Public defence announcement:

The leakage of location has been a serious concern for everyone. The location can reveal far more than your latitude and longitude. With a little bit of background information, it is easy to infer much sensitive information about you, such as a home address, personal hobbies, workplace or even health status, which could greatly threaten your properties and even life security.

Aiming to prevent the leakage of location, this dissertation focused on the whole lifecycle of location information, from the signal measurements at the access node, and positioning computation at the cloud/edge side to the location consumption at location-based service (LBS) providers. It identifies the security threats and potential privacy leakages across the whole lifecycle and provides different solutions to enhance the security of the existing 5G positioning system and its related services.

All the proposed schemes are evaluated with simulations or real-world datasets. The results demonstrate the improvement or the trade-off between security, privacy, integrity and overhead. It is expected that this dissertation can further advance secure and privacy-preserving 5G positioning and its services.
