  Abstract

Online advertisements are delivered through real-time bidding(RTB) and behavioral targeting of users. The user profile sent in the ad request contains data that infringes on user privacy and is propagated and stored throughout the RTB network by the actors seeking to increase their performance and profitability. In this paper, we propose to leverage Functional Encryption(FE) to preserve user privacy. Our implementation showed that it can be integrated to the current RTB ecosystem and provide real-time(< 20ms) privacy-preserving advertising with minimal changes.
