Authentication for over the top broadcast streaming using automated content recognition

This invention describes a way to authenticate a second device, like a phone, for streaming content by having it listen to or watch media playing on a primary device, such as a TV. The second device captures a snippet of the audio or video, sends it to a server, and the server uses content recognition, specifically by generating a unique 'fingerprint' of the snippet, to confirm it matches the original stream. If there's a match, the second device is authenticated to view the content.
