Method and system for performing transcoding resistant watermarking

A method for performing transcoding resistant watermarking of digital media content, the method comprising:

• obtaining a plurality of spectral frequency bands of the digital media content;
• calculating a first metric for each of the plurality of spectral frequency bands, wherein the first metric quantifies information in each of the plurality of spectral frequency bands;
• determining a second metric in the digital media content, wherein the second metric represents high feature density regions in the media content;
• identifying high information regions in the digital media content using at least one of:
• the first metric and the second metric;
• and
• inserting a watermark in the identified high information regions in the digital media content.

A system for performing transcoding resistant watermarking of digital media content, the system comprising:

• a high information region determining module in communication with a processor and configured to determine high information regions in the digital media content based on at least one of:
• a first metric and a second metric;
• and
• a watermark insertion module in communication with the processor and configured to insert a watermark pattern in the determined high information regions of the digital media content.
