Title: Threat and Protection on Image-Based Deep Learning

Abstract: In recent years, a series of researches have revealed that Deep Neural Network (DNN) is vulnerable to adversarial attack, and a number of attack methods have been proposed. Among those methods, an extremely sly type of attack named one-pixel attack can mislead DNNs to misclassify an image via only modifying one pixel of the image, leading to severe security threats to DNN-based information systems.
My work reveals the internal threat of one-pixel attack and proposed two detection methods, including trigger detection and candidate detection, that filled the blank of no method can really detect one-pixel attack.
The trigger detection method analyzes the vulnerability of DNN models and gives the most suspected pixel that is modified by one-pixel attack.
The candidate detection method identifies a set of most suspected pixels using differential evolution-based heuristic algorithm.
