    Abstract: A system and method for a privacy mode are disclosed. A trusted execution environment and general operating system that has restricted access to the trusted execution environment are maintained on a processor. A privacy mode command indicating either one of a first value and a second value is received. A peripheral control interface, which is communicatively coupled to the trusted execution environment and otherwise communicatively isolated from the general operating system, is disabled when the privacy mode enable indicator has the first value and is enabled when the privacy mode enable indicator has the second value. An associated peripheral is disabled from providing signals to processing circuits when the peripheral control interface is in the disabled state and enabled to provide signals to processing circuits when the peripheral control interface is in the enabled state.

    Abstract: A method at an electronic device having at least one slot to receive a removable security module, the method including detecting coupling of the security module to the electronic device; sending a challenge to the security module; receiving a response from the security module; checking whether the response is valid at the electronic device; and providing a signal based on results of the checking, wherein only a defined number of security modules are configured to provide a valid response per slot or for each security module type at the electronic device. Further, a method for preventing functionality on an electronic device, the method including replacing a valid security module coupled to the electronic device with a dummy security module; detecting uncoupling of the dummy security module; and providing an alert.

    Abstract: The security of a personal image in an apparently trusted UI is improved through the use of a fingerprint sensor hardwired to a Trusted Execution Environment. The personal image may be a complete or partial representation of a fingerprint sensed by the fingerprint sensor enhanced through emphasis of features of the fingerprint. Alternatively, the personal image may be an object whose movement within the UI is controlled responsive to data received from the fingerprint sensor.

    Abstract: A system and method for supporting encryption key retrieval. A first digital key is created. A first protected key is created by applying a first protection algorithm based on a first user provided password to the first digital key. A first unlock key is created that is separate from the first digital key. A second protected key is created by applying a second protection algorithm based on the first unlock key to the first digital key. The first protected key and the second protected key are stored. The first unlock key is sent to a remote storage and no copy of the unlock key is retained after the sending the first unlock key.

    Abstract: The present disclosure relates to a method and system for managing a meeting session. In accordance with one example, there is provided a method of managing a meeting session on a server that manages the meeting session, the meeting session comprising one or more participant devices and a presenter device. The method comprises receiving one or more break request messages from the participant devices, and sending a break message to the participant devices, the break message causing a break notification to be displayed on a display of the participant devices.

    Abstract: Systems and methods of owner application control of an electronic device are provided. Owner application control information is stored on the electronic device and/or one or more remote servers. Owner application control information is consulted to determine if one or more required applications are available for execution on the electronic device. If not, one or more required applications not available are downloaded and installed. This could be in a manner transparent to the user of the electronic device. If one or more required applications are not available on the electronic device, the device can be functionally disabled in whole, or in part, until one or more required applications are available.

    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.
