Abstract
A mobile device may communicate with a location server during location based services (LBS) operations using a secure identifier. The secure identifier abstracts identification information of the mobile device and/or identification information of a user of the mobile device in instances that the mobile device and/or user identification information are deemed protectable from the location server. The location server may be operable to store location data corresponding to the mobile device and/or the user in a location reference database based on the secure identifier. The secure identifier may comprise a unique value, which may be randomly generated. The secure identifier may also be generated based on the mobile device and/or user identification information, by applying, for example, encryption algorithms to the mobile device and/or user identification information. Service providers for the mobile device may retrieve the abstracted mobile device and/or user identification information from the secure identifier.
