    Abstract: This disclosure relates to management of privileges associated with applications accessible by users of electronic devices. In one aspect, an electronic device detects that a privilege has been revoked, shuts down any application running on the electronic device that has previously accessed the privilege, and restarts any application that was shut down, the restarted application no longer having any access to the revoked privilege. In another aspect, an electronic device keeps a log of which applications have previously accessed which privileges, receives a new set of privileges associated with applications, determines that a privilege has been revoked, and if the log indicates that an application previously accessed the privilege, resets the electronic device. In a further aspect, a method sets privileges associated with applications, records which electronic devices have which applications, revokes a privilege, and instructs those electronic devices having applications to which the privilege is associated to reset themselves.

    Abstract: A device and method are provided for a device that communicates security information to a user entering content into the device. In an aspect, the device may access content from a server over a connection through the network. The device displays the content on a user interface of the device. The device detects information entered into a field of the displayed content and evaluates a security state of the device. If the security state is below a security threshold and, if the entered information is identified as protected information based on stored criteria, the device displaying a visual indication on the user interface.

    Abstract: A method of identifying a user of a device having a security policy and including a touch sensitive input device. The method includes receiving data corresponding to use of the touch sensitive input device by the user and determining from the received data at least one feature. Based on the at least one feature and a signature associated with an identifiable user, the method determines a likelihood that the user is the identifiable user and modifies, based on the likelihood, the security policy on the device.

    Abstract: 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.

    Abstract: In some data communication configurations, data received from a sender may need to be viewed or otherwise processed by more than one entity with a corresponding client. For example, a message sent to a corporate email address may be viewed by either or both a mobile device and a desktop device. For the sender to utilize the strongest algorithm or protocol used by the recipient, it would therefore need to know which algorithms or protocols are supported by both the mobile and desktop mail clients. A system and method are provided to enable the mobile device to know about the capabilities of related mail clients associated with the communication address (e.g. email address) and vice versa such that the intersection of the capabilities (i.e. the strongest algorithm or protocol supported by all parties involved) can be chosen and the messages or data cryptographically processed accordingly.
