在本文中,我们专注于回答查询,在一个不同的私人方式,在图流。我们采用隐私的滑动窗口模型,我们希望对最后的W更新进行分析,并确保整个流的隐私得到保护。我们表明,在这个模型中,确保不公开隐私的代价是最小的。此外,由于在后处理下保留了不同的隐私,因此我们的结果可以用作许多任务中的子例程,最值得注意的是解决切割函数和谱聚类。
In this paper, we focus on answering queries, in a di ↵ erentially private manner, on graph streams. We adopt the sliding window model of privacy, where we wish to perform analysis on the last W updates and ensure that privacy is preserved for the entire stream. We show that in this model, the price of ensuring di ↵ erential privacy is minimal. Furthermore, since di ↵ erential privacy is preserved under post-processing, our results can be used as a subroutine in many tasks, most notably solving cut functions and spectral clustering.
