隐私保护数据合成的合理否认

Plausible deniability for privacy-preserving data synthesis

Song Mei, Zhiqiang Ye

摘要:

在隐私保护领域,发布完整数据(尤其是高维数据集)是最具挑战性的问题之一。普通加密技术无法应对攻击者采取差分攻击获取敏感信息,而现有的差分隐私保护算法模型高维计算耗时长,需要加入噪声降低数据精度,不适合高维大数据集。针对这种情况,本文围绕“似是而非的否认”概念,设计了一套完整的数据合成方案来保护数据隐私。本文首先从理论上对“似然数据”与“似然数据”的区别进行了论证。在方案设计过程中,将方案设计分解为构造数据合成模块和隐私检测模块,分别设计了算法模型,实现了隐私保护功能。在评估方案可行性时,选取美国2013年社区人口普查结果作为高维数据集,使用基于Python的仿真程序对数据合成方案的效率和可靠性进行了测试和分析。本部分集中于评估该计划的隐私保护成效。

英文摘要:

In the field of privacy protection, publishing complete data (especially high-dimensional data sets) is one of the most challenging problems. The common encryption technology can not deal with the attacker to take differential attack to obtain sensitive information, while the existing differential privacy protection algorithm model takes a long time for high-dimensional calculation and needs to add noise to reduce data accuracy, which is not suitable for high-dimensional large data sets. In view of this situation, this paper designs a complete data synthesis scheme to protect data privacy around the concept of "plausible denial". Firstly, the paper provides the theoretical support for the difference between "plausible data" and "plausible data". In the process of scheme designing, this paper decomposes the scheme design into construction data synthesis module and privacy test module, then designs algorithm models for them respectively and realizes the function of privacy protection. When evaluating the feasibility of the scheme, the paper selects the Results of the 2013 community census in the United States as the high-dimensional data set, uses the simulation program that is based on Python to test and analyzes the efficiency and reliability of the data synthesis scheme. This portion focuses on the evaluation of the privacy protection effectiveness of the scheme.
