Abstract
The invention discloses a multimedia copyright protection method based on a security engine, which realizes the encryption and decryption technology of multimedia files by introducing the security engine, realizes file encryption, secret key distribution and electronic signature of digital watermarks on the files, and then carries out authorization management on the files through an authorization management module, distributes corresponding authority to purchasing users, and realizes the unified packaging protection of multimedia copyright by various encryption technologies. By the method, the multimedia file is safely processed at the multimedia service provider end, such as content encryption, digital signature, user authority configuration and the like, the obtained multimedia file is decrypted, signed and verified at the user terminal, the authority is realized, and the file playing function is realized, so that unified and standard data safety service is provided for the multimedia service provider.
Description
Technical field
The present invention relates to data encrypting and deciphering technical field, be specifically related to a kind of multimedia copyright protection method based on security engine.
Background technology
Along with the universal of network and the development of computer technology, the media products such as digital picture, audio frequency, video bring great facility.But because digital multimedia easily copies, unauthorized copy the legitimate rights and interests compromising copyright owner with illegal distribution original works, therefore digital multimedia is in the urgent need to copyright protection.
Multimedia copyright protection mainly contains follows the tracks of two large class technology based on cryptographic digital copyright management with based on the copyright of digital watermarking.
Digital copyright protecting (DRM) is the Main Means at present multimedia digital content in network being carried out to copyright protection.To content of multimedia from generation to distribution, carry out identifying, conclude the business, protect, monitor and following the tracks of from the whole process being sold to use, the copyright protection to multimedia making business, publisher's media product is provided.At present, unification of three nets, novel from media, micro-letter social platform etc., new copyright protection demand is proposed to digital publishing rights.
Summary of the invention
The technical problem to be solved in the present invention is: in order to provide effective data security service to multimedia service provider, the invention provides a kind of multimedia copyright protection method based on security engine.
The technical solution adopted in the present invention is:
A kind of multimedia copyright protection method based on security engine; described method is by introducing the encryption and decryption technology of security engine realization to multimedia file; realize file encryption, key is allotted, digital watermarking signs electronically to file; by entitlement management module, empowerment management is carried out to file again; distribute corresponding authority to purchase user, realize multiple encryption technology uniform packing protection multimedia copyright.
It is as follows that described method comprises process:
After multimedia file is supplied to multimedia service supplier by multimedia file producing business; supplier passes through security engine functional module to multimedia file expressly in server end management software; utilize in security engine the multiple encryption algorithms that provides to file be encrypted packing, secret generating, digital signature, etc. multiple encryption method; supplier can therefrom select combination in any to use, and is packaged into a multiple cryptograph files being encrypted in one of collection to file;
For the buying service condition of different user, by the business information of user, as comprised user ID, content identification, key information and authority information, client public key certificate and user's signature information etc., being packaged into license authorizes file, being finally issued to the client of each user;
Also security engine functional module is added in the terminal software that terminal user uses, when user uses multimedia file time, the multimedia file of encryption enters security engine functional module, is decrypted process of unpacking, as file decryption, key authentication, digital signature authentication etc. to the file of encryption; Then according to the license authorizes file provided from service provider, the use authority that terminal user carries out multimedia file is resolved, comprise user ID, content identification, key information and authority information, client public key certificate and user's signature information etc., finally in terminal software, multimedia file is played back.
The enciphering and deciphering algorithm that described security engine provides comprises: secret generating, AES enciphering and deciphering algorithm, digital content signature and sign test algorithm, synopsis algorithm, ticket signature algorithm etc.
The content of described encryption packing comprises: the data encryption key adopting symmetrical aes algorithm and 128, is encrypted protection to content of multimedia; Meanwhile, the summary of Computed-torque control, carries out digital signature to content, the completeness and efficiency of checking digital content; According to business demand, single or multiple content of multimedia and business information are packaged into product, are sold to terminal user.
Described key, according to public-key cryptosystem, uses aes algorithm to generate, adopts classification and demixing technology to key storage, distribute, according to the user demand of key, to key updating and destruction according to CIPHERING REQUEST to key.
Described empowerment management, refers to the business information of user, as comprised user ID, content identification, key information and authority information, client public key certificate and user's signature information etc., being packaged into license authorizes XML file, being handed down to client.
Beneficial effect of the present invention is:
Pass through the inventive method, at multimedia service provider end, safe handling is realized to multimedia file, as content-encrypt, digital signature, user right configuration etc., user terminal to obtain multimedia file be decrypted, signature check, authority realize, and the playing function of file, for multimedia service provider provides data security service that is unified, standard.
