Location obfuscation is a technique used in location-based services or information systems to protect the location of the users by slightly altering, substituting or generalizing their location in order to avoid reflecting their real position.
A formal definition of location obfuscation can be "the means of deliberately degrading the quality of information about an individual's location in order to protect that individual's location privacy.
Obfuscation techniques
The most common techniques to perform this change are:
Pseudonyms and the use of third party location providers
"Spatial cloaking" techniques in which a user is k-anonymous if her exact location cannot be distinguished among k-1 other users
"Invisible cloaking", in which no locations are provided for certain zones
Adding random noise to the position
Rounding, which uses landmarks to approximate the location
Redefinition of possible areas of location.
Each technique for obfuscating location has strengths and weaknesses, and it is important to assess them based on each use case. For example, adding random noise is simple to implement, but can inadvertently create a circle of obfuscated values where the center reveals the individual's exact location. One should also consider the level of obfuscation required in urban areas versus rural areas.

Location Obfuscation for Location Data Privacy - IEEE Xplore
Jun 27, 2015 · This study proposes various methods of location obfuscation for GPS location data which are used to obfuscate user's path and location from service provider. Our work shows that user privacy can be maintained without affecting LBSs …
On the Anonymization of Differentially Private Location …
We evaluate the anonymity of the location data obfuscated by two location obfuscation mechanisms: PL (the planar Laplacian mechanism) and OptQL (the optimal geo-indistinguishable mechanism). We empirically show that OptQL satisfies stronger anonymity than PL. We propose the notion of ( ; )-asymptotic anonymity,

One technique to protect the location is called Location Obfuscation, which consists in non reversible ways to slightly alter the location such that it does not reflect the real location of the user, but still contains enough information to provide a satisfactory service.
Matlock: A location obfuscation technique for accuracy-restricted ...
In this work, a light-weight and fully reversible location obfuscation technique named Matlock is presented. Matlock, based on matrix obfuscation, requires low computation per operation and hides the location in both spatial and temporal dimensions.
