WebJan 13, 2024 · 4.7 Mixed Label Noise Data. We verified the attack effect of noisy data under the same specification as that for mixed-labels reconstructed data, which is to use 1 noisy data for each label, a total of 10 data to attack the model. The results are shown in Fig. 9. The accuracy of the original model on specific label and total data is around 98%. WebNext, we present a full database reconstruction attack. Our algorithm runs in polynomial time and returns a poly-size encoding of all databases consistent with the given leakage profile. We implement our algorithm and observe real-world databases that admit a large number of equivalent databases, which aligns with our theoretical results.
