Patent ID: 7602936

Claim:
A system for embedding a watermark in a set of at least one presentation data frames, comprising: a reversible mapping function for transforming a signal between a first domain and a second domain; a set of at least one original visual presentation frames transformable between the first domain and the second domain, the set of at least one original visual presentation frames having visual presentation content presentable in the first domain; a geometric watermark pattern transformable between the first domain and second domain, said geometric watermark pattern representing a simple identifiable pattern in the first domain and a complex pattern in the second domain; a watermark signal, said watermark signal representing data other than the visual presentation content; a combined watermark pattern, said combined watermark pattern formed from said watermark signal combined with said geometric watermark pattern and transformed to the second domain by the reversible mapping function, wherein the combined watermark pattern is added to an absolute value of wavelet coefficients of the visual presentation content in a bipolar wavelet band; a processor to form a set of at least one final visual presentation frames, the set of at least one final visual presentation frames formed with the set of at least one original visual presentation frames of the first domain and the combined watermark pattern of the second domain.
