摘要： The work to be protected is digitized (10) and a baseline watermark is derived (12). A watermark offset vector is created (16) and then stored (18). The offset vector is added to the baseline watermark vector to generate a modified watermark vector (20). The baseline watermark vector is replaced with the modified watermark in the digitized work (22). And, finally, the watermarked work is returned to the original form (24).
