Researchers have developed a new defense mechanism called TIER (Trajectory-Invariant Explanation Regularization) to protect AI models against membership inference attacks. These attacks exploit how an AI's confidence changes when its explanations are perturbed, rather than just the explanations themselves. TIER works by regularizing the model during training to ensure that explanation profiles remain consistent between members and non-members, thereby reducing the effectiveness of these privacy attacks while preserving model utility and explanation fidelity.
