Abstract
The present invention leverages a series of media watermark locations to provide information relating to media ownership and/or distribution source. This provides a forensic means to establish a source of media with a high degree of certainty despite malicious and/or non-malicious attacks. By providing embedded user unique identification, a source of copied media can be determined without the embedded information substantially interfering with the intended purpose of the media itself. In one instance of the present invention, digital media is transformed into an N-dimensional media signal. User unique keys are then utilized along with a master key to determine locations for embedding a watermark signal that possesses substantially similar quantized statistics as the transformed media signal. The watermark signal is then embedded into the media signal, fingerprinting the media.
