The permute-and-flip mechanism is a recently proposed differentially private selection algorithm that was shown to outperform the exponential mechanism. In this paper, we show that permute-and-flip is equivalent to the well-known report noisy max algorithm with exponential noise.

  1. Plausible Deniability Guarantees for Whistleblowers

    cs.CR 2026-07 accept novelty 7.0 of 10

    A new mechanism gives per-report (0,δ)-differential privacy for whistleblower audit transcripts, with selection error vanishing as report gaps grow faster than √log T.

  2. Differentially Private Multi-objective Selection: Pareto and Aggregation Approaches

    cs.CR 2024-12 conditional novelty 6.0 of 10

    PrivPareto and PrivAgg extend differentially private selection to multiple objectives by composing the sensitivities of individual utility functions into one private score.
