Interconnect device to enable compliance with rights management restrictions
First Claim
1. A method for authenticating a watermark comprising:
- receiving, at a source device, a watermark authentication request comprising watermark information corresponding to a digital watermark detected in media content by an interconnect device, wherein the interconnect device sends the watermark authentication request;
determining, at the source device, whether the digital watermark is authentic based on the watermark information; and
sending, from the source device, an authentication response indicative of whether the digital watermark is authentic.

Abstract
To help ensure that only authorized media content that is associated with rights management (RM) restrictions is delivered from a compliant RM interface of a source device to a non-compliant RM interface of a destination device, an interconnect device provides a compliant RM interface to connect to the source device and monitors media content received from the source device to detect an embedded digital watermark. The interconnect device takes the necessary steps to determine if the watermark is authentic and control delivery of the media content to the destination device accordingly. The interconnect device may go back to the source device or to a remote service to authenticate the watermark. If the watermark is authentic, the media content is passed by the interconnect device to the non-compliant interface of the destination device outside of normal RM restrictions. Otherwise, the delivery of the media content is restricted by the interconnect device.
