A Survey of Dummy-Based Location Privacy Protection Techniques for Location-Based Services [PDF]
Sensors, 2022 As smart devices and mobile positioning technologies improve, location-based services (LBS) have grown in popularity. The LBS environment provides considerable convenience to users, but it also poses a significant threat to their privacy.

An Efficient Differential Privacy-Based Method for Location Privacy Protection in Location-Based Services [PDF]
Sensors, 2023 Location-based services (LBS) are widely used due to the rapid development of mobile devices and location technology. Users usually provide precise location information to LBS to access the corresponding services. However, this convenience comes with the

Quantifying Location Privacy [PDF]
2011 IEEE Symposium on Security and Privacy, 2011 It is a well-known fact that the progress of personal communication devices leads to serious concerns about privacy in general, and location privacy in particular. As a response to these issues, a number of Location-Privacy Protection Mechanisms (LPPMs) have been proposed during the last decade.

On the Privacy Implications of Location Semantics [PDF]
Proceedings on Privacy Enhancing Technologies, 2016 Abstract Mobile users increasingly make use of location-based online services enabled by localization systems. Not only do they share their locations to obtain contextual services in return (e.g., ‘nearest restaurant’), but they also share, with their friends, information about the venues (e.g., the type, such as a restaurant or a ...

On-the-Fly Privacy for Location Histograms [PDF]
IEEE Transactions on Dependable and Secure Computing, 2022 An important motivation for research in location privacy has been to protect against user profiling, i.e., inferring a user’s political affiliation, wealth level, sexual preferences, religious beliefs and other sensitive attributes. Existing approaches focus on distorting or suppressing individual locations, but we argue that, for directly protecting ...

Differentially Private Location Privacy-preserving Scheme withSemantic Location [PDF]
Jisuanji kexue, 2021 How to realize more reasonable noise addition in location differential privacy-preserving is a hot topic issue.However,adding the same amount of noise in different locations will result in the decrease of service availability and privacy preservation.To ...

Collaborative Location Privacy [PDF]
2011 IEEE Eighth International Conference on Mobile Ad-Hoc and Sensor Systems, 2011 Location-aware smart phones support various location-based services (LBSs): users query the LBS server and learn on the fly about their surroundings. However, such queries give away private information, enabling the LBS to identify and track users. We address this problem by proposing the first, to the best of our knowledge, user-collaborative privacy ...
