Abstract

A location sentry system is provided for use within a mobile device. The sentry system can be configured to detect unauthorized attempts to locate mobile devices by monitoring messages passed between the mobile device and the wireless network and/or messages passed between components of the mobile device, and determining that one or more of the messages is/are indicative of an attempt to locate the mobile device. In response to a determination that an unauthorized attempt has been detected, the location sentry can be configured to take one or more actions. For example, the location sentry system could prevent location information from being sent back to the wireless network and/or the location sentry system could cause incorrect information to be sent to the wireless network.
