[Technical field]

[0001] The present invention relates to an information processing device, an information processing system, an information processing method, and a program. [Background technology]

[0002] With the introduction of 5G using the latest technology, it is becoming possible for the network to provide functions such as large capacity, low latency, and multiple connections. As a result, services that are more dependent on communication infrastructure are becoming more widespread. In addition, it is thought that issues in terms of safety and security, division of responsibility, and issues regarding guarantees and compensation will arise. For example, in the case of drones that are flown using wireless technology such as 5G and the associated communication network, if a problem occurs due to the communication network, there may be a demand to separate end-to-end between the provider of the drone-based transportation service, the communication carrier that provided the network, and the equipment manufacturer that manufactured the drone, regarding where the problem occurred and who is responsible for guarantees and compensation.

[0003] Currently, log information for communication infrastructure such as communication devices and communication paths is stored and managed on servers managed by telecommunications carriers using technologies such as SNMP, Telemetry, packet capture, and NetFlow.

[0004] Meanwhile, Patent Document 1 discloses a method for tracking information about devices in a network, the method including: receiving, at a first gateway, a plurality of communications each including information indicating a state of one of a plurality of devices, grouping, at the first gateway, information from two or more of the plurality of communications into a single transaction record including a hash of a previous transaction record related to the network, and sending the single transaction record from the first gateway to a server.

The acquisition unit 11 is one form of the "acquisition means" recited in the claims, and the generation unit 12 is one form of the "generation means" recited in the claims.

[0020] In this exemplary embodiment, the communication infrastructure refers to communication devices and communication paths owned by a communication carrier that constitutes the communication network. There are one or more communication carriers that constitute the communication network, and each communication carrier owns its own communication infrastructure. End users, such as a provider of a service using the communication network, a user of the service, an administrator of one or more communication businesses, and a supervisor of the communication business or service, are connected to each other via the communication network. Communication devices in the communication network are also called nodes. A communication path is a path that connects an end user's terminal and a node, and a node and a node. A terminal of one end user can communicate with a terminal of another end user via a communication device (node) and a communication path owned by one or more communication carriers. In this exemplary embodiment, a service using a communication network is, for example, a delivery service of goods using a drone. In this case, a service provider can control a drone via a communication network to deliver goods. A user of the service can use the delivery service of goods using a drone. In this case, each end user is a member of the parties involved in the provision of the service, and is also called a stakeholder.

[0021] In this exemplary embodiment, the log information is information relating to transactions between a user of a service and a provider of that service (contents of the service, conditions, etc.) and information relating to the communications used to provide the service. The log information includes information relating to the communications equipment and communications paths owned by the communications carrier. The log information may also include the time at which the communications service was used. Hereinafter, information relating to the communications equipment is also referred to as communications equipment information.

As shown in FIG. 5, the information processing device 3 includes a first acquisition unit 31, a second acquisition unit 32, and a comparison unit 33. The first acquisition unit 31 acquires log information of one or more communication infrastructures used to provide a service identified by a certain service ID from transaction data registered in a blockchain, which is transaction data identified by a certain service ID and is updated using a predetermined consensus algorithm. The second acquisition unit 32 acquires service level agreement information related to a service identified by a certain service ID. The comparison unit 33 compares the log information with the service level agreement information and outputs a comparison result. The first acquisition unit 31 is an embodiment of the "first acquisition means" described in the claims. The second acquisition unit 32 is an embodiment of the "second acquisition means" described in the claims. The comparison unit 33 is an embodiment of the "comparison means" described in the claims.

[0035] In this exemplary embodiment, the service ID is a code linked to the transaction data described above. Therefore, the contents of the transaction data linked thereto can be obtained from the service ID. In addition, in this exemplary embodiment, the service level agreement information is information on the quality of the communication infrastructure used to provide the service, which is agreed upon between the service provider and one or more communication carriers. Specifically, the service level agreement information may include communication path requirements (e.g., communication capacity, communication speed, etc. of the communication path) and communication device requirements (e.g., connection time, transfer speed, etc. of the communication device). In addition, the service level agreement information may include communication requirements agreed upon between the service provider and the service user, or operation requirements of the communication infrastructure defined by some standard. In this exemplary embodiment, the transaction data includes the service level agreement information.

[0047] (Communication Network Configuration) As shown in FIG. 8, in this exemplary embodiment, the terminals used by end users are a service provider terminal e1, a service user terminal e2, an administrator terminal e3, a communication infrastructure A operator terminal e4 (hereinafter also referred to as "communication operator A"), and a communication infrastructure B operator terminal e5 (hereinafter also referred to as "communication operator B"). The service provider and the service user are end users who have concluded a service contract. As an example, the service provider uses a communication infrastructure A owned by communication operator A and a communication infrastructure B owned by communication operator B to provide a service. The administrator is a member who initiates a blockchain that records information according to this exemplary embodiment and participates in the blockchain.

[0048] The terminals are connected to each other via a plurality of nodes n1 to n6. The communication path NA is a path connecting the terminal e1 of the service provider and the node n1. The communication path NB is a path connecting the terminal e2 of the service user and the node n2. The terminals may be connected via a peer network PN.

Below, we will explain the configuration and procedure for an end user to generate transaction data and register it in the blockchain in such a network environment.

[0049] (Configuration of service provider terminal 100) Fig. 9 is a block diagram showing an example of the configuration of a terminal 100 (an example of a terminal e1) of a service provider in this exemplary embodiment. As shown in Fig. 9, the terminal 100 includes a control unit 110, a communication unit 120, a memory 130, and a storage unit 140. The control unit 110 controls the entire terminal 100.

The recording unit 111 records a service ID for identifying a service, a service time, communication-related information, etc. in the storage unit 140. The service ID, time information, communication-related information, etc. are acquired by the acquisition unit 112 via the communication unit 120. The time information is time information such as a service start time and a service end time. The communication-related information, etc. is communication device information and communication path information, as described above. The time information and communication-related information, etc. are log information of one or more communication infrastructures used to provide the service.

[0051] The transaction data generating unit 113 generates transaction data from the information recorded in the storage unit 140. The transaction data generating unit 113 associates the transaction data 141 with a service ID that identifies a service. Specifically, in this exemplary embodiment, as shown in FIG. 9, the transaction data 141 includes a service ID 1411, time information 1412, communication device information 1413, and communication path information 1414. The communication device information is, for example, information indicating the state (status) of the communication device. The information indicating the state of the communication device is, for example, information such as a state of normal operation or abnormal operation, or information such as a time required to connect the communication device, and a data transfer rate. The communication path information is, for example, information indicating the state (status) of the communication path. The information indicating the state of the communication path is, for example, information indicating the connection state, communication capacity, or communication speed of the communication path. Note that the time needs to be synchronized on the network, so for example, NTP (Network Time Protocol) is used.

[0052] Furthermore, the transaction data generation unit 113 may include, as log information, in the transaction data 141, at least one of a communication path ID for identifying a communication path used in providing the service and a communication device ID for identifying a communication device used in providing the service. Furthermore, the transaction data 141 may include all of the communication device information, the communication path information, the communication device ID, and the communication path ID.

[0053] (Configuration of Administrator Terminal 200) Fig. 10 is a block diagram showing an example of the configuration of the administrator's terminal 200 (an example of terminal e3) in this exemplary embodiment. As shown in Fig. 10, the terminal 200 includes a control unit 210, a communication unit 220, a memory 230, and a storage unit 240. The control unit 210 controls the entire terminal 200. The communication unit 220 communicates with external devices. The memory 230 records programs and various data used by the control unit 210. The storage unit 240 records block 1 (BL1), block 2 (BL2), block 3 (BL3), etc., which are block data constituting the blockchain.

[0054] The control unit 210 will be described in detail. The control unit 210 includes a recording unit 211, an acquisition unit 212, a block generation unit 213, and a block registration unit 214. The recording unit 211 records the transaction data acquired by the acquisition unit 212 via the communication unit 220 in the storage unit 240. The block generation unit 213 generates blocks to be registered in the blockchain from the information recorded in the storage unit 240. The data recorded in the blocks will be described later. The block registration unit 214 registers blocks that have been approved by other end users based on a predetermined consensus algorithm, Blockchain The block registration unit 214 is an embodiment of the "registration means" described in the claims. In this exemplary embodiment, the predetermined consensus algorithm is described using PoW (Proof of Work). However, the consensus algorithm is not limited to PoW, and PoS (Proof of Stake), PoI (Proof of Importance), PoH (Proof of Human-work), etc. may be used.

[0055] Although the administrator's terminal 200 has been described as an example, each end user participating in the blockchain has a terminal with a similar configuration, which records the blockchain. In other words, the terminal e4 of the telecommunications carrier A and the terminal e5 of the telecommunications carrier B also have the same configuration.

[0056] Next, a description will be given of data included in a block generated by the block generation unit 213. Fig. 11 is a diagram showing an example of data included in a block generated by the block generation unit 213. The blocks are generated in the order in which the data is approved. Blockchain In Fig. 11, block BL3 is the newest data. The data contained in block BL3 includes a block header BL31 and transaction data BL32.

[0057] The block header BL31 includes a hash value BL311 of the block header BL21 of the previous block (block BL2 in FIG. 11), a hash value BL312 of the transaction data, and a nonce value BL313. A hash value is a bit string obtained using a hash function. A hash function is a function that generates a fixed-length bit string from a bit string of any length. A nonce value is a random fixed-length bit string that satisfies certain conditions.

[0058] The transaction data BL32 includes a service ID BL321, time information BL322, first communication related information BL323, second communication related information BL324, third communication related information BL325, etc. The first communication related information BL323 includes first communication route information and first communication device information owned by a first telecommunications carrier (e.g., telecommunications carrier A). Similarly, the second communication related information BL324 includes second communication route information and second communication device information owned by a second telecommunications carrier (e.g., telecommunications carrier B), and the third communication related information BL325 includes third communication route information and third communication device information owned by a third telecommunications carrier. The following communication related information is included for the number of involved telecommunications carriers.

[0059] The data contained in block BL3 has been described above. The data contained in block BL2 and block BL1 are similar, so a description thereof will be omitted.

[0060] (The process for registering data) Next, a flow from when transaction data is generated by a service provider's terminal until it is registered in the blockchain recorded in each end user's terminal will be described. FIG. 12 is a time chart S4 showing the flow from when a block generated by a service provider's terminal is registered in the blockchain recorded in each end user's terminal. The "infrastructure A operator" in FIG. 12 means an operator that owns communication infrastructure A, and is hereinafter referred to as "communication operator A". Furthermore, the "infrastructure B operator" means an operator that owns communication infrastructure B, and is hereinafter referred to as "communication operator B".

[0061] The leftmost part of Fig. 12 shows the work performed by the terminal e1 of the service provider. First, in step S41, the terminal e1 of the service provider provides a service. Note that prior to step S41, negotiations and a contract for a service transaction are made between the service provider and the service user, but are omitted in this figure.

[0062] Next, in step S42, the terminal e1 of the service provider records the service ID and the service time. The service time includes the service start time and the service end time. Next, in step S43, the terminal e1 of the service provider transmits an inquiry to the terminal e4 of the communication carrier A and the terminal e5 of the communication carrier B involved in the provision of the service to request them to provide communication-related information.

[0063] In response to this, in step S48, terminal e4 of telecommunications carrier A provides (transmits) communication-related information A (communication-related information possessed by telecommunications carrier A) to terminal e1 of the service provider. Also, in step S51, terminal e5 of telecommunications carrier B provides (transmits) communication-related information B to terminal e1 of the service provider. In response to this, in step S44, terminal e1 of the service provider generates transaction data including communication-related information A and B. Then, in step S45, terminal e1 of the service provider transmits a request for block creation together with the transaction data to each of end user terminals e3, e4, and e5.

[0064] In response, the end user terminals e3, e4, and e5 search for a nonce value that satisfies the predetermined condition. In this exemplary embodiment, it is assumed that the administrator terminal e3 is the first to find a nonce value that satisfies the predetermined condition. Then, in step S46, the administrator terminal e3 generates a block including the transaction data sent by the service provider terminal e1. Furthermore, the administrator terminal e3 transmits the generated block to each end user terminal e4, e5 and requests approval. In steps S49 and S52, each end user terminal e4, e5 confirms that the nonce value is correct and returns approval to the administrator terminal e3.

[0065] In response to this, the administrator terminal e3 registers the block in the blockchain in step S47. Similarly, the terminals e4 and e5 of the telecommunications carriers A and B register the block generated by the administrator terminal e3 in the blockchain recorded in their respective storage units in steps S50 and S53, respectively.

[0066] In the above explanation, an example was described in which each end user's terminal searches for a nonce value that satisfies a predetermined condition. However, a terminal of an administrator of some organization may search for a nonce value on behalf of the end users.

[0067] Through the above process, the block generated by the administrator terminal e3 is registered in the blockchain of the end user terminals e4 and e5. As described above, the configuration shown in the exemplary embodiment 2 allows end users to share transaction data registered in the blockchain.

[0068] Therefore, the configuration of this exemplary embodiment 2 has the effect of providing a technology that enables parties involved in the provision of a service to share information regarding the communication infrastructure used in the provision of the service.

[0069] Exemplary embodiment 3 Next, a third exemplary embodiment of the present invention will be described with reference to the drawings. Note that the description of components having the same functions as those described in the first and second exemplary embodiments will be omitted as appropriate. In the second exemplary embodiment, an embodiment in which a service provider terminal generates transaction data has been described. In the third exemplary embodiment, an embodiment in which an administrator terminal generates transaction data will be described.

[0070] (Configuration of service provider terminal 300) Fig. 13 is a block diagram showing an example of the configuration of a terminal 300 (an example of a terminal e1) of a service provider in this exemplary embodiment. As shown in Fig. 13, the terminal 300 includes a control unit 310, a communication unit 320, a memory 330, and a storage unit 340. The control unit 310 controls the entire terminal 300. The communication unit 320 communicates with external devices. The memory 330 records programs and various data used by the control unit 310. The storage unit 340 records various information and generated log information.

[0071] The control unit 310 will be described in detail. The control unit 310 includes a recording unit 311, an acquisition unit 312, and a log information generation unit 313. The recording unit 311 records the service ID, time information, communication related information, etc. in the storage unit 340. The service ID, time information, communication related information, etc. are acquired by the acquisition unit 312 via the communication unit 320. The time information and communication related information, etc. are as described in the exemplary embodiment 2. The log information generation unit 313 generates log information from the information recorded in the storage unit 340. As shown in FIG. 13, in this exemplary embodiment, the log information 342 includes time information 3421, communication device information 3422, and communication path information 3423. The log information 342 is linked to the service ID 341.

[0072] (Configuration of Administrator Terminal 400) FIG. 14 is a block diagram showing an example of the configuration of the administrator's terminal 400 (an example of the terminal e3) in this exemplary embodiment. As shown in FIG. 14, the terminal 400 includes a control unit 410, a communication unit 420, a memory 430, and a storage unit 440. The control unit 410 controls the entire terminal 400. The communication unit 420 communicates with external devices. The memory 430 records programs and various data used by the control unit 410. The storage unit 440 records block 1 (BL1), block 2 (BL2), block 3 (BL3), etc., which are block data constituting the blockchain. The data recorded in block 1 (BL1) and the like is the same as that described in exemplary embodiment 2, so the description thereof will be omitted.

[0073] The control unit 410 will be described in detail. The control unit 410 includes a recording unit 411, an acquiring unit 412, a transaction data generating unit 413, a block generating unit 414, and a block registering unit 415. Among these, the recording unit 411, the acquiring unit 412, the block generating unit 414, and the block registering unit 415 are similar to the recording unit 211, the acquiring unit 212, the block generating unit 213, and the block registering unit 214 described in the second exemplary embodiment, and therefore descriptions thereof will be omitted.

[0074] The transaction data generation unit 413 generates transaction data from the information recorded in the storage unit 440. Specifically, the transaction data is, for example, a service ID and log information associated with the service ID.

[0075] (The process for registering data) Next, we will explain the flow from when transaction data is generated by the administrator's terminal e3 to when it is registered in the blockchain recorded in the end user's terminals e3, e4, and e5. Figure 15 is a time chart S6 showing the flow from when the block generated by the administrator's terminal e3 is registered in the blockchain of the end user's terminals e3, e4, and e5.

[0076] As shown in Fig. 15, first, in step S61, the service provider terminal e1 provides a service. Next, in step S62, the service provider terminal e1 records a service ID and a service time. The service time includes a service start time and a service end time. Next, in step S63, the service provider terminal e1 transmits an inquiry to the terminals e4 and e5 of the communication carriers involved in the provision of the service to request them to provide communication-related information.

[0077] In response to this, in step S70, terminal e4 of telecommunications carrier A provides (transmits) communication-related information A to terminal e1 of the service provider. Also, in step S73, terminal e5 of telecommunications carrier B provides (transmits) communication-related information B to terminal e1 of the service provider. In response to this, in step S64, terminal e1 of the service provider generates log information including the communication-related information A and B. Then, in step S65, terminal e1 of the service provider transmits a request for creating transaction data to terminal e3 of the administrator, together with the log information.

[0078] In response to this, the administrator terminal e3 generates transaction data including log information in step S66. Next, in step S67, the administrator terminal e3 transmits a block creation request together with the transaction data to terminals e4 and e5 of the communication carriers A and B.

[0079] In response, terminals e4 and e5 of telecommunications carriers A and B search for a nonce value that satisfies the predetermined condition. In this exemplary embodiment, it is assumed that the administrator terminal e3 is the first to discover a nonce value that satisfies the predetermined condition. Then, in step S68, the administrator terminal e3 generates a block including transaction data that it has generated. Furthermore, the administrator terminal e3 transmits the generated block to terminals e4 and e5 of telecommunications carriers A and B and requests approval. In steps S71 and S74, the terminals e4 and e5 of telecommunications carriers A and B respectively confirm that the nonce value is correct and return approval to the administrator terminal e3.

[0080] In response to this, the administrator terminal e3 registers the block in the blockchain in step S69. Similarly, the terminals e4 and e5 of the telecommunications carriers A and B register the block generated by the administrator terminal e3 in the blockchain recorded in their own memory units in steps S72 and S75, respectively.

[0081] Through the above process, a block including transaction data generated by the administrator terminal e3 is registered in the blockchain recorded in the end user terminals e3, e4, and e5. As described above, the configuration shown in the exemplary embodiment 3 allows the end user terminals e3, e4, and e5 to share the transaction data registered in the blockchain.

[0082] Therefore, the configuration of this exemplary embodiment 3 has the effect of providing a technology that enables parties involved in the provision of a service to share information regarding the communication infrastructure used in the provision of the service.

[0083] Exemplary embodiment 4 Next, a fourth exemplary embodiment of the present invention will be described with reference to the drawings. Note that the description of components having the same functions as those described in the first to third exemplary embodiments will be omitted as appropriate. In the fourth exemplary embodiment, an embodiment will be described in which recorded log information is compared with service level agreement information and the comparison result is output.

[0084] FIG. 16 is a diagram showing an example of a communication network in this exemplary embodiment. The communication network shown in FIG. 16 is different from the communication network shown in FIG. 8 in that it includes a service database e6 communicatively connected to each terminal, and a node n7 connected to the service database e6. In the service database e6, as an example, transaction data stored in the blockchain is stored together with a service ID associated therewith. In addition, in the service database e6, as an example, service level agreement information may be stored. In this case, the service level agreement information is associated with the service ID and managed (stored). Therefore, the service level agreement information differs for each service. In the service database e6, communication-related information may be stored together with a specific code linked to the communication-related information.

[0085] FIG. 17 is a block diagram showing a configuration example of the manager's terminal 500 (an example of the terminal e3) in this exemplary embodiment. As shown in FIG. 17, the terminal 500 includes a control unit 510, a communication unit 520, a memory 530, a display unit 540, and a storage unit 550. The control unit 510 controls the entire terminal 500. The communication unit 520 communicates with external devices. The memory 530 records programs and various data used by the control unit 510. The display unit 540 displays, for example, a result of comparison by a comparison unit 516 described later. The storage unit 550 records transaction data 551 generated by a transaction data generation unit 513 described later, service level agreement information 552 acquired by an acquisition unit 512 described later via the communication unit 520, and the like.

[0086] The control unit 510 will be described in detail. The control unit 510 includes a recording unit 511, an acquiring unit 512, a transaction data generating unit 513, a block generating unit 514, a block registering unit 515, and a comparing unit 516. Among them, the recording unit 511, the transaction data generating unit 513, the block generating unit 514, and the block registering unit 515 are similar to the recording unit 411, the transaction data generating unit 413, the block generating unit 414, and the block registering unit 415 described in the exemplary embodiment 3. The acquiring unit 512 acquires transaction data 551 via the communicating unit 520. In addition, the acquiring unit 512 acquires service level agreement information 552 related to the service via the communicating unit 520. The service level agreement information is acquired from the service database e6, as an example. In addition, the comparing unit 516 compares the log information included in the transaction data 551 with the service level agreement information 552, and outputs the comparison result. This comparison result is displayed on the display unit 540. The acquiring unit 512 is an embodiment of the "second acquiring means" set forth in the claims. The comparing unit 516 is an embodiment of the "comparing means" set forth in the claims.

[0087] In this exemplary embodiment, the configuration of the terminal has been described by taking the administrator's terminal 500 as an example, but the acquisition unit 512 and comparison unit 516 can also be provided in each end user's terminal.

[0088] Fig. 18 is a diagram showing an example of data included in transaction data 551 and service level agreement information 552. As shown in Fig. 18, transaction data 600 (an example of transaction data 551) includes a service ID 610, time information 620, first communication path information and first communication device information (collectively referred to as first communication related information) 630, second communication path information and second communication device information (collectively referred to as second communication related information) 640, third communication path information and third communication device information (collectively referred to as third communication related information) 650, etc. Each piece of communication related information is communication related information recorded and owned by a business operator involved in the provision of the service.

[0089] Moreover, the service level agreement information 700 (an example of the service level agreement information 552) includes a first communication path requirement and a first communication equipment requirement (collectively referred to as the first communication-related requirement) 710, a second communication path requirement and a second communication equipment requirement (collectively referred to as the second communication-related requirement) 720, a third communication path requirement and a third communication equipment requirement (collectively referred to as the third communication-related requirement) 730, etc. Each communication-related requirement is a communication quality requirement presented or guaranteed by a business operator involved in the provision of the service. The service level agreement information 700 may also include a service ID.

[0090] FIG. 19 is an example of a screen displaying the results of the comparison performed by the comparison unit 516 on the display unit 540. A first comparison result 810, a second comparison result 820, and a third comparison result 830 are displayed on a screen 800 displaying the comparison results. This screen 800 shows a display example in which a service is provided using communication infrastructures owned by three communication carriers. The first comparison result 810 is a comparison result for the communication infrastructure owned by the first communication carrier. Similarly, the second comparison result 820 is a comparison result for the communication infrastructure owned by the second communication carrier. The third comparison result 830 is a comparison result for the communication infrastructure owned by the third communication carrier.

[0091] 19, it is displayed that the communication performed using the communication infrastructure of the first telecommunications carrier satisfies the communication path requirements (e.g., communication path communication capacity, communication speed, etc.) but does not satisfy the communication device requirements (e.g., communication device connection time, transfer speed, etc.). It is also displayed that the communication infrastructures of the second telecommunications carrier and the third telecommunications carrier both satisfy the requirements.

[0092] Next, a description will be given of the flow of a comparison and output method executed by the administrator's terminal 500 to compare the log information with the service level agreement information and output the comparison result. A comparison between the log information and the service level agreement information is required, for example, when a defect occurs in the service provided by the service provider and the defect may be due to a defect in the communication infrastructure owned by the communication carrier.

[0093] Fig. 20 is a flowchart showing the flow S8 of the comparison and output method. As shown in Fig. 20, first, in step S81, the control unit 510 judges whether or not the service ID of the service in which the defect has occurred has been acquired. If it is judged that the service ID has been acquired (step S81: Y), the process proceeds to step S83. On the other hand, if it is judged that the service ID has not been acquired (step S81: N), the process proceeds to step S82. In step S82, the acquisition unit 512 acquires the service ID of the service recorded in the blockchain via the communication unit 520. Then, the flow proceeds to step S83.

[0094] In step S83, the acquisition unit 512 accesses the service database e6 to acquire log information associated with the service ID. The acquired log information includes communication-related information. Next, in step S84, the comparison unit 516 compares the service level agreement information with the acquired log information. If the service level agreement information is associated with the service ID and recorded in the service database e6, it can be acquired from the service database e6. Alternatively, if the service level agreement information is recorded in the transaction data of the blockchain, it may be acquired from the transaction data.

[0095] Next, in step S85, the comparison unit 516 outputs the communication infrastructures that do not satisfy the service level agreement information. The display unit 540 displays the information output from the comparison unit 516. For example, the display unit 540 displays the comparison results of all the communication infrastructures involved, as shown in Fig. 19. Alternatively, the comparison unit 516 may output only the communication infrastructures that do not satisfy the service level agreement information. Note that the output method and the method of displaying the output information are not limited to the above examples.

[0096] As described above, when the log information is associated with the service ID and stored in the service database e6, Blockchain In addition, when the service level agreement information is linked to the service ID and stored in the service database e6, it is not necessary to record the service level agreement information in the blockchain of the end user's terminal, and the amount of data to be recorded can be further reduced.

[0097] As described above, with the configuration according to the fourth exemplary embodiment, the comparison unit 516 can compare the log information with the service level agreement information and output the comparison result. Each end user can check the communication infrastructure that has a defect from the comparison result.

[0098] Therefore, according to the configuration of exemplary embodiment 4, in addition to the effect that end users can share transaction data registered in the blockchain, if there is a problem with the service, the location of the problem in the communication infrastructure is displayed so that the end user can check it.
