Description

  The present invention provides a usage agreement that explains to a user how the data is processed and processed when an application that uses the data stored in the terminal and / or cloud is executed. The present invention relates to an information generation apparatus that generates an application that actually performs processing, an information generation method and an information generation program used in the information generation apparatus.

  When an application uses specific data that the user has, it is desirable that the user obtain a use permission. By clarifying what data is used for what purpose and how it is used, the user trusts the application and its developer, and provides personal data held by the user. On the other hand, the user can avoid providing personal data to the application and the developer who have distrust by not using the application.

  Currently, the license agreement is written by the application developer, but it is not guaranteed that the application and the license agreement are correctly associated. Therefore, even if it is a malicious application creator, there is a problem that it is only possible to believe the contents of the license agreement. On the other hand, there is also a problem that a disadvantage to an application developer that the application cannot be used because an appropriate trust cannot be obtained even though the behavior is correct.

  As a method for associating the license agreement with the behavior of the application, important operations such as access to phone book data and Internet access are limited to operations with specific identifiers as operations requiring privileges, and Android OS (registered) is a method to explicitly indicate to the user the data to be accessed and the operation to be performed by analyzing the identifier described in the application and comparing the identifier to be used with the description of the declared file. Trademark) and the like.

  The problem with the current model is that each license is handled independently, so the user cannot understand whether or not the processes permitted by the license are related, and for which data It is unclear which process is being executed. For example, when permission is required for access to phone book data and Internet access, it is ensured that the application includes processing for executing access to phone book data and Internet access. It is not possible to know whether the book data is transmitted to the outside or used only within the terminal. In the current model, it is possible to determine which process is being executed for which data based on the license agreement that is not associated with the application, which is written by the application developer. It can be said that the usage agreement text not associated with is incomplete as the usage agreement information. Even when only a part of the data is used, or when the data is processed and aggregated and stored on the server, it is difficult to comprehensively associate the processing with the identifier, and the usage permission is guaranteed to operate. Cannot be expressed as

  Embodiments according to the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 shows a system in which an information generation apparatus 10 according to the first embodiment is used. The system shown in FIG. 1 includes an information generation device 10 and an agent 20.

  FIG. 2 is a block diagram showing a functional configuration of the information generating apparatus 10 shown in FIG. The information generation apparatus 10 illustrated in FIG. 2 includes a functional block registration / management unit 11, an operation / display unit 12, and an arithmetic processing unit 13.

  The functional block registration / management unit 11 registers functional blocks in accordance with instructions from the arithmetic processing unit 13 and manages the registered functional blocks. A functional block is a block containing a specific function and / or object. The functional blocks are roughly classified into two types: a first functional block that performs “data source output” and a second functional block that performs “processing”.

  The first functional block cooperates with the agent 20 to make the data held by the agent 20 and the data collected by the agent 20 usable on the application. Only through the first functional block, the agent 20 provides data to the application. The second functional block executes all processes other than “data source output”, for example, statistical processing, narrowing down, and data transmission.

  Each function block is provided with a use permission message used for use permission. The type of data to be used is described in the usage permission message assigned to the first functional block. Further, the usage permission message given to the second functional block is associated with the processing content.

  The operation / display unit 12 is an interface with the outside, and receives operations from an application developer and a system administrator. Further, the operation / display unit 12 displays the function blocks, applications, usage agreements, etc. registered in the function block registration / management unit 11.

  The developer selects a functional block displayed on the operation / display unit 12 and connects the functional blocks selected on the operation / display unit 12.

  Further, the operation / display unit 12 registers the function block approved by the system administrator or a trusted third party in the function block registration / management unit 11.

  An example of functional block registration processing by the operation / display unit 12 will be specifically described. The operation / display unit 12 displays the source code of the first functional block. The system administrator and a trusted third party are obtained by the first functional block through visual inspection of the source code displayed on the operation / display unit 12 or confirmation through execution of the first functional block. It is determined in advance whether or not the data type matches the type of data used in the application. If there is a match, the system administrator and the trusted third party approve the first functional block. The operation / display unit 12 causes the functional block registration / management unit 11 to register the approved first functional block.

  The operation / display unit 12 displays the source code of the second functional block. The system administrator and a trusted third party refer to the source code displayed on the operation / display unit 12 to determine in advance whether or not the processing content of the second functional block corresponds to the usage permission message. To do. If so, the system administrator and the trusted third party approve the second functional block. The operation / display unit 12 causes the function block registration / management unit 11 to register the approved second function block.

  The arithmetic processing unit 13 includes, for example, a CPU (Central Processing Unit), and a storage area for programs and data for the CPU to execute processing such as ROM (Read Only Memory) and RAM (Random Access Memory). The arithmetic processing unit 13 causes the CPU to execute a program, thereby realizing an application generation unit 131, a license agreement generation unit 132, and a signature addition unit 133.

  When the arrangement of functional blocks is determined on the operation / display unit 12 and an arbitrary output can be obtained, the developer gives an application generation instruction to the application generation unit 131 via the operation / display unit 12. When an application generation instruction is given from the developer, the application generation unit 131 considers each function block as a node and a connection portion between each function block as a directed edge, and starts a topological sort. The topological sort is a process for confirming whether the graph has a cycle. As a result of the topological sort, when the graph is an acyclic directed graph, the application generation unit 131 proceeds to a function block connection process. If the graph has a cycle as a result of the topological sort, the application generation unit 131 outputs an error. This is because the usage agreement text is generated for all routes by the usage agreement text generation unit 132, and thus is generated infinitely when there is a closed circuit. For example, when the combination of functional blocks is a graph configuration as shown in FIG. 3, since a closed circuit is formed by B → C → B, A → B → C → D, A → B → C → B → C → D, A → B → C → B → C → B → C → D,... Therefore, an infinite usage permission sentence is generated for each route.

  The application generation unit 131 confirms whether the input format between the functional blocks constituting the graph determined to be an acyclic directed graph by the topological sort matches the output format. If they match, the application generation unit 131 connects the functional blocks by passing a return value as an argument between the functional blocks. Here, the first functional block has an output format, and the second functional block has an output format and an input format. Note that the second functional block may have a plurality of input formats and a plurality of output formats.

  Note that the second functional block may have parameters, and numerical values and character strings may be freely changed. For example, in the case of a functional block that narrows down according to the data generation time, by specifying parameters such as {epoc_start: xxx, epoc_end: yyy}, it is possible to narrow down the range to narrow down without preparing multiple functional blocks. It is possible to change. However, the parameter must also be included in the usage permission message.

Further, the developer inputs a usage agreement text generation instruction to the usage agreement text generation unit 132 via the operation / display unit 12. When the usage agreement text generation instruction is input, the usage agreement text generation unit 132 generates a usage agreement text based on the usage agreement message assigned to each function block to be connected. At this time, the license agreement generation unit 132 may generate a license agreement so that the license agreement messages written in the functional block are listed, or the license agreement message that has been enumerated is shaped to be easy to read. May be generated. For example, when the type of data acquired by the first functional block is A and the processing content of the second functional block is B, the usage permission sentence generation unit 132 displays “A: B ₁ , B ₂ , B _3. ... ”Or“ Acquire A, perform B ₁ and then perform B ₂ and perform B ₃ ”. This is due to the processing function of the information generation apparatus 10.

  The signature assigning unit 133 uses a secret key implemented in a format such as a hash function and an encryption key to sign the application generated by the application generating unit 131 and the license agreement generated by the license agreement generating unit 132. Is granted. The signature may be a general electronic signature. When the application developer and the usage agreement are correctly signed, the application developer distributes the signed application and the usage agreement to the user.

  When the agent 20 receives a request for compiling the application from the user, the agent 20 first confirms the signature attached to the application and the license agreement. As a result, the agent 20 confirms that the application and the usage agreement have not been tampered with. When the agent 20 confirms that the application and the usage agreement have not been tampered with, the agent 20 presents the usage agreement to the user. When the user grants permission to the contents of the license agreement, the user compiles the application.

  Next, the operation of the information generating apparatus 10 configured as described above will be specifically described. FIG. 4 shows a sequence diagram when the information generating apparatus 10 registers a functional block.

  First, the application developer uploads a functional block to the operation / display unit 12 (sequence S41). The operation / display unit 12 displays the function block source code and the like, and accepts approval from the system administrator or the like (sequence S42). When receiving an approval from the system administrator or the like (sequence S43), the operation / display unit 12 causes the functional block registration / management unit 11 to register the approved function block (sequence S44).

  FIG. 5 shows a flowchart when the information generating apparatus 10 registers a functional block.

  First, the information generating apparatus 10 receives a new functional block by the operation / display unit 12 (step S51). The operation / display unit 12 waits for processing on the functional block and displays the source code of the functional block and the like (step S52).

  The operation / display unit 12 determines whether or not the source code to be displayed is approved by the system administrator or the like (step S53). If there is approval (Yes in step S53), the operation / display unit 12 registers the functional block in the functional block registration / management unit 11 (step S54), and ends the process. When there is no approval (No in Step S53), the operation / display unit 12 rejects the registration of the functional block (Step S55) and ends the process.

  FIG. 6 shows a sequence diagram when the information generating apparatus 10 generates an application and a license agreement.

  First, the information generating apparatus 10 displays the function blocks registered in the function block registration / management unit 11 on the operation / display unit 12 (sequence S61). The operation / display unit 12 receives an operation from an application developer. FIG. 7 shows a display example of the operation / display unit 12. The functional blocks read from the functional block registration / management unit 11 are displayed on the right functional block selection palette. The developer assembles an application by selecting a functional block from the selection palette and connecting the selected functional blocks. The operation / display unit 12 displays an application / usage license generation button. When the assembly of the application is completed, the developer clicks an application / usage license generation button (sequence S62). When the application / use permission sentence generation button is clicked, the operation / display section 12 outputs an application generation instruction and a use permission sentence generation instruction to the arithmetic processing section 13 (sequence S63).

  When receiving the application generation instruction, the arithmetic processing unit 13 performs a topological sort (sequence S64). When the topological sort determines that the graph is an acyclic effective graph, the arithmetic processing unit 13 generates an application by connecting the functional blocks (sequence S65). In addition, the arithmetic processing unit 13 generates a usage agreement text using the usage agreement message given to the functional block (sequence S66).

  In addition, the arithmetic processing unit 13 gives a signature to the generated application and usage agreement (sequence S67). The arithmetic processing unit 13 outputs the generated application and usage agreement to the operation / display unit 12 (sequence S68).

  The operation / display unit 12 displays the application and the usage agreement to the developer (sequence S69).

  FIG. 8 shows a flowchart when the information generation apparatus 10 generates an application and a usage agreement.

  First, the information generating apparatus 10 reads out the functional blocks registered in the functional block registration / management unit 11 and displays the read-out functional blocks on the operation / display unit 12 (step S81). The operation / display unit 12 stands by while the developer combines the functional blocks (step S82). When the generation button shown in FIG. 7 is clicked, the operation / display unit 12 outputs an application / usage license generation instruction to the arithmetic processing unit 13 so as to start generating the application and the usage agreement text (step S83). .

  When the generation of the application and the usage agreement is instructed, the arithmetic processing unit 13 determines whether or not a closed path is detected using the topological sort (step S84). If detected (Yes in step S84), the arithmetic processing unit 13 outputs an error (step S85) and ends the process. When the closed circuit is not detected (No in step S84), the arithmetic processing unit 13 determines whether or not the input format and the output format between the combined functional blocks match (step S86). If they match (Yes in step S86), the arithmetic processing unit 13 connects the functional blocks and generates an application (step S87). Further, the arithmetic processing unit 13 generates a use permission sentence (step S88). If the input format and the output format between the combined functional blocks do not match (No in step S86), the process proceeds to step S85.

  When generating the application and the usage agreement text, the arithmetic processing unit 13 gives a signature to the generated application and usage agreement text (step S89). The arithmetic processing unit 13 causes the operation / display unit 12 to display the application to which the signature is attached and the usage agreement (step S810).

  As described above, in the first embodiment, the arithmetic processing unit 13 generates an application by combining functional blocks including functions and objects, and at the same time, relates to the entire processing from the usage permission message previously given in the functional block. A license agreement is generated. As a result, a combined functional block is generated as an application program, and a license message is generated from a license message given to the linked functional block. Can be generated.

  In the first embodiment, the signature assigning unit 133 assigns a signature to the application and the usage agreement when generating the application and the usage agreement in order to secure the execution contents of the application and the contents of the usage agreement. Like to do. This makes it possible to ensure that the content generated by the system has not been tampered with when executing the application. In other words, it is possible to ensure the validity of the application and the license agreement.

  Further, in the first embodiment, the arithmetic processing unit 13 does not allow an application having a loop structure path by calculating whether topological sorting is possible for a graph to which functional blocks are connected. ing. As a result, the generated usage agreement is always associated with the application. In addition, it is possible to suppress combinations that generate infinite use permission sentences as combinations of functional blocks.

  Until now, a method of generating a program by combining an object having a function and a function has been realized by a component type programming language or a framework. However, these methods are intended to reduce the burden on the application creator, and are intended for the convenience of the developer. In the present invention, by generating a license agreement at the same time as generating an application, it is possible to clearly present a license agreement whose operation is guaranteed to the user of the application, and to improve convenience for the user. it can.

(Second Embodiment)
In the first embodiment, it is assumed that the processing by the second functional block used when generating the application is executed on the agent 20. However, if the agent 20 executes all of the processing by the second functional block, the high speed may be lost.

  Therefore, the environment in which the processing by the second functional block is actually executed may be outsourced to an external device such as an external server instead of on the agent 20. However, by entrusting execution of processing by the second functional block to an external server, data handled in the agent 20 may be transmitted to the outside. For this reason, a security problem and / or a privacy problem may occur.

  In general, a technique for moving an operation program on a terminal from a terminal with few resources at the execution location of the program to a nearby proxy terminal with many resources is called Cyber foraging (see Non-Patent Documents 1 and 2). Yes. However, with these technologies, the entire program is transferred from the terminal to the cloud, and processing cannot be transferred only to a part of the processing.

On the other hand, Amazon silk (registered trademark) is a web browser developed is possible to change the execution location to the cloud in the functional units for drawing acceleration. However, there is a criticism that privacy and security are not protected because we focus only on the optimal speedup.

  As described above, there is no existing mechanism that can achieve both high speed and safety in the balance desired by the user. In the second embodiment, an information generation apparatus capable of generating an application that can be executed while the user of the agent 20 selects high speed and safety will be described.

  FIG. 9 is a block diagram illustrating a functional configuration of the information generation apparatus 30 according to the second embodiment. The information generation apparatus 30 illustrated in FIG. 9 includes a functional block registration / management unit 11, an operation / display unit 31, and an arithmetic processing unit 13.

    The operation / display unit 31 is an interface with the outside, and receives operations from an application developer and a system administrator. Further, the operation / display unit 31 displays the function blocks, applications, usage agreements, and the like registered in the function block registration / management unit 11.

  The developer selects a functional block displayed on the operation / display unit 31 and connects the functional blocks selected on the operation / display unit 31.

  Further, the operation / display unit 12 registers the function block approved by the system administrator or a trusted third party in the function block registration / management unit 11. At this time, if there is a second functional block that executes processing having transmission processing to the outside as a function, the system administrator or a trusted third party adds a flag to the second functional block. . This flag indicates that the processing by the second functional block includes transmission processing to another location, and all the second functional blocks after the second functional block to which the flag is added are located at the other location. Is executed.

An example of functional block registration processing by the operation / display unit 31 will be specifically described. The operation / display unit 31 displays the source code of the first functional block. The system administrator and a trusted third party are obtained by the first functional block through visual inspection of the source code displayed on the operation / display unit 31 or confirmation through execution of the first functional block. It is determined in advance whether or not the data type matches the type of data used in the application. If there is a match, the system administrator and the trusted third party approve the first functional block. The operation / display unit 31 causes the functional block registration / management unit 11 to register the approved first functional block.
The operation / display unit 31 displays the source code of the second functional block. The system administrator and a trusted third party refer to the source code displayed on the operation / display unit 31 and determine in advance whether or not the processing by the second functional block has a transmission processing to the outside as a function. To do. When having the transmission process as a function, the system administrator and a trusted third party add a flag to the second functional block. Further, the system administrator and a trusted third party refer to the source code displayed on the operation / display unit 31 to determine whether or not the processing content of the second functional block is associated with the usage permission message. Judge in advance. If so, the system administrator and the trusted third party approve the second functional block. The operation / display unit 31 causes the function block registration / management unit 11 to register the approved second function block.

  The arithmetic processing unit 13 implements an application generation unit 131, a use permission sentence generation unit 132, and a signature addition unit 133.

  When the arrangement of the functional blocks is determined on the operation / display unit 31 and an arbitrary output is obtained, the developer gives an application generation instruction to the application generation unit 131 via the operation / display unit 31. When an application generation instruction is given from the developer, the application generation unit 131 considers each function block as a node and a connection portion between each function block as a directed edge, and starts a topological sort. If the graph is an acyclic directed graph as a result of the topological sort, the application generation unit 131 confirms that the input format between the functional blocks constituting the graph determined as the acyclic directed graph by the topological sort matches the output format. Confirm whether or not. If they match, the application generation unit 131 connects the functional blocks by passing a return value as an argument between the functional blocks. Here, the first functional block has an output format, and the second functional block has an output format and an input format. Further, when a flag is attached to the second function block, the second function block is connected including the flag. Note that the second functional block may have a plurality of input formats and a plurality of output formats.

  The agent 20 receives the application generated by the information generating device 30 and the usage agreement. When the agent 20 receives a request for compiling the application from the user, the agent 20 first confirms the signature attached to the application and the license agreement. As a result, the agent 20 confirms that the application and the usage agreement have not been tampered with. When the agent 20 confirms that the application and the usage agreement have not been tampered with, the agent 20 presents the usage agreement to the user. When the user grants permission to the contents of the license agreement, the user compiles the application.

  Further, the agent 20 determines whether or not the application includes a functional block with a flag when compiling the application. When the functional block with the flag is included, the agent 20 informs the user that the position of the functional block with the flag and the position of the other second functional block included in the application are interchangeable. indicate.

  Based on the display of the agent 20, the user determines by himself whether to ensure high speed or safety, and replaces the position of the functional block.

  10 and 11 are diagrams illustrating a configuration example of a functional block of an application. When the application requested to be compiled has the configuration shown in FIG. 10, the agent 20 determines that a flag is attached to the function block B1 that transmits data from the agent 20 to the external server. The agent 20 displays to the user that the position of the functional block B1 and the position of the second functional block B2 that performs the first mesh transformation can be changed.

  The user moves the position of the functional block depending on whether the terminal needs high speed or safety. That is, when safety is more important than high speed, the user moves the functional block B2 before the functional block B1, as shown in FIG. In the application shown in FIG. 11, before transmitting data to an external server, latitude data and longitude data are converted into a mesh code in the agent 20. For this reason, since the amount of data transmitted to the external server is reduced, the safety is increased. On the other hand, since it is necessary to convert to a mesh code in the agent 20, there are fewer free resources than when the conversion process is executed on the server, and the high speed may be impaired.

  When high speed is more important than safety, the user compiles the application while maintaining the configuration shown in FIG. In the application shown in FIG. 10, since the latitude data and the longitude data are transmitted to the external server without performing any rounding process, safety is low. On the other hand, since there is no need to convert to a mesh code within the agent 20, free resources increase and high speed can be maintained.

  As described above, in the second embodiment, the functional block registration / management unit 11 registers a functional block with a flag indicating that the function and / or the object is executed elsewhere. The agent 20 allows the user to freely determine the execution position of the functional block constituting the application when a flag is attached to the functional block included in the application. As a result, the user can cause the external server to execute functions subsequent to functions with less security risk. In addition, since the user can select a function block that is variably moved, it is possible to realize program execution with an optimal apportionment by each individual rather than a balance between uniform safety and high speed. . In addition, the user can execute an application with an external server in consideration of whether to focus on high speed or safety.

  Therefore, according to the information generation device 30 according to the second embodiment, the user can select the high speed and safety, and generate an application that can be executed in cooperation with the external device. Can do.

  In the second embodiment, the case where the user changes the position of the functional block with reference to the display of the agent 20 has been described as an example. However, it is not limited to this. For example, the security privacy policy may be set in advance in the agent 20 by the user. When the application includes a functional block with a flag, the agent 20 refers to the set security privacy policy and changes the execution position of the functional block.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.

  The apparatus of the present invention can also be realized by a computer and a program, and can be recorded on a recording medium or provided through a network.
