Title：security and privacy in intelligent voice systems Abstract： Integrating AI and IoT technologies has endowed intelligent voice systems with powerful cognition capabilities and natural interaction experience. Behind the bright prospect of AIoT-enabled intelligent voice systems, the shadow of security and privacy threats is also enlarged due to the endogenous vulnerability of AI and the natural openness of IoT. This talk explores the frontiers of security and privacy issues in intelligent voice systems, covering real-world malicious injections and non-intrusive speech sanitization. The malicious injections emit side-channel magnetic signals for stealthy command activation, and even directly deliver acoustic perturbations for real-time speaker impersonation. The speech sanitization is also highlighted, exploring the use of inconspicuous ultrasound and adversarial perturbation designed to obfuscate linguistic content and voiceprint, ensuring privacy-preserving speech communication. In this talk, we will elaborate on advancements in this field and report the latest results of our team. We will delve into the security and privacy issues of intelligent voice systems and their role in facilitating the trustworthy and sustainable development of AIoT. |
