Description
Technical field
The embodiment of the present invention relates to copyright protection field, is specifically related to a kind of copy-right protection method and system.
Background technology
Along with the develop rapidly of the Internet, the piracy of film and video content and reproduction problem are increasingly serious, this grievous injury film and video content creator and publisher's interests, upset the order of film and video content industry.
The protection of existing video content mainly contains following three kinds of methods:
One, utilize copyright protecting system protection: protect by copyright protecting system; first the system combination that need to carry out series of complex to video content in service end is encrypted; then video content encryption key pair is provided; video content is encrypted and is watched by end user by encryption key pair; this needs the support of delivery platform and user terminal; not only user uses loaded down with trivial detailsly, and content safety hidden danger is larger.Existing copyright protecting system cannot meet and prevent day by day serious piracy and impinge issue;
Two, identification marking or label: by the mode of direct identification marking in terms of content or label, can effectively prevent piracy, but video content, owing to having added other information to affect its pure, can affect paying customer's perception, and cannot stop bootlegger directly to make video recording;
Three, eletric watermark: eletric watermark is a kind of technology that loads invisible digital watermark information on digital media content, can calculate the contained information of watermark through evidence obtaining and calculation, therefore finds rapidly the evidence in pirate source.Its advantage is that watermark is invisible, can't affect watching of normal users, and can extract key message evidence obtaining by the data of testifying.Its shortcoming is passive type, can only play and review effect afterwards, the pirate method that can not effectively stop bootlegger directly to make video recording from display screen.
Existing video content can not well be protected, therefore in the urgent need to a kind of method that can protect well video content.
