Speech privacy-preserving methods using secret key for convolutional neural network models and their robustness evaluation
Shoko Niwa, Sayaka Shiota, Hitoshi Kiya
In this paper, we propose privacy-preserving methods with a secret key for convolutional neural network (CNN)-based models in speech processing tasks. In environments where untrust…
