Claim 0:
1. A method comprising:
establishing, by a video conferencing system, a first session with a first participant user device of a participant to be included in a video conference;
establishing, by the video conferencing system, a second session with a second participant user device of the participant included in the video conference that is physically separate from and proximate to the first participant user device;
transmitting, by the video conferencing system via the first session, modulated data to the first participant user device, wherein the modulated data is to be projected onto a face of the participant by the first participant user device;
receiving, by the video conferencing system via the second session, a video stream associated with the participant from the second participant user device, wherein the video stream includes a reflected version of projected and modulated data that is captured by the second participant user device as the face reflects the projected and modulated data;
analyzing, by the video conferencing system, the reflected version of the projected and modulated data that is derived from the received video stream by comparing the reflected version of the projected and modulated data received from the second participant user device with the modulated data transmitted to the first participant user device;
conditionally detecting, by the video conferencing system, the modulated data in the video stream if the reflected version of the projected and modulated data received from the second participant user device matches the modulated data transmitted to the first participant user device within a threshold similarity level based on the analyzing; and
maintaining, based on the conditionally detecting, the second participant user device in the video conference.
