PrivPetal: Relational Data Synthesis via Permutation Relations
Summary: PrivPetal uses permutation relations to synthesize a flattened view, then decomposes to base tables, avoiding DP on join keys. A refined Markov random field with fine-grained privacy analysis delivers high-utility synthetic data, beating PrivLava on aggregate queries across real data and TPC-H.
