Privacy is to date one of the major impediment for Machine Learning (ML), when applied to sensitive dataset. One popular example is the case of ML applied to the medical domain, but this generally extends to any data scenario in which sensitive data have or simply cannot be used. Moreover, data anonymisation methods are also not enough to guarantee that privacy will be completely preserved. In fact, it is possible to exploit the memoisation effect of DL models to exploit sensitive information about samples, and the original dataset used for training. However, privacy-preserving machine learning (PPML) methods promise to overcome all this issues, allowing to train Machine learning models on "data that cannot be seen".
The workshop will be organised in two parts: (1) in the first part, we will work on attacks to Deep Learning models, leveraging on their vulnerabilities to exploit insights on original (sensitive) data. We will then explore potential counter-measures to work around these issues.
Examples will include cases of image data, as well as textual data where attacks and counter-measures highlight different nuances and corner cases.
(2) In the second part of the workshop, will delve into PPML methods, focusing on mechanisms to train DL networks on encrypted data, as well as on specialised distributed federated training strategies for multiple sensitive datasets.
Part 1: Strengthening Deep Neural Networks (
- Vulnerabilities and Adversarial Attacks
Part 2: Primer on Privacy-Preserving Machine Learning (
- DL training on (Homomorphically) Encrypted Data
- Federated Learning and Intro to Remote Data Science
- Closing Remarks (
Prerequisites and Requirements
This workshop will assume familiarity with PyTorch deep learning framework, and basics of Machine/Deep Learning. No prior specialised knowledge of anonymisations, nor security will be required. Lecture notes will be delivered via interactive Jupyter Notebooks, so the audience should be familiar with the Jupyter environment. However, instructions on how to set up the environment will be shared with delegates beforehand, and prior to the workshop.
