DPrivBench: Benchmarking LLMs' Reasoning for Differential Privacy

Eli Chien, Erchi Wang, Kamalika Chaudhuri, Om Thakkar, Pengrun Huang, Ruihan Wu, Yu-Xiang Wang

DPrivBench shows that top LLMs handle basic differential privacy mechanisms but fail on advanced algorithms, exposing gaps in automated DP reasoning.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments show that while the strongest models handle textbook mechanisms well, all models struggle with advanced algorithms, revealing substantial gaps in current DP reasoning capabilities.

C2weakest assumption

The benchmark instances are free of shortcut reasoning patterns and correctly labeled as to whether each function satisfies the stated DP guarantee under the given assumptions.

C3one line summary

DPrivBench shows that top LLMs handle basic differential privacy mechanisms but fail on advanced algorithms, exposing gaps in automated DP reasoning.
