<First Embodiment>
(Configuration of access right information management device)
FIG. 1 is a schematic diagram showing a configuration of an access right information management apparatus 10 according to the first embodiment of the present invention.

  The access right information management apparatus 10 includes a primitive service access right information storage unit 11, a primitive service access right information management unit 12, a composite service definition information storage unit 13, a composite service definition information management unit 14, and a composite service access right information management unit 15. A composite service access right information calculation unit 16 and a composite service access right information storage unit 17 are provided. In the following description, “primitive service” refers to a service of minimum granularity that is a material of a composite service.

  The primitive service access right information storage unit 11 is a storage device that stores access right information for a plurality of primitive services. As shown in FIG. 2, the primitive service access right information storage unit 11 stores a service name and “primitive service access right information” for each service number. The data structure when actually storing in the storage device is as shown in FIG.

  The primitive service access right information management unit 12 accesses the primitive service access right information storage unit 11 and manages access right information of a primitive service that is a material. When the primitive service is added or deleted, the primitive service access right information management unit 12 adds or deletes the access right information of the primitive service stored in the primitive service access right information storage unit 11. The primitive service access right information management unit 12 also manages changes in access right information for primitive services.

  The composite service definition information storage unit 13 is a storage device that stores “composite service definition information”. The composite service definition information is information indicating what kind of primitive service the composite service is configured as shown in the concept of FIG. 4, for example. The combination of each primitive service includes “order information” and “branch condition information”. Are associated with each other. That is, in the composite service, the usage relationship of the primitive service is defined in the form of a directed graph. Note that once the composite service X is defined, the composite service X can be handled in the same way as a primitive service, and a new composite service Y can be defined in combination with other primitive services. In short, composite services can be defined in a nested state.

  In the example of FIG. 4, the composite service A includes primitive service 1, composite service 2, primitive service 4, composite service 5, primitive service 1, primitive service 3, primitive service 4, composite service 5. It consists of a primitive service 6, a composite service 7, a primitive service 8, and a composite service 9. An example of the data format when the composite services A and B are stored in the storage device is represented as shown in FIGS. 5A and 5B, respectively.

  The composite service definition information management unit 14 accesses the composite service definition information storage unit 13 and manages the composite service definition information.

  Upon receiving an “access right information acquisition request” from the management terminal 20 or the like, the composite service access right information management unit 15 controls the composite service access right information calculation unit 16 to generate and generate access right information for the composite service. The access right information of the composite service is transmitted to the requester of the access right information acquisition request.

  The composite service access right information calculation unit 16 generates access right information of the composite service by calculation, and sends the calculation result to the composite service access right information management unit 15.

  Specifically, when receiving the “access right information acquisition request” of the composite service, the composite service access right information calculation unit 16 indicates a reachable tree indicating a combination of primitive services from the composite service definition information based on the order information and the branch condition information. Is generated. Then, the composite service access right information calculation unit 16 calculates the logical product (and) of the access right information of the primitive service for each branch of the generated reachable tree. Then, the composite service access right information calculation unit 16 calculates the logical sum (or) of the operation results of all the branches on which the logical product is calculated, and generates composite service access right information. In the present embodiment, the term “reachable tree” includes not only a reachable tree but also a covered tree.

  The composite service access right information calculation unit 16 includes a branch condition handling function 16S. When the branch condition information is included in the composite service definition information, the branch condition handling function 16S generates access right information after the branch for each branch of the reachable tree corresponding to the branch condition information, and all the generated branches It has a function of writing subsequent access right information to the composite service definition information in correspondence with the branch condition information. However, the branch condition handling function 16S is an optional additional item and may be omitted.

  The composite service access right information calculation unit 16 starts calculation processing at the following three timings. That is, (1) when a calculation request is received from the composite service access right information management unit 15, (2) the composite service definition information management unit 14 adds or deletes a composite service or changes the usage relationship between services. (3) The primitive service access right information management unit 12 has changed the access right information of the primitive service.

  The composite service access right information storage unit 17 is a storage device that stores composite service access right information. As shown in FIG. 6, the composite service access right information storage unit 17 stores the access right information of the composite service sent from the composite service access right information management unit 15. Stored in association with the service number and service name.

(Operation of the access right information management device)
Next, the operation of the access right information management apparatus 10 according to the present embodiment will be described with reference to the flowchart of FIG.

  When the access right information management apparatus 10 receives an “access right information acquisition request” from the management terminal 20 or the like (S1), the composite service access right information management unit 15 controls the composite service access right information calculation unit 16.

  In the composite service access right information calculation unit 16, the composite service definition information is acquired from the composite service definition information storage unit 13 (S2).

  Subsequently, as shown in FIG. 8, the composite service access right information calculation unit 16 generates a reachable tree having a branch for each branch condition based on the order information and the branch condition information in the composite service definition information. (S3). Then, the composite service access right information calculation unit 16 acquires the access right information of the service included in the branch for each branch of the reachable tree (S4), and the logical product of the acquired access right information of the service (S4). and) is obtained (S5). Obtaining the logical product operation result corresponds to creating access right information for each branch. When the above processing is performed for all branches, a logical sum (or) is obtained for the operation results of the logical products in all branches (S6). Note that obtaining the logical OR operation result corresponds to creating access right information of a composite service. In addition, when there is duplicate access right information in the operation result, the logical access calculation result may be arranged so that the duplicate access right information is represented in common. Subsequently, the operation result of the logical sum is written in the composite service access right information storage unit 17 as access right information of the composite service (S7). Also, the access right information of the composite service stored in the composite service access right information storage unit 17 is transmitted by the composite service access right information management unit 15 to the management terminal 20 or the like that is the request source of the “access right information acquisition request”. (S8).

  When the branch condition handling function 16S is provided, as shown on the right side of FIG. 9, the branch condition handling function 16S displays the branch condition information in the composite service definition information in parallel with the steps S4 to S7. Access right information of each service after the branch is acquired for each branch of the corresponding reachable tree (S4 '), and logical access of the acquired access right information is calculated (joined with "and") and the access right after the branch Information is created (S5 ′), and the access right information after all the created branches are written in the composite service definition information in correspondence with the branch condition information (S7 ′).

  When the branch condition information is not included in the composite service definition information, the composite service access right information calculation unit 16 generates a reachable tree including one branch (trunk) as shown in FIG. The logical product (and) of the access right information of the primitive service is obtained. The logical product information is written in the composite service access right information storage unit 17 as composite service access right information.

  Next, as a specific example of the operation shown in FIG. 7, a case where the access right information of the composite service X shown in FIG. 11 is generated will be described. In this example, the composite service X is composed of a reachable tree having two branches K1 and K2 by one conditional branch. The first branch K1 includes (1) primitive service 1, primitive service 2, primitive service 4, and primitive service 5. The second branch K2 includes (2) primitive service 1, composite service C, primitive service 4, and so on. It consists of a primitive service 5. The contents of the access right information of each primitive service and the access right information of the composite service are as shown in FIGS. 12 and 13, respectively.

  In such a configuration, the composite service access right information calculation unit 16 concatenates the access right information of the primitive services included in the first branch K1 with “and” as shown in FIG. This can be organized as shown in FIG.

  Similarly, the composite service access right information calculation unit 16 concatenates the access right information of the primitive services included in the second branch K2 with “and” as shown in FIG. This can be organized as shown in FIG.

  Subsequently, the composite service access right information calculation unit 16 shows the access right information linked in the first branch K1 and the access right information linked in the second branch K2 as shown in FIG. As shown in FIG. If the connected access right information is arranged so that the common part is enclosed in parentheses, it is as shown in FIG. Then, the organized result is newly registered in the composite service access right information storage unit 17 as access right information of the composite service X, as shown in FIG.

  Next, as a specific example of the operation shown on the right side of FIG. 9, a case where access right information after the branch of the composite service X shown in FIG. 16 is generated will be described. The operations in steps S1 to S3 are as described above. In step S2, composite service definition information having the data structure shown in FIG. 17 is acquired, and in step S3, a reachable tree having the data structure shown in FIG. 18 is created.

  Subsequently, in parallel with steps S4 to S5, the branch condition handling function 16S obtains access right information for each service after the branch for each branch of the reachable tree corresponding to the branch condition information in the composite service definition information. Then (S4 ′), as shown in FIGS. 19A and 19B, the access right information after the branch is created by calculating (joining with AND) the acquired access right information (and combined with “and”) (S4 ′). S5 ′). Note that the access right information shown in FIGS. 19A and 19B does not change even if they are arranged.

  In parallel with step S7, the branch condition handling function 16S writes the access right information after all the created branches to the composite service definition information in association with the branch condition information (S7 '). As a result, the composite service definition information becomes information having the data structure shown in FIG. 21, as conceptually shown in FIG. Thereafter, the branch condition handling function 16S ends the process.

(Effect of access right information management device)

  In short, according to the access right information management apparatus 10, even if the access right information of the primitive service is changed, the access right information of the composite service is automatically changed. Can do.

  Further, since the access right information of the composite service is automatically generated in the access right information management apparatus 10, it is not necessary to set the access right information in the construction of the composite service by the end user.

  In recent years, there has been an increase in the situation in which a user creates a new composite service by combining a plurality of primitive services and composite services by mashup. In other words, a situation where a lot of access right information is generated and discarded is increasing. Even in such a situation, according to the access right information management apparatus 10 according to the present embodiment, even if a large number of access right information is generated and discarded, it is possible to avoid omissions and errors in the access right information.

  In the access right information management apparatus 10 according to the present embodiment, the composite service definition information storage unit 13 stores access right information in association with the branch condition information. In other words, the operation result of the logical product of the access right information after the branched portion is stored.

  As a result, when executing the branch processing of the composite service, the access permission is performed based on the access right information corresponding to the branch condition information, so that the user is notified of the authentication result early and the convenience is improved. be able to.

  For example, as a composite service, an employee business trip service composed of primitive services of station front display processing, employee schedule management processing, expense processing, and business trip approval processing, as shown in FIG. 22, is defined in the composite service definition information storage unit 13. Suppose that In addition, branching conditions 1 and 2 are defined as whether or not the employee belongs to the headquarters in the employee schedule management process. For employees who do not belong to the headquarters (branch condition 2), expense processing Suppose that access to is not allowed. In other words, in the composite service definition information, it is assumed that access right information indicating “and supervisor” is written in association with the branch condition 2.

  In this case, an employee who does not belong to the head office and is not a supervisor can understand that the employee business trip service cannot be used at the condition branching stage without proceeding to the expense processing stage. Therefore, as a result, convenience to the user can be improved.
