Oh dearie me.
What a snake oil promise. Guys, once that image is seen, you can't stop it being kept. All that will be need will be an initial viewing, and then that image has been decoded. How you going to keep the decoded image out of the browser cache, eh? Are you going to reconnect every time the page redraws - if so, that'll really slow down the browser? How do you stop someone capturing it when they can see it?
I really can't see this one flying, somehow.
