The spectator can keep the card as souvenir, and from this point on, EVERYTHING is fully examinable!

观众可以使卡作为纪念品，并从这个角度上，一切全考试！

If couples of users make a coalition and collude to generate a new image or video section, they would weaken the examinable energy of the fingerprint a lot, hence avoid being traced.

如果若干用户联合来进行共谋,伪造一份新的视频作品,就会大大削弱可检测出的指纹的能量,从而躲过检测者的追踪。
