Description

The present invention relates to a data processing method and a data processing program.

In stream processing, a technology has emerged to assemble processing using data necessary for processing. As a result, data can be shared in stream processing, and access control is performed to determine whether or not each data is accessible.

JP 2015-158943 A WO2015/136843

However, the method of determining whether or not each piece of data is accessible causes performance problems, such as an increase in processing load, in stream processing that is performed from moment to moment.

In stream processing, the processing result is output using the data to be updated and the data to be referenced. is checked 11 times.

Also, in stream processing, since data is updated frequently, a check is made as to whether or not access is possible each time.

One aspect sets access control that does not increase the load in stream processing.

In one aspect, receiving a setting request for a first program that defines processing to be executed in response to the data being updated, and processing the data for the first program based on pre-defined plug-in information. determining the presence or absence of access permission for one program, and when it is determined that the access permission for the first program is granted, generating a second object including the first program, and in the first object, A second program is generated for copying the data to the second object, and access permission information for the second program is set for the second object.

In one aspect, it is possible to set access control that does not increase the load in stream processing.

An embodiment will be described below with reference to the drawings. However, the embodiments shown below are merely examples, and are not intended to exclude the application of various modifications and techniques not explicitly described in the embodiments. In other words, the present embodiment can be modified in various ways without departing from the spirit of the embodiment.

Also, each drawing does not mean that it has only the constituent elements shown in the drawing, but can include other functions and the like.

In the following figures, the same reference numerals denote the same parts, so the description thereof will be omitted.

[A] Related Example FIG. 1 is a diagram illustrating reference control in stream processing as a related example.

Each of the plurality of objects 6 that constitute stream processing includes one or more states 61 (which may also be referred to as “data”) and one or more processing units 62 .

In the example shown in FIG. 1, object #1 includes processing units #11 and #12. Processing units #11 and #12 are permitted to refer to two states 61, respectively. Object #2 includes processing unit #21, and object #3 includes processing unit #31.

Processing unit #11 writes to object #2 using two states 61 that are permitted to be referenced. In addition, processing unit #12 uses two permitted states 61 to write to object #3.

Here, if the state 61 is shared within the object 6, there is a possibility that the processing unit #11 accesses the state 61 for which reference is not permitted, as indicated by symbol A1.

Therefore, as indicated by symbol A2, access restriction is implemented to prevent access to the state 61 for which reference is not permitted.

FIG. 2 is a diagram illustrating update control in stream processing as a related example.

In the example shown in FIG. 2, object #1 includes processing unit #11 and object #3 includes processing unit #31. Processing units #11 and #31 are permitted to refer to two states 61, respectively. Object #2 includes processing unit #21, and object #4 includes processing unit #41.

Processing unit #11 writes to object #2 using two states 61 that are permitted to be referenced. In addition, processing unit #31 writes to object #4 using two states 61 that are permitted to be referenced.

Here, as indicated by reference symbol B1, processing unit #11 may write to object #4 for which writing is not permitted.

Therefore, as indicated by reference character B2, access restriction is implemented so as to prevent access to object #4 for which writing is not permitted.

FIG. 3 is a diagram for explaining determination of whether or not access is permitted in stream processing as a related example.

In the example shown in FIG. 3, object #1 includes states #11 to #13 and processing units #11 and #12. Processing section #11 is permitted to refer to states #11 and #12, and processing section #12 is permitted to refer to states #12 and #13. Also, object #2 includes state #21, object #3 includes state #31, and object #4 includes state #41.

Processing section #11 is permitted to write to objects #2 and #3, and processing section #12 is permitted to write to object #4.

As indicated by symbol C1, permission (may also be referred to as “reference permission”) is set for each state 61 .

As indicated by symbol C2, the processing unit 62 checks whether access is permitted when using the state 61 (see symbol C2). In the illustrated example, processing unit #11 is permitted to access state #11.

On the other hand, when the processing unit 62 attempts to access the state 61 for which access is not permitted, the access is denied, as indicated by symbol C3. In the illustrated example, processing unit #11 is not permitted to access state #13, and therefore cannot access state #13.

As indicated by symbol C4, the processing unit 62 checks whether writing to the state 61 of the object 6 as the write destination is permitted at the time of writing. In the illustrated example, processing unit #11 is permitted to write to state #21 of object #2.

On the other hand, as indicated by symbol C5, when the processing unit 62 attempts to write to the state 61 of the object 6 for which writing is not permitted, the writing is rejected. In the illustrated example, processing unit #11 is not permitted to write to state #41 of object #4, so it cannot write to state #41.

FIG. 4 is a diagram illustrating registration processing of the plug-in 602 in stream processing as a related example.

In the example shown in FIG. 4, plug-in 602 (which may be referred to as "Program A") executes in object #1 and outputs the result of the addition to object #2.

State list 601 indicates that program A is executed when x or y of state 61 in object #1 is updated. Also, the state list 601 indicates that the states 61 that the program A can refer to are x and y.

Program A and state list 601 are registered in object #1 (see symbol D1). As a result, a processing unit 62 (which may be referred to as “processing unit A”) that outputs s, which is the sum of x and y, as state 61 is defined in object #1 for object #2. be.

Also, by registering the program A and the state list 601 in the object #1, an execution condition table 63 indicating that the program A can access the states 61 of x and y is generated.

FIG. 5 is a diagram illustrating a first example of the operation of the plug-in 602 in stream processing as a related example.

As indicated by symbol E1, the state 61 of the object 6 is updated by inputting data 600 to the object 6 from the outside.

In the illustrated example, as indicated by symbol E2, "1", "2", and "text" are input to the x, y, and z states 61 of object #1, respectively, and program A inputs object #2. "3" is output to state 61 of s as the sum of x and y.

Here, in the execution condition table 63, the program A is associated with states 61 of x and y. That is, program A is executed when state 61 of x or y is updated.

Program A may be executed by the plug-in execution unit 60 referring to the execution condition table 63 . The plug-in execution unit 60 relays reference and output of the state 61 from the program A, and reads and writes the state 61 in the object 6 .

FIG. 6 is a diagram illustrating registration processing of the processing unit 62 and registration of access permission information 64 in stream processing as a related example.

As indicated by symbol F1, program A as a plug-in 602 and state list 601 of (x, y) are registered in object #1. Program A outputs the result of the addition to s, state 61 of object #2. State list 601 represents executing program A when x or y is updated. This creates an execution condition table 63 indicating that program A can access states 61 of x and y.

Access permission information 642 indicating that program A may access states 61 of x and y is registered in object #1, as indicated by reference numeral F2. As a result, access permission information 64 is generated indicating that program A is permitted to access x and y, but that program A is not permitted to access z.

Furthermore, access permission information 642 indicating that program A may access state 61 of s is registered in object #2, as indicated by reference numeral F3. As a result, access permission information 64 indicating that s is permitted to be accessed by program A is generated.

FIG. 7 is a diagram illustrating a second example of the operation of the processing unit 62 in stream processing as a related example.

As indicated by G1, x, y, z, which is the state 61 of object #1, is updated.

As a result, as indicated by G2, the access permission information 64 is referenced to check whether program A is permitted to access states x and y of object #1, and program A performs calculation. The access permission information 64 corresponding to object #1 registers that access by program A is permitted to x and y, but access by program A is not permitted to z.

Then, as indicated by G3, whether or not access to state s of object #2 is permitted is checked, and the execution result of program A is output to state s, which is state 61 of object #2. Access permission information 64 corresponding to object #2 registers that access by program A is permitted for s.

Here, program A is executed by the plug-in execution unit 60 . Also, the plug-in execution unit 60 references the execution condition table 63 from the program A and outputs the calculation results. Furthermore, the plug-in execution unit 60 reads and writes the state 61 of the object 6 based on the access permission information 64 .

[B] Example of Embodiment [B-1] Example of System Configuration FIG. 8 is a diagram illustrating an overview of stream processing in a related example and an example of an embodiment.

Reference H1 indicates three objects 6 (which may also be referred to as "processing spaces #1 to #3") in the related example.

The processing space #1 includes three states 61 and one processing section 62 (processing section #1). Processing spaces #2 and #3 each contain one state 61 . A processing unit 62 in processing space #1 is permitted to access two states 61 in processing space #1, one state 61 in processing space #2, and one state 61 in processing space #3.

On the other hand, H2 indicates five objects 2 (which may also be referred to as "processing spaces #1 to #5") in one example of the embodiment. The number of the processing space and the processing unit is combined with H1, which is an implementation example in the embodiment.

In the stream processing in one example of the embodiment, by associating the processing unit 22 with the object 2 (in other words, processing space), the object 2 receives only the processing result of the associated processing unit 22. Thus, control is performed to limit the destination.

Further, the processing unit 22 that performs input to the object 2 transmits the data to be used by the object 2 at the time of updating, thereby restricting the data to be used.

In the example indicated by symbol H2, the processing space #1 includes three states 21 and two processing units 22 (also referred to as "processing units #11 and #12"). Also, the processing space #5 includes two states 21 and one processing unit 22 (which may also be referred to as “processing unit #1”). Furthermore, one state 21 is included in each of the processing spaces #2 to #4.

As indicated by symbol H21, processing unit #11 in processing space #1 is permitted to access two states 21 in processing space #1 and is not permitted to access two states 21 in processing space #5. Allowed.

On the other hand, as indicated by symbol H22, processing unit #12 in processing space #1 is permitted to access two states 21 in processing space #1, but is not permitted to access processing space #5. do not have.

As indicated by symbol H23, processing unit #1 in processing space #5 can access two states 21 in processing space #5, and can access each state 21 in processing spaces #2 and #3. is allowed.

On the other hand, as indicated by symbol H24, processing unit #1 in processing space #5 is not permitted to access state 21 in processing space #4.

FIG. 10 is a block diagram schematically showing a functional configuration example of the information processing device 1 shown in FIG.

The process accepting unit 111 accepts a process from the user and stores the processing unit 22 used for the process in the process storage unit 141 . The processing reception unit 111 refers to, for example, the plug-in information 27 of FIG. exit. If access is permitted, the processing space control unit 112 is requested to register the processing unit 22 .

The processing space control unit 112 reads the plug-in 202 and the state list 201 (both of which will be described later with reference to FIG. 11) stored in the processing storage unit 141, creates the object 2, sets the plug-in 202, and configures the setting. The plug-in 202 for copying the state of the state list 201 to the destination object 2 is read from the copy processing storage unit 142 and set. The plug-in 202 of the copy processing storage unit 142 may be prepared in advance, or may be dynamically created in the processing space control unit 112 . Details of the processing space control unit 112 will be described later with reference to FIG.

The process execution unit 113 uses the object 2 defined by the processing space control unit 112 to execute stream processing. Details will be described later with reference to FIG.

FIG. 11 is a diagram illustrating registration of the processing unit 22 and registration of the linking information 23 in the information processing apparatus 1 shown in FIG.

Assume that objects #1 and #2 indicated by symbol H1 in FIG. 8 are defined as an initial state.

As indicated by symbol I1, the plug-in 202 of program A, the state list 201 of (x, y), and the linking information 23 are registered in object #1. This linking information 23 is set in the access permission information 24 of the program A. FIG. Object #m is generated and program A is set by processing space control unit 112 . Further, the processing space control unit 112 sets the program M to the object #1, sets the access permission information 24 of the program M, associates the object #m with the program M, and sets the access permission information 24 of the program M. m is set to the linking and the linking 23 of the object #m. Also, as indicated by reference numeral I2, the linking information 23 is registered in the object #2. A is registered as the linking information 23 of the object #2. At reference numeral I1, since "a" is set in the linkage of the access permission information 24 of program A, program A has the right to access object #2.

That is, the process accepting unit 111 accepts a setting request for the state list 201 and the first program defining the process to be executed in response to the update of the state list 201 . Further, the process receiving unit 111 determines whether or not the first program is permitted to access the state list 201 based on the plug-in information 27 defined in advance (described later with reference to FIG. 15). When it is determined that the access permission for the first program is granted, the processing space control unit 112 generates the second object 2 including the first program, and transfers the data in the first object 2 to the second object. A second program to be copied to the object 2 is generated, and second access permission information 24 of the second program for the second object 2 is set.

12A and 12B are diagrams for explaining the operation of the plug-in in the information processing apparatus 1 shown in FIG.

As indicated by J1, the state 21 of the object #1 is updated by inputting data from the outside.

As indicated by J2, the program M is executed according to the updated state 21, and the x and y states 21 of the object #m are updated. The update of the state 21 is executed only when the association between the association information 23 and the access permission information 24 is checked and the associations match. Since the link in the access permission information 24 of the program M is m and the link information 23 of the object #m is m and match, the states 21 of x and y of the object #m are updated.

As indicated by J3, program A is executed according to the updated state 21, and the state 21 of s of object #2 is updated. The update of the state 21 is executed only when the association between the association information 23 and the access permission information 24 is checked and the associations match. Since the link in the access permission information 24 of the program A is a and the link information 23 of the object #2 is a and they match, the state 21 of s of the object #2 is updated.

That is, in the second program, when the state list 201 is updated, the process execution unit 113 refers to the access permission information 24 and determines whether or not the second program is permitted to access the second object 2 . judge. Also, the process execution unit 113 copies the state list 201 to the second object 2 when it is determined that the second program is permitted to access the second program. Furthermore, the process execution unit 113 executes specified processes in the first program of the second object 2 when the state list 201 is copied.

The process execution unit 113 executes the program A according to the state list of the access permission information 24 and the update of the state 21 . Reference and output of the state 21 from the program A are performed via the processing execution unit 113, and the reading and writing of the state 21 of the object 2 are performed by the processing execution unit 113 instead of being directly performed by the program A. In addition, the processing execution unit 113 refers to the linking of the access permission information 24 only when writing to another object 2 to check whether access is permitted.

In other words, the process executing unit 113 copies only the updated state 21 in the state list 201 to the second object 2 in the second program, thereby increasing the number of state 21 updates. can be reduced.

13A and 13B are diagrams for explaining screen display examples for user registration and login in the information processing apparatus 1 shown in FIG. A user here is a user to whom an access right is granted. Access rights are granted to each user, and by logging in, the user can create objects and register plug-ins according to the set access rights.

The user registration screen 31 is a screen for registering a new user ID and password. The ID and password registered using the user registration screen 31 are managed as user information 25 .

The login screen 32 is a screen for accepting login of a user registered in the user information 25 . When an ID and password are entered on the login screen 32, the user information 25 is referenced, and if the entered ID and password match the ID and password registered in the user information 25, login is permitted.

FIG. 14 is a diagram for explaining a screen display example for object registration in the information processing apparatus 1 shown in FIG.

The object creation screen 33 is a screen for creating and displaying a new object 2 on the object operation screen 34 by inputting an object ID.

The object operation screen 34 displays the object 2 and controls transition to the object creation screen 33 , access permission screen 35 and state creation screen 36 .

By selecting the state 21 of the object 2 on the object operation screen 34, an access permission screen 35 is displayed. The access permission screen 35 is a screen for registering users permitted to access the state 21 .

When the object 2 is selected on the object operation screen 34, a state creation screen 36 is displayed. The state creation screen 36 is a screen for inputting the state 21 to be added to the object 2 .

Object information 26 is generated by inputting information to the object creation screen 33 , access permission screen 35 and state creation screen 36 . The object information 26 is associated with an object ID, an owner, a state, and an authorized user.

Object ID is an identifier of object 2 . The owner is the ID of the user who created object2. The state is state 21 registered in object 2 . Authorized User is the ID of a user who is authorized to access state 21 .

FIG. 15 is a diagram for explaining a screen display example for adding a plug-in in the information processing apparatus 1 shown in FIG.

FIG. 15 shows an operation by a user U2 other than the user U1 who created the object 2 as the owner in FIG.

By inputting the object ID on the object creation screen 33 , a new object 2 is created and displayed on the object operation screen 34 . In the illustrated example, object #O2 is newly displayed.

Here, on the object operation screen 34, only the states 21 to which each user is permitted to access are displayed. In the object #O1 of the object information 26, the states permitted to the user U2 are x and y, so only the state 21 of x and y is displayed in the object #O1 of the object operation screen 34, and z is not displayed. .

When the object 2 is selected on the object operation screen 34, a plug-in registration screen 37 is displayed. The plug-in registration screen 37 is a screen for entering the plug-in 202 to be registered in the object 2 . On the plug-in registration screen 37, the state 21 to be used, the plug-in file, the linkage, and the linked object 2 can be registered.

By adding the object #O2 on the object creation screen 33, information about the object #O2 is added to the object information 26 in the illustrated example. Description of creation of the state s is omitted.

Plug-in information 27 is generated by registration of the processing unit 22 through the plug-in registration screen 37 . In the plug-in information 27, a plug-in ID, an owner, a link, an object ID, and a state are associated with each other.

A plug-in ID is an identifier of the processing unit 22 . The owner is the ID of the user who registered the processing unit 22 . A link indicates a link with another object 2 . The object ID is the identifier of the object 2 with which the processing unit 22 is registered. The state is the state 21 used by the processing unit 22 . Since the plug-in information 27 is created according to the authorized user of the object information 26, only authorized states are registered as the state of the plug-in information 27. FIG. Therefore, the plug-in information 27 also functions as plug-in access permission information.

[B-2] Operation Example The process of creating a processing space in the information processing apparatus 1 shown in FIG. 9 will be described with reference to the flowchart (steps S1 to S6) shown in FIG. 11 is a detailed flowchart of the processing space control unit 112 of FIG. 10;

The processing space control unit 112 receives a processing registration request registered by the user from the processing receiving unit 111 (step S1).

The processing space control unit 112 creates an object 2 as a processing space based on the registration from the user (step S2).

The processing space control unit 112 registers a process of copying the target state in the created processing space (step S3). The copy process is acquired from the copy process storage unit 142 .

The processing space control unit 112 associates the created processing space with the process of copying the target state (step S4).

The processing space control unit 112 registers the requested processing in the created processing space (step S5). The processing requested to be registered is acquired from the processing storage unit 141 .

Note that the processing space control unit 112 creates the object 2 and registers processing with the processing execution unit 113 . Further, when the state 21 is updated, the process execution unit 113 refers to the access permission information 24 and executes the plug-in.

[B-3] Effect FIG. 17 is a diagram for explaining the load due to access determination in a related example.

FIG. 17 exemplifies stream processing for calculating the velocity based on the input of the position of the object. In this example, latitude and longitude are input, the difference from the previous latitude and longitude and the difference between the previous time and the current time are used to calculate the speed, and when the threshold is exceeded, the speed is output. Save the latitude/longitude and current time as the previous latitude, previous longitude, and previous time for the next speed calculation.

In the illustrated example, object #1 contains six states 61 and object #2 contains one state 61 . In other words, the number of pieces of access control information indicating whether or not access to each state 61 is permitted from the processing unit 62 is 6 data for object #1 and 1 data for object #2, so a total of 7 data.

The processing unit 62 of the object #1 performs nine access determinations in total, 6 times for reading and 3 times for writing, for each state 61 of the object #1, and writes to the state 61 of the object #2. Perform one access determination. As a result, a total of 10 access determinations are performed.

FIG. 18 is a diagram for explaining the load due to access determination in the information processing apparatus 1 shown in FIG.

FIG. 18 also exemplifies stream processing for calculating the velocity based on the input of the position of the object.

In the illustrated example, the processing unit 22 of the object #1 performs one access determination with respect to the object #3, and the processing unit 22 of the object #3 performs one access determination with respect to the object #2. As a result, a total of two access determinations are performed.

Also, since the access control information in object #3 is 1 data and the access control information in object #2 is 1 data, the total number of access control information is 2 data.

As described above, in the stream processing in one example of the embodiment, the number of times of access determination and the number of access control information can be reduced compared to the stream processing in the related example.

The process accepting unit 111 accepts a setting request for the state list 201 and the first program defining the process to be executed in response to the update of the state 21 of the state list 201 . Further, the process receiving unit 111 determines whether or not the first program is permitted to access the state list 201 based on the plug-in information 27 defined in advance. When it is determined that the access permission for the first program is granted, the processing space control unit 112 generates the second object 2 including the first program, and transfers the data in the first object 2 to the second object. A second program to be copied to the object 2 is generated, and access permission information 24 of the second program for the second object 2 is set.

As a result, in stream processing, access control can be set that does not increase the load.

In the second program, when the state 21 of the state list 201 is updated, the process execution unit 113 refers to the access permission information 24 and determines the access permission of the second program to the second object 2. Determine presence/absence. Also, the process execution unit 113 copies the state 21 of the state list 201 to the second object 2 when it is determined that the second program is permitted to access the second program. Further, the process execution unit 113 executes specified processes in response to copying of the state 21 of the state list 201 in the first program of the second object 2 .

As a result, access control can be performed in stream processing without increasing the load.

The process executing unit 113 copies only the updated state 21 in the state list 201 to the second object 2 in the second program.

Thereby, unnecessary access to the state 21 of the state list 201 can be suppressed.

[C] Modification In the modification, the process of copying data to the object 2 is switched, so that updating of data is stopped or updated according to conditions.

FIG. 19 is a block diagram schematically showing a functional configuration example of the information processing device 1 as a modified example.

In the functional configuration shown in FIG. 19, a usable data comparison table 143 is provided as compared with the functional configuration example in the exemplary embodiment shown in FIG.

Data to be provided for processing is registered in the available data comparison table 143 . The data source to be copied is changed from the available data comparison table 143, and the copy process is registered. The copy process itself may be changed. The copy process ID indicates the ID of the copy process plug-in, and the plug-in is saved in the copy process save unit 142 .

In the usable data comparison table 143, one processing space ID is associated with one or more input data and output data, and one copy processing ID.
When there is an output that matches the plug-in state list 201 registered by the user, the copy process of the copy process ID is used. In this example, when the state list 201 includes data #A and data #B, the plug-in with the copy process ID of #11 is used.

FIG. 20 is a diagram for explaining the switching operation of the data copying process in the information processing apparatus 1 shown in FIG.

The user registers the processing unit 22 with the data #A and data #B of the processing space ID #1 as the state list 201 . Since the available data comparison table 143 includes the data #A and data #B items in the output for the processing space ID #1, the processing unit 22 of the processing space ID #1 has the copy processing storage unit 142 , and registers the state list 201 with data #1, data #2, and data #3 in processing space ID #1. The processing unit 22 with processing space ID #1, for example, provides data #1 and #2 to data #A and #B, respectively, with data #3 as a condition. As a result, it is possible to change the method of providing data to the processing unit 22 of the subsequent processing space ID#2.

According to the information processing apparatus 1 in the modified example, in addition to the effects that can be obtained in the example of the embodiment described above, for example, the following effects can be obtained.

The second program copies the states 21 to the second object 2 only when at least some of the states 21 specified by the state list 201 satisfy a predetermined condition.

As a result, the process of copying data to the object 2 is replaced, so that updating of data can be stopped or updating can be performed according to conditions. It is also possible to provide data after performing calculations and processing data instead of simple copying.

Each configuration and each process of the present embodiment can be selected as necessary, or may be combined as appropriate.
