Topic Model based Privacy Protection in Personalized Web Search

In modern search engines, personalization introduces potential risk of revealing user privacy by identifying their underlying interests from their logged search behaviors. As a solution of this problem we proposed a client-centered approach to hide user intents. We prevent search engine from building user profile by injecting cover queries with the original user issued query in a controlled way. Each user’s query is submitted with a set of cover queries which carry similar amount of information to generalize user profile while still having some personalization. We used LDA-C topic modeling to generate topic proportion of the original query. By using this topic proportion we used language model to generate cover queries of similar entropy but on unrelated topics. The performance of our proposed model is evaluated in terms of user profile variation from the initial user profile in privacy settings and non-privacy settings.
