Researchers have developed PPGNN, a new framework designed for personalized differential privacy in decentralized graph learning. This approach addresses the limitations of existing methods that apply uniform privacy settings, which can distort data and reduce utility. PPGNN allows for user-specific privacy budgets during local perturbation, aiming to better balance privacy protection with data utility. Experiments on six real-world datasets indicate that PPGNN effectively manages personalized privacy and data utility in decentralized graph learning scenarios. AI
