Privacy-Preserving Location Assurance Protocols for Mobile Applications
Location-based applications require a user's location data to provide customized services. However, location data is a sensitive piece of information that should not be revealed unless strictly necessary which induces the emerging of a number of location privacy protection methods, such as anonymity and obfuscation. However, in many applications, one needs to verify the authenticity and other properties (e.g. inclusion to an area) of location data which becomes an intractable problem because of the using of location privacy protection.
