Plausible Deniability Guarantees for Whistleblowers: A Formal Privacy Framework for Anonymous Reporting

arXiv·medium signal

Leo Richter and Matt J. Kusner (arXiv 2607.13928, cs.CR/cs.LG/stat.ML) propose formal plausible-deniability guarantees for whistleblower protection, arguing that existing legal and technical protections fail because retaliation risk persists even when identity is nominally shielded. The work sits at the intersection of differential-privacy-style formalism and real organizational threat models. For builders, this is the rare security paper whose threat model is social rather than cryptographic — relevant to anyone designing internal reporting, audit-log redaction, or anonymous feedback tooling.
