Abstract: Embodiments provide techniques for providing copy protection from capturing a displayed image using one or more camera devices. Embodiments generate a plurality of frames, based on the received image, such that when the plurality of frames are displayed using at least a threshold refresh rate, the displayed plurality of frames appears as the received image when viewed by a user, and the displayed plurality of frames appears as one of a plurality of other images when captured by an image capture device. The plurality of frames are then output for display on one or more display devices configured to use at least the threshold refresh rate.

Abstract: In one embodiment, a method comprises a presenter device controlling a web-based collaboration session with session participants via a collaboration server; receiving by the presenter device a Hypertext Transfer Protocol (HTTP) response from a web server, the HTTP response dynamically generated by the web server according to a presenter context associated with a presenter using the presenter device; the presenter device delegating the presenter context based on sending the HTTP response to the collaboration server for presentation of the HTTP response to the at least one session participant, enabling the at least one session participant to independently control viewing of at least a portion of the HTTP response according to the presenter context.
