报告简介

In the new AI era (or equivalently in the “Fake News” era), seeing will no longer be believing and even truth will not be believed. People can easily manipulate digital images or generate highly visually convincing fake images and videos, and therefore pose critical challenges in digital image forensics (DIF) analysis. Deep learning has been widely employed for DIF tasks. Unfortunately, both digital images and deep learning models are vulnerable to manipulations and attacks, intentionally or unintentionally. This talk gives a brief review of my group’s recent research efforts in the intersection of deep learning and DIF -- adversarial deep learning, with focus on adversarial attacks. We consider potential adversarial attacks and explore novel approaches to study vulnerabilities of deep learning models, by investigating three fundamental learning tasks: matching, classification and regression. We present novel attacks (both in the digital domain and physical domain) for several essential models (e.g., fake face imagery forensics; camera-LIDAR 3d object detection; and single object tracking in videos). Potential future directions in achieving more trusting deep learning solutions for trusting digital images will also be discussed.
