First Claim
1. A method for preserving privacy within a communication system wherein a location-based service concerning an area of interest is provided for at least one user by a database server and wherein location information represented by coordinates of objects and/or users and/or areas and/or queries, made to the location-based service, is concealed, comprises:
- concealing the location information by transforming coordinates by;
first splitting the area of interest up in tiles for providing at least one tiling of the area of interest, andthen permuting the tiles by a pseudo-random permutation process.
