ABSTRACT:
A method for robust embedding of information into video content, said method comprising of breaking said video content into a series of at least one unit; selecting at least one of said units; selecting at least one parameter for at least one of said units and performing at least one geometric transformation on said selected units according to said parameters selected for said unit, thereby to embed said information in said video content.
