Optimal Geo-Indistinguishable Mechanisms for Location Privacy
Optimal Geo-Indistinguishable Mechanisms for Location Privacy
We consider the geo-indistinguishability approach to location privacy, and the trade-off with respect to utility. We show that, given a desired degree of geo-indistinguishability, it is possible to construct a mechanism that minimizes the service quality loss, using linear programming techniques. In addition we show that, under certain conditions, such …
