METHOD AND APPARATUS FOR PROTECTING DATA IN A PORTABLE ELECTRONIC DEVICE
Data in a portable electronic device is protected by using external and internal status detection means to determine if the device is misplaced, lost, or stolen. The device then takes, singly or in combination, one of several actions to protect the data on the device, including declaring its location to an owner or service provider, locking the device or specific functions of the device to disable all data retrieval functionality, erasing or overwriting all the stored data in the device or, where the data has been stored in the device in an encrypted format, destroying an internally-stored encryption key, thereby preventing unauthorized access to the encrypted data in the device.
1 . A method for actuating a portable electronic device, the method comprising executing software embodied on the portable electronic device which causes the portable electronic device to perform the steps of:
receiving an intended operation region,
calculating a current position of the portable electronic device,
determining a status of the portable electronic device when the position is outside of the intended region; and
triggering an action in response to the determined status.
2 . The method of claim 1 , wherein the step of determining the current position of the portable electronic device is based on WiFi triangulation.
3 . The method of claim 1 , wherein the step of determining the current position of the portable electronic device is based on RFID.
4 . The method of claim 1 , wherein the triggered action comprises locking the portable electronic device.
5 . The method of claim 1 , wherein the triggered action comprises sounding an audible alarm of the portable electronic device.
6 . The method of claim 1 , wherein the triggered action comprises the portable electronic device executing a call to a predetermined number and audibly reporting a location of the portable electronic device over the call.
7 . The method of claim 1 , further comprising triggering at least two actions, wherein a first action comprises transmitting the location to the website accessible by the authorized user of the portable electronic device, and a second action comprises locking the portable electronic device.
8 . The method of claim 1 , further comprising triggering at least two actions, wherein a first action comprises transmitting the location to the website accessible by the authorized user of the portable electronic device, and a second action comprises sounding an audible alarm of the portable electronic device.
9 . The method of claim 1 , further comprising triggering at least two actions, wherein a first action comprises transmitting the location to the website accessible by the authorized user of the portable electronic device, and a second action comprises erasing stored data in the portable electronic device.
10 . The method of claim 1 , further comprising triggering at least two actions, wherein a first action comprises transmitting the location to the website accessible by the authorized user of the portable electronic device, and a second action comprises destroying an encryption key associated with data of the portable electronic device.
11 . The method of claim 1 , wherein the status indicates that the portable electronic device is misplaced, lost, or stolen.
12 . The method of claim 1 , wherein the step of determining the status of the portable electronic device further comprises comparing usage data of the portable electronic device with predetermined usage data parameters.
13 . The method of claim 1 , wherein executing software embodied on the portable electronic device comprises causing the portable electronic device to trigger at least three actions in response to the determined status.
