局部私有假设检验:χ 2检验

Local Private Hypothesis Testing: Chi-Square Tests

Marco Gaboardi, Ryan Rogers

摘要:

差分隐私的局部模型正在成为收集和共享敏感信息的实际应用的参考模型,同时满足强隐私保证。在本地模型中,不存在允许每个人的原始数据的可信实体,因为在传统的馆长模型中假设差异隐私。因此,个人数据在共享之前通常会受到干扰。我们探讨了在局部模型中的私人假设检验的设计,其中每个数据条目都被扰动以确保每个参与者的隐私。具体来说,我们分析了本地私人χ 2检验的拟合优度和独立性测试,这已经在传统的,馆长模型的差异隐私研究。

英文摘要:

The local model for differential privacy is emerging as the reference model for practical applications collecting and sharing sensitive information while satisfying strong privacy guarantees. In the local model, there is no trusted entity which is allowed to have each individual's raw data as is assumed in the traditional curator model for differential privacy. So, individuals' data are usually perturbed before sharing them. We explore the design of private hypothesis tests in the local model, where each data entry is perturbed to ensure the privacy of each participant. Specifically, we analyze locally private chi-square tests for goodness of fit and independence testing, which have been studied in the traditional, curator model for differential privacy.
