Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose an image classification method for compressible encrypted images without losing classification accuracy. First, we train a vision transformer (ViT) model by using plain images. The trained ViT model is then encrypted with a key. In contrast, test images are supposed to be encrypted with an encryption-then-compression method with the same key as that used for encrypting the model. Accordingly, the proposed method also protects the trained model so that only authorized users can utilize the performance of the model.
