PrivAGM: Secure Construction of Differentially Private Directed Attributed Graph Models on Decentralized Social Graphs
Summary: PrivAGM combines differential privacy and secure multiparty computation to fit directed, attributed graph models when users hold only local views of a decentralized social graph. It preserves edge directionality and attribute–edge correlations, yielding higher-utility synthetic graphs than prior methods. (summarized by gpt-5.6-luna on Jul 24 2026)
