信度函数的局部差分隐私

Local Differential Privacy for Belief Functions

Qiyu Li, Chunlai Zhou, Biao Qin, Zhiqiang Xu

摘要:

在本文中,我们提出了两个新的局部差分隐私的信念函数的定义。一个是基于Shafer的语义的随机编码的消息和其他不精确的概率的角度来看。我们表明,这些基本属性的组合物和后处理也适用于我们的新定义。此外,我们为这些定义提供了一个假设检验框架,并研究了离散分布估计中“不知道”在隐私和效用之间权衡的影响。

英文摘要:

In this paper, we propose two new definitions of local differential privacy for belief functions. One is based on Shafer's semantics of randomly coded messages and the other from the perspective of imprecise probabilities. We show that such basic properties as composition and post-processing also hold for our new definitions. Moreover, we provide a hypothesis testing framework for these definitions and study the effect of "don't know" in the trade-off between privacy and utility in discrete distribution estimation.
