System and method of preventing alteration of data on a wireless device
First Claim
1. A system for securing data, comprising:
- at least a wireless device; and
a data processing system, coupled to said at least a wireless device, wherein said data processing system disables said at least a wireless device in response to determining that an emitted signal strength of said at least a wireless device is less than a first predetermined value for greater than a period of time represented by a second predetermined value.

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.
