Application of blockchain technology in health management
what is centralization
the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent
the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers
the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high
at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know
so, in which fields can blockchain be applied, what kind of changes will it bring to our future life
the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud
core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people
Application:
1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment
2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute
3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city
4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords
in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.
A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare
First, in the field of finance,
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Second, the Internet of things and logisticsblockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management
Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
the application of blockchain technology in the medical field can be divided into these aspects: electronic health cases, DNA wallet, drug anti-counterfeiting and protein folding. In the future, jinwowo network technology will continue to tap the value of blockchain technology in the commercial field.
at present, Tencent, a domestic Internet giant, has entered the field of blockchain health data. On April 13, Tencent officially released wechat smart hospital 3.0. The new version of wechat smart hospital integrates all medical information into the blockchain, which is supervised on the real-time chain and traceable in the whole process.
① a very important component of "network routing" blockchain system structure is a peer-to-peer network without centralized server. The specific advantage of blockchain technology in the medical field is that hospitals no longer need to establish a centralized patient information management service platform, Centralization of the flat, then very bad thing, once the network "stuck, delay" the whole hospital patient management system will run slowly, but also affect the efficiency of the whole treatment
② the use of blockchain technology can better deal with the speed of seeing a doctor and solve the financial problems of many patients, and "easy financing" is a good example.
take the PPT big health protection ecological platform on the market as an example:
five applications of blockchain in the medical field:
1. In the aspect of EHR medical treatment, the main application of blockchain is the preservation of personal medical records, which can be understood as the electronic medical records on the blockchain. If you think of the medical record as an account book, originally it is in the hands of various hospitals, and the patients themselves do not master it, so the patients have no way to obtain their own medical records and historical information, which will cause great trouble for the patients to seek medical treatment, because the doctors can not fully understand your medical records. But now, if we can use blockchain technology to save, there will be historical data of personal medical care. Whether we see a doctor or plan for our own health, there will be historical data to use. The real master of this data is the patient himself, not a hospital or a third-party organization
2. DNA wallet gene and medical data can be safely stored by using blockchain technology and obtained by using private key, which will form a DNA wallet. This enables healthcare providers to share and count patient data safely, and helps pharmaceutical companies develop drugs more efficiently. And this model is graally being established
3. The development of bitcoin payment blockchain technology promotes bitcoin payment and gives patients more choices for insurance payment. Although it also depends on the development of bitcoin in the market, the insurance companies that provide this way also have greater advantages than their competitors. For health insurance companies, blockchain is being established as a part of financial services
4. Drug anti-counterfeiting is similar to coding anti-counterfeiting technology. For drugs using blockchain technology, there is a scraped surface on the surface of drug packaging box, and a special verification label under it, which is compared with blockchain technology to ensure the legitimacy of drugs
5. Protein folding e to the rapid process of protein folding, Stanford University previously relied on very expensive supercomputers to simulate the protein folding process. This approach is obviously expensive and has a single point of failure. By using blockchain, they can choose to use a huge distributed network for high-speed computing. This example will greatly attract other companies that use expensive supercomputers. With the development of medical technology, medical data is playing a more and more important role in the aspects of patient identity background, past medical history, and medical payment records. Medical data may be a person's most private data, but e to network operation errors or hacker attacks and other problems, in the past, these personal privacy data were leaked on a large scale. For example, anthem once leaked 80 million patient and employee records, and UCLA health once leaked 4.5 million patient data. The medical convenience brought by blockchain includes: as more and more health and preventive care are provided in a virtual environment, such as at home, at work and so on. Open and viable tracking, validation, and care delivery will become very important for patients, payers, suppliers, scientists, and regulators. The development of these new ohh blockchains in the clinical community will prepare for the study of patients' behavior, and for the important data access of supplier reimbursement, rule compliance, security monitoring and patient compliance in the future. Blockchain is a near perfect technology (not necessarily implemented at present). It can easily and safely access ooh data while protecting the maximum privacy, and rece the interest risk of all patients, including patients themselves, families, caregivers, clinics, suppliers, insurance companies and all stakeholders related to patients' health.
the decentralization of blockchain, point-to-point link, openness and transparency, tamper proof, autonomy of smart contract, anonymity and confidentiality can alleviate the problems faced by the medical insurance instry to a certain extent
the decentralized route of blockchain and insurance are in essence consistent. Mutual insurance is essentially a point-to-point transaction. At present, insurance institutions can ecate and sell patients. At the same time, the application of new technology also depends on the insurance institutions themselves.
The development of blockchain has been booming. What are the application areas of blockchain
at present, the most extensive and successful application of blockchain technology is digital currency represented by bitcoin. In recent years, digital currency has developed rapidly. Due to the characteristics of decentralized credit and frequent transactions, it has high transaction value and can maintain a relatively stable price by developing hedging financial derivatives as quasi super sovereign currency
