演讲简介

Machine learning has witnessed tremendous progress during the past decade. While keeping on improving our life quality, machine learning models may raise severe concerns towards people’s privacy. In this talk, I will cover our recent work on assessing privacy risks stemming from machine learning models. First, I will talk about membership inference attacks against machine learning models. We show how to relax adversary’s assumptions to achieve a model and data independent membership inference attack. Then, I will discuss our work on attacking online learning systems. We propose four effective attacks in this surface ranging from predicting attributes of the dataset used to update a machine learning model to reconstructing the updating dataset itself. In the end, I will discuss our lab's ongoing works in machine learning security and privacy.
