Description
Technical field
The present invention is a kind of solution of net environment protection digital audio/video works copyright, refers more particularly to the digital publishing rights transfer problem in the DRM model under the peer to peer environment, belongs to multimedia digital copyright protection field.
Background technology
Digital copyright management (Digital Rights Management, be called for short DRM) refers to the technical tool of digitized content intellectual property protection and management in production, propagation, sale and use procedure.Its concrete application can comprise the protection of the digital product contents such as ebook, video, audio frequency, e-book.It is by in digital space, and authenticated is spuriously authorized user's interest field, standard user's behavior is come the owner and the operator's of Support Digitalization information right and interests.The target of DRM is that the containment of application technology means is pirate; the intellecture property of protection digitized content; guarantee the unimpeded of digital product market sale channel; ensure author, publisher, the interests of retail trader and user's legal right to use; thereby try to achieve realization and the balance of benefits of different parties, promote the prosperity of electronic publishing industry.
Digital signature refers in the asymmetric-key encryption system, by using the hashed value of the regular length of data formation that hash function will send the user, with self private key hashed value is encrypted afterwards and operates formed ciphertext and namely be called the user to the data signature of hashed value corresponding data.PKI by the user carries out digital signature authentication to information and can guarantee the user to non repudiation and the information integrity of transmission information, is a kind of important technical that solves communications field controversial issue.The digital one time signature technology is an emerging branch of digital signature field, its implication refers to that the every operation of this signature scheme once all will regenerate a pair of signature key, comprise public signature key and private key, and this signature key is only to message safety is effective first, but can to signed this then message can carry out unlimited checking repeatedly.Popular says, be that the right generation of the signature key of digital one time signature is relevant with the content of the message that will sign, thereby therefore a pair of PKI can only effectively effectively be verified for this message, changes other message into and then can not effectively sign and verify, therefore be called disposable signature verification.Produced again on this basis disposable allograph algorithm, it is the disposable signature algorithm that has increased agent functionality on original basis, so-called agent functionality is that original user can be the disposable proxy signature key of the generation of designated user, the user can use this key that media content is carried out the once signed operation, and this signature can be tested by the key of original user, just as the signature that my key of being acted on behalf of is done, be thus disposable proxy signature key.The transfer of realizing copyright in DRM that is produced as of disposable proxy signature key provides the effective theory foundation.
Current DRM system generally adopts the method that media file is encrypted, and the user namely can be decrypted broadcast to media file after the broadcast authority that obtains file.But along with the development in multimedia market and the variation of user's request, people wish the entitlement of digital product is transferred the possession of.For example, user has obtained the right of broadcasting to multimedia file, but after appreciating media content, namely lost feeling of freshness, while has produced demand to other contents of media files again, therefore if can transfer the possession of and the income that obtains can be used for obtaining other was not appreciated the right to use of media the copyright of existing media, then not only save spending, and increased practicality and the dirigibility of DRM system.A solution that the present invention produces for separating this demand just.
Summary of the invention
Technical matters: the technical issues that need to address of the present invention are that a kind of numeral of supporting copyright transfer is provided
The copyright implementation model by introducing the one time key encryption mechanism, solves the media copyright transfer problem under the peer to peer environment, is mainly used in the DRM system media file owner to the transfer operation of media copyright.
Technical scheme:Method of the present invention is a kind of method of tactic, by introducing the one time key encryption mechanism, solves the media copyright transfer problem under the peer to peer environment, specifically realizes by following scheme:
One, architecture
The realization of this programme mainly is divided into two parts and uses: node client application and node server end are used.The DRM copyright trading that the node client application refers to have a mind to transfer the possession of self media copyright user and has a mind to buy the node of copyright is used, and can be used as in the middle of the DRM protection system of a Module-embedding client node.The node server end is used and to be referred in the P2P network super node arranged by the stronger node of processing power or stream media rights management person, super node forms the P2P network each other, be responsible for the copyright trading process of node in certain zone, the normal operation of service end node applications needs being used in conjunction with of node copyright information database, and the below is specifically described as follows the application of each part:
Transfer the possession of the DRM copyright trading module of copyright node: be responsible for to the authentication of copyright trading server end node affirmation to the property in copyright of digital media content.
Buy the DRM copyright trading module of copyright node: be responsible for sending the copyright trading request to node, carry out the reception of transaction payment and property in copyright.
Copyright trading node server end copyright trading module: the request of being responsible for copyright authentication is processed, and after the copyright transfer transaction is finished the copyright trading database information is upgraded operation.
Two, method flow
The groundwork flow process of system is as follows:
Step 1: the original owner of media file is at first to the own entitlement to media file of copyright transfer server end node registration, the descriptor that should comprise the media file of registering in the login request message that sends, node identification, and node is to document of title's information of this media file, wherein node is to obtain after the cryptographic hash of media file textual content and node identification information is signed with original owner's private key to document of title's file of media file, adopt the PKI of server end node to be encrypted entitlement information afterwards, send to the server end node, the server end node is verified user's signature after receiving registration information, and definite nodal information and media description information consistent with information in the entitlement signature after, all information are put into media copyright information database;
Step 2: request copyright node sends the copyright transfer request message that comprises required media file to server node, if exist the user to ask the information of media file in the server node inquiry copyright information database, then service node return comprise the possessory node address chained list of the media of asking, requesting node and the media file owner carry out the negotiation of copyright transfer aspect;
Step 3: pass through if consult, then media file request person sends to copyright owner's node with this nodal information, copyright owner's node at first carries out proprietorial authentication to server node afterwards, if authentication goes on foot by then continuing the 4th, otherwise copyright trading is ended;
Step 4: the media file owner node moves disposable proxy signature key algorithm, generates the copyright voucher of media file for buying the copyright user, sends to afterwards server node;
Step 5: after purchase copyright node carried out the copyright payment by third party's payment platform, server node sent to the purchase node with media copyright credentials file;
Step 6: buy node and need to arrive server node authentication copyright credentials file when playing media file for the first time, whole copyright trading process finishes.
Beneficial effect:The inventive method has proposed multi-medium data copyright transfer scheme, is mainly used in the media file owner in the DRM system to the transfer operation of media copyright.Below we provide specific description.
1. security
Because the possessory information of media file is kept at the server node end, only have the original owner of media file just to have the right to carry out the transfer operation of media copyright.Although other node has the media credentials file by purchase; and can be by the authentication of server node; but because the identification information of buying node being arranged in the licence, therefore can't again transfer the possession of copyright, thereby effectively protect the original possessory interests of media file.
2. dirigibility
Because native system adopts disposable allograph algorithm, therefore the media file owner not only can provide the copyright voucher to the user of self subordinate server node, and can be by providing disposable proxy signature key to other server node, allow the own granting of other server node agency copyright voucher, both alleviated the flexible Application that self burden has improved system simultaneously.
3. economy
Because the original owner of media file only has one, so the original user transfer can only be the copyright of media file rather than the entitlement of file.The copyright of so-called media file is namely to the download of media file, the right of appreciation, and do not comprise the right of utilizing this media file further to make a profit.Simultaneously, because therefore the right that copyright is only used to the user so that the less cost of purchase user effort can obtain, has also enlarged the promoted extension of using simultaneously, thereby has improved economic benefit.

Embodiment
For convenience of description, our supposition has following digital publishing rights to transfer the possession of the system applies example:
Suppose that user Alice wishes to obtain by native system the broadcast copyright of multimedia video frequency file, Bob is the original owner of media file, and embodiment is as follows:
The Key Acquisition Module that step 1:Alice at first moves DRM obtains a pair of RSA unsymmetrical key pair, to the entitlement information of server node registration oneself, comprise node identification PID, media file descriptor and own document of title's file to media file in the registration request afterwards.Wherein node is to obtain after the cryptographic hash of media file textual content and node identification information is signed with source document owner private key to document of title's file of media file, adopt the PKI of server end node to be encrypted entitlement information afterwards, send to the server end node with registration information, the server end node is verified user's signature after receiving registration information, and whether definite nodal information and media description information be consistent with the corresponding informance in the entitlement signature, if consistent, all information are put into media copyright information database.
Step 2: request copyright node sends the copyright transfer request message that comprises required media file to server node, if exist the user to ask the information of media file in the server node inquiry copyright information database, then service node return comprise the possessory node address chained list of the media of asking, requesting node can carry out with the media file owner negotiation of copyright transfer aspect.
Step 3: consult to obtain request by rear Alice node and buy node identification information PID, generate corresponding HASH value in conjunction with media content information and Bob node PID.Move afterwards disposable proxy signature key algorithm and obtain One-time proxy signature key pair, to HASH value is signed, generation document of title operates, and sends it to server node with disposable proxy signature key.
Step 4: notice Bob node carried out delivery operation after server node was received voucher, and Bob pays property in copyright by third party's payment platform.
Step 5: server node sends to the Bob node with media file copyright voucher after receiving the advice of payment.
Step 6: obtaining the copyright node needs to server node copyright to be authenticated before playing media file for the first time, if nodal information then authentication consistent with the nodal information in the copyright voucher passed through, otherwise node is piped off, its copyright permissions that cancels, process of exchange finishes.
