Abstract:
Signature robustness is the most important criteria that must verify a watermarking approach. However, existing
watermarking evaluation protocols always tested simple attacks like rotation, cropping, and compression
but did not consider many dangerous attacks such as camcording which is more and more used for videos. In
this paper, a new robustness evaluation approach for video watermarking is proposed. It is based on on-line attack’s
game using crowdsourcing technique. In fact, the proposed game is provided to different users who will
try to destruct an embedded signature by applying one or many combined attacks on a given marked video.
Switch the choice of the users, the most important attacks can be selected. In more, users must not destroy
the visual quality of the marked video to evaluate the tested watermarking approach. Experimental results
show that the proposed approach permits to evaluate efficiently the robustness of any video watermarking. In
addition, obtained results ve
rify that camcording attack is very important in video watermarking evaluation
process.
