Claim 0:
1. A method for monitoring and correcting obfuscation of vehicle-related data transmitted to a backend computer with an anonymization filter, comprising:
removing personal data from the transmitted vehicle-related data;
combining the vehicle-related data, after removing the personal data, to obtain a vehicle-related data set without personal information;
temporally and spatially obfuscating the vehicle-related data set without personal data based on an estimated cluster size of data-collecting vehicles to generate an anonymous data set;
sending the anonymous data set, including a degree of obfuscation, to a data user;
determining an actual cluster size for a spatial region based on the anonymous data set;
comparing the determined actual cluster size with the estimated cluster size for the obfuscation of the anonymous data set; and
correcting the obfuscation of the spatial region, based on the results of the comparison of the actual cluster size with the estimated cluster size.
