Description

  The present invention relates to a seismic observation system, a seismic observation program, and a seismic observation method for performing seismic observation by forming a network using, for example, a mobile phone.

  Conventionally, for example, an earthquake observation system that can collect earthquake waveform data from observation terminals installed in various places has been proposed (see Patent Document 1). That is, in this earthquake observation system, when an earthquake occurs, the observation terminal acquires waveform data and acceleration data of the earthquake. In this system, according to an instruction from a user or when a predetermined time is reached, the seismic waveform data collection device requests the observation terminal to transmit acceleration data. In response to this request, the observation terminal transmits acceleration data to the seismic waveform data collection device.

  Then, the seismic waveform data collection device determines whether or not the acceleration data satisfies a predetermined collection condition. If the acceleration data determines that the acceleration data satisfies the collection condition, the seismic waveform data collection device requests the observation waveform data from the observation terminal. In response to this request, the observation terminal transmits the waveform data to the seismic waveform data collection device. The earthquake waveform data collection device receives and stores the waveform data.

  However, in the technique described in Patent Document 1 described above, when the seismic waveform data collection device fails or communication becomes impossible, there is a problem that it becomes impossible to collect seismic waveform data. In addition, a system has been proposed in which an earthquake observation network is configured using a mobile terminal, and earthquake determination, warning, communication, and the like are performed within the network (for example, Patent Document 2).

(Operation of the earthquake observation system)
(1) Overall operation By operating the earthquake observation system described above, the earthquake observation method of the present invention can be implemented. FIG. 5 is a flowchart showing the operation of the earthquake observation system according to the present embodiment. 6-9 is explanatory drawing regarding an earthquake detection.

  First, when an application is activated on the user terminal (S101), attitude information is acquired (S102). Specifically, the observation control unit 145a monitors the posture of the smartphone 1 based on detection results by various sensors (gyro sensor, direction sensor, acceleration sensor, etc.) 16. Then, by the loop processing (“N” in S103), the smartphone 1 is in a standby state until it enters a stationary state where it does not move and the tilt does not change, such as on a desk or in a luggage.

  Then, when it is detected in step S103 that the stationary state of the smartphone 1 has continued for a certain period of time ("Y" in S103), the observation of the earthquake is started and the fact is notified to the observation server 3 (S104). . Upon receiving this observation start notification, the observation server 3 adds the smartphone 1 that has transmitted the notification to the monitoring target, and starts collecting observation information from the smartphone 1 (S201). When the observation is started, the position information acquisition unit 144 acquires position information related to the current position / altitude of the smartphone 1 on the smartphone 1 side, and transmits the position information to the observation server 3 side (S105). In response to the transmission of the position information, the observation server 3 side registers the current position of the smartphone 1 in the user terminal data 35b.

  Next, when the earthquake observation is started, the smartphone 1 is in a standby state until a vibration of a predetermined value or more is detected (“N” in S106). Thereafter, when vibration of a predetermined value or more is detected (“Y” in S106), the detected vibration waveform and time, its own identifier and current position information are transmitted to the observation server 3 as a vibration detection report.

  The observation server 3 collects and analyzes vibration detection reports from each terminal, altitude indicator 41, and underground detector 42 (S203 and S204). In this data collection and analysis, as shown in FIG. 7, a virtual grid (for example, 250 m square) is defined on the coordinates, and a group of buildings B1 existing in each area G1 defined by the grid are collectively collected. You may make it carry out. In this case, the analysis result of each building included therein is averaged for each area G1 and displayed or disclosed for each area G1. Accordingly, the building from which the vibration detection report is acquired can be published as a vibration analysis of the entire area without individually specifying the building, and privacy related to the building can be protected.

  Further, in analyzing the vibration detection report, the ratio of the detectors that made the vibration detection report among the smartphones 1 and the altitude alarm devices 41 to be monitored was calculated, and a certain number of vibration detection reports were made. In this case, it is determined that an earthquake has occurred (“Y” in S205). Upon the occurrence of this earthquake, the observation server 3 transmits information relating to the earthquake identified by analysis as earthquake information to each smartphone 1 (S207) and records the earthquake information (S208). Upon receiving the earthquake information, the smartphone 1 outputs an alarm sound or image to notify the user (S109).

  In addition, the recording of this earthquake information may use a so-called distributed ledger network that records information on a network in a distributed manner as will be described in an embodiment described later. In this case, through the distributed ledger network, The recorded earthquake information can also be released. In disclosing this earthquake information, it is preferable that the analysis results regarding each building as described above are averaged for each area so that individual buildings cannot be specified. In addition, for this earthquake information, the analysis results such as vibration, proof strength, strength, etc. regarding the structural material of the building subject to analysis are filtered according to the type of member, product, use location, aging, etc. It can be aggregated by processing, grouping processing, and sorting processing to be output, displayed, and published.

  In addition, the protocol related to the collection, data storage, browsing, and disclosure of earthquake information uses generalized public technologies such as libraries and APIs based on open source, so that specific persons cannot be managed and operated exclusively. It is preferable to ensure the publicity and public interest of information.

  On the other hand, if the number of detectors that have reported vibration detection in step S205 is less than a certain number, an instruction to measure the observation as it is is transmitted to each terminal as if an earthquake has not occurred (S206). Upon receiving the observation continuation instruction, the smartphone 1 notifies the user by displaying a message indicating that an earthquake has not occurred, etc., and then returns to step S102 to continue the processing from step S102 onward. And repeat.

(2) Vibration analysis Here, the earthquake analysis in step S204 mentioned above is demonstrated. 6-8 is explanatory drawing which shows the outline | summary of the earthquake detection which concerns on this embodiment, and FIG. 8 shows the method of simplifying the structure of a building at the time of calculating the vibration propagation to the height direction of a building. It is explanatory drawing.

  As shown in FIGS. 6A and 6B, when an earthquake occurs and the seismic wave EqW propagates through the ground, the altitude indicator 41 and the underground detector 42 provided in each smartphone 1 or the structure 5. Etc. sequentially detect vibrations. Vibration detection reports from each smartphone 1, altitude indicator 41, and underground detector 42 are collected by the observation server 3, and the epicenter and the magnitude of the earthquake that occurred are estimated from the time difference of the vibration detection and the attenuation of the amplitude. To do.

  At this time, the propagation of vibration in the height direction in the structure 5 is calculated by a method that simplifies the structure of the building as shown in FIG. In this method, the structure of the joint portion 53 to which the columns 51a and 51b and the beams 52a and 52b constituting the structure 5 are joined is simplified. That is, assuming that the joint 53 is a sphere 530 having a constant radius and bending strength, the structural members such as columns and beams constituting the structure 5 are all formed of a single member, and have a predetermined axial force and It replaces with the columns 511 and 512 and the beams 521 and 522 having the bending strength, and the transmission of stress and the transmission of the bending stress are calculated on the assumption that these structural materials are firmly attached to the surface of the joint sphere 530. In addition, the analysis results such as vibrations, proof stress, strength, etc. related to building structural materials are aggregated by various filtering processes, grouping processes, sorting processes, etc. Can be output, displayed and published.

(3) Correlation calculation As described above, big data is constructed by accumulating vibration detection reports from a large number of smartphones 1, altitude alarm devices 41, and underground detectors 42 in the observation data 35c, and the correlation calculation unit 38 Learn the correlation between the vibration amplitude detected by each vibration detection means, the distribution of the time of occurrence, the location of the earthquake and the magnitude of the earthquake, and make it possible to predict the earthquake source and magnitude by using the vibration detection report from some terminals. .

  More specifically, in this embodiment, the correlation calculation unit 38 acquires the vibration waveform, amplitude, time, and duration detected by each detector, and hierarchically extracts the feature points in the acquired image. A plurality of samples are extracted, and the correlation with the epicenter and the magnitude of the earthquake is learned by the hierarchical combination pattern of the extracted feature points.

  An outline of the recognition processing by the correlation calculation unit 38 is shown in FIG. As shown in the figure, the correlation calculation unit 38 is a multi-class discriminator, and a large number of earthquake occurrence cases such as waveforms, amplitudes, and times due to past occurrence earthquakes are set, and specific features are selected from a plurality of earthquake occurrence cases. An earthquake is detected from an amplitude detection report including a point (here, the smartphone 1 and the detectors 41 and 42). The correlation calculation unit 38 includes an input unit (input layer) 607, a first weight coefficient 608, a hidden unit (hidden layer) 609, a second weight coefficient 610, and an output unit (output layer) 611.

  A plurality of feature vectors 602 are input to the input unit 607. The first weighting factor 608 weights the output from the input unit 607. The hidden unit 609 performs nonlinear transformation on the linear combination of the output from the input unit 607 and the first weighting factor 608. The second weighting factor 610 weights the output from the hidden unit 609. The output unit 611 calculates the identification probability of each class (for example, epicenter, seismic intensity, magnitude, etc.). Although three output units 611 are shown here, the present invention is not limited to this. The number of output units 611 is the same as the number of earthquakes that can be detected by the classifier. By increasing the number of output units 611, in addition to the epicenter, the seismic intensity, and the magnitude, for example, the occurrence time, the vibration direction (rolling, pitching), etc. To increase.

  The correlation calculation unit 38 according to the present embodiment is an example of a three-layer neural network, and the discriminator learns the first weight coefficient 608 and the second weight coefficient 610 using the error back propagation method. The correlation calculation unit 38 is not limited to a neural network, and may be a deep neural network in which a plurality of multilayer perceptrons and hidden layers are stacked. In this case, the object discriminator may learn the first weighting factor 608 and the second weighting factor 610 by deep learning (deep learning).

(Action / Effect)
According to the present embodiment described above, an earthquake observation network is configured using a large number of smartphones 1 and altitude position information is taken into account by notifying the smartphone 1 of information related to altitude from the altitude indicator 4. Analyzes the effects of earthquakes and enables highly accurate earthquake simulations.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In this embodiment, real-time information on the earthquake measured by the earthquake observation system in the first embodiment described above is used to perform earthquake resistance verification for the earthquake and real estate evaluation that reflects the verification result, and the verification and evaluation The gist is that we adopted a distributed database system to store and publish the results. FIG. 10 is a conceptual diagram showing the overall configuration of the real estate management system according to the present embodiment. 11 to 13 are explanatory diagrams relating to the block chain according to the present embodiment. In the present embodiment, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the functions and the like are the same unless otherwise specified, and the description thereof is omitted.

(Configuration of real estate management system)
As shown in FIG. 10, in the real estate management system 100 according to the present embodiment, the public key PKa and the secret based on the public key cryptosystem are used in the transaction of the rights document data that proves that the owner / occupant of the real estate property. Issue a key pair with the key SKa. The observation server 3 according to the present embodiment includes a guarantee system cooperation unit that cooperates with a distributed database mechanism called a block chain instead of or in addition to the database 35c that accumulates the observation data described above. By coordinating with this guarantee system linkage unit, earthquake observation data is stored on the distributed database 90, which is a guarantee server group, in real time and cannot be tampered with.

Further, in the real estate management system 100 according to the present embodiment, the earthquake information measured by the observation server 3 described in the first embodiment can be sequentially stored in the distributed database 90, and can be disclosed on the network through the distributed database 90. It is like that. The earthquake information stored on the distributed database 90 includes real-time earthquake data collected by the observation server 3 (earthquake source, magnitude, depth, seismic waveform measured by each seismometer, etc.), and Performs earthquake simulation around the area where the data is collected using this earthquake data, and includes earthquake resistance verification and real estate evaluation based on the simulation results.
The real estate management system 100 according to the present embodiment generates the issued public key PKa or the public address PAa. This public address PAa is used as an address indicating the assignee and assignee in the real estate transaction contract. On the other hand, the private key SKa is used for an electronic signature of a transaction that uses the public address PAa as a withdrawal source.

  The real estate transaction according to the present embodiment is performed between two nodes on the P2P (Peer-to-Peer) network 20 (here, between the users Ua and Ub), and the transaction information includes the earthquake information described above. It is broadcast to the nodes 90a to 90f in the P2P network 20 and shared. As a result, a transaction history database (block chain described later), which is a distributed database, is formed on the P2P network 20, and the transaction history of real estate transactions and earthquake measurement results are stored in real time.

  In this embodiment, the transaction history database, which is a distributed database, executes, approves, and manages a real estate transaction contract when rewriting the title document data D11 through the real estate manager side device 8. An intermediary for real estate transactions (hereinafter also referred to as “real estate agent”) generates a public address PA3 unique to the real estate property in order to mediate the transaction between the transferor and the transferee, and the rights document data D11 Relay of relocation of

  Then, using the real estate management system 100, the parties to the transaction (the transferor and the transferee) relate the rights document data D11 from the current resident Ua to the public address PA3 unique to the real estate property, and the earthquake information D12. Relocate in the attached state. At this public address, these rights document data D11 and earthquake information (or data that can refer to the earthquake information D12) D12 are temporarily received, and further transferred to a new occupant Ub via the public address PA3. Thus, a real estate property sales contract is established between the users Ua and Ub.

  As a result, the user Ub who is the assignee can receive the rights document data D11 and the earthquake information (or data that can refer to the earthquake information) D12 at his / her public address PAb, and associate it with the public address PA3. It is possible to view the received service history and use the service. The public address may be issued by the real estate manager side device 8 or the communication service provider side device 7, or may be issued by an application on the smartphone 1, or by a server of an independent service management organization or financial institution. it can.

  Here, the detailed mechanism of the electronic cryptocurrency transaction will be specifically described with reference to FIGS. FIG. 11 exemplifies the definition of a transaction (transaction) related to the mechanism of the electronic cryptographic rights document included in the rights document data, and FIGS. 12 and 13 illustrate a part of the transaction history (block chain) in the electronic cryptographic rights document. To do.

  Rights book data and earthquake information in the electronic cryptography rights book are defined as a chain of a series of electronic signatures exemplified in FIG. When the owner of the rights document data transfers the rights document data D11 and the earthquake information D12 to the next owner (or stores them on the distributed database), the owner of the right document data and the next owner A digital signature of the hash value of the public key with its own private key is added to the rights document data D11 or the earthquake information D12. For the calculation of these hash values, for example, a one-way hash function such as SHA-256 or RIPEMD-160 is used.

  In FIG. 11, as a specific example of the transaction, the rights document data is transferred from the owner Z to the owner A, transferred from the owner A to the owner B, and further transferred from the owner B to the owner C. Is illustrated. In this case, when transferring the rights document data from the owner A to the owner B, the owner A is the hash value of the transfer transaction from the owner Z to the owner A and the owner who is the next owner. A digital signature of the hash value of B's public key and the secret key of owner A is added to the rights document data and the like.

  The owner of the entitlement data after this transaction including the owner B uses the hash value of the transfer transaction from the owner Z to the owner A and the owner B as the value obtained by decrypting the electronic signature with the public key of the owner A. It is possible to determine whether or not the transaction, the seismic observation result, and the real estate evaluation have been tampered with by comparing with the hash value of the public key.

  Similarly, when transferring the rights document data, etc. from the owner B to the owner C, the owner B sends the hash value of the transfer transaction from the owner A to the owner B and the owner C who is the next owner. The digital signature of the hash value of the public key with the secret key of the owner B is added to the rights document data. This makes it possible to determine whether or not the transfer transaction from the owner B to the owner C has been tampered with.

  The rights document data of each property can be defined as a chain of such a series of electronic signatures. Here, the hash value of the public key is a public address. In other words, the rights document data stored at this public address can be transferred only to those who can digitally sign real estate transactions with this public address as the transfer source, that is, those who have a private key corresponding to this public address. It is done. Therefore, the secret key is generally concealed so as not to be leaked to anyone other than the owner. Note that the rights document data and the like are stored at a public address associated with the current owner.

  In addition, since this electronic signature alone cannot verify that any of the past owners of the rights document data or the like has used the rights document data in a multiple manner (multiple assignment), this embodiment In the mechanism of the electronic cryptography rights document relating to the above, this multiple use is prevented by using a mechanism called a block chain exemplified in FIGS.

  As illustrated in FIGS. 12 and 13, each block in which the rights document data and the like are recorded stores a plurality of transactions, a nonce, and a hash value of the immediately preceding block. Nonce is a value discovered as a result of proof of work, and among the nodes (minor) 90a to 90f, the node (minor) that first discovered this value is the approver and the block in which the nonce is discovered is blockchained. Update blockchain by adding to the end of. As a result, a consistent transaction history is recorded in the block chain. By sharing this block chain among all the nodes 90a to 90f participating in the P2P network 20, a consistent transaction history can be obtained throughout the P2P network 20. Can be shared. That is, this block chain becomes a real estate transaction history database and a key information database, and becomes a database that stores earthquake measurement results, simulation results, and real estate evaluation results so that they cannot be tampered with. In the present embodiment, rights document data transactions and earthquake record / simulation results are disclosed by a mechanism using a public key cryptosystem.

  Here, proof of work is a mechanism for preventing forgery of rights document data, etc. due to malicious hacking, etc., and data (value) that must be calculated to authenticate each real estate transaction or such In this embodiment, a hash function is used as means for calculating a nonce. In real estate transaction approval, as described above, each transaction unit (block) of real estate includes Nonce, which is a random variable, in addition to information specifying the real estate and transaction information of the sender, etc. , Proof of Work is a hash value that starts from a series of “0” s of a certain number of times (the remaining data is optional if 0 continues for a certain number of times), and transaction approval is a non-rounded increase in Nonce To execute a proof-of-work from the hash calculation. At this time, since the original value cannot be calculated from the hash value, it is necessary to calculate the brute force.

  The approver of this proof of work is also called the miner (minor), the approval work is also called mining (mining), the approver from the price paid as the fee for the real estate transaction, For example, electronic currency is paid. In this embodiment, in order to prevent forgery of the right data, this calculation is set to take about 10 minutes. Forgery of rights document data means that transaction data is falsified, so the proof of work that must be found also changes, requiring recalculation.

  The important thing here is that past transaction data is also included in the block, and if you try to tamper with the transaction data, the transaction data (block) performed after that must be recalculated. In fact, there are many “good” calculators in addition to “malicious” attackers and counterfeiters, so counterfeiting becomes very difficult because the recalculation speed cannot keep up with the new transaction approval calculation speed. . In this way, proof of work plays the role of security in real estate transactions based on rights document data.

  In addition, the above-mentioned proof-of-work approval request and payment services such as remuneration may be performed on the real estate manager side device or communication service provider side device, such as a construction company, real estate agent, customer, etc. It may be performed by an application on a smartphone used by or by a server of an independent service management organization or financial institution.

(Operation during real estate transfer transaction)
By operating the real estate transaction system described above, the real estate transfer transaction method according to the present embodiment can be implemented. Note that the processing procedure described below is merely an example, and each processing may be changed as much as possible. Further, in the processing procedure described below, steps can be omitted, replaced, and added as appropriate according to the embodiment.

  Next, using FIG. 14 to FIG. 16, an operation example related to real estate transactions using the electronic cryptography rights document will be described. FIG. 14 is an explanatory diagram illustrating a processing procedure when the real estate transaction system according to the present embodiment is transferred, and FIG. 15 illustrates the relationship between the public key and the secret key according to the present embodiment. FIG. 16 is an explanatory diagram illustrating the procedure at the time of real estate transfer. Note that the processing procedure described below is merely an example, and each processing may be changed as much as possible. Further, in the processing procedure described below, steps can be omitted, replaced, and added as appropriate according to the embodiment.

  In the present embodiment, in the real estate transaction registration process and the key information update process, a mechanism of an electronic encryption right document using a distributed database is used. Here, a case where the resident Ua sells a property to a new occupant Ub through a real estate manager will be described as an example. As shown in FIG. 14, the real estate transaction transaction includes a public address and secret key issuance step S305, a related service history information registration processing step S306, and a right transfer processing execution step S307. Prior to the real estate transaction, earthquake information is always collected by the observation server 3 (S301). This earthquake information is disclosed within the authority of the information collection vehicle such as the real estate owner by the real estate owner. Is set (S302), stored in a node on the distributed ledger constituting the distributed database, and released (S303).

  Also in this data collection and analysis, as in the first embodiment, as shown in FIG. 7, a virtual grid (for example, 250 m square) is defined on the coordinates, and each area G1 defined by the grid is defined. The building group B1 existing inside may be performed together. In this case, the analysis result of each building included therein is averaged for each area G1 and displayed or disclosed for each area G1. Accordingly, the building from which the vibration detection report is acquired can be published as a vibration analysis of the entire area without individually specifying the building, and privacy related to the building can be protected.

Also, when disclosing earthquake information in step S303, it is preferable that the analysis results regarding each building as described above are averaged for each area so that individual buildings cannot be specified. In addition, for this earthquake information, the analysis results such as vibration, proof strength, strength, etc. regarding the structural material of the building subject to analysis are filtered according to the type of member, product, use location, aging, etc. It can be aggregated by processing, grouping processing, and sorting processing to be output, displayed, and published.
In addition, the protocol related to the collection, data storage, browsing, and disclosure of earthquake information uses generalized public technologies such as libraries and APIs based on open source, so that specific persons cannot be managed and operated exclusively. It is preferable to ensure the publicity and public interest of information.

  In step S305, the real estate manager side device 8 functions as an address issuing unit, and issues a pair of a public address PA3 unique to the property and a secret key SK3 corresponding to the property specific public address PA3. Specifically, as illustrated in FIG. 15, the real estate manager side device 8 uses a random number generator or the like to generate a secret key SK3 associated with a public address unique to the property using a public key cryptosystem. Generate. For example, the random number generator may be incorporated in the real estate manager side device 8 or the guarantee system cooperation unit of the observation server 3 as a program. As described above, this secret key SK3 is used for an electronic signature of a transaction (in this case, a sale from a real estate agent to a new occupant Ub) whose property is the property-specific public address PA3 to be paired.

  Next, an information processing terminal device such as a PC used by the real estate manager generates a public key PK3 from the private key SK3 based on an electronic signature algorithm such as an elliptic curve digital signature algorithm (ESDSA). To do. The generated public key PK3 and secret key SK3 form a key pair in the public key cryptosystem. Although the public key PK3 can be generated from the secret key SK3 due to the nature of this public key cryptosystem, the public key PK3 It is impossible to generate the secret key SK3 from the viewpoint of calculation amount. That is, the private key SK3 cannot be specified from the public key PK3, but the public key PK3 can be specified from the private key SK3. The type of electronic signature algorithm to be used is not limited to the elliptic curve DSA, and may be appropriately selected according to the embodiment.

  Subsequently, the real estate manager side device generates a property-specific public address PA3 from the public key PK3 by applying a one-way hash function such as SHA-256 or RIPEMD-160 to the public key PK3. For example, the property manager side device can generate the property-specific public address PA3 by applying SHA-256 to the public key PK3 twice. That is, the property-specific public address PA3 is a hash value of a public key used for the above-mentioned transaction signature, and is used to identify the transfer destination and transfer source of the electronic cryptographic right document. Since the one-way hash function is used to generate the property-specific public address PA3, the property-specific public address PA3 can be generated from the public key PK3 as shown in FIG. It is impossible to generate the public key PKa from the address PA3.

  In the next step S302, the service history data related to the property 3 such as the face-to-face communication service history provided while the resident Ua is in the property is linked to the property-specific public address PA3 generated in the step S305. To register. Specifically, as illustrated in FIG. 16, the property-specific history D2 for the property 3 is recorded as the face-to-face communication service execution history and recommendation matching results recorded by the communication service provider side device 7. It is published in association with the public address PA3. The property-specific history D2 can be freely browsed if the public key PK3 related to the property-specific public address PA3 is obtained.

  Thereafter, in step S306, the real estate manager side device 8 performs a right transfer transaction for the property-specific public address PA3 generated in step S305 in accordance with predetermined property transfer conditions. And if the said transfer is completed, the real estate manager side apparatus 8 will complete | finish the process which concerns on this operation example.

  Here, an application executed on the information processing terminal device Ma or Mb that can access the network can also be used for the exchange of the electronic encryption rights document according to the present embodiment. Therefore, in FIG. 16, an application for executing the mechanism of the electronic cryptography right document is installed in the guarantee system cooperation unit of the real estate manager side device 8, and by this application, a plurality of property-specific disclosures managed by the real estate broker The address is controlled.

  While the property belongs to the resident Ua, the rights document data D11 and the earthquake information D12 are stored in the terminal device Ma of the resident Ua and the public address PAa unique to the resident Ua is paired with the secret key SKa. When the property is transferred, the user Ua uses the terminal device Ma to transfer the property-specific property-specific public address PA3 generated by the real estate agent in step S305 from the public address PAa (transfer source). The rights document data D11 and the like can be transferred to (transfer destination).

  On the other hand, the occupant Ub who wishes to move in newly obtains the public key PK3 associated with the property using his / her terminal device Mb as illustrated in FIG. Ub can browse the property information associated with the property-specific public address PA3 of the property and the related property-specific history.

  Specifically, an application is also installed in the user terminal Mb of the user Ub, and the public address PAb held by the user Ub is managed by this application. The public address PAb is associated with its own secret key SKb, so that the rights document data D11 can be transferred from the public address PAb to another person. That is, with each secret key SKb, the user Ub can freely use the rights document data D11 stored in the public address PAb. Here, the user Ub uses the application at the user terminal Mb to receive the rights document data D11 and the like transferred from the property-specific public address PA3 to the public address PAb.

(Action / Effect)
According to the present embodiment described above, since a distributed database mechanism is adopted as the guarantee system, it is not necessary to provide a single facility for managing and operating a strong single system for each real estate agent. When transferring and receiving data, the shared database system for linking information, privacy protection, and advanced security measures against data tampering are secured by the distributed database mechanism, so the equipment cost and operation cost should be reduced. Can do.
