Abstract: Presented are systems and methods for providing moderator control in a heterogeneous conference including activating a secure workgroup sharing system between an organizing mobile device and one or more invitee mobile devices, such that activating the secure workgroup sharing system generates a secure workgroup invitation. The secure workgroup sharing system sends the secure workgroup invitation and a security key to one or more invitees associated with the one or more invitee mobile devices. The secure workgroup sharing system receives a security key, matching the sent security key, and an acceptance of the secure workgroup invitation from at least one of the one or more invitee mobile devices, and establishes a peer-to-peer workgroup allowing direct secure communications between the organizing mobile device and at least one of the one or more invitee mobile devices.
