Abstract
A system and method for securing data on a wireless device. A secured zone is defined by a boundary sensor. A data processing system is coupled to the boundary sensor and a wireless device. If the data processing system detects that the signal strength of the wireless device has fallen below a first predetermined value for longer than a second predetermined value, the data processing system deletes a digital certificate corresponding to the wireless device from memory. Thus, when the wireless device is reintroduced into the secured zone, in response to determining that a digital certificate corresponding to the wireless device is not stored in memory, the disabling module disables the wireless device from operation within the secured zone.
