Preserving user trust in recommender system depends on the perception of the system as objective, unbiased, and accurate. However, publicly accessible user-adaptive systems such as collaborative recommender systems present a security problem. Attackers, closely resembling ordinary users, might introduce biased profiles to force the system to adapt in a manner advantageous to them. The authors discuss some of the major issues in building secure recommender systems, including some of the most effective attacks and their impact on various recommendation algorithms. Approaches for responding to these attacks range from algorithmic approaches to designing more robust recommenders, to effective methods for detecting and eliminating suspect profiles.
