Selling off User Privacy at Auction presented at NDSS 2014

by Claude Castelluccia, Lukasz Olejnik, Minh-dung Tran,

Summary : This paper studies how personal data is exchanged by advertising companies via Real Time Bidding (RTB) and Cookie Matching. We show that a large proportion of users’ web histories leaks to 3rd-party companies through RTB, and that users' browsing history elements are routinely being sold off for less than $0.0005.
