Abstract: A key management system for providing encryption of a disk in a client device is provided. The system comprises a trusted platform module (TPM) having a first fragment of a key, a remote storage having a second fragment of the key, and a processing unit to partially boot instructions relating to the booting of the client device, send a request for validation of the instructions to the TPM, receive the first fragment of a key from the TPM if the validation is successful, send a request for the second fragment of the key along with credentials to access the remote storage. The remote storage verifies the credentials and a network through which the request is received and transmits the second fragment if the verification is successful. The processing unit then combines the first fragment and second fragment of the key to generate an encryption key which is used to complete the booting.

Abstract: A system provides automated transitions between presenters of a communication session. During a meeting, a system can provide a user interface that includes a primary presenter region configured to display a rendering of a presenter and the presenter's shared content. The user interface can also provide an audience region, which may include a number of individual video streams of audience members arranged in virtual environment. When the system determines that an individual audience member raises their hand, the system generates a graphical notification indicating that the person raised their hand. The system can also automatically add that individual audience member to a presenter queue. When the first presenter completes their presentation, the system can automatically transition the user listed in the presenter queue to the primary presenter region or a secondary presenter region. The system can also automatically change permissions for users that initiate a transition to a presenter role.
