Positioning System

Watch Professor Hosung Jo discuss positioning systems' role in smart cities, balancing high accuracy with critical privacy and data security risks.

Modern life and smart cities depend on complex positioning systems that blend satellites (GPS/GNSS), wireless networks (Wi-Fi/Bluetooth), and on-device AI sensors to deliver highly accurate location data for applications like autonomous driving, logistics, and emergency services. This utility, however, is undermined by significant vulnerabilities: signals are susceptible to jamming and spoofing, and the resulting massive collection of sensitive location logs creates major threats to citizen privacy and security. The key to sustaining the benefits of these hybrid systems is increasing transparency, resolving accuracy issues with advanced technology like 5G, and implementing robust safeguards to ensure public trust.

What you will learn in this video:

  • What makes hybrid positioning systems accurate and essential
  • Why jamming, spoofing, and location tracking threaten security and privacy
  • How transparency and technology upgrades build public trust
