Abstract: A method and system for managing delivery of a content stream to a plurality of devices participating in an online conference session, including delivering, to each of the devices, the content stream associated with the online conference session at a first signal quality, receiving an indication signal indicating that a first device is to broadcast the content stream, responsive to the indication signal, increasing a signal quality of the content stream delivered to the first device from the first signal quality to a second signal quality, wherein the second signal quality is higher than the first signal quality, delivering the content stream to the first device at the second signal quality, and delivering the content stream to the rest of the devices at the first signal quality or a third signal quality, wherein the third signal quality is lower than the first signal quality.

Abstract: A system can control access to encrypted data shared by a group of users by the use of a vault key that is associated with a group of users. The encrypted data can include encrypted secret data generated from the secret data using a secret key, an encrypted secret key can be generated from the secret key by the use of a vault key, and an encrypted vault key generated from the vault key by the use of a public key associated with a user of the group of users. The system can allow users to store and access the encrypted data only if the user is a current member of the group. The system can verify the user's membership status from a group manager, such as a system managing a channel or chat session. Users added to the group are also granted permission to grant access to new users.

Abstract: This disclosure provides enhanced management of access rights for dynamic groups of users sharing secret data. Instead of relying on traditional administrative techniques for modifying access rights for stored data, the techniques disclosed herein allow a storage service to communicate with a group management system to verify membership of user groups, e.g., channels, chat session, or meetings, and automatically change access rights to stored data as users leave or join a group. Encrypted data can be stored within a storage vault. The storage vault can be dedicated to storing encrypted data shared between a user group, e.g. a channel. A server managing the storage vault can receive membership data from a group management service. As users join the group or leave a group managed by the group management service, each user's access permissions to the storage vault can be added, removed or modified.

Abstract: This disclosure provides enhanced management of encryption key updates based on user group activity. A system utilizes a vault key and a combination of other security keys to control access to secret data shared by members of a group who are participating in a collaborative session, such as a channel or chat session. The vault key allows a system to control access to secret data with users that join a particular group while immediately restricting access from users that leave the group. Updates to the keys are initiated based on the activity of the members of a group, which can include, but is not limited to, a threshold change in a number of group members, a total number of group members, an amount of data shared between the group members, and/or an age of one or more keys used to secure data shared by the group.

Abstract: A device may be configured to enable a user to select a language, and may fulfill resource requests from applications by selecting, from among resources respectively associated with a language, a resource associated with the selected language of the user. However, this resource selection process may be inadequate if the user selects multiple languages; if a resource associated with the selected language of the user is unavailable, but resources associated with related languages are available; or if the user and/or the application specifies an ordering for the selection among the languages. Presented herein are techniques for performing the resource selection by, for respective languages selected by the user, calculating a weight representing a suitability of the language for the resource request; generating a selection order of the selected languages according to the weights; and selecting a resource based on the position of the associated language in the selection order.

Abstract: Language selection and application within a computing environment are often distributed over and differently applied by the operating system and various applications, leading to additional administration, inconsistencies in the user experience based on different language feature implementations among different applications; and increased cost and redundancy in developing language features for different applications. Presented herein are techniques for configuring a device with an application language library that centralizes the selection of languages by the user, and that provides a wide variety of language features (e.g., text translation, user interface adaptation, and data formats) to the applications and operating system.
