Abstract
A systematic method of introducing obfuscating “organic” noise to a user's content engagement history leverages a recommender system by creating a public history on a client device which is a superset of the user's true engagement history. The method builds up the superset history over time through a client's interaction with the recommender system by simulating organic growth in a user's actual engagement history. The organic superset prevents an adversary with access to the underlying recommendation model from readily distinguishing between signal and noise in a user's query and obfuscates the user's engagement history with the recommender system.
