A uniformity-based approach to location privacy

Pericle Perazzo, Gianluca Dini
2015 Computer Communications

Uniform Obfuscation for Location Privacy [chapter]

Gianluca Dini, Pericle Perazzo
2012 Lecture Notes in Computer Science  
As location-based services emerge, many people feel exposed to high privacy threats. Privacy protection is a major challenge for such applications.  ...  Such a model has general applicability and can evaluate the resistance of a generic locationobfuscation technique.
