Abstract:

Machine learning (ML) and cloud computing have collaboratively shifted the paradigm of all walks of life. The core of this new paradigm is the large-scale machine learning models that power Machine Learning as a Service (MLaaS). Obviously, they are valuable assets to the model owners who spend great resources in building them. However, by exploiting the inference results of well orchestrated queries from an ML model, an adversary could learn the internals or even the full extents of it, also known as model extraction (ME) attacks. Alternatively, these models may also leak training data information, known as membership inference or model inversion, or suffer from model poisons. In this talk, I will first give an introduction to these attacks. Then I will present several recent works on enhancing the performance of these attacks and defense schemes. Finally, I will show some open challenges in this field.
