Study Notes
- Lecture by Dr. Yisroel Mirsky on Adversarial Machine Learning covering Confidentiality Attacks and Causative Attacks
- Example of a confidentiality attack: Using Bob's CT scans to train a cancer detection model, leading users to infer that Bob has cancer
- Threat model for privacy attacks in Machine Learning includes wanting information from MLaaS providers like Amazon, Google, Microsoft, etc.
- Inferring the model's parameters attack goal involves stealing the parameters (θ) from the model (fθ) through model extraction methods like Exact Copy or Approximation
- Model extraction can be achieved by learning the decision boundary (hyperplane) using methods like the Copycat Approach, where the attacker needs access to the model (f), data (x), and API to steal the model
