Background technology
In order to detect the uncommitted digital multimedia video illegally propagated, digital watermark by universal research and is answered
With extensive.In Making Movies or film ejection stage, implantation can be taken to make one eye in film and can't see " pattern " information
Method.If these films are taken on the sly record by video camera, collection of illustrative plates of this insertion can be extracted and identify piracy
Source.
Some industry leaders are in order to identify and tracing pirate film, it is proposed that by the method for Coded Anti-Piracy (CAP),
I.e. toward increasing watermark in film.First Coded Anti-Piracy is designed by Kodak, subsequent Deluxe Laboratories couple
It is improved.Philips it is also proposed the mark for being named as a CineFence system in 2006.However, digital watermark is only
It is a kind of passive measure, he cannot eliminate and prevent shooting from taking on the sly.On the other hand, camera perturbation technique is intended to by seriously breaking
Bad film visual quality is taken on the sly to eliminate shooting, meanwhile, these interference signals is not interfered with the spectators of movie theatre.
Early stage, substantial amounts of camera interference method mainly make use of the principle of imaging sensor response infrared ray.Moved to disturb
Move video camera and light is generated in the picture of shooting, infrared emitter is mounted in the cinema.Except those transmitters
Etc. extra cost and regular job expense, this scheme can be by enclosing appropriate filter on camera lens.It is but this
Mode is easy to be avoided because of the selection of the person of taking on the sly.
