- Abstract: With the ubiquitous use of location-based services, large-scale individual-level location data has been widely collected through location-awareness devices. The exposure of location data constitutes a significant privacy risk to users as it can lead to de-anonymisation, the inference of sensitive information, and even physical threats. Geoprivacy concerns arise on the issues of user identity de-anonymisation and location exposure. In this survey, we analyse different geomasking techniques that have been proposed to protect the privacy of individuals in geodata. We present a taxonomy to characterise these techniques along different dimensions, and conduct a survey of geomasking techniques. We then highlight shortcomings of current techniques and discuss avenues for future research.

Data with privacy concerns comes with stringent regulations that frequently prohibited data access and data sharing.
Overcoming these obstacles is key for technological progress in many real-world application scenarios that involve privacy sensitive data.
Differentially private (DP) data publishing provides a compelling solution, where only a sanitized form of the data is publicly released.
