facebook Places or Google Latitude. To facilitate proactive LBS, most OSN providers also offer Location-based Social Network Services (LB-SNSs) for mobile platforms like the iPhone, Android, or Symbian. A multitude of LB-SNSs focus on proximity detection of nearby friends. However, at present almost non of these implementations guarantees a sufficient degree of information security and privacy as well as location integrity for its users. In this paper we address these shortcomings in two ways. We define a set of requirements we deem indispensable to enable LB-SNSs that facilitate secure and privacy-preserving information sharing and guarantee for location integrity at the same time. We then present an extension to our decentralized OSN architecture Vegas which incorporates these requirements and therefore supports the secure, privacy-preserving, and location-restricted provision of LB-SNSs.
