Automatic security action invocation for mobile communications device

摘要

A mobile communications device, method, and computer program product for providing security on a mobile communications device are described. In accordance with one example embodiment, the mobile communications device comprises: a processor; a communications subsystem connected to the processor operable to exchange signals with a wireless network and with the processor; a storage element connected to the processor and having a plurality of application modules and data stored thereon, the data comprising at least user application data associated with the application modules and service data including data for establishing communications with the wireless network; and a security module operable to determine if a battery level falls below a predetermined threshold and perform a security action comprising erasing or encrypting at least some of the data on the storage element if the battery power falls below the predetermined threshold.

主权项

1. A method for providing security on a mobile communications device, the method comprising:
forcing the mobile communications device into a locked state, regardless of any current user input activity and regardless of wireless network coverage, upon expiry of periodic timeout periods, each timeout period having a first duration; detecting, by a communications subsystem of the mobile communications device, prior to expiry of a particular timeout period of the periodic timeout periods, a lack of wireless network coverage for a second duration that is shorter than the first duration; and responsive to detecting the lack of wireless network coverage for the second duration, forcing the mobile communications device into the locked state prior to the expiry of the particular timeout period, regardless of any current user input activity, thereby shortening the particular timeout period from the first duration to the second duration.
