Method for trust binding and enrollment to secure trust domains

Abstract

An improved method is provided methods for passively binding one or more devices into a security trust domain through audio signals transmitted from a trust-facilitating service and enable media playback of protected digital content on the one or more devices. The method may include receiving, from the trusted device, an audio signal, where the audio signal includes embedded access information configured to enable access to protected content from the one or more devices. As such, the one or more devices may decrypt, decode, or both, the access information from the audio signal and gain access to the protected digital content.
