4. this digital right management system has the function of the real-time management of user's cost of use, report.
Introduce the present invention below and carry out the operating process of digital copyright management and the realization of expenses management report.
Introduce the practical operation flow process of digital copyright management at first in detail.The present invention can be divided into two kinds of online management and non-online managements for the copyright management of digital resource, and the user can also can use by unit by online use digital resource.
Fig. 4 A is the overview flow chart of user's unit use digital resource, and its steps in sequence is:
1. User login user terminal system is by network access server and the corresponding service condition of the digital resource that provides is provided.
2. after the user makes and wishes that unit uses the decision of certain digital resource, send request to server by the user side digital right management system.
3. server end digital right management system process user application then generates the user license document if check and approve.
4. digital resource and user license document packaging ciphering.
5. the encrypted packet that will comprise digital resource and user license document by network is sent to user side.
6. the user side digital right management system is deciphered encrypted packet, and providing to the user can be for the digital resource of unit use.
When Fig. 4 B used digital resource for the user applies unit, server provided the detailed process of digital resource and issue licenses to the user.Step 1, the user logs on server by the local digital right management system, and a certain use right of certain digital resource and constraint accordingly and obligation are bought in application; Step 2, after license creation administration module 101 receives that user's unit uses request, inquire about this user account to User Information Database, whether enough pay this cost of use and user credit record etc. as remaining sum among the account, if this user then requires the user by the network defrayment of going ahead of the rest for use first, after the user satisfies service condition, license creation administration module 101 generates the unit user license document for this digital resource, and back-up storage is advanced in this customer documentation in the User Information Database; Step 3, license creation administration module 101 are changed the syntax that the user license document carries out between AVS-DREL standard and the MPEG21-REL standard according to user's actual use standard, after the conversion user license document are sent to packaging ciphering module 220; Step 4, the resource that license creation administration module 101 notice resource management modules 210 user applies are used; Step 5, resource management module 210 are extracted this resource and are encapsulated, encrypt, register from resource database 400; Step 6, packaging ciphering module 220 is packed the resource of receiving with corresponding user license document, the right of demarcating this digital resource, and encryption is beneficial to management and transmission; Step 7 is to the digital resource and the user license document of user's permission to use and transmission packing.
Fig. 4 C receives the process of the unit use resource behind packing digital resource and the user license document for the user.Step 1, deciphering parse module 230 is decrypted and unpacks; Step 2 is sent to licence parsing module 102 through the user license document that unpacks, and shows the pairing original user licence of this resource right document by resolving the user license document.The user license document of this parsing afterwards is sent to licence modular converter 103, is converted to the Digital Media standard that the user uses instantly, and the user can check transformation result; And can check the code of the pairing expansion of this conversion XML of identifiable language.At last, license validation module 104 will be carried out the verification of correctness of syntax and semantics at this user license document, obtain user's rights of using information; Step 3 is stored in the user side database 500 simultaneously through the user license document of checking and the resource of having deciphered; Step 4 when the user need use this resource, is carried out information interaction by use and management module 240 and user side database 500, limits according to the right in the user license document and extracts resource; Step 5, use and management module 240 is to user's playing resource.Cross after date in the usage license, the user license document can be notified this resource in the use and management module 240 deletion user side databases.
The online use digital resource of user uses with unit and compares, maximum difference is, unit is the disposable complete user license document of issuing for resource when using, and resource all is sent to user side, and the user can use the resource that is stored in the user side database at any time; And during online use digital resource, resource is that the form with data stream constantly is transferred to user side, and corresponding therewith, each packet all can have corresponding user license document, temporary this digital resource stream of user side database, and play to the user synchronously.
Fig. 5 A is the flow process of the online use digital resource of user, and its steps in sequence is:
1. User login user terminal system, by network access server and the corresponding service condition of the resource that provides is provided, the selected resource that needs online use of user proposes the rights of using application to server numeral right management system.
2. server end digital right management system process user application then generates online user license document if check and approve.
3. the user license document is be delivered to user side.
4. when obtaining the online use of the user of online user's licence document, upload the user license document to the server end system for numeral copyright management.
5. after the server end digital right management system is examined the user license document, resource is divided into several little packets, each packet and corresponding user license document packing transmit first and wrap user side, and the user side digital right management system is handled the back and play.
6. the server end digital right management system sends next packet, transmits up to packet to finish.
When Fig. 5 B was the online use resource of user, the flow process of user license document was issued in server end digital right management system response user's application.Step 1, the user logs on server by the local digital right management system, and a certain use right of certain resource and constraint accordingly and obligation are bought in application; Step 2, after license creation administration module 101 is received the online use request of user, to User Information Database 300 these user accounts of inquiry, whether enough pay this cost of use and user credit record etc. as remaining sum among the account, if this user then requires the user by the network defrayment of going ahead of the rest for use first, after the user satisfies service condition, license creation administration module 101 generates the online user's licence document for this resource, and back-up storage is advanced in this customer documentation in the User Information Database; Step 3, license creation administration module 101 is according to user's actual use standard, the syntax that the user license document carries out between AVS-DREL standard and the MPEG21-REL standard are changed, after the conversion user license document is sent to packaging ciphering module 220, the packaging ciphering that carries out the user license document is so that transmission; Step 4 transmits the user license document to the user.The user unpacks deciphering after receiving this user license document, by resolving, obtain online use right after the conversion, checking, and with the user license document storage in the user side database.
Fig. 5 C is the process of user based on the online use digital resource of user license document.Step 1 when the user needs this resource of online use, is uploaded the user license document of applying for by the local digital right management system.Step 2, license creation administration module are resolved, change, are verified after receiving and uploading the user license document.License creation administration module 101 reads this user license document record and is sent to licence parsing module 102 from User Information Database, module 102 will be according to the online request for utilization of user at this resource submission, search and resolve the pairing user license document of user applies, the temporary permit request and the original subscriber's licence document that generate are compared, whether the inspection user application satisfies this user license document constrained, and the checking result returns demonstration.Module 101 is delivered to licence modular converter 103 with the user license document of being created simultaneously and is carried out the XLT standard handovers, the user license document that will meet the AVS-DREL standard specification definition converts the user license document that meets the MPEG21-REL standard specification definition to, the content meaning is constant, and deposit in the User Information Database corresponding document folder, the record transformation result, and return demonstration.At last, the user license document that module 101 will be resolved after the conversion is delivered to license validation module 104, carries out the standard criterion checking, and record checking result also returns demonstration (by checking or miscue); Step 3, after the user license document meets the requirements, the license creation administration module 101 approval users use, and the licence that generates first resource packet sends to packaging ciphering module 220, and back-up storage is in this user's corresponding account of User Information Database 300; Step 4, the online use resource that license creation administration module 101 notice resource use and management module 201 is chosen; Step 5, resource use and management module is extracted resource from resource database 400, resource is divided into several little packets in order, each bag is encapsulated, encrypts, registers, and first bag is sent to packaging ciphering module 220; Step 6, packaging ciphering module 220 demarcate the right of this resource, and packaging ciphering are beneficial to management and transmission with the resource packet and corresponding user license document packing received; Step 7 transmits packing resource and user license document to the user; Step 8, deciphering parse module 230 is decrypted and unpacks, the user license document is delivered to license management module 100 to be resolved, change, verifies, finished by module 102,103,104 respectively, the user side digital right management system carried out when step was used with unit parsing, conversion, checking are identical; Step 9, user license document through checking is kept in user side database 500 simultaneously with the resource packet of having deciphered, and play to the user by use and management module 240, the use and management module is in the use request that proposes next packet to server DRM, and so circulation all transmits until all resource packet and finishes.After treating that online resource plays, online user's licence document lost efficacy, and use and management module 240 will be deleted this temporary in user side database resource.
Fig. 6 A is the licence component structural representation of apparatus of the present invention system.Licence is the core that the present invention realizes copyright management, is made up of main body, right, resource, constraint and voluntary element.Realize the functional module of the concrete operations of licence, comprise license creation administration module 101, licence parsing module 102, licence modular converter 103, license validation module 104, its concrete function is introduced in front in detail.
When the definition digital right, main body has defined the role under the varying environment, can be expressed as concrete people, tissue, machinery and equipment, application program, the network terminal or certain class role etc.Main body is a kind of enforceable object elements, also is abstract types of elements, and main element itself is not represented any concrete entity, and the element of type of subject occurs once in licence units at least.The present invention looks demand in the audio standard according to AVS, and at being worth the residing diverse location of main body in the transfer chain, main body is divided into right issuer and right winner.When having a certain right of the common enforcement of a plurality of main bodys, can define this main body set by the main body group.
In the description for digital right, a kind of action that is allowed to of right representative makes main body under the authorization identifying environment, is authorized to the operation to certain resource enforcement, semantically is being associated with certain resource sometimes.Right is a kind of enforceable object elements, also is abstract types of elements, and right element itself is not represented any concrete operation, and the element of type of right only occurs once in licence units.The present invention looks demand in the audio standard according to AVS, and at different main bodys and different environments for use, roughly can be divided into common right and senior right to right.
Main body is the video of vest right thereon, digital resources such as audio frequency.Can be a copyright (e-book, audio frequency, video or image etc.), can be service (as mail service etc.), also can be the information that has of certain entity (as someone e-mail address etc.).Other standard is more quoted in the description of resource part, as: the description of education resource can be quoted learning object metadata (Learing Object Metadata).Resource is a kind of enforceable object elements, also is abstract types of elements, and resource element itself is not represented any concrete entity, and the element of resource type occurs once in licence units at least.The present invention looks demand in the audio standard according to AVS, and multi-form at resource is divided into resource types such as looking audio frequency to resource.When having multiple related resource in the licence units, can define this related resource set by the resource group.
Constraint is to define the condition that should satisfy when main body is used respective right to resource, it is a kind of enforceable object elements, be abstract types of elements, constraint element itself is not represented any concrete entity yet, and the element of constrained type occurs once in licence units at least.The present invention looks demand in the audio standard according to AVS, and the different range at constraint can be divided into constraint constrained types such as space, time.When having multiple constraint in the licence units, the relation of a plurality of about interfasciculars is defined by the logical relation in the base attribute.
The voluntary element of the present invention's original creation is certain responsibility that main body is born when exercising certain right.For example main body is used resource, just necessary post-pay paystation, the obligation of main body that Here it is.In " obligation ", just can define the modes of payments, for example, free, use before, use back, exchange etc.The present invention solves the expense real-time management of digital copyright management and reports this technical matters, realizes by the device that expenses management is set in the obligation item.In the obligation item, also may be required in and add descriptive information such as copyright notice and copyright operation instruction in the resource, so that the recipient of resource understands the situation that resource is used.Obligation is a kind of non-imposed object elements, also is abstract types of elements, and voluntary element itself is not represented any concrete entity, and the element of voluntary type can not occur in licence units.The present invention looks demand in the audio standard according to AVS, at the different content of obligation, can be divided into way of paying to obligation, voluntary forms such as interactivity requirement.When having multiple obligation in the licence units, the relation of a plurality of about interfasciculars is defined by the logical relation in the base attribute.Realized the value-added functionality of voluntary expenses management simultaneously.
Digital copyright management of the present invention adopts expansion identifiable language (XML) to describe the user license document, and it is carried out resource management and transmission; The present invention uses the exemplary mechanism (being schema mechanism) in the expansion identifiable language to carry out the definition of licence standard, this regulation and stipulation the syntax and semantics rule that should follow of user license document xml code, in application, follow this standard and carry out the generation of licence document, read and operation such as modification.In apparatus of the present invention, the sequence of operations of being done for the user license document will be followed this digital right descriptive language (Digital RightExplanation Language, DREL) the defined licence standard of standard and carrying out.
The licence normalized definition right expression language standard part and the rights data dictionary part of licence document.The right expression language has partly defined the basic structure of this standard, Function-expandable architecture and expandable structure.The rights data dictionary is at the element in the licence, and data elements such as attribute define and standard, and data dictionary is expressed with the mode of vocabulary, is a value tabulation of recommending to use.Fig. 6 B is exactly expansion identifiable language (XML) the code synoptic diagram of a user license document.
The present invention realizes the real-time management report of expense in to digital copyright management.And the real-time management of expense report is what to finish jointly by the voluntary element in digital right management system and the licence.
Fig. 7 is licence (relating to an expenses management) component structural representation.In the obligation item of licence, apparatus of the present invention are provided with two entries, expense form and use track.The expense form is that cost of use standard and the user of this licence binding resource units time of record is the expense of this resource pre-paid; The service time of using track then to write down this binding resource.By cost of use standard and the service time of unit interval, digital right management system just can calculate the expense situation that the user uses.
The flow process that Fig. 8 uses for the subscriber's local enquiry fee.Its core texture is expense computing unit and the expense form in the licence in the use and management module 240 and uses the entry of track.The idiographic flow of subscriber's local inquiry is, step 1, and the user proposes the inquiry into expenses requirement of a certain resource by the local digital right management system; Step 2 after use and management module 240 is received the inquiry into expenses application, is extracted expense form in this resource binding licence and use track record in the user side resource database 500; Step 3, use and management module 240 reception fees are with form and use track record, deliver to the expense computing module; Step 4, the expense computing module is with this resource units time cost of use and multiply each other service time, draws the expense of having used, draws user balance according to user's pre-paid expense again; Step 5, use and management module 240 be to user's mail sending charge per message operation report, comprises this resource units time cost of use, service time, cost of use, remaining sum.
If need the cost of use of all resources of inquiring user, use and management module 240 can be extracted the expense form and use track in all stored in user side database user license documents, calculates respectively and gathers the overall operation report that mail sending charge per message is used again.
Fig. 9 is service provider's inquiring user cost of use flow process.Compare with the flow process that the subscriber's local enquiry fee is used, so difference is only proposing the inquiry into expenses request by the license creation administration module 101 among the server end DRM to the use and management module 240 of user side DRM, and report on expenses also is to be sent to server end license creation administration module 101 by network.License creation administration module 101 is stored in report in this user's of user's confidence database the account after receiving report on expenses, as the ingredient of user credit record, for providing reference frame to this user's issue licenses from now on.
Computation process user for expense is sightless, carries out on the backstage fully, has guaranteed the reliability of computation process, avoids user's individual to use information leakage simultaneously.
Figure 10 is the XML structural drawing of relevant expenses management in the licence.The key that realizes real-time expenses management is a licence, and licence also is the key that realizes digital copyright management and power descriptive language simultaneously.The design's licence content is noted down by the XML form, and meets corresponding XML Schema standard.
Licence is made up of essential main body, resource, right, constraint and optionally voluntary five elements, and Figure 10 has ignored the inner structure of preceding four elements, and has described the composition of voluntary element emphatically.At the different content of obligation, can be divided into way of paying to obligation, voluntary forms such as interactivity requirement.Wherein when obligation adopted the form of way of paying, system realized the real-time management to expense by generation, transmission and parsing to licence.
