Digital watermarking

A non-transitory computer-readable medium storing instructions which, when executed by a processing system including at least one processor, cause the processing system to perform operations, the operations comprising:

• obtaining a signal containing a media;
• inserting a first digital watermark in a first frame of the media;
• inserting a second digital watermark in a second frame of the media, wherein the second digital watermark differs from the first digital watermark in at least one way comprising at least one of:
• a number of bits of a noise, wherein the noise obfuscates the first digital watermark in the first frame and the second digital watermark in the second frame;
• and
• outputting a watermarked signal containing the media including the first digital watermark in the first frame and the second digital watermark in the second frame.
