Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of right management method, Apparatus and system.
Background technology
At present, rights management is used very extensive, and the system that has the user to participate in will relate to rights management.Complicated along with what use, it is very complicated that rights management also becomes, if realize badly, will bring very bad user experience.
Generally, authority comprises function privilege and data permission.Wherein, function privilege is meant which operation the user can carry out, and for example increases, deletes, upgrades, inquires about.Data permission is that the scope to the operable resource of user limits, and for example user A can only check the data of Human Resource Department.
The scheme that realizes rights management in the prior art is as follows:
At first, according to form of catalogue resource, a catalogue can comprise a plurality of sub-directories, also can comprise a plurality of resources, and like this, the tissue of resource just becomes a tree structure, and the leaf node of this tree is a resource, and non-leaf node is a catalogue.
System is that (for example user A can upgrade certain catalogue to subscriber authorisation in unit with catalogue and resource, user B can delete certain resource or the like), simultaneously, can authorize also that (for example user A can upgrade the content of Shanghai area issue to one or more features of resource, user B can watch film of Liu Dehua protagonist or the like), in the grant item here, concrete operation be exactly function privilege (for example, upgrade, deletion, check), the scope of operation is exactly data permission (for example the issue area is the area, Shanghai, acts the leading role to be Liu Dehua).
And when subscription authentication, in relational database, inquire about as condition with data permission grant item (for example issuing area=Shanghai), judge whether the user has the right of operation, and then judge whether to carry out the operation of appointment according to the function privilege grant item.
In above-mentioned prior art scheme, the realization of Rights Management System as shown in Figure 1, this Rights Management System comprises authorization module, database and authentication module.Wherein, authorization module writes database with authorization rule, and authentication module is read authorization rule from database when authentication, then according to authorization rule query contents metadata in the database.
Its resource organizations's mode as shown in Figure 2, a catalogue can comprise a plurality of resources here, also can comprise a plurality of sub-directories.Obviously, this organizational form is the one-dimensional degree.
In realizing process of the present invention, the inventor is through discovering: more to same user's data control of authority, and authorized resource list structure complicated situation comparatively, during processes user data authority authentication, system need handle complicated query, very consuming time, so user experience is very poor.In addition,, when increasing a grant item, need to revise authorization module and authentication module, cause the system expandability bad because the organizational form level of abstraction of resource is not enough.
Summary of the invention
A kind of right management method, Apparatus and system, the authentication performance that can improve user data authority also can improve the extensibility of system.
Technical scheme is as follows:
A kind of embodiment of right management method comprises:
The authorized resource that meets one or more conditional expressions is set to a classification; At least the attribute that comprises content in the described conditional expression; A described classification comprises a plurality of contents, and a content is comprised by a plurality of classification;
Described classification as authorization object, and is set up full-text index to authorized resource.
A kind of embodiment of rights management device comprises:
Authorization module, the authorized resource that is used for meeting one or more conditional expressions is set to a classification, comprises the attribute of content in the described conditional expression at least; A described classification comprises a plurality of contents, and a content is comprised by a plurality of classification; Described classification as authorization object, and is set up full-text index to authorized resource.
A kind of embodiment of Rights Management System is characterized in that, comprising:
Authorization module, the authorized resource that is used for meeting one or more conditional expressions is set to a classification, comprises the attribute of content in the described conditional expression at least; A described classification comprises a plurality of contents, and a content is comprised by a plurality of classification; Described classification as authorization object, and is set up full-text index to authorized resource;
Database is used for the authorization rule that memory contents metadata and described authorization module write in advance, and described authorized resource is chosen from the content metadata of storage;
The full-text index storehouse is used to store the full-text index that described authorization module is set up;

Embodiment
The invention provides the embodiment of a kind of right management method, Apparatus and system, the authentication performance that can improve user data authority also can improve the extensibility of system.For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings, the present invention is described in more detail.
As shown in Figure 3, the process flow diagram for an embodiment of right management method comprises following process:
Further, present embodiment can also comprise:
When step 303, authentication, inquire about described full-text index, determine whether the user has operation permission.
Wherein, be by taxonomic organization's resource in the described step 301, promptly a resource can belong to a plurality of classification.Classification is a logical concept with hierarchical relationship, and the authorized resource that will meet one or more conditional expressions (promptly meeting one or more common features) can be classified as a classification.
For example, in the song management system, resource is exactly a song, and we can think a classification (as " Zhou Jielun song ") with the song that same singer sings, and also the song of same area distribution can be thought that a classification is (as " Hong Kong and Taiwan's music ", " Chinese music "), here, " Hong Kong and Taiwan's music " is exactly a subclassification of " Chinese music ", and, same song both belonged to " Hong Kong and Taiwan's music " probably, also belonged to " Zhou Jielun music ".
This just requires, and we will embody the characteristic of resource when adding resource, could regard some resource as a classification according to the general character that embodies on these characteristics like this.For example in the song management system, when adding a first song, must add the singer of song, as a classification just can be regarded the song that same singer sings in the distribution area of song, or the song of same area distribution is regarded a classification as.Can certainly be that some song is added a general character by the mode of upgrading, and and then regard these songs as a classification.
Need to prove that the characteristic of resource all is that the business development personnel are according to concrete business scenario definition.Certainly, following this situation might occur: two resources did not just have general character originally in real world, but we are for managerial convenience yet, for it adds a general character (as " path "), like this, " path " identical resource also can be regarded as a classification.
Opposite extreme situations is that a resource is exactly a classification, and at this moment, the notion of classification is consistent with resource, that is to say, always we can come organizational resources according to classification.And, in using mostly, also generally be to regard the resource that meets certain general character as an integral body to do control of authority.For example in Content Management System, certain content person of examining can only be examined the content of East China issue.
In the described step 302, when authorizing, its mandate to as if classification.Classification has hierarchical structure, can be inherited by subclassification in the classificatory grant item of father, unless subclassification is authorized again.
Because we always can come organizational resources according to classification, and satisfied the demand of rights management by taxonomic organization's resource, therefore, to classify as authorization object, how no matter rights management demand changes, and concerning rights management, just increases or reduced classification, can mainly not realize exerting an influence, just guarantee better expansibility yet it.
For example, in the music management system, begin to regard the music that same singer sings as a classification, and in this classification, do control of authority.Along with the development of business, need do control of authority to the distribution area of song, at this moment, only needing increases some classification according to the distribution area of song.Concerning Rights Management System, just increased some classification, it is mainly realized and need not revise.
In addition, in above-mentioned licensing process, write authorization rule in advance in database, so that use during subsequent authentication.
In described step 303, during authentication, obtain the authorization rule that writes when authorizing, when user's direct control resource, the tabulation of the described user-operable that inquiry obtains in advance according to user's authorization message, from described tabulation, obtain the conditional expression of each classification in the described tabulation of definition, and inquire about described full-text index as querying condition with described conditional expression, but obtain the Resources list of this user's executable operations, determine according to described the Resources list whether the user has operation permission.For example user A will revise certain resource, and right discriminating system at first obtains user A and can revise which classification so, and then judges whether this resource belongs to the revisable classification of user A.
Certainly, if certain classification of user's direct control, then can inquire about the tabulation of the described user-operable that the authorization message according to the user obtains in advance, directly the classification of user's operation and the project in the tabulation be compared, thereby determine whether the user has operation permission; For example, user A will give among the classification C and add resource, and right discriminating system will judge whether user A has the interpolation authority on the classification C so.
Need to prove that in addition after user's login, before the concrete operations, just can obtain the tabulation of this user-operable in advance according to authorized user message, for example user A can revise classification C, user J can check classification D etc.In the time of concrete data permission authentication, just need not go to obtain the tabulation of user-operable again, thereby improve the performance of system.
In addition, described authorized resource is to choose in the content metadata from be stored in database, that is to say that authorized resource may be the part in the content metadata, also may be the whole of content metadata.When the content metadata in the described database changes, need to upgrade synchronously the index information in the described full-text index.
The structure of an embodiment of rights management device 400 with reference to figure 4, comprising:
Described authorization module 410 also is used for writing in advance authorization rule to database.
Further, present embodiment can also comprise:
Wherein, described authentication module 420 further comprises: first query unit 421, second query unit 422, and determining unit 423; Wherein:
Described first query unit 421, be used for when user's direct control resource, the tabulation of the described user-operable that inquiry obtains in advance according to user's authorization message obtains the conditional expression of each classification in the described tabulation of definition from described tabulation;

Described second query unit 422 is used for inquiring about described full-text index with the conditional expression that described first query unit 421 obtains as querying condition, but obtains the Resources list of this user's executable operations;
Described determining unit 423 is used for determining according to the Resources list that described second query unit 422 obtains whether the user has operation permission.
In the foregoing description,, inquire about during for authentication by authorized resource being classified and setting up the full-text index storehouse.Like this, when authentication, adopt search engine that the full-text index storehouse of setting up is inquired about, can improve query performance greatly.
Below, by a concrete application example technical solution of the present invention is described further.
After the rights management subsystem adopts the present embodiment scheme in the Content Management System, as shown in Figure 4, wherein:
The authorized resource that authorization module 410 meets one or more conditional expressions is set to a classification, and with described classification as authorization object, and authorized resource set up full-text index, as above shown in the table 1; And responsible authorisation process, when authorizing, the concrete rules of competence are write database, for example user A can revise classification C.
Synchronization module (Synchronizer) is used for guaranteeing the consistance of full-text index storehouse and database, and just, the content metadata that assurance is authorized to is all set up index, and is placed on the file system.
Adopt above-mentioned rights management subsystem to realize that the process of rights management is as follows:
1, in Content Management System, will meet certain condition, for example the expression way of this condition is: the content of [certain relation on attributes symbol r value of content] is regarded a virtual classification as, and the relation character here comprises=,＜,,!=or the like, during mandate with these self-defining virtual classification as authorization object because a content can belong to a plurality of classification, so just realized the mandate of various dimensions.
Wherein, the organizational form of content as shown in Figure 5, a classification can comprise a plurality of contents, and a content can be comprised by a plurality of classification.
For example, set up a classification C, the definition expression formula of this classification is:
