Abstract
A mobile communications device for communicating with a wireless network, including an electronic storage having data stored thereon, a processor connected to the storage for accessing the data, a communications sub-system connected to the processor for exchanging signals with the wireless network and with the processor, a user input interface connected to send user input signals to the processor in response to user action, and a security module associated with the processor for detecting a trigger condition and automatically taking a security action if a bypass user action is not detected after detection of the trigger condition.
Claims17
A mobile communications device for communicating with a wireless network, comprising:
- an electronic storage haying data stored thereon;
- a processor coupled to the storage for accessing the data;
- a communications sub-system coupled to the processor for exchanging signals with the wireless network and with the processor;
- a user input interface configured to send user input signals to the processor in response to user action;
- and
- a security module that configures the processor to:
- monitor for an expiration of a duration of time during which the device has been out of communication with the wireless network;
- and
- upon expiration of the duration of time,
- when a successful user authentication at the device does not occur within a fuse time following the expiration of the duration of time during which the device has been out of communication with the wireless network, perform a security action in which all or part of the data from the storage is at least one of erased and encrypted, and
- when the successful user authentication occurs at the device within the fuse time following the expiration of the duration of time during which the device has been out of communication with the wireless network, continue processing without performing the security action in which all or part of the data from the storage is at least one of erased and encrypted.
A method of providing security for a mobile communication device configured to communicate over a wireless network, the method comprising:
- monitoring for an expiration of a duration of time during which the device has been out of communication with the wireless network;
- and
- upon expiration of the duration of time,
- when a successful user authentication does not occur within a fuse of time following the expiration of the duration of time during which the device has been out of communication with the wireless network, performing a security action in which all or part of the data stored on an electronic storage is at least one of erased and encrypted, and
- when the successful user authentication occurs within the fuse time following the expiration of the duration of time during which the device has been out of communication with the wireless network, continue processing without performing the security action in which all or part of the data from the storage is at least one of erased and encrypted.
A non-transitory computer-readable medium comprising instructions for providing security for a mobile communication device configured to communicate over a wireless network, wherein the instructions, when executed by a processor of the device, configure the processor to;
- monitor for expiration of a duration of time during which the device has been out of communication with the wireless network;
- and
- upon expiration of the first duration of time,
- when a successful user authentication does not occur within a fuse time following the expiration of the duration of time during which the device has been out of communication with the wireless network, perform a security action in which all or part of the data stored on an electronic storage is at least one of erased and encrypted, and
- when the successful user authentication occurs within the fuse time following the expiration of the duration of time during which the device has been out of communication with the wireless network, continue processing without performing the security action in which all or part of the data from the storage is at least one of erased and encrypted.
