PM: simplified, changed ‘’negative’’ wording to focus on properties of a ‘’good’’ watermarking technology; only refer to imperceptible (no visible overlays); focus on video (not audio); changed ‘’still image’’ challenges to ‘’video’’ challenges; changed the watermark pattern from ‘’JP2K multi-resolution encoding’’ to something more ‘’neutral’’ wrt watermarking method.
PM: do not confuse the audience with (semi transparent) overlays such as channel branding. Present Watermark and Fingerprint as complementary.
