Private Graph Extraction via Feature Explanation
Rishi Raj SahooPublished: at 02:00 PMThis study explores privacy leakage in GNNs through graph reconstruction attacks using feature explanations. It compares explanation methods—gradient-based, perturbation-based, and surrogate model-based—showing that explanations aid graph reconstruction, with a trade-off between privacy and utility. A defense using randomized response is proposed to reduce attack success.
