Instance-wise Batch Label Restoration via Gradients in Federated Learning

ICLR 2023poster

Gradient inversion attacks have posed a serious threat to the privacy of federated learning. The attacks search for the optimal pair of input and label best matching the shared gradients and the search space of the attacks can be reduced by pre-restoring labels. Recently, label restoration technique…
