Illustration of the false positive detection. (a) Watermarked image, (b) embedded watermark, (c) extracted watermark with correct information, (d) extracted watermark from (a) by using of watermark (WM2), (e) extracted watermark from (a) by using of watermark (WM3), and (f) extracted watermark from an arbitrary image by using the information of images given in (a) and (b).
