US Patent 10104181 Secure context-based group collaboration and communication

A computing device can be utilized to submit content to a collaboration service for posting on a collaboration channel. In response to receiving a posting request, the collaboration service identifies a context associated with the request. The context might include the location of the computing device submitting the request, the authenticated identity of the user submitting the request, or access rights associated with the content to be posted. The collaboration service can utilize the context to identify one or more collaboration channels to which the content can be posted. The user might be permitted to select one or more of the identified channels. Once the content has been posted to the selected channel, or channels, the collaboration service can utilize the context to perform other actions such as, but not limited to, initiating a communications session between authorized users of the collaboration channel to which the content was posted.
