Yeah, HDCP (high-definition copy protection) makes an attempt to make content viewable, but not copyable, but it only works by certifying every single piece of the chain and it&#x27;s still vulnerable to someone using a simple video camera to capture images of the displayed message.<p>Barring a human-computer interface that conveys messages directly into someone&#x27;s brain, I don&#x27;t see this as possible. If you can see it or if you can hear it, then it is copy-able.
