Claim 17:
18. The method according to claim 17, wherein determining the actual cluster size, comprises:
randomly selecting an initial anonymous data set;
collecting other anonymous data sets after an initial anonymous data set is selected for a predetermined time interval, wherein the subsequent data sets relate to the region of the initial anonymous data set;
determining the actual cluster size by determining a number of anonymous data sets within the predetermined time interval for the spatial region predefined by an obfuscated position of the initial anonymous data set;
comparing the actual cluster size with the estimated cluster size determined by a degree of obfuscation for the initial data set; and
correcting obfuscation of the anonymization filter for the predefined spatial region based on the comparing of the actual cluster size with the estimated cluster size.
