Abstract: Deep neural network (DNN) is known to be vulnerable to adversarial attacks, where adversarial noise is added to images or speech files so that a target DNN-based system outputs wrong results. Adversarial examples are the content which fools a system. Examples of systems that can be attacked using adversarial examples include face recognition and automatic driving system. Moreover, the DNN training data set could also be poisoned in the situation where the adversary has access to the training database. One of the defense techniques is to detect such adversarial images by observing the outputs of a DNN-based system when noise removal filters are operated. Such operation-oriented characteristics enable us to classify a given image whether it is normal or adversarial. In this talk, I will show state-of-the-art techniques for detecting adversarial examples.
