Talk Overview
Steal it if you can

Machine learning (ML) is becoming an integral part of many products. With a growing number of applications incorporating ML models, it is important to ask what are the security and privacy implications. In this talk we will first introduce security and privacy attacks on ML at a practical level. Then we will focus on model stealing attacks. These attacks view a deployed model as a black box and attempt to replicate it by creating a “copy-cat” model that can be subsequently used as a “white-box” model. We will discuss why these attacks are interesting, how they work and what are the most important considerations for their success, as well as some defenses against them. We will also go through some real world examples of stealing models that are used in security applications and provide material and tools that can be used as a starting point for people interested in delving into the area of machine learning security.
