This project aims to explore privacy preserving approaches applied to machine learning. The set of explored techniques encompasses homomorphic encryption, differential privacy, secure multi-party computation and trusted execution environments.
I’m interested in both the training and inference aspects with the aim to deploy machine learning models that could safely interact with sensitive data.
One of my current focus is the interaction between blockchains and federated learning to provide privacy-preserving audit trails and secure aggregation mechanisms.
