  • Patent number: 8370431
    Abstract: A network meeting application for providing network meetings, such as web conference meetings, runs on a presenter device. In response to a request for a network meeting from an attendee device, the presenter device creates a secure desktop separate from a working desktop. The presenter may use the secure desktop to share documents, presentations, or other applications with the attendee device. The attendee device is blocked from accessing the working desktop of the presenter device. A presenter using the presenter device may switch between the working desktop and the secure desktop. Security policies, downloaded to the presenter device from a server, determine the applications the attendee may run on the secure desktop. The secure desktop thereby protects the integrity of the presenter's working desktop during a web conference meeting, while allowing documents, presentations, or other applications to be shared with attendees via the secure desktop.
