不同私有数据合成方法的比较研究

Comparative Study of Differentially Private Data Synthesis Methods

Claire McKay Bowen, Fang Liu

摘要:

在研究人员之间共享数据或发布数据供公众使用时,存在暴露数据集中个人敏感信息的风险。数据合成(DS)是一种统计披露限制技术,用于发布具有伪个体记录的合成数据集。传统的DS技术通常依赖于对数据入侵者的行为和背景知识的强假设来评估泄露风险。差分隐私(DP)制定了一个强大的和鲁棒的隐私保证在数据发布的理论方法,而不必建模入侵者的行为。已经做出努力,旨在将DP概念纳入DS过程。在本文中,我们研究目前的差异私有数据合成(DIPS)技术释放个人层面的替代数据的原始数据,比较技术的概念,并通过广泛的模拟研究,通过每个DIPS技术的合成数据的统计效用和推理性能进行评估。我们的工作揭示了各种DIPS方法的实际可行性和实用性,并提出了未来的研究方向。

英文摘要:

When sharing data among researchers or releasing data for public use, there is a risk of exposing sensitive information of individuals in the data set. Data synthesis (DS) is a statistical disclosure limitation technique for releasing synthetic data sets with pseudo individual records. Traditional DS techniques often rely on strong assumptions of a data intruder's behaviors and background knowledge to assess disclosure risk. Differential privacy (DP) formulates a theoretical approach for a strong and robust privacy guarantee in data release without having to model intruders' behaviors. Efforts have been made aiming to incorporate the DP concept in the DS process. In this paper, we examine current DIfferentially Private Data Synthesis (DIPS) techniques for releasing individual-level surrogate data for the original data, compare the techniques conceptually, and evaluate the statistical utility and inferential properties of the synthetic data via each DIPS technique through extensive simulation studies. Our work sheds light on the practical feasibility and utility of the various DIPS approaches, and suggests future research directions for DIPS.
