Abstract(in English) | With the increasing scale of data, integrated analysis of data distributed to multiple institutions is required. On the other hand, collecting data from multiple institutions often involves privacy risks, and there is a methods called anonymization as a representative measure. In this research, we improve Model Inversion Attack, which is one of attacks against models, and propose the attack method against anonymized data which we call Data Inversion Attack. In the evaluation, the data that has been pk anonymized and matrix decomposition anonymized that can handle high-dimensional data is targeted, and the restoration of the original data is evaluated quantitatively. In particular, using the distribution of the original data as a baseline, we have shown that our attack method can contribute to restoration of anonymized data with higher accuracy than the baseline. |
