Abstract
Anonymizing location information of a mobile device by an anonymization provider. The anonymizing provider receives, from the mobile device, location information identifying the location of the mobile device and an anonymity requirement. The anonymization provider selects an obfuscation value indicating an extent of location obfuscation that satisfies the received anonymity requirement. The extent of location obfuscation determines location boundaries within which a generated obfuscated location will reside. The anonymization provider generates an obfuscated location for the mobile device and sends the obfuscated location to the mobile device.
