VDDP: Verifiable Distributed Differential Privacy under the Client-Server-Verifier Setup
VDDP introduces a client-server-verifier architecture that lets participants cryptographically verify servers are honestly applying differential privacy, closing a trust gap in distributed settings.

arXiv:2504.21752v4 Announce Type: replace Abstract: Although differential privacy (DP) is widely regarded as the de facto standard for data privacy, its implementation remains vulnerable to unfaithful execution by servers, particularly in distributed settings. In such cases, servers may sample noise from incorrect distributions or generate correlated noise while appearing to follow established protocols. This work addresses these malicious behaviours in a distributed client-server-verifier setu
Editorial Analysis
Enterprises deploying distributed analytics under GDPR face the risk that servers silently weaken privacy guarantees; verifiable DP offers a cryptographic countermeasure.
