A system comprising:

• a receiver device having a receiver processor and a receiver storage;
• a receiver video display operatively coupled to the receiver processor;
• and
• a camera operatively coupled to the receiver processor,
• the receiver processor being configured to execute instructions stored in the receiver storage for carrying out a receiver process comprising:
• receiving, via the camera, a series of video frames generated by a web browser of a streamer device, the series of video frames having an image pattern steganographically hidden therein during playback such that the image pattern is visually imperceptible by a human when the video frames are rendered sequentially;
• analyzing the video frames to locate the image pattern;
• matching the image pattern with a predefined image pattern;
• and
• in response to the matching, displaying, on the receiver video display, information associated with the predefined image pattern.

A non-transient computer program product having instructions encoded thereon that when executed by one or more processors cause a process to be carried out, the process comprising:

• receiving a series of video frames generated by a web browser, the series of video frames having an image pattern steganographically hidden therein during playback such that the image pattern is visually imperceptible by a human when the video frames are rendered sequentially;
• analyzing the video frames to locate the image pattern;
