Topic: 

  Joint communication and sensing: signal surveillance threats

 

Abstract: 

  High-accuracy radio positioning technologies are critical for many personal and smart city applications, such as tracking patients in hospitals, recognizing behaviors in augmented reality, UAV path planning, and locating victims in emergency calls. These techniques are expected to be the core technologies of the sixth-generation (6G) networks. However, they could be exploited to monitor a user's activities and habits and work as see-through wall tools, leading to a potential violation of individual rights. In this talk, we first discuss state-of-the-art radio positioning techniques. And then, we demonstrate several cases of tracking without user consent in a restricted access building through a novel AI-empowered radio-based indoor surveillance method. Experimental results show that the threat of monitoring a target user with up to centimeters of accuracy is real, even without the physical intrusion of the attacker. Given the vision of joint communication and sensing in 6G networks and generative AI tools, we highlight the challenges and specific topics to protect the right to be forgotten (user privacy) and prevent surveillance efforts in wireless-related technologies. Besides, potential topics for industry-academia cooperation and ISAC-6G security in six core strategic industries are also presented.
