Claim One:
1. A system and apparatus for evaluating the reliability of a watermarking technique for a video sequence, said system and apparatus comprising: a) a calibrating means adapted to calibrate said system and apparatus using a test original video sequence and a test attacked video sequence in compliance with predetermined degrees of quality; b) an attacking means adapted to attack embedded watermark in said video sequence, said attack selected from a group of attacks; and c) an evaluating means including a comparator means for comparing the test original video sequence with test attacked video sequence and the watermark in the test attacked video sequence to evaluate the reliability of a watermarking technique to give a reliability score wherein said calibrating means is adapted to: compare two identical frames and calibrate said apparatus to treat such identical frames as best case data sets: compare two completely different frames and calibrate said apparatus to treat such completely different frames as worst case data sets; and compare and a compressed-decompressed frame and calibrate said apparatus to treat such compressed-decompressed frames as average case data sets.
