Title: Improving Transparency and Data Access Rights for Targeted Advertising

Advertising networks collect extensive data about consumers, making inferences about their interests, demographics, and more to enable highly targeted advertising. This talk will discuss a series of recent projects aimed to improve consumers' understanding of these practices and their consequences. I will first discuss Tracking Transparency, a browser extension prototype we have developed to give consumers a more comprehensive view of the extent and implications of data collection for advertising purposes. I will next present a deception-based user study we conducted to understand consumers' reactions to data being recontextualized to provide highly personalized advertising. While participants found this practice creepy, it surprisingly did not impact their subsequent information-disclosure decisions. The remainder of the talk will focus on subject data access rights, or consumers' ability to download a copy of the personal data a company holds about them. I will highlight how having 231 consumers download their own Twitter data and share it with us provided insight into the current ecosystem of targeted ads and existing transparency mechanisms. I will conclude with our ongoing work aiming to make data-access rights more useful and informative for consumers.
