Practical Speech Re-use Prevention in Voice-driven Services

no code implementations12 Jan 2021 Yangyong Zhang, Maliheh Shirvanian, Sunpreet S. Arora, Jianwei Huang, Guofei Gu

We present AEOLUS, a security overlay that proactively embeds a dynamic acoustic nonce at the time of user interaction, and detects the presence of the embedded nonce in the recorded speech to ensure freshness.

Beating Attackers At Their Own Games: Adversarial Example Detection Using Adversarial Gradient Directions

no code implementations31 Dec 2020 Yuhang Wu, Sunpreet S. Arora, Yanhong Wu, Hao Yang

Adversarial examples are input examples that are specifically crafted to deceive machine learning classifiers.

Adversarial Light Projection Attacks on Face Recognition Systems: A Feasibility Study

no code implementations24 Mar 2020 Dinh-Luan Nguyen, Sunpreet S. Arora, Yuhang Wu, Hao Yang

While feasible, digital attacks have limited applicability in attacking deployed systems, including face recognition systems, where an adversary typically has access to the input and not the transmission channel.
