Title: “我们需要一个标准”：面向差分隐私的专家指导隐私标签

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. Show Chinese abstract

Abstract: 差分隐私（DP）的日益采用，使得政府机构和公司都开始部署面向公众的DP系统。然而，现实世界中的DP部署通常并未充分披露其隐私保证，这些保证在不同部署之间差异很大。未能披露某些DP参数可能导致对隐私保证强度的误解，从而削弱对DP的信任。在本工作中，我们旨在为未来沟通DP部署的隐私保证的标准提供信息。基于对12位DP专家的半结构化访谈，我们确定了全面传达DP保证所需的重要DP参数，并描述了它们应被披露的原因和方式。根据专家的建议，我们设计了一个初始的DP隐私标签，以标准化格式全面传达隐私保证。
