摘要:
The present automatic update mechanism provides a method for periodically checking for updates to support a trusted environment. During the periodic check, an indication from an update service is received if there is a recommended update. Upon receiving the indication, a new revocation list is downloaded from the update service and saved as a pending revocation list. The pending revocation list is then available for on-demand update when protected content requests a higher level of protection on a computing device than the protection provided by a current level of protection on the computing device.

Various technologies for managing mobile device communications can be offered to implement a virtual personal operator. Incoming calls and texts can be managed intelligently based on a rich network-stored context, allowing the network to make decisions and interact with callers. Because context is stored by the network, the virtual personal operator can function without contacting the called mobile phone, and can even provide helpful information to callers if the mobile phone is offline. Rich do-not-disturb functionality can be provided, and privileged callers can be given additional information or functionality based on their privileged status. Numerous other features that assist with communications management can be supported.

Methods and apparatuses are provided for use in authenticating credential information and allowing such credential information to be exchanged over non-secure channels in a safe and protected manner.
摘要:
The present automatic update mechanism provides a method for determining whether computer-readable components loaded within a memory device are at a level of protection specified for protected content that a media application is attempting to process. If a current level of protection provides lower protection that the level specified, a file is updated to achieve at least the level of protection specified by the protected content. Updating the file to achieve the level of protection is performed in a manner that minimizes rebooting of a computing device.
摘要:
A method of establishing a protected environment within a computing device including validating a kernel component loaded into a kernel of the computing device, establishing a security state for the kernel based on the validation, creating a secure process and loading a software component into the secure process, periodically checking the security state of the kernel, and notifying the secure process when the security state of the kernel has changed.
摘要:
Systems and methods for providing a protected computing environment comprising separating out a protected environment management component from a kernel of a computing device, providing identification information as a part of the protected environment management component, and providing individualization information as part of the protected environment management component.
摘要:
A system and method is provided for allocating video bandwidth of a channel that carries both video and audio information. The quality of an audio signal received over the channel is determined, and the video bandwidth of the channel is changed based upon the quality of the received audio signal. The quality of the audio signal can be determined by measuring factors including audio latency, the extent to which audio packets that are sent are not received, the sampling rate at which audio information in the audio signal is digitized, and detecting a period of audio silence.
