First Claim
1. A method for maintaining security of a device, the method comprising:
- monitoring for a heartbeat signal via the device;
if the heartbeat signal is detected, allowing operation of the device; and
if the heartbeat signal is not detected within a predetermined amount of time, determining an appropriate action to take, taking an appropriate action comprising at least one of;
requesting authorization to allow operation of the device;
ordisabling at least one function of the device; and
if the appropriate action comprises requesting authorization to allow operation of the device;

Abstract
Security of a device, such as a mobile device, is maintained via a heartbeat signal. As long as the heartbeat signal is detected, the device is allowed to perform operations. If the heartbeat signal is not detected, appropriate action is taken. Appropriate action can include powering down the device, restricting access to files, erasing files, erasing the contents of a disk on the device, preventing access to designated files, reporting the location of the device, and/or preventing the device from being turned on after it is turned off. In an example configuration, the heartbeat signal is a low-power consuming, low data rate, signal allowing for processing of the heartbeat signal to be accomplished, at least in part, via the SIM of the device.
