Description

Data sharing apparatus and method {Data sharing apparatus and method}

The present invention relates to an apparatus and method for sharing data, and more particularly, to an apparatus and method for distributing and sharing data by combining blockchain technology with a network.

The reason for the current high mobile data rates can be attributed to the centralized structure of the mobile communication infrastructure.

Since 4G LTE uses a frequency band of approximately 1 to 6 GHz, each mobile carrier must install a cell tower approximately every 3 to 30 km to provide 4G LTE service.

In the case of 5G, it is expected to use a higher frequency band, 20 to 60 GHz. Physically, using a high frequency band increases data transmission speed but shortens the reach, so mobile carriers must build cell towers more densely.

Wi-Fi has low coverage and high installation marginal cost. Wi-Fi was fundamentally designed for high speed and low coverage. Accordingly, in order to overcome the short effective range and build a Wi-Fi infrastructure that exists anywhere, high cost is required to additionally install wires, APs, amplifiers, routers, switches, etc., and continuous maintenance costs are required.

In addition, Wi-Fi has a low return on investment and is limited in opening and maintenance. Many studies have shown that Wi-Fi in workplaces makes consumers stay longer and increases sales. However, in reality, most business owners consider Wi-Fi as part of an additional service and think that its contribution to sales is remarkably low. Therefore, there is a lack of motivation to provide stable Internet to everyone by opening Wi-Fi. Currently, Wi-Fi in workplaces is often locked with a password and used on a limited basis or is open without maintenance.

And, no one is responsible for security on the Internet network. Worldwide, Internet Service Providers and Wi-Fi AP owners hold no responsibility for Internet hacking.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail. In order to facilitate overall understanding in the description of the present invention, the same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components are omitted.

1 is a configuration diagram for explaining a data sharing system according to an embodiment of the present invention, FIG. 2 is a diagram showing an example of a mesh network by mobile terminals connected to the access point shown in FIG. 1, and FIG. 4 is a diagram illustrating Wi-Fi coverage extension according to an embodiment of the present invention.

The data sharing system shown in FIG. 1 includes a network 10, an access point 20, an AP sharer terminal 30, a mobile communication sharer terminal 40, an Internet relay sharer terminal 50, an encryption server 60, It includes a proxy server 70, an advertiser terminal 80, an advertisement execution server 90, and a relay server 100.

Network 10 is a blockchainized network.

For example, the network 10 may be implemented as a wired network such as a Local Area Network (LAN), a Wide Area Network (WAN), or a Value Added Network (VAN). In addition, the network 10 includes a mobile radio communication network, a satellite communication network, Bluetooth, Wireless Broadband Internet (Wibro), High Speed Downlink Packet Access (HSDPA), Wi-Fi, and Long Term LTE (LTE). Term Evolution) can be implemented in all kinds of wireless networks. If necessary, the network 10 may be a network in which wired and wireless networks are mixed.

The access point 20 (Access Point; AP) helps wireless Internet access so that a wireless Internet user's terminal can access the network 10 and use Internet services. Here, the terminal of the wireless Internet user may be the AP sharer terminal 30, the mobile communication sharer terminal 40, the Internet relay sharer terminal 50, and the advertiser terminal 80. In FIG. 1, only one access point 20 is shown, but it should be seen that there are actually a plurality of them.

The access point 20, that is, a wireless access point (WAP) refers to a device that allows wireless devices to connect to wired devices using a related standard using Wi-Fi in a computer network. A WAP is generally connected to a router through a wired network and can relay data between wireless devices such as computers and printers and wired devices on the network.

The access point 20 may set an encryption server 60 . 1 shows one encryption server 60 on the network 10, it should be understood that there are actually a plurality of encryption servers. Accordingly, the access point 20 may request client authentication to the encrypted server 60 mapped among the plurality of encryption servers 60 for client authentication.

In FIG. 1 , an AP sharer terminal 30 is a terminal of an owner who owns an access point 20 and allows the access point 20 to be shared with terminals of other participants on the network 10 .

Of course, the AP sharer terminal 30 may also be a sharer terminal that shares the access point 20 .

The AP sharer terminal 30 is loaded with a predetermined application or SDK (Software Development Kit) capable of receiving the data sharing service according to the present invention.

The AP owner can participate in a data sharing service by registering the access point 20 owned (possessed) in the network 10 by manipulating the terminal 30 of the AP owner. In this case, by registering the password of the access point 20 encrypted with WPA2/PSK in an encrypted form in the block chain of the network 10, other users (sharers) using the network 10 do not know the password. Access point 20 is available. In addition, by registering the RADIUS server of the access point 20 encrypted with 802.1x EAP as the encryption server 50 on the blockchain network, other users (sharers) using the network 10 can safely access the access point 20 make it available

If a person who wants to receive Internet service through the network 10 owns (possession) an incompatible access point, a compatible access point is provided from an AP provider (not shown) and can be shared by other users. All you have to do is build a wireless network.

For example, the AP sharer terminal 30 may be implemented as a portable terminal or a portable computer. Here, the portable terminal is a wireless communication device that guarantees portability and mobility, and includes Personal Communication System (PCS), Global System for Mobile communications (GSM), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), and Personal Digital Communication (PDA). Assistant), International Mobile Telecommunication (IMT)-2000, Code Division Multiple Access (CDMA)-2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (Wibro), Wi-Fi, LTE ( It may include all kinds of handheld-based wireless communication devices such as Long Term Evolution terminals. Portable computers may include notebooks, laptops, and the like.

In addition, the AP sharer terminal 30 may be various smart devices such as a smart phone, a smart note, a tablet PC, and a wearable computer.

The AP sharer terminal 30 may register its own access point in the block chain on the network, and the registered information (eg, information on the access point) is a terminal for proof-of-work (ie, on the network) among all terminals on the network. It is propagated to some of all terminals). After verifying the corresponding registration information, the terminal for proof-of-work generates a block (including registration information) based on it. Thereafter, the terminal for proof-of-work propagates the generated block to all other terminals on the network 10. In this way, all terminals on the network 10 can easily know information about the access point by checking the block.

Here, the account information of the AP sharer terminal 30 is stored in a virtual currency pool (not shown). A cryptocurrency pool is formed on the network 10. The virtual currency pool operates virtual currency (eg, named Anycoin), and all other terminals (including servers) on the network 10 (40, 50, 60, 70) as well as the account information of the AP sharer terminal 30 , 80, 90, 100) account information is managed.

In other words, the virtual currency pool is a block (generated by triggering a smart contract) based on the sharing history of sharing the access point (e.g., number of users shared, amount of shared data, shared connection time, etc.) Cryptocurrency is paid to the person who provided the share by checking the virtual currency transaction details). Here, the meaning of paying virtual currency does not mean directly paying virtual currency, but updating the account information of the person who provided the share and the account information of the person who received the share. For example, when participant A shares an access point, the access point propagates the sharing details to the terminal for proof-of-work. The terminal for proof-of-work verifies the sharing details and creates a block (including sharing details and virtual currency transaction details) as the verification succeeds. And, the terminal for proof-of-work propagates the generated block to all other terminals. At this time, since the block (including sharing details and virtual currency transaction details) is transmitted to the virtual currency pool, the virtual currency pool can check the corresponding transaction details in the propagated block. After confirmation, the virtual currency pool deducts A won in virtual currency from participant A's account according to the virtual currency transaction details and increases the virtual currency A won to the account of the AP sharer terminal. In this way, the service pool performs renewal to increase the virtual currency in the account of the person who provided the share, and performs renewal to deduct the virtual currency in the account of the person who was provided with the share. Accordingly, when one or more sharer terminals share data through an access point, the owner's terminal of the corresponding access point (ie, the AP sharer terminal 30) determines the amount of data shared (eg, data packet amount, time, etc.) In response, it can be said that virtual currency is issued.

In the case of the above block, a structure in which a plurality of blocks are sequentially connected according to the generation order may be obtained by including a hash value of a previously generated block in the current block. A structure in which a plurality of blocks are sequentially connected as described above may be referred to as a block chain. The security stability of the blockchain increases as more sharers share data. In other words, in the block chain, it can be seen that blocks including details of sharing between all sharer terminals on the network 10 and details of issuance/transaction of virtual currency are connected in a chain form.

A sharer who wants to receive value within the network 10 pays virtual currency to a virtual currency pool (not shown). Here, virtual currency may be, for example, a token such as Ethereum's ERC-20 protocol or a new coin. Cryptocurrency can be traded based on blockchain. Virtual currency can be seen as playing a key role in motivating participants who participate in the data sharing service in the present invention to provide value to other participants.

As more participants share the access point 20 through such virtual currency issuance, participants can access the access point 20 from more places.

On the other hand, by registering the possessed access point 20 to the network 10 as described above, access authority of the access point 20 can be easily managed. Access authority can be easily registered, changed, or deleted with a simple UI without the need to verbally inform the password of the access point 20 .

In FIG. 1 , the mobile communication sharer terminal 40 may receive a desired Internet service through a mobile communication network (eg, LTE network) of the network 10 .

Although only one mobile communication sharer terminal 40 is shown in FIG. 1 , a plurality of them may actually exist.

The mobile communication sharer terminal 40 is loaded with a predetermined application or SDK capable of receiving the data sharing service according to the present invention.

For example, the mobile communication sharer terminal 40 may be implemented as a portable terminal or a portable computer. Here, the portable terminal is a wireless communication device that guarantees portability and mobility, and includes Personal Communication System (PCS), Global System for Mobile communications (GSM), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), and Personal Digital Communication (PDA). Assistant), International Mobile Telecommunication (IMT)-2000, Code Division Multiple Access (CDMA)-2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (Wibro), Wi-Fi, LTE ( It may include all kinds of handheld-based wireless communication devices such as Long Term Evolution terminals. Portable computers may include notebooks, laptops, and the like.

In addition, the mobile communication sharer terminal 40 may be various smart devices such as a smart phone, a smart note, a tablet PC, and a wearable computer.

Here, the mobile communication sharer terminal 40 may be a terminal that shares a mobile communication network (eg, LTE network) to which it is connected with other sharer terminals existing in the network 10 . In this case, the corresponding mobile communication sharer terminal 40 shares LTE data that has already been purchased or to be purchased with other sharers, and receives virtual currency corresponding to the amount of shared data. Here, being issued virtual currency means that the account information of the corresponding mobile communication sharer terminal 40 is updated, rather than being directly issued virtual currency.

Mobile communication network data (eg, LTE data) held by the mobile communication sharer terminal 40 is shared with other sharers through P2P wireless network technology, so that other sharers can use the mobile communication network (eg, LTE network). In this case, the mobile communication sharer terminal 40 can provide Internet service to other sharers in an area where a mobile communication network is not installed or it is difficult to use a nearby mobile communication network such as a means of transportation.

For example, when the mobile communication sharer terminal 40 shares the connected mobile communication network with another sharer terminal of the network 10, the mobile communication sharer terminal 40 propagates the sharing details to the terminal for proof-of-work. . The terminal for proof-of-work verifies the corresponding sharing details and generates a block (including sharing details and virtual currency transaction details generated by triggering a smart contract) as the verification succeeds. And, the terminal for proof-of-work propagates the generated block to all other terminals. At this time, since the block (including sharing details and virtual currency transaction details) is transmitted to the virtual currency pool, the virtual currency pool can check the corresponding transaction details in the propagated block. After confirmation, the virtual currency pool deducts virtual currency A won from the account of the corresponding sharer terminal that has shared the mobile communication network according to the virtual currency transaction details, and transfers it to the account of the corresponding mobile communication sharer terminal 40 that provided sharing of the mobile communication network. Increase the virtual currency A won. In this way, the service pool performs renewal to increase the virtual currency in the account of the person who provided the share, and performs renewal to deduct the virtual currency in the account of the person who was provided with the share.

Accordingly, when one or more other sharer terminals share the mobile communication network to which they are connected, the mobile communication sharer terminal 40 that provides sharing of the mobile communication network corresponds to the amount of data shared (eg, data packet amount, time, etc.) Thus, it can be said that virtual currency is issued.

Meanwhile, the mobile communication sharer terminal 40 may be a terminal that shares a mobile communication network (eg, LTE network) connected by another person.

In FIG. 1 , the Internet relay sharer terminal 50 may perform tethering on the network 10 . Here, tethering is a service in which, for example, a mobile device connected to the Internet serves as a repeater to enable Internet access to other nearby devices.

In FIG. 1, only one Internet relay sharer terminal 50 is shown, but in reality, there may be a plurality of them.

The Internet relay sharer terminal 50 is loaded with a predetermined application or SDK capable of receiving the data sharing service according to the present invention.

For example, the Internet relay sharer terminal 50 may be implemented as a portable terminal or a portable computer. Here, the portable terminal is a wireless communication device that guarantees portability and mobility, and includes Personal Communication System (PCS), Global System for Mobile communications (GSM), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), and Personal Digital Communication (PDA). Assistant), International Mobile Telecommunication (IMT)-2000, Code Division Multiple Access (CDMA)-2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (Wibro), Wi-Fi, LTE ( It may include all kinds of handheld-based wireless communication devices such as Long Term Evolution terminals. Portable computers may include notebooks, laptops, and the like.

In addition, the Internet relay sharer terminal 50 may be various smart devices such as a smart phone, a smart note, a tablet PC, and a wearable computer.

Here, the Internet relay sharer terminal 50 shares the access point 20 to which it is connected to other sharer terminals existing in the network 10, and the wireless Internet (eg, Wi-Fi) shared by other wireless Internet sharers again. It may be a sharing terminal, a terminal sharing a mobile communication network (eg, LTE network) shared by a mobile communication network sharer, and the like. In this case, the Internet relay sharer terminal 50 receives virtual currency corresponding to the amount of data tethered to other sharer terminals. Here, being issued virtual currency does not mean directly issuing virtual currency, but means that one's account information is updated based on the virtual currency corresponding to the amount of data provided for sharing. The Internet relay sharer terminal 50 shares an access point that has not yet been registered with the network 10, solves the problem of lack of initial participants, and solves the fundamentally short reach problem of wireless Internet (eg, Wi-Fi). In addition, the short reach of the mobile communication sharer terminal is also extended.

For example, the above-described Internet relay sharer terminal 50 shares the access point 20 to which it is connected to another sharer terminal existing in the network 10, or a wireless Internet shared by another wireless Internet sharer (eg, Wi-Fi). ) or when the mobile communication network (eg, LTE network) shared by the mobile communication network sharer is shared again, the Internet relay sharer terminal 50 transmits the sharing details to a terminal for proof-of-work (some terminals on the network) spread to The terminal for proof-of-work verifies the corresponding sharing details and generates a block (including sharing details and virtual currency transaction details generated by triggering a smart contract) as the verification succeeds. And, the terminal for proof-of-work propagates the generated block to all other terminals. At this time, since the block (including sharing details and virtual currency transaction details) is transmitted to the virtual currency pool, the virtual currency pool can check the corresponding transaction details in the propagated block. After confirmation, the virtual currency pool deducts virtual currency A won from the account of the terminal that received Internet relay sharing according to the virtual currency transaction details, and increases the virtual currency A won to the account of the terminal that provided Internet relay sharing. In this way, the service pool performs renewal to increase the virtual currency in the account of the person who provided the share, and performs renewal to deduct the virtual currency in the account of the person who was provided with the share.

Accordingly, it can be said that the terminal providing Internet relay sharing receives virtual currency in response to the amount of shared data (eg, the amount of data packets, etc.).

If necessary, the AP sharer terminal 30, the mobile communication sharer terminal 40, and the Internet relay sharer terminal 50 may request connection to the proxy server 70 and use the same. On the other hand, the AP sharer terminal 30, the mobile communication sharer terminal 40, and the Internet relay sharer terminal 50 request the use of a VPN (Virtual Private Network) (not shown) to access the virtual hypothetical network After that, the virtual hypothetical network can be used.

As shown in FIG. 2, a distributed mesh network can be formed centering on devices that want to share the Internet by the above-described access point 20 and sharer terminals 30, 40, and 50. Of course, when a wireless P2P technology with a higher speed or a wider range is commercialized, it is natural that it can be replaced or mixed. Devices directly or indirectly connected to devices that want to share the Internet through the distributed mesh network can use the Internet. In FIG. 2, only reference numeral 40 is indicated for the sharer terminal, but the AP sharer terminal 30, the mobile communication sharer terminal 40, and the Internet relay sharer terminal 50 may coexist.

In addition, as shown in FIGS. 3 and 4, as the wireless mesh network is configured between the sharer terminals 30, 40, and 50, the effective range of the wireless Internet (eg, Wi-Fi) can be greatly increased, and LTE in steps 3 and 4 It is possible to obtain the performance of a mobile communication network of the same level, and to obtain connection continuity because the network can be reconfigured in real time. In particular, with a small number of access points, ubiquitous Wi-Fi accessibility can be achieved at no additional cost. In FIG. 3, only reference numeral 40 is indicated for the sharer terminal, but the AP sharer terminal 30, the mobile communication sharer terminal 40, and the Internet relay sharer terminal 50 may coexist.

By forming a wireless mesh network as shown in FIGS. 3 and 4, Internet quality can be guaranteed and wireless Internet resources can be shared. For example, a multi-hop or multi-peer wireless Internet resource sharing service can be provided.

A process of establishing an encryption communication channel between the sharer terminals 30, 40, and 50 and the access point 20 may be described as follows. First, the sharer terminals 30, 40, and 50 request EAP authentication and encryption from the encryption server 50 to the access point 20 to establish a communication channel. Accordingly, the access point 20 relays the EAP authentication and encryption request to a specified (that is, mapped) encryption server 60 among a plurality of encryption servers 60 through the network 10 . After the encryption server 60 performs client authentication, the result (that is, EAP authentication success or not and encryption key) is delivered to the corresponding access point 20 through the network 10 . Then, the access point 20 transfers the EAP authentication success or not and the encryption key to the corresponding sharer terminal. Accordingly, a communication channel is formed between the corresponding sharer terminal (any one of the 30, 40, and 50) and the access point 20.

In addition, as the communication channel is formed, the corresponding sharer terminal (one of the 30, 40, and 50) can use the access point 20 designated by itself, and use the encryption key to send the desired information to the access point 20. You can request and receive data.

In FIG. 1, the encryption server 60 establishes encryption communication between the access point 20 and the sharer terminals 30, 40, 50. Although only one encryption server 60 is shown in FIG. 1, it is safe to assume that a plurality of encryption servers 60 exist.

The encryption server 60 serves as a RADIUS server on the network 10 and may be referred to as an Extensible Authentication Protocol (EAP) encryption node.

When a sharer terminal requests a connection to the access point 20, the access point 20 sends connection request information (eg, packet) to the encryption server 60. Accordingly, the encryption server 60 propagates the connection request information to a node (ie, a terminal for authentication and encryption) (not shown) on the network 10 . The encryption server 60 transmits the result value (eg, including authentication success and encryption key) at the node according to the triggering of the smart contract to the access point 20, and the access point 20 transmits the result value to the corresponding sharer terminal send to

When such an authentication and encryption process is completed, a communication channel is formed between the access point 20 and the corresponding sharer terminal, so data is shared through encrypted communication between the access point 20 and the sharer terminal.

After that, the encryption participants can receive virtual currency in response to the encryption process.

As described above, when any one sharer terminal requests connection to the access point 20, a smart contract is triggered on the blockchain of the network 10, and the sharer terminal, access point 20, and encryption Asymmetric key exchange is performed between the servers 60 . The above-described smart contract is disclosed and stored on a block chain in the form of a code and propagated among users of the network 10, thereby preventing forgery and alteration. The above-described smart contract may include, for example, at least one of a virtual currency issuance condition, a transaction condition, a data sharing process, an encryption process, a proxy process, and an advertisement process.

At this time, the encryption server 60 may receive virtual currency in proportion to the number of encryptions. By using the most secure EAP protocol on the wireless Internet network, users can be safe from security risks on the wireless network.

1, a proxy server 70 allows a terminal (eg, one of an AP sharer terminal 30, a mobile communication sharer terminal 40, and an Internet relay sharer terminal 50) to indirectly access other network services through itself. allows you to The proxy server 70 may be referred to as a server that serves to relay data. For example, the proxy server 70 may store data once requested on the Internet in a large-capacity disk and provide the data stored in the disk when repeated requests are made. That is, when the proxy server 70 receives a request for information retrieval of a certain Internet address from a client, it finds the address in the memory previously read and stored, finds the information immediately if it exists, and brings it from the server at that address if it does not exist. After storing it in memory, it is sent to the client. In this way, since the proxy has memory, a host that many people enter already has data in memory, so it takes it directly from the proxy and delivers it to the requestor. As a result, the traffic of overseas lines is reduced and the speed is also increased.

The proxy server 70 may receive virtual currency in response to the amount of relayed data (eg, data packet amount, time, etc.).

A plurality of proxy servers 70 in FIG. 1 may exist.

If necessary, a virtual private network (VPN) server may be used instead of the proxy server 70 . The virtual private network server registers its public key in the block chain of the network 10 through an authentication procedure, and upon receiving a request to use the virtual private network server from another sharer, it forms an encrypted tunnel through its public key. Safely acts as all network traffic of the sharer.

Accordingly, the virtual private network server may receive virtual currency in response to the amount of proxy data. In particular, when accessing an unreliable network, such as abroad, Internet users can safely use the Internet through a virtual private network server.

Accordingly, the proxy server 70 may register its public key in the block chain of the network 10 through an authentication procedure, as in a virtual private network server. Also, when the proxy server 70 receives a proxy server use request from another sharer, it can safely relay all network traffic of the sharer by forming an encrypted tunnel through its own public key.

In FIG. 1 , the advertiser terminal 80 may request (request) advertisement execution to the advertisement execution server 90 on the network 10 .

At this time, the advertiser terminal 80 may request advertisement execution for all terminals on the network 10, or may selectively designate and request advertisement execution for several terminals. That is, targeting advertisements can be performed based on precise information such as the location, age, interests, and the like of the target sharer, and the number of advertisements published can be limited.

In addition, the advertiser terminal 80 provides predetermined coins (virtual currency) while requesting the advertisement execution server 90 to execute advertisements.

In FIG. 1 , an advertisement publishing server 90 publishes an advertisement to sharers on the network 10 (ie, users connected to the network 10) based on an advertisement publishing request from an advertiser terminal 80.

And, when the advertisement is published, the account of the advertisement execution server 90 and/or the terminal of the sharer who viewed the advertisement will be treated as an increase in a predetermined amount of virtual money.

In Figure 1, the relay server 100 does not necessarily need to exist.

The relay server 100 has a blockchain that the aforementioned terminals have. Accordingly, the relay server 100 may provide a block chain when there is a request from the terminal.

In other words, when using the relay server 100 together, the terminals do not necessarily have a block chain. That is, if some terminals and the relay server 100 have a block chain without the need for all terminals to have a block chain on the network, the terminal that does not have a block chain requests the relay server 100 whenever necessary to block the block chain. You can check the chain.
