FIG. 1 is a block diagram of a system according to an embodiment of the present invention. FIG. 4 is a diagram illustrating an example of a transaction according to an embodiment of the present invention.

The data of the IOT terminal 100 is transferred to the data backhaul apparatus 200 included in the first transaction generated by the IOT terminal 100 and relaying the data. The data backhaul apparatus 200 creates a second transaction including address information to which the cost associated with the data transfer is to be transmitted in the first transaction and registers the second transaction in the data storage apparatus 400. At this time, the data storage device 400 may be a block chain. The block chain is formed by connecting blocks of all transaction records that are generated each time a transaction in which a virtual currency such as a bit coin is exchanged is formed as a block and connected in a chain form. The data storage device is a virtual money network Coin network). Bitcoin is a digital currency created by Satoshi Nakamoto in 2009, and has a structure that does not have a central device for issuing and managing currency. Instead, the bit coin transaction is performed by a P2P-based distributed database, and transactions are performed based on a public key cryptosystem. Bitcoin has anonymity and openness. The bit coin is stored in the form of a wallet file. Each wallet is given its own unique address, and a bit coin transaction is made based on that address. The bit coin trades between public accounts using a public key cryptosystem. All transactions are public and stored in a distributed database. Provide a series of proofs of work with a distributed time server to prevent duplicate spending. All transaction records must be stored in the database. Since the data storage device does not have a central server or a central control agency, it can not be hacked and thus has an advantage of security. In describing the present embodiment, the bit coin and data storage device technology is a well-known technology, so a detailed description will be omitted.

Referring to FIG. 1, the system according to the present embodiment includes an IOT terminal, a data backhaul apparatus, and an IOT server.

The IOT terminal 100 may refer to any device capable of connecting to the Internet that exists in the world including home appliances, office appliances, and public appliances. For example, the IOT terminal 100 may be a device equipped with a sensor capable of measuring temperature, and the temperature data measured by the sensor may be relayed through the wireless network 500 to the data backhaul apparatus 200 And may be registered in the data storage device 400. The wireless network 500 may be a non-charging wireless network such as WiFi, Bluetooth, or the like.

The IOT terminal 100 may store the virtual currency address information in advance through the input of the user. The virtual currency address information may be address information in which a certain amount of virtual money (for example, bit coin) is charged. At this time, one or more virtual money address information may exist. Assuming, for example, that the IOT terminal 100 operates for two years and transmits data once every time and transmits n virtual virtual currency (e.g., bit coin) in one transmission, a total of 24 * 365 * 2 * n virtual An address containing money (e.g., bit coin) may be stored in the IOT terminal 100, and one or more addresses may exist.

The IOT terminal 100 may generate a first transaction and transmit it to the data backhaul device 200. [

The first transaction may be generated in a structure capable of being registered and processed in a distributed digital book (e.g., a virtual money data storage device 400), and may be in the form of a message as shown in FIG. The first transaction may include data to be transmitted by the IOT terminal 100 and cost processing information according to transmission of the data. Specifically, the first transaction includes a transaction number, identification information (ID) of the IOT terminal 100 that generates and transmits a transaction, a data value to be transferred, a data transfer cost, and virtual currency address information May be included. The first transaction has the same message type as the second transaction to be described later, and there is only a difference such as A (see FIG. 4). A is an address information field to which a fee for transfer of the second transaction is to be remitted, and A is blank in the first transaction.

Since the IOT terminal 100 can not confirm whether the transmitted data is well transmitted, it is possible to transmit the same first transaction to the peripheral data backhaul apparatus 200 for a predetermined period of time to increase the transmission success rate.

The IOT terminal 100 may be a device that transmits data having different values at regular intervals. For example, it may be a temperature sensor for checking and transmitting the temperature value at a constant period.

The IOT terminal 100 repeatedly transmits the first transaction including the first data for a predetermined period of time (for example, until the second data is generated) at a predetermined period after the first data is generated. Then, the IOT terminal 100 stops transmission of the first transaction including the first data after a certain period of time and starts transmission of the first transaction including the new second data.

The data backhaul apparatus 200 serves as an intermediary for receiving the first transaction including data from the IOT terminal 100 and transmitting the first transaction to the data storage apparatus 400. At this time, a plurality of data backhaul apparatuses 200 may exist.

The data backhaul apparatus 200 may be a mobile terminal using the mobile network 600 as an apparatus having no limitation on mobility. For example, the mobile terminal may be a cellular phone. According to the present embodiment, the data backhaul apparatus 200 is not limited in terms of mobility, and there is no restriction in terms of coverage of data transmission when the IOT terminal 100 is installed. Meanwhile, although the data backhaul apparatus 200 is described as using a mobile network that is a charging wireless network, the data backhaul apparatus 200 may use a non-charging wireless network (e.g., WiFi).

The data backhaul apparatus 200 receives a first transaction from the IOT terminal 100 and confirms that the first transaction is registered in the data storage device 400. More specifically, it is checked whether the data included in the first transaction is registered in the data storage 400. The data backhaul apparatus 200 may send a duplicate check message for the first transaction to the IOT server 300 for the confirmation and discard the first transaction according to the response result of the IOT server 300 The second transaction may be generated and the second transaction may be transferred to the data storage device 400 to register the data of the IOT terminal 100. [ At this time, the duplicate check message may include identification information and transaction number of the IOT terminal 100 that has transmitted the first transaction. For example, the data backhaul apparatus 200 transmits a duplicate check message for the first transaction to the IOT server 300 to the IOT server 300, , The first transaction is discarded. However, when the data backhaul apparatus 200 receives a message from the IOT server 300 indicating that there is no same transaction in the data storage apparatus 400, it generates a second transaction and transmits the second transaction to the data storage apparatus 400 To register the data of the IOT terminal 100. [ At this time, the second transaction may be created in a structure capable of being registered and processed in a distributed digital book (for example, data storage 400 of virtual money), and may be in the form of a message as shown in FIG. The second transaction may further include address information to which the cost associated with the data transfer may be transferred to the information included in the first transaction. For example, the address information to which the cost associated with the data transmission may be transmitted may be identification information (ID, telephone number, etc.) of the mobile terminal. When registering the second transaction in the data storage device 400, that is, registering the data of the IOT terminal 100 in the data storage device 400, the mobile terminal can receive a payment for the transmission of the second transaction have. At this time, the cost is provided only to the mobile terminal that has registered the data of the transaction, that is, the IOT terminal 100, first.

The second transaction has the same message type as the first transaction described above, and there is only a difference such as A (see FIG. 4). The A is an address information field to which a fee for transfer of the second transaction is to be transmitted, and the A of the second transaction may include identification information of a mobile terminal transmitting and registering a second transaction to the data storage 400 . The identification information of the mobile terminal may be an ID or a telephone number.

As described above, the reason why the data backhaul apparatus 200 receiving the first transaction confirms that the first transaction is registered in the data storage apparatus 400 is that a fee is incurred due to indiscreet transfer of the first transaction . That is, the data backhaul apparatus 200 basically connects to a virtual money network (for example, a bit coin network) through a mobile network 600 (LTE, 3G) and transmits a transaction to the data storage apparatus 400 Accessing the mobile network 600 will incur costs. Therefore, it is checked whether the transaction to be registered in the data storage device 400 is duplicated in order to prevent the cost due to the use of the mobile network 600 indiscriminately according to the transmission of the already registered transaction.

In describing the present embodiment, it is described that a mobile network (LTE, 3G) in which charging is performed is used to transmit a second transaction, but the present invention is not limited to this. It is also possible to transmit a second transaction through a non- have. The charging wireless network (mobile network) or the non-charging wireless network (WiFi) for transmission of the second transaction may be arbitrarily selected by the user.

The IOT server 300 receives the transaction redundancy check message from the data backhaul apparatus 200, confirms the transaction redundancy check message, and transmits the confirmation result message to the data backhaul apparatus 200. The IOT server 300 may store the virtual currency address information in advance by the user, and the virtual currency address information may be mapped with the identification information of the IOT terminal 100 and stored. The duplicate check message may include identification information and transaction number of the IOT terminal 100 that has transmitted the first transaction.

For example, when the IOT server 300 receives the transaction duplication check message from the data backhaul apparatus 200, the IOT server 300 transmits the virtual currency address information (ID) mapped to the identification information of the IOT terminal 100, And checks the data storage device 400 corresponding to the virtual currency address information. At this time, the IOT server 300 checks whether the first transaction to be transmitted exists in the data storage device 400. The check for the existence of the first transaction can be confirmed through the matching of the transaction numbers. The IOT server 300 transmits a response message to the data backhaul apparatus 200 according to the presence or absence of a transaction number to be transmitted as a result of the check of the data storage apparatus 400, The transaction may be discarded or a second transaction may be created and registered in the data storage device 400. [

When the IOT server 300 confirms that the second transaction transmitted from the data backhaul apparatus 200 is finally registered by confirming the data storage apparatus 400, the IOT server 300 refers to the virtual money address information, Address (including the address information of the data backhaul apparatus 200 to which the cost associated with the data transfer included in the second transaction is to be remitted) to the device having the address so that the cost associated with the data relay can be paid.

2 is a diagram illustrating a configuration of a data backhaul apparatus 200 according to an embodiment of the present invention.

The data backhaul apparatus 200 serves as an intermediary for receiving the first transaction including data from the IOT terminal 100 and transmitting the first transaction to the data storage apparatus 400 do. The data backhaul apparatus 200 may be a mobile terminal using a mobile network, with no limitation on mobility. For example, the mobile terminal may be a cellular phone. At this time, the mobile terminal may include a data relay application, and the components included in the following data backhaul apparatus 200 may be included in the data relay application in a module form.

2, the data backhaul apparatus 200 may include a communication unit 210, a first transaction receiving unit 230, a transaction duplication check unit 250, and a transaction processing unit 270 .

The communication unit 210 controls the communication with the IOT terminal 100, the IOT server 300 and the data storage device 400 (for example, block chain), and controls the first communication unit and the second communication unit .

The first communication unit plays a role of activating a network function for communication with the IOT terminal 100. At this time, the network may be a non-charging wireless network such as WiFi or Bluetooth.

The second communication unit activates a network function for communication with the IOT server 300. In addition, the second communication unit may activate the network function to transmit the transaction to the data storage device (400). At this time, the network may be a mobile network such as LTE, 3G, or the like. The mobile network is a network where charges are made.

The first transaction receiving unit 230 may receive the first transaction from the IOT terminal 100. [ The first transaction may be generated in a structure capable of being registered and processed in a distributed digital book (e.g., a virtual money data storage device 400), and may be in the form of a message as shown in FIG. The first transaction may include data to be transmitted by the IOT terminal 100 and cost processing information according to transmission of the data. Specifically, the first transaction includes a transaction number, identification information (ID) of the IOT terminal 100 that generates and transmits a transaction, a data value to be transferred, a data transfer cost, and virtual currency address information May be included. The first transaction has the same message type as the second transaction to be described later, and there is only a difference such as A (see FIG. 4). A is an address information field to which a fee for transfer of the second transaction is to be remitted, and A is blank in the first transaction.

The transaction duplication check unit 250 checks whether the first transaction received by the first transaction receiving unit 230 is registered in the data storage device 400. The transaction duplication check unit 250 transmits a duplicate check message to the IOT server 300. The duplicate check message may include identification information and transaction number of the IOT terminal 100 that has transmitted the first transaction.

The transaction processor 270 may discard the first transaction or generate a second transaction according to a response received from the transaction duplication checker 250 and transmit the second transaction to the data storage device 400. For example, the transaction processor 270 discards the first transaction when the transaction duplication checker 250 receives a message from the IOT server 300 that the same transaction exists in the data storage 400. However, when the transaction duplication checker 250 receives a message from the IOT server 300 that the same transaction is not present in the data storage 400, the transaction processor 270 generates a second transaction, And transfers the transaction to the data storage device 400 to register the data of the IOT terminal 100. [ At this time, the second transaction may be created in a structure capable of being registered and processed in a distributed digital book (for example, data storage 400 of virtual money), and may be in the form of a message as shown in FIG. The second transaction may include address information to which a cost related to data transmission is to be transmitted to the information included in the first transaction. For example, the address information to which the cost associated with the data transmission may be transmitted may be identification information (ID, telephone number, etc.) of the mobile terminal. When registering the second transaction in the data storage device 400, that is, registering the data of the IOT terminal 100 in the data storage device 400, the mobile terminal can receive a payment for the transmission of the second transaction have. At this time, the cost is provided only to the mobile terminal that has registered the data of the transaction, that is, the IOT terminal 100, first.

The second transaction has the same message type as the first transaction described above, and there is only a difference such as A (see FIG. 4). The A is an address information field to which a fee for transfer of the second transaction is to be transmitted, and the A of the second transaction may include identification information of a mobile terminal transmitting and registering a second transaction to the data storage 400 . The identification information of the mobile terminal may be an ID or a telephone number.

The transaction processing unit 270 may transmit a second transaction when connected to a non-billing wireless network.

For example, the transaction processor 270 stores the second transaction in a queue until connection of the non-charging wireless network, and transmits the second transaction stored in the queue through the corresponding non-charging wireless network when the non-charging wireless network is connected .

The flow of data transfer according to the configuration of the data backhaul apparatus 200 of the present embodiment described above will now be described.

3 is a diagram illustrating a flow of data transmission using a data backhaul apparatus 200 according to an embodiment of the present invention.

In describing the present embodiment, the data backhaul apparatus 200 may be a mobile terminal using a mobile network as an apparatus having no limitation on mobility. For example, the mobile terminal may be a cellular phone. According to the present embodiment, the data backhaul apparatus 200 is not limited in terms of mobility, and there is no restriction in terms of coverage of data transmission when the IOT terminal 100 is installed. Meanwhile, although the data backhaul apparatus 200 is described as using a mobile network that is a charging wireless network, the data backhaul apparatus 200 may use a non-charging wireless network (e.g., WiFi).

Referring to FIG. 3, the data backhaul apparatus 200 according to the present embodiment receives a first transaction from the IOT terminal 100 (S310). The first transaction may be generated in a structure capable of being registered and processed in a distributed digital book (e.g., a virtual money data storage device 400), and may be in the form of a message as shown in FIG. The first transaction may include data to be transmitted by the IOT terminal 100 and cost processing information according to transmission of the data. Specifically, the first transaction includes a transaction number, identification information (ID) of the IOT terminal 100 that generates and transmits a transaction, a data value to be transferred, a data transfer cost, and virtual currency address information May be included. The first transaction has the same message type as the second transaction to be described later, and there is only a difference such as A (see FIG. 4). A is an address information field to which a fee for transfer of the second transaction is to be remitted, and A is blank in the first transaction.

The data backhaul apparatus 200 checks whether relay of the first transaction is possible (S320). For example, the data backhaul device 200 determines whether it is connected to a mobile network such as LTE, 3G, etc., which is a charging wireless network. If the data backhaul apparatus 200 is not connected to the mobile network, the data backhaul apparatus 200 stores the received first transaction in a separate storage space and adds it to the transmission queue. At this time, the first transaction may have an expire time, and may be deleted from the queue after the expiration time. When the expiration time passes, when the mobile terminal is connected to the mobile network, 1 transaction can be relayed. In the following description of the present embodiment, it is described that the relay transaction check of the first transaction is confirmed to be connected to a mobile network which is a charging wireless network. However, the present invention is not limited to this and may be connected to a non- It is also possible to check whether relaying is possible by checking whether or not it is possible to relay. For example, when the data backhaul apparatus 200 starts relaying only when it is connected to the non-charging wireless network by cutting off the connection state of the charging wireless network, the data backhaul apparatus 200 stores the second transaction in the queue until connection of the non- And may transmit the second transaction stored in the queue through the corresponding non-charging wireless network when the charging wireless network is connected.

If the data backhaul apparatus 200 is connected to the mobile network, the data backhaul apparatus 200 determines whether the first transaction is registered in the data storage apparatus 400 (S330). More specifically, it is checked whether the data included in the first transaction is registered in the data storage 400. For example, the data backhaul apparatus 200 may transmit a duplicate check message for the first transaction to the IOT server 300 for the confirmation, and may delete the first transaction according to the response result of the IOT server 300 Or may generate a second transaction and transfer the second transaction to the data storage device 400 to register the data of the IOT terminal 100. [ At this time, the duplicate check message may include identification information and transaction number of the IOT terminal 100 that has transmitted the first transaction.

When the data backhaul apparatus 200 transmits a duplicate check message for the first transaction to the IOT server 300 and receives a message indicating that the same transaction exists in the data storage apparatus 400 from the IOT server 300, 1 transaction is discarded (S360).

However, when the data backhaul apparatus 200 receives a message from the IOT server 300 indicating that there is no same transaction in the data storage apparatus 400, it generates a second transaction and transmits the second transaction to the data storage apparatus 400 To register the data of the IOT terminal 100 (S350). At this time, the second transaction may be created in a structure capable of being registered and processed in a distributed digital book (for example, data storage 400 of virtual money), and may be in the form of a message as shown in FIG. The second transaction may include address information to which a cost related to data transmission is to be transmitted to the information included in the first transaction. For example, the address information to which the cost associated with the data transmission may be transmitted may be identification information (ID, telephone number, etc.) of the mobile terminal. When the mobile terminal registers the second transaction in the data storage device 400, that is, registers the data of the IOT terminal 100 in the data storage device 400, the mobile terminal can receive payment for the transmission of the second transaction have. At this time, the cost is provided only to the mobile terminal that has registered the data of the transaction, that is, the IOT terminal 100, first.

The second transaction has the same message type as the first transaction described above, and there is only a difference such as A (see FIG. 4). The A is an address information field to which a fee for transfer of the second transaction is to be transmitted, and the A of the second transaction may include identification information of a mobile terminal transmitting and registering a second transaction to the data storage 400 . The identification information of the mobile terminal may be an ID or a telephone number.

530 is an interface for determining whether the data backhaul apparatus 200 activates the network in order to register the transaction in the data storage apparatus 400, that is, to register the data of the IOT terminal 100. That is, if the 530 interface is activated, the data backhaul apparatus 200 can transmit the second transaction and register the data in the data storage 400. The network is described as being a mobile network (LTE, 3G) in which charging is performed, but the present invention is not limited thereto, and it may be a non-charging wireless network such as WiFi.
