[0012] Hereinafter, an embodiment will be described with reference to the drawings. A system 1 for jointly owning a ship is a system for multiple owners to share a ship 10 having a unique ship ID. The ownership of the ship 10 can be shared by multiple owners with a predetermined share. The unique ship ID is an ID for identifying the ship, for example, a hull identification number.

[0013] As shown in FIG. 1, the system 1 for jointly owning a ship includes a cloud server 3 (an example of a computer) and a communication module 5.

[0014] The cloud server 3 is used for transferring the ownership of the ship 10, including buying and selling the ownership of the ship 10. The cloud server 3 is used for managing the ship 10 and distributing the profits from the rental of the ship 10.

[0015] The cloud server 3 is configured to be able to communicate with a plurality of purchasing user terminals 6 and a plurality of shared user terminals 7 (an example of a communication terminal) via the Internet IN. The cloud server 3 is used as a computer that manages the plurality of purchasing user terminals 6, the plurality of shared user terminals 7, and the ship 10.

[0016] The multiple purchasing user terminals 6 and the multiple sharing user terminals 7 are, for example, communication terminals such as smartphones, tablets, desktop computers, notebook computers, or wearable terminals.

[0017] The multiple purchasing user terminals 6 are used by users who wish to jointly own the ship 10. The multiple purchasing user terminals 6 are used by users who purchase part of the ownership of the ship 10. In this embodiment, the multiple purchasing user terminals 6 include a first purchasing user terminal 6a and a second purchasing user terminal 6b.

[0018] The multiple shared user terminals 7 are used by co-owners who have acquired partial ownership of the ship 10. The multiple shared user terminals 7 are used by users who co-own the ship 10. In this embodiment, the multiple shared user terminals 7 include a first shared user terminal 7a and a second shared user terminal 7b. For example, the first shared user terminal 7a may be the same terminal as the first purchasing user terminal 6a. That is, a co-owner of the ship 10 who has purchased partial ownership of the ship 10 using the first purchasing user terminal 6a may use the first purchasing user terminal 6a as the first shared user terminal 7a.

[0019] In the following description, the term "information" is used. This term "information" includes the meaning of "data."

[0020] The cloud server 3 is managed by, for example, a shipping company. As shown in Fig. 2, the cloud server 3 includes a processing unit 31, a storage device 32, a communication unit 33 (an example of a ship information providing unit), and an input unit 34.

[0021] The processing unit 31 includes a processor 31a and a memory 31b (an example of a storage unit). The processor 31a is, for example, a CPU. The processor 31a processes various types of information according to a program recorded in the memory 31b.

[0022] The memory 31b records various information processed by the processor 31a and various programs executed by the processor 31a. The memory 31b stores a smart contract 31c for performing a process for transferring ownership of the ship 10. The smart contract 31c in this embodiment is a program executed on a blockchain, and is a program that automatically executes processing such as a contract when predetermined conditions are met. The memory 31b includes a volatile memory such as a RAM and a non-volatile memory such as a ROM.

[0023] The storage device 32 records various information and various programs. The storage device 32 includes a storage device such as a hard disk and / or an SSD. The storage device 32 is used as, for example, a database. The storage device 32 may be included in the processing unit 31.

[0024] The communication unit 33 receives information and signals from the multiple purchasing user terminals 6, the multiple shared user terminals 7, and the ship 10. The information received from the multiple purchasing user terminals 6, the multiple shared user terminals 7, and the ship 10 is recorded in the memory 31b.

[0025] The communication unit 33 provides information and signals in response to information and signals received from the multiple purchasing user terminals 6, the multiple shared user terminals 7, and the ship 10. The communication unit 33 reads information to be transmitted to the multiple purchasing user terminals 6, the multiple shared user terminals 7, and the ship 10 from the memory 31b, and provides the information and signals.

[0026] The input unit 34 accepts input from the server administrator. Information and signals input to the input unit 34 are recognized by the processor 31a.

[0027] The communication module 5 is a Data Communication Module. The communication module 5 is attached to the ship 10. The communication module 5 is configured to be able to communicate with the cloud server 3 via the Internet IN. The communication module 5 is configured to be able to communicate with a plurality of shared user terminals 7. The communication module 5 includes a processor such as a CPU, and memories such as a RAM and a ROM. The memory stores information related to the ship 10.

[0028] The communications module 5 has a unique communications module ID. The communications module ID is an ID for identifying the communications module 5, and is uniquely set for the communications module 5.

[0029] The communication module 5 includes a position detection unit 51 and an engine operation detection unit 52. The position detection unit 51 detects position information of the communication module 5. The position detection unit 51 is, for example, a GPS receiver. The position detection unit 51 acquires the position information of the communication module 5 from a GPS satellite. The communication module 5 transmits the position information acquired by the position detection unit 51 to the cloud server 3. The cloud server 3 receives the position information of the communication module 5 via the communication module 5. The storage device 32 of the cloud server 3 stores the position information of the communication module 5. The communication module 5 transmits the position information of the communication module 5 to the cloud server 3 in response to requests from, for example, multiple shared user terminals 7.

[0030] The engine operation detection unit 52 detects the operating state of the engine of the ship 10. The engine operation detection unit 52 is, for example, a sensor that detects the engine speed. The engine operation information includes time series data of the engine speed. The communication module 5 transmits the engine information acquired by the engine operation detection unit 52 to the cloud server 3. The cloud server 3 receives the engine information via the communication module 5. The communication module 5 transmits the engine operation information to the cloud server 3 in response to requests from, for example, multiple shared user terminals 7.

[0031] The cloud server 3 acquires and stores information regarding the joint ownership of the ship 10 (S31 in FIG. 3). The information regarding the joint ownership of the ship 10 is acquired, for example, by accepting an input from a server administrator. The memory 31b of the processing unit 31 of the cloud server 3 stores the acquired information regarding the joint ownership of the ship 10.

[0032] The information regarding the joint ownership of the ship 10 includes information regarding the ship ID of the ship 10 and the communication module ID of the communication module 5. The processing unit 31 of the cloud server 3 links the ship ID of the ship 10 and the communication module ID of the communication module 5 and stores them in the processing unit 31 or the storage device 32. A part of the processing unit 31 of the cloud server 3 is an example of a linking unit.

[0033] The information regarding the joint ownership of the vessel 10 includes, for example, information regarding the joint owners of the vessel 10, the ownership percentage of each joint owner of the vessel 10, and information regarding rights such as revenue rights and use rights of the vessel 10.

[0034] The information regarding the joint ownership of the vessel 10 includes information regarding the joint purchase of the vessel 10. The information regarding the joint purchase of the vessel 10 includes at least one of the operating status of the vessel 10, revenue information of the vessel 10, and photographs of the vessel 10. The information regarding the joint purchase of the vessel 10 may include joint purchase terms indicating the shares available for purchase and their prices, an evaluation of the user of the vessel 10, maintenance costs of the vessel 10, the shareholding ratio of the vessel 10, and information regarding rights such as revenue rights and usage rights of the vessel 10. The photographs of the vessel 10 may include photographs of the vessel 10 taken by the user of the vessel 10.

[0035] The cloud server 3 executes the publication of information relating to the joint purchase of the ship 10 (S32 in FIG. 3). For example, when information relating to the joint purchase of the ship 10 is provided to the cloud server 3 by input from a server administrator, the processing unit 31 of the cloud server 3 stores the information and executes the publication of the information relating to the joint purchase of the ship 10. The information relating to the joint purchase of the ship 10 is published, for example, on a website provided by the cloud server 3.

[0036] For example, when the cloud server 3 receives information about the first user and the shares to be purchased from the first user using the first purchasing user terminal 6a, the cloud server 3 determines whether the first user satisfies the purchase conditions (S33, S34 in FIG. 3). If the cloud server 3 determines that the first user satisfies the purchase conditions, it automatically executes the purchase process including the payment process and the ownership transfer process using the smart contract 31c (S35 in FIG. 3). Similarly, when the cloud server 3 receives information about the second user and the shares to be purchased from the second user using the second purchasing user terminal 6b, it automatically executes the purchase process if it determines that the first user satisfies the purchase conditions.

[0037] The cloud server 3 assigns an individual identification ID to each of the joint owners and provides the identification ID to the communication module 5. For example, when the ship 10 is jointly owned by a first user and a second user, the cloud server 3 assigns an individual identification ID to each of the first user and the second user and transmits information related to the identification ID to the communication module 5 (S36 in FIG. 3). The communication module 5 stores the identification ID provided by the cloud server 3. The individual identification IDs assigned to each of the first user and the second user are stored in the communication module 5. Note that the cloud server 3 does not provide the communication module 5 with the individual identification IDs of users who do not have the right to use the ship 10, for example, among the joint owners of the ship 10. The following description is based on the assumption that all of the joint owners of the ship 10 (here, the first user and the second user) have the right to use the ship 10.

[0038] The communication module 5 is configured to be able to communicate with multiple shared user terminals 7, and upon receiving an unlock signal for unlocking the key lock of the ship 10, including information regarding the identification ID, from the multiple shared user terminals 7, the communication module 5 unlocks the ship 10 based on the unlock signal. In this embodiment, the communication module 5 is configured to be able to communicate with the first shared user terminal 7a and the second shared user terminal 7b, and upon receiving an unlock signal for unlocking the key lock of the ship 10, including information regarding the identification ID, from the first shared user terminal 7a or the second shared user terminal 7b, the communication module 5 unlocks the ship 10 based on the unlock signal.

[0039] The system 1 for jointly owning a ship includes a ship position detection unit 20 and an RFID (Radio Frequency Identification) tag 40. In this embodiment, the communication module 5 includes the ship position detection unit 20.

[0040] The ship position detection unit 20 detects ship position information of the ship 10. The ship position detection unit 20 is, for example, a GPS receiving unit. The ship position detection unit 20 acquires the ship position information from a GPS satellite. The processing unit 11 that controls the ship 10 transmits the ship position information acquired by the ship position detection unit 20 to the cloud server 3. The cloud server 3 receives the ship position information acquired by the ship position detection unit 20 via the processing unit 11 of the ship 10.

[0041] The RFID tag 40 is embedded in the ship 10. The RFID tag 40 stores information about the ship. The communication module 5 includes an RFID reading unit 53 capable of reading the RFID tag 40. The RFID reading unit 53 is capable of reading the RFID tag 40 in a non-contact manner. The RFID reading unit 53 periodically reads the RFID tag 40. The communication module 5 transmits the reading result of the RFID reading unit 53 to the cloud server 3.

[0042] The cloud server 3 provides the information about the ship 10 received from the communication module 5 in response to a request from the first shared user terminal 7a or the second shared user terminal 7b. The information about the ship 10 includes position information of the communication module 5, engine operation information, ship position information of the ship 10, read result information of the RFID reading unit 53, photos of the ship 10 taken by a vehicle using the ship 10, etc.

[0043] The cloud server 3 receives input from the server administrator or the co-owner of the ship 10, and records the ship 10's rental condition information (S41 in FIG. 4). The cloud server 3 publishes the information on the ship 10's rental conditions (S42 in FIG. 4). The information on the ship 10's rental conditions is published, for example, on a website provided by the cloud server 3.

[0044] When the cloud server 3 receives borrowing request information corresponding to the response to the rental condition information from the user terminal of the rental user who wishes to rent the ship 10, the cloud server 3 determines whether the rental user satisfies the rental conditions based on the borrowing request information (S43, S44 in FIG. 4). If the cloud server 3 determines that the rental user satisfies the rental conditions, it automatically executes the rental process and the payment process using the smart contract 31c (S45 in FIG. 4).

[0045] After executing the rental process of the ship 10, the cloud server 3 transmits an unlock signal to the communication module 5 to release the key lock of the ship 10. The cloud server 3 accepts input from the user terminal of the renting user. When the cloud server 3 determines, in response to the input from the user terminal of the renting user, that the user terminal of the renting user has approached the ship 10, it transmits an unlock signal to the communication module 5.

[0046] The communications module 5 executes unlocking of the vessel 10 based on the unlock signal. When the cloud server 3 acquires information regarding the end of rental from the user terminal of the rental user, it transmits a lock signal for key-locking the vessel 10 to the communications module 5. When the communications module 5 receives the lock signal, it executes key-locking of the vessel 10 based on the lock signal.

[0047] The system 1 for jointly owning a ship distributes the profits from the rental of the ship 10 to the co-owners in accordance with their ownership percentage of the ship 10. The cloud server 3 distributes the profits from the rental of the ship 10 to the co-owners in accordance with their ownership percentage of the ship 10. The cloud server 3, for example, calculates the profits from the rental of the ship 10 on a monthly basis. The cloud server 3 executes the distribution process based on information regarding the distribution destination of each co-owner, such as account information stored in the storage device 32 (S46 in FIG. 4). The cloud server 3 may execute the distribution process each time profits from the rental of the ship 10 are generated.

[0048] The system 1 for jointly owning a ship includes a maintenance information providing terminal 60. The maintenance information providing terminal 60 is used by a maintenance company responsible for maintaining the ship 10. The maintenance information providing terminal 60 is configured to be able to communicate with the cloud server 3. The maintenance information providing terminal 60 is, for example, a communication terminal such as a smartphone, a tablet, a desktop computer, a notebook computer, or a wearable terminal. The storage device 32 of the cloud server 3 stores, for example, a maintenance ID assigned to the maintenance company in association with a ship ID or a communication module ID.

[0049] The maintenance information providing terminal 60 provides maintenance information of the ship 10 to the cloud server 3. The maintenance information includes information related to the content of maintenance work for the ship 10. The maintenance information includes information related to the maintenance costs for the ship 10. The information related to the maintenance costs includes information related to fuel calibration, fuel refueling, etc.

[0050] The cloud server 3 accepts a deposit from the joint owner of the ship 10 (S51 in FIG. 5). The deposit from the joint owner of the ship 10 is managed using the smart contract 31c, and the cloud server 3 executes a payment process for the maintenance cost from the deposit based on information on the maintenance cost from the maintenance information providing terminal 60 (S52 in FIG. 5).

[0051] The cloud server 3 sets the allocation of the maintenance cost according to the usage ratio of the joint owners' ship 10. The cloud server 3 determines the burden ratio of the maintenance cost according to, for example, the usage ratio of the ship 10 between the first user and the second user.

[0052] The cloud server 3 monitors the remaining deposit (S53 in FIG. 5). If the deposit of a co-owner is insufficient, the cloud server 3 provides the identification ID of the co-owner with the insufficient deposit to the communications module 5 (S54 in FIG. 5). For example, if the cloud server 3 determines that the deposit balance of the first user is below a predetermined amount, it provides the identification ID of the first user to the communications module 5. In addition, the cloud server 3 notifies the first shared user terminal 7a of the first user with the insufficient deposit that there is an insufficient deposit.

[0053] When the communication module 5 receives an unlock signal including information regarding the identification ID of a joint owner with an insufficient deposit, the communication module 5 does not unlock the vessel 10. Therefore, if the first user's deposit balance is below a predetermined amount, the first user cannot unlock the vessel 10. Note that when the first user's insufficient deposit balance is resolved, the communication module 5 lifts the restriction on unlocking via the cloud server 3.

[0054] The cloud server 3 publishes information regarding the sale of ownership of a joint owner with an insufficient deposit. For example, if the cloud server 3 determines that the first user's insufficient deposit balance has continued for a predetermined period of time, the cloud server 3 publishes information regarding the sale of the first user's ownership of the ship 10 (S55 in FIG. 5). In conjunction with publishing the information regarding the sale of the first user's ownership of the ship 10, the cloud server 3 publishes information regarding the joint ownership of the ship 10 (S56 in FIG. 5).

[0055] For example, when the cloud server 3 receives information about the third user and the share to be purchased from a third purchasing user terminal used by a third user who wishes to jointly own the ship 10, the cloud server 3 determines whether or not the third user meets the purchase conditions. If the cloud server 3 determines that the third user meets the purchase conditions, it automatically executes a purchase process including a payment process and an ownership transfer process using the smart contract 31c. As a result, the first user's share in the ship 10 is sold to the third user, and the first user's ownership of the ship 10 is transferred to the third user.

[0056] At this time, if the maintenance costs that should be borne by the first user have not been paid, the cloud server 3 executes a payment process in which, for example, the proceeds from the sale of the first user's ownership interest in the ship 10 are allocated to the maintenance costs, and the amount obtained by deducting the maintenance costs from the proceeds from the sale is paid to the first user.

[0057] In the system 1 for jointly owning a ship described above, the cloud server 3 stores the ship ID and the communication module ID in association with each other, which prevents the management of the ship 10 from becoming complicated. Furthermore, the information about the ship 10 received from the communication module 5 is provided in response to a request from the first shared user terminal 7a or the second shared user terminal 7b, so that the joint owners can easily know, for example, the usage status of the ship 10 and the current location information of the ship 10. This allows the ship 10 to be jointly owned with peace of mind.

[0058] <Other embodiments> The number of the purchasing user terminals 6 and the number of the shared user terminals 7 may be three or more. The number of joint owners of the ship 10 may be three or more.

[0059] The cloud server 3 may release information regarding the sale of the ownership rights of the co-owners by, for example, accepting an input from the first shared user terminal 7a or the second shared user terminal 7b. That is, when a co-owner wishes to sell his / her share,

[0060] In the embodiment described above, the key lock and key lock release of the ship 10 are performed via the cloud server 3. However, the key lock and key lock release of the ship 10 may also be performed by having multiple shared user terminals 7 directly communicate with the communication module 5.
