Tracking and Personalization

Abstract

AbstractThis chapter studies the relationship between two important, often conflicting paradigms of online services: personalization and tracking. The chapter initially focuses on the categories and levels of online personalization, briefly overviewing algorithmic methods applied to achieve these. Then, the chapter turns to online tracking specific to mobile and web technologies, as well as the more advanced behavioral tracking. Following this, the chapter ties the streams of personalization and tracking together and discusses various aspects of their relationships, including the currently deployed tracking methods for personalization. Privacy implications of personalization via online tracking, highlighted by organizations and researchers, are also illustrated. Lastly, this chapter discusses the ways to balance personalization benefits and privacy concerns. This includes the state-of-the-art practices, current challenges, and practical recommendations for system developers willing to strike this balance.
