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.

Claims

1. A method for authenticating a watermark comprising:

receiving a watermark authentication request comprising watermark information corresponding to a digital watermark detected in media content by an interconnect device;

determining whether the digital watermark is authentic based on the watermark information; and

sending an authentication response indicative of whether the digital watermark is authentic.

2. The method as recited in claim 1, wherein the watermark authentication request is directly received from the interconnect device.

3. The method as recited in claim 2, wherein the authentication occurs remotely from the interconnect device.

4. The method as recited in claim 1, wherein the watermark authentication request is directly received from a source device.

5. The method as recited in claim 4, wherein the authentication occurs remotely from the source device.

6. An authentication server comprising:

a communication interface; and

a processor associated with the communication interface and configured to;

receive a watermark authentication request comprising watermark information corresponding to a digital watermark detected in media content by an interconnect device;

determine whether the digital watermark is authentic based on the watermark information; and

send an authentication response indicative of whether the digital watermark is authentic.

7. The authentication server as recited in claim 6, wherein the watermark authentication request is directly received from the interconnect device.

8. The authentication server as recited in claim 6, wherein the watermark authentication request is directly received from a source device.

9. A non-transitory computer readable medium having software comprising instructions for a processor of an authentication server to:

receive a watermark authentication request comprising watermark information corresponding to a digital watermark detected in media content by an interconnect device;

determine whether the digital watermark is authentic based on the watermark information; and

send an authentication response indicative of whether the digital watermark is authentic.
