Description
Technical field
The present invention relates to digital copyright management (DigitalRightManagement is called for short DRM), particularly relate to a kind of system for numeral copyright management and method.
Background technology
Along with the fast development of Internet and digitizing technique, the digital contents such as the e-book of online transaction and propagation, electronic newspaper, music, film, picture, game and software get more and more.But, because digital content is easy to be replicated, revise and propagate, there is a large amount of piracies and impinge issue in the digital content of online propagation, and, existing digital content secondary distribution copyright management mechanism, lack effective tracing detection mechanism, make the proprietorial branch problem of digital content, become a large difficulties of digital copyright management.
Copyright is by piracy and spreading unchecked of abusing, not only bring larger economic loss to copyright owner, the simultaneously also grievous injury creative enthusiasm of copyright owner, reduces working enthusiasm and the confidence of digital publishing industry, all brings huge harm to whole industry.Set up complete set, practical and effective digital copyright protecting mechanism, become already whole industry healthy development necessary guarantee and in the urgent need to.
Digital copyright management in prior art (DigitalRightManagement is called for short DRM) technology is widely used.Digital copyright management refers to that copyright side is used for the correlation technique of control figure content usage authority, and by these technology, publisher can guarantee the corresponding required deed restriction of digital content.
Modal DRM technology has digital watermarking, digital encryption and digital certificate etc.
Some identification informations (i.e. digital watermarking) are mainly directly embedded into carrier central (comprising multimedia, document, software etc.) or the secondary indication (structure of amendment specific region) of digital content by digital watermark technology, and do not affect the use value of original vector, be also not easy to be found out and again revise.Normally, digital watermarking can run through whole digital content, the information etc. of information, publisher's information, the even original purchase/user of distribution channel information belonging to mark copyright.These watermarks can retain in the process of circulation of digital content always, as illegally utilized, can show very lucidly.But digital watermark technology is only applied to the use of warning and tracking, can not substantially stop the situation that publication content is copied illegally propagation, and digital watermark technology also can destroy the reading experience of user from source.
In existing digital-scrambling techniques, simple cipher mode is often taked in the encryption of content, and as only used simple symmetric cryptography to be encrypted content, security can not get good guarantee.For utilizing public key encryption file content itself, the encryption method of private key declassified document also has obvious defect, such as when the key of deciphering is when sending to user, once be obtained key by hacker, then hacker etc. can declassified document easily, and therefore this method can not guarantee the actual copyright interest of the copyright side of digital content veritably.Meanwhile, digital-scrambling techniques can only solve the right problem of reading, can not solve the attaching problem of copyright, also cannot realize the management of the state to copyright, timeliness and circulation etc.
Digital certificate technique, mainly adopts digital license user identity and equipment to be carried out to the mode of certification, legal user generally can be allowed on legal equipment to use shielded copyright.But along with the fast development of mobile Internet, the variation of mobile terminal device, the online network condition required for the checking of digital certificate cannot ensure the use of user under off-line state.And the mode of digital certificate and apparatus bound mandate makes user be difficult to digital certificate to transfer on other equipment use, and reduces Consumer's Experience.
