AI总结:

本文提出 OptimShare 统一框架,融合差分隐私、模糊逻辑与概率论,通过面向应用的选择性属性扰动提升表格数据共享的实际效用并保障隐私。

摘要:

表格数据共享是数据交换的常用方法。然而,在没有充分隐私保护的情况下共享敏感信息可能损害个人隐私。因此,确保隐私保护型数据共享至关重要。差分隐私(DP)被视为数据隐私领域的黄金标准。尽管如此,当前的 DP 方法往往会生成隐私保护型表格数据集,但由于严重扰动以及忽视表格的效用动态,这些数据集的实际效用通常有限。此外,关于选择性属性发布的研究并不多,尤其是在受控的部分扰动数据共享背景下。这对现实世界中的跨机构数据共享等场景具有重要意义。我们提出 OptimShare:一种以效用为中心的多准则解决方案,旨在选择性地扰动输入数据集,并针对特定现实应用进行优化。OptimShare 结合差分隐私、模糊逻辑和概率论原理,构建了一个用于隐私保护数据共享的集成工具。实证评估证实,OptimShare 成功地在更好的数据效用与强健隐私之间取得平衡,有效服务于各种现实问题场景。

英文摘要:

Tabular data sharing serves as a common method for data exchange. However, sharing sensitive information without adequate privacy protection can compromise individual privacy. Thus, ensuring privacy-preserving data sharing is crucial. Differential privacy (DP) is regarded as the gold standard in data privacy. Despite this, current DP methods tend to generate privacy-preserving tabular datasets that often suffer from limited practical utility due to heavy perturbation and disregard for the tables' utility dynamics. Besides, there has not been much research on selective attribute release, particularly in the context of controlled partially perturbed data sharing. This has significant implications for scenarios such as cross-agency data sharing in real-world situations. We introduce OptimShare: a utility-focused, multi-criteria solution designed to perturb input datasets selectively optimized for specific real-world applications. OptimShare combines the principles of differential privacy, fuzzy logic, and probability theory to establish an integrated tool for privacy-preserving data sharing. Empirical assessments confirm that OptimShare successfully strikes a balance between better data utility and robust privacy, effectively serving various real-world problem scenarios.
