Description

Method and server for collecting patient medical information based on blockchain {METHOD AND SERVER COLLECTING MEDICAL INFORMATION OF PATIENT BASED ON BLOACKCHAIN}

The present invention relates to a method and server for collecting patient medical information based on blockchain.

In most cases, emergency treatment performed in an emergency room only considers the emergency situation that has occurred and does not consider the patient's medical information. In addition, even if you try to provide emergency treatment by considering the patient's medical information, if the patient has not received treatment at the hospital, the medical information cannot be used and a new medical chart must be created. If emergency treatment is performed in a situation where the patient's medical information is not considered, there is a high risk that unexpected side effects may occur in the patient due to the emergency treatment.

Figure 1 shows an example of a communication structure between a server and a user device.

In this specification, “server” is a type of server that communicates with external devices (e.g., user devices) or external servers (other than itself) through a network, and operates external devices or external servers. It can represent a server for In one example, the server may be implemented using general server hardware and a web server program that is provided in various operating systems such as DOS, Windows, Linux, Unix, and Macintosh. Alternatively, in one example, the server may be the same or similar device as the user device described below. In one example, the server may be an emergency room dashboard system or an emergency room dashboard server.

In one embodiment, the server 110 may refer to a device that collects a patient's medical information based on blockchain. For example, the server 110 may be referred to by various names, such as an operation server, medical information management server, medical service platform, medical server, and medical service-blockchain mediation server.

In this specification, “user device” includes smartphones, cell phones, smart TVs, smart watches, electronic wristwatches, set-top boxes, PCs, tablet PCs, digital cameras, camcorders, laptop computers, and desktops. , e-readers, digital broadcasting terminals, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), navigation, MP3 players, wearable devices, air conditioners, microwave ovens, audio, DVD players, etc. It can be implemented as a device.

In this specification, the server 110 and the user device 120 may communicate with each other through a communication network. The communication network may be, for example, a wireless communication network or a wired communication network. The wireless communication network may be, for example, a communication network based on Long Term Evolution (LTE) Radio Access Technology (RAT), New Radio (NR) RAT, WiFi, etc.

In one example, the server 110 and the user device 120 may perform device-to-device (D2D) communication with each other and perform UU communication with a base station (e.g., gNB and/or eNB). can do. In time division multiple access (TDMA) and frequency division multiple access (FDMA) systems for performing the D2D communication or the UU communication, accurate time and frequency synchronization may be required. If time and frequency synchronization is not accurate, system performance may deteriorate due to inter-symbol interference (ISI) and inter-carrier interference (ICI). In D2D communication according to one example, for time/frequency synchronization, a synchronization signal may be used in the physical layer, and a master information block (MIB) may be used in the radio link control (RLC) layer.

In the D2D communication process, the server 110 and the user device 120 are synchronized directly to GNSS (global navigation satellite systems), or through a terminal (within network coverage or outside network coverage) directly synchronized to GNSS. It can be indirectly synchronized to GNSS. When GNSS is set as the synchronization source, the server 110 and the user device 120 can calculate the DFN and subframe number using Coordinated Universal Time (UTC) and a (pre)set Direct Frame Number (DFN) offset. .

Alternatively, the server 110 and the user device 120 may be synchronized directly to the base station or to another terminal that is time/frequency synchronized to the base station. For example, the base station may be an eNB or gNB. For example, when the server 110 and the user device 120 are within network coverage, the server 110 and the user device 120 receive synchronization information provided by the base station and are directly synchronized to the base station. You can. Afterwards, the server 110 and the user device 120 may provide synchronization information to other adjacent terminals. When the base station timing is set to the synchronization standard, the server 110 and the user device 120 are connected to a cell associated with the frequency (if within cell coverage at the frequency), primary cell, or serving cell for synchronization and downlink measurement. (if outside of cell coverage at said frequency).

A base station (e.g., serving cell) may provide synchronization settings for carriers used for D2D or sidelink (SL) communications. In this case, the server 110 and the user device 120 may follow the synchronization settings received from the base station. If the server 110 and the user device 120 did not detect any cell on the carrier used for the D2D or SL communication and did not receive synchronization settings from the serving cell, the server 110 and the user device 120 120 may follow preset synchronization settings.

Alternatively, the server 110 and the user device 120 may be synchronized to another terminal that does not obtain synchronization information directly or indirectly from a base station or GNSS. Synchronization source and preference can be set in advance to the terminal. Alternatively, the synchronization source and preference can be set through a control message provided by the base station.

In one embodiment, the server 110 and the user device 120 may communicate with each other through a network 100 (or communication network). For example, when the server 110 transmits data to the network 100, the network 100 may deliver (transmit) the data to the user device 120. Alternatively, when the user device 120 transmits data to the network 100, the network 100 may deliver (transmit) the data to the server 110.

In the following description of FIGS. 2 to 7, a method for the server 110 to collect a patient's medical information based on blockchain based on signal exchange or communication between the server 110 and the user device 120 will be described. Review this in detail.

Figure 2 is a diagram to explain an example of a blockchain transaction being performed.

Block chain refers to a collection of blocks connected one after another. Here, the block forming the chain may record/include confirmed transaction details transacted over a certain period of time through the corresponding blockchain platform. In order for a block recording pre-confirmation transaction details to be approved, validity judgment must be performed by network participants. An example of the validity judgment method or consensus protocol will be described in detail later in FIG. 3.

Figure 2 shows the communication structure between participants performed within a specific blockchain platform. The first blockchain transaction participation device 210 and the second blockchain transaction participation device 220 may represent user devices of two users performing a blockchain transaction, and one or all of the devices may be a server. You can. For example, each of the first blockchain transaction participation device 210 and the second blockchain transaction participation device 220 may be one of the server 110 or the user device 120 described above in FIG. 1 .

A blockchain platform can refer to a blockchain ecosystem or blockchain network that operates based on proprietary blockchain technology. There are various types of blockchain platforms, such as Bitcoin, Ethereum, Solana, and Klaytn, and each blockchain platform has its own blockchain consensus protocol, interface, and block size. Some of the factors may be different. The transaction method used in each blockchain platform is cryptocurrency. Depending on the consensus protocol adopted by each blockchain platform, the method of creating and trading cryptocurrency may vary. The consensus protocol is detailed in Figure 3. This will be described later. Cryptocurrency may also be referred to as virtual currency, digital asset, digital currency, etc.

In one embodiment, cryptocurrency can be classified into coins and tokens. Coin refers to a cryptocurrency that is not dependent on other platforms and forms an independent ecosystem with its own mainnet. Examples include all platform coins such as Ethereum and EOS. Additionally, even if it is not a platform coin, an independent cryptocurrency that is not dependent on another platform, such as Bitcoin or Ripple, can also be referred to as a coin. Token refers to a cryptocurrency used to achieve an individual purpose on top of other platform coins. In other words, the token does not have its own mainnet and operates based on another platform. For example, Status Network Token (SNT) is a token that operates based on the Ethereum platform (or the next-generation Ethereum platform (e.g., Ethereum 2.0)).

Ethereum is a public blockchain platform created by Vitalik Buterin on July 30, 2015, and represents the name of the platform's native currency (i.e. cryptocurrency). While Bitcoin focuses on payment and transaction-related systems, that is, functions as currency, Ethereum is based on blockchain, a core technology, and is used not only for transactions and payments, but also for contracts, SNS (Social Network Service), email, electronic voting, etc. It can provide scalability so that various applications can be operated transparently. In other words, it is a platform that allows anyone to create and use not only a currency but also an analysis application (Decentralized Application) called dAPP. Ethereum's mainstream programming language is Solidity, a modified version of JavaScript, but it supports most major programming languages such as C++, Java, Python, and Go, providing versatility.

NFT (Non-Fungible Token), or 'non-fungible token', can refer to a blockchain-based token that cannot be exchanged or copied and thus has its own uniqueness and scarcity. As mentioned above, fungible cryptocurrencies such as Bitcoin can be exchanged 1:1 because they each have the same value, whereas NFTs have values and characteristics that cannot be replaced by each being given a unique recognition value. do. By applying NFT technology, which puts a unique serial number on assets that can be digitized, you can create (digital) assets that cannot be copied, that is, only one in the world. Assets to which NFT can be applied include videos, images, sounds, It is very diverse, ranging from digital content such as text to artwork, collectibles, game items, phonemes, various products, virtual real estate, etc.

The plurality of nodes 230 represent a plurality of servers, a plurality of devices, and a plurality of networks involved in the consensus protocol of transactions performed on the specific blockchain platform. In one example, one of the plurality of nodes 230 may be configured based on at least one of a plurality of servers, a plurality of devices, or a plurality of networks. Or, in another example, one node among the plurality of nodes 230 may mean one server, one device, or one network. In one example, the range of the plurality of nodes 230 may be different depending on the type of consensus protocol.

In FIG. 3, the plurality of nodes 230, the first blockchain transaction participation device 210, and the second blockchain transaction participation device 220 are depicted as distinct, but this is to clearly indicate the blockchain transaction participation device. In some embodiments, the plurality of nodes 230 may include the first blockchain transaction participation device 210 and the second blockchain transaction participation device 220. The plurality of nodes 230, the first blockchain transaction participation device 210, and the second blockchain transaction participation device 220 shown in FIG. 2 are connected through the network 100 described above in FIG. 1. Data can be sent and received between them.

A method of transmitting a specific cryptocurrency used within the specific blockchain platform from the first blockchain transaction participation device 210 to the second blockchain transaction participation device 220 according to one embodiment is as follows. The address of the cryptocurrency electronic wallet owned by the first user of the first blockchain transaction participation device 210 (or the first user's blockchain ID, the first user's blockchain public key ( public key), etc.), the quantity of the specific cryptocurrency to be transmitted, and the cryptocurrency electronic wallet to be transmitted (i.e., the address of the cryptocurrency electronic wallet owned by the second user of the second blockchain transaction participation device 220) Participating in the first blockchain transaction using transaction information (or transaction ID) including the address of the second user (or the second user's blockchain ID, the second user's blockchain public key, etc.) When transmitting from the device 210 to the plurality of nodes 230, the plurality of nodes 230 can approve the transaction through a predetermined consensus protocol method. When the transaction is approved, the quantity of the specific cryptocurrency may be transferred from the cryptocurrency electronic wallet owned by the first user to the cryptocurrency electronic wallet owned by the second user. In other words, through the plurality of nodes 230, the specific cryptocurrency is reduced by the amount in the cryptocurrency electronic wallet owned by the first user, and the specific cryptocurrency is reduced by the amount in the cryptocurrency electronic wallet owned by the second user. A block recording an increase in the specific cryptocurrency by the amount can be combined with an existing blockchain within the blockchain platform to form a new blockchain.

A smart contract refers to a digital contract method in which contract conditions are coded based on blockchain technology and the contract is implemented when the conditions are met. The method for the first blockchain transaction participation device 210 and the second blockchain transaction participation device 220 according to an embodiment to conclude a smart contract based on the specific blockchain platform is as follows: same. At this time, either the first blockchain transaction participation device 210 or the second blockchain transaction participation device 220 supports, for example, a Non-Fungible Token (NFT) trading platform such as opensea. It could be a server that does. When the first blockchain transaction participation device 210 requests the plurality of nodes 230 to create a smart contract account, the plurality of nodes 230 create a smart contract account. can do. At this time, the second blockchain transaction participation device 220, which agrees to the contract contents of the smart contract, sends the contract contents to the plurality of nodes 230 and the first user of the first blockchain transaction participation device 210. When transmitting transaction information (or ID) including the cryptocurrency electronic wallet address owned by and the cryptocurrency electronic wallet address owned by the second user of the second blockchain transaction participation device 220, the smart contract is It is concluded so that the contents of the above contract can be realized/executed. For example, the NFT owned by the first user moves from the first user's cryptocurrency electronic wallet to the second user's cryptocurrency electronic wallet, and a certain cryptocurrency owned by the second user is transferred to the second user. It is possible to move from the user's cryptocurrency electronic wallet to the first user's cryptocurrency electronic wallet.

In one embodiment, blockchain transactions between devices participating in the blockchain transaction according to FIG. 2 may be performed in a metaverse environment. Metaverse refers to a virtual space platform that allows users to engage in social, economic, educational, cultural, scientific and technological activities similar to actual reality through an avatar. The metaverse environment can be expressed in a three-dimensional virtual space, but this is only an example. The metaverse environment can be expressed through a two-dimensional flat virtual space, or a four-dimensional virtual space with tactile and olfactory senses.

Multiple users can use/experience/experience the metaverse environment through their respective avatars. For example, within a three-dimensional virtual space within the metaverse, the first avatar performs physical activities such as moving, jumping, sitting, lying down, or exercising, and performs economic activities such as trading with the second avatar. This can be done, and learning can also be performed through images displayed in a 3D virtual space.

In one embodiment, a transaction is made between a first avatar and a second avatar within the metaverse, or a transaction is made between a first avatar and a metaverse server (e.g., a first avatar provides medical care provided by a second avatar within the metaverse). When a transaction is made to view review information, the cryptocurrency of the blockchain platform can be used.

Figure 3 is a diagram to explain examples of methods for verifying blockchain transactions.

Consensus protocol methods by which a plurality of nodes 230 constituting the blockchain platform prove blockchain transactions include, for example, Proof of Work (PoW) 310 and Proof of Stake. PoS) 320 exists, and the types of consensus protocol methods are not limited to the above two.

In the proof-of-work method (310), the block creator (or miner, verifier, etc.) applies a nonce value with random characteristics and a hash algorithm to transaction record information, presented in the block header of the blockchain. It refers to a consensus protocol that creates a block and receives compensation by detecting a hash value that satisfies the difficulty conditions. Block creators can receive compensation, for example, in cryptocurrency used on the blockchain platform. Blockchain platforms that use the proof-of-work method 310 include, for example, Bitcoin and Ethereum. If the consensus protocol method of a specific blockchain platform is the proof-of-work method (310), the object that proves the blockchain transaction within the specific blockchain platform is the block creator (or miner, verifier, etc.), so the plurality of Nodes 230 may refer to the block generator.

The proof-of-stake method 320 refers to a consensus protocol that differentially grants the authority to create blocks to each node depending on the amount of stake of each node in the blockchain platform at the time of agreement. The stake of each node may be proportional to the amount of cryptocurrency held by each node. Each node can receive a reward for the transaction fees generated by the blockchain platform according to the proportion of each node's contribution to block creation. Blockchain platforms that use the proof-of-stake method 320 include, for example, Solana, ADA, and next-generation Ethereum (e.g., Ethereum 2.0). If the consensus protocol method of a specific blockchain platform is the proof-of-stake method (320), the subjects of proving blockchain transactions within the specific blockchain platform are all participants or nodes holding cryptocurrency used in the blockchain platform. Therefore, the plurality of nodes 230 may mean all participants or nodes.
