An Efficient Dummy-Based Location Privacy-Preserving Scheme for Internet of Things Services
With the rapid development of GPS-equipped smart mobile devices and mobile computing, location-based services (LBS) are increasing in popularity in the Internet of Things (IoT).Although LBS provide enormous benefits to users, they inevitably introduce some significant privacy concerns.To protect user privacy, a variety of location privacy-preservin
