Abstract (in Japanese) (See Japanese page) 
(in English) Adversarial examples cause misclassification of image classifiers. Higashi et al. proposed a method to detect adversarial examples by applying noise reduction filters of different strengths to input images and observing changes in the output of the image classifier. This method used 14 different filters, which was computationally expensive. In this paper, we propose a method that demonstrates high detection accuracy with a small number of filters. Based on Higashi et al.'s report, JPEG compression is considered to be a suitable filter for denoising adversarial noises. In the proposed method, a distortion signal created from the difference of images before and after JPEG compression is used as a denoising filter.
