Semantics-aware Obfuscation for Location Privacy
The increasing availability of personal location data pushed by the widespread use of location-sensing technologies raises a great concern for the safeguard of location privacy for which location privacy-preserving techniques are being investigated. Location privacy is an important requirements of location-based services (LBS). Typically privacy-preserving techniques in LBS are based on the ide...
متن کاملProtecting Location Privacy through Semantics-aware Obfuscation Techniques
The widespread adoption of location-based services (LBS) raises increasing concerns for the protection of personal location information. To protect location privacy the usual strategy is to obfuscate the actual position of the user with a coarse location and then forward the obfuscated location to the LBS provider. Existing techniques for location obfuscation are only based on geometric methods...
متن کاملSemantic-Aware Obfuscation for Location Privacy at Database Level
Although many techniques have been proposed to deal with location privacy problem, which is one of popular research issues in location based services, some limitations still remain and hence they cannot be applied to the real world. One of the most typical proposed techniques is obfuscation that preserves location privacy by degrading the quality of user’s location information. But the less exa...
متن کاملUniform Obfuscation for Location Privacy
As location-based services emerge, many people feel exposed to high privacy threats. Privacy protection is a major challenge for such applications. A broadly used approach is perturbation, which adds an artificial noise to positions and returns an obfuscated measurement to the requester. Our main finding is that, unless the noise is chosen properly, these methods do not withstand attacks based ...
متن کاملPrivacy of Location Obfuscation
There are many results on the possibilities of privacy leak in location-based services, and many remedies have also been suggested. In this paper, we look at this problem from an altogether different perspective claiming that privacy leaks are most likely inevitable for a lot of remedial mechanisms, and therefore it is necessary to provide means to a user to detect such leaks in advance. We spe...
