论文摘要
社会选择功能有助于汇总个人偏好,而不同的私人机制则提供了正式的隐私保证,可以发布在敏感数据上运行的查询答案。但是,保留差异隐私需要向系统引入噪声,因此可能导致不希望的副产品。释放社会选择功能的产出的差异隐私水平的提高是否会增加或降低影响力和福利水平,以及以什么速度?在本文中,我们主要在全民公决环境中以更精确的术语与两个候选人一起解决这个问题。我们表明,福利与隐私之间存在成反比的关系,也有影响和隐私。
Social choice functions help aggregate individual preferences while differentially private mechanisms provide formal privacy guarantees to release answers of queries operating on sensitive data. However, preserving differential privacy requires introducing noise to the system, and therefore may lead to undesired byproducts. Does an increase in the level of differential privacy for releasing the outputs of social choice functions increase or decrease the level of influence and welfare, and at what rate? In this paper, we mainly address this question in more precise terms in a referendum setting with two candidates when the celebrated randomized response mechanism is used. We show that there is an inversely-proportional relation between welfare and privacy, and also influence and privacy.
