The authors propose PriView, an interactive privacy preserving personalized video consumption system that protects a user's privacy while delivering relevant content recommendations to the user. PriView provides the user with three functionalities: transparency on privacy risk, control of privacy risk, and personalized content recommendations. PriView bridges privacy theory and practice: it successfully implements an information theoretic framework to design a utility-aware privacy-preserving mapping that perturbs a user's video ratings to prevent inference of user private attributes, e.g. political views, age, gender, while maintaining the utility of the released perturbed ratings for recommendation.
