Let's Focus: Focused Backdoor Attack against Federated Transfer Learning

no code implementations30 Apr 2024 Marco Arazzi, Stefanos Koffas, Antonino Nocera, Stjepan Picek

In particular, the proposed attack can be carried out by one of the clients during the Federated Learning phase of FTL by identifying the optimal local for the trigger through XAI and encapsulating compressed information of the backdoor class.
