Social networks and other Web 2.0 sites are becoming more and more a part of our culture; however, we are inclined to forget about – or at least ignore – their dangers. Many of us have heard or read stories where somebody was fired because he/she friended his/her boss on Facebook, and the latter found a malignant post about the company they worked for. However, it is good to know that we are in danger even if we do not make so obvious blunders. This article describes the threats we face, and the means of defence against them. One particular defence mechanism, BlogCrypt, is described in details: a simple Firefox plugin that allows encrypting and decrypting web content as easy as it sounds.
We will publish this article on the International PET Portal & Blog the following Friday.
Voluntary disclosure of personal information is becoming more and more widespread with the advent of Web 2.0 services. Publishing such information constitutes new kinds of threats, such as further reinforcing already existing profiling techniques through correlation of perceived user activities to those publicly disclosed, but the most obvious of all is the intrinsic threat that malicious third parties collect and combine information we publish about ourselves. In this paper, we evaluate currently existing solutions that are destined for addressing this issue, then propose a model of our own for providing access control for a user over information she published and analyse our implementation thereof.
