Title: Attacks, Defenses, and Impacts of Machine Learning in Adversarial Settings

Abstract:

Advances in machine learning have enabled to new applications and services to process inputs in previously unthinkably complex environments. Autonomous cars, data analytics, adaptive communication systems and self-aware software systems are now revolutionizing markets and blurring the lines between computer systems and real intelligence. In this talk, I consider evolving use of machine learning in security-sensitive contexts and explore why many systems are vulnerable to nonobvious and potentially dangerous manipulation. Here, we examine sensitivity in any application whose misuse might lead to harm—for instance, forcing adaptive network in an unstable state, crashing an autonomous vehicle or bypassing an adult content filter. I explore the use of machine learning in this area particularly in light of discoveries in the creation of adversarial samples and defenses against them, and posit on future attacks on machine learning. The talk is concluded with a discussion of the unavoidable vulnerabilities of systems built on probabilistic machine learning, and outline areas for offensive and defensive research in the future.

Title: Differential Privacy: Potential and Limitations

Abstract:

Differential privacy (DP) has been increasingly accepted as the de facto standard for data privacy in the research community.  Recently, techniques for satisfying DP in the local setting have been deployed by Google and Apple.  In this setting, each user perturbs her date before sending it out.  This enables the gathering of statistics while preserving privacy of every user, without relying on trust in a single data curator.  In the talk, we present our optimized protocols for satisfying DP in the local setting, and discuss the power and limitations of such techniques.  Furthermore, we will explore whether satisfying DP is indeed sufficient for protecting privacy, in both the standard setting and the local setting.
