Important Paper: Using Facebook Microtargeted Ads for Privacy Violations
http://j.mp/fywMKR (Stanford [PDF])
Abstract - In this paper we propose a new class of attacks that exploit
advertising systems offering microtargeting capabilities in order to
breach user privacy. We study the advertising system offered by the
world's largest online social network, Facebook, and the risks that
the design of the system poses to the privacy of its users. We
propose, describe and provide experimental evidence of several novel
approaches to exploiting the advertising system in order to obtain
private user information. We communicated our findings to Facebook on
July 13, 2010, and received a very prompt response. On July 20, 2010,
Facebook launched a change to their advertising system that made the
kind of attacks we describe much more difficult but not impossible to
implement.
