5月15日下午4:00-5:30,悉尼科技大学(University of Technology Sydney, Australia)Wanlei Zhou教授应邀在广州大学行政西楼前座428会议室给计算机学院师生做了题为“Answering differentially private queries for continual datasets release”的学术报告,会议由计算机学院副院长王国军教授主持。
报告中Wanlei Zhou教授首先介绍了公开数据集中隐私数据处理的研究工作,提到了一种用比特流处理固定数据集隐私数据的方法,该方法先用0/1数据流表示数据集中的数据隐私,把噪音数据插入到相应的时间戳数据中,达到隐私保护的目的。Wanlei Zhou教授提出了该方法不适用于有时空关联性的数据集,并使用出租车公司发布的数据集中涉及的用户位置隐私作为实例说明日常生活中数据集之间存在的时空关联性。为此,Zhou教授提出了一种面向聚合数据的隐私保护CCR(Couple Continual Release)机制。引入差分隐私方法添加噪声保护用户位置隐私。最后,Wanlei Zhou教授与王国军教授及参会的师生就数据比特流的应用场景、差分隐私应对的攻击类型等问题展开了讨论,。此次报告让在场的师生获益良多。
