噪声信道下假设检验的隐私-效用权衡

Privacy-Utility Tradeoff for Hypothesis Testing Over A Noisy Channel

Lin Zhou, Daming Cao

摘要:

我们研究了在噪声信道中具有隐私约束的假设检验问题,并推导了在Neyman-Pearson准则下的最优检验性能。感兴趣的基本限制是隐私效用权衡(PUT)之间的指数的类型II错误概率和泄漏的信息源受到恒定的约束类型I错误概率。我们提供了一个精确的表征的渐近放置任何非零I型错误概率。我们的结果意味着容忍较大的I类错误概率不能提高PUT。这样的结果被称为强逆定理或强不可能定理。为了证明强逆定理,我们应用了最近在(Tyagi和Watanabe,2020)中提出的技术,并进一步证明了它的通用性。几个问题的强逆定理,如假设检验对噪声信道的独立性(Sreekumar和Gündüz,2020)和假设检验与通信和隐私约束(Gilani \emph{et al.},2020),建立或恢复为我们的结果的特殊情况。

英文摘要:

We study a hypothesis testing problem with a privacy constraint over a noisy channel and derive the performance of optimal tests under the Neyman-Pearson criterion. The fundamental limit of interest is the privacy-utility tradeoff (PUT) between the exponent of the type-II error probability and the leakage of the information source subject to a constant constraint on the type-I error probability. We provide an exact characterization of the asymptotic PUT for any non-vanishing type-I error probability. Our result implies that tolerating a larger type-I error probability cannot improve the PUT. Such a result is known as a strong converse or strong impossibility theorem. To prove the strong converse theorem, we apply the recently proposed technique in (Tyagi and Watanabe, 2020) and further demonstrate its generality. The strong converse theorems for several problems, such as hypothesis testing against independence over a noisy channel (Sreekumar and Gündüz, 2020) and hypothesis testing with communication and privacy constraints (Gilani \emph{et al.}, 2020), are established or recovered as special cases of our result.
