Abstract: The increasing adoption of differential privacy (DP) leads to public-facing DP deployments by both government agencies and companies. However, real-world DP deployments often do not fully disclose their privacy guarantees, which vary greatly between deployments. Failure to disclose certain DP parameters can lead to misunderstandings about the strength of the privacy guarantee, undermining the trust in DP. In this work, we seek to inform future standards for communicating the privacy guarantees of DP deployments. Based on semi-structured interviews with 12 DP experts, we identify important DP parameters necessary to comprehensively communicate DP guarantees, and describe why and how they should be disclosed. Based on expert recommendations, we design an initial privacy label for DP to comprehensively communicate privacy guarantees in a standardized format.

We present DPolicy, a system designed to manage cumulative privacy risks across multiple data releases using Differential Privacy (DP)<n>Unlike traditional approaches that treat each release in isolation or rely on a single (global) DP guarantee, our system employs a flexible framework that considers multiple DP guarantees simultaneously.<n>DPolicy introduces a high-level policy language to formalize privacy guarantees, making traditionally implicit assumptions on scopes and contexts explicit.

DPMAC: Differentially Private Communication for Cooperative Multi-Agent Reinforcement Learning [21.961558461211165]
Communication lays the foundation for cooperation in human society and in multi-agent reinforcement learning (MARL) We propose the textitdifferentially private multi-agent communication (DPMAC) algorithm, which protects the sensitive information of individual agents by equipping each agent with a local message sender with rigorous $(epsilon, delta)$-differential privacy guarantee. We prove the existence of a Nash equilibrium in cooperative MARL with privacy-preserving communication, which suggests that this problem is game-theoretically learnable.

A Randomized Approach for Tight Privacy Accounting [63.67296945525791]
We propose a new differential privacy paradigm called estimate-verify-release (EVR) EVR paradigm first estimates the privacy parameter of a mechanism, then verifies whether it meets this guarantee, and finally releases the query output. Our empirical evaluation shows the newly proposed EVR paradigm improves the utility-privacy tradeoff for privacy-preserving machine learning.
