What is the Relationship Between Blockchain and Your Medical Treatment?
What is blockchain?
Blockchain is a distributed database. It is exactly the core technology of Bitcoin.
Blockchain is a series of data blocks generated by a cryptographic method. Each data block contains information on a network transaction to verify the validity of its information and generate the next block. In the popular sense, the blockchain is an account book that everyone can record. Of course, blockchain is not a traditional account book. It has the following three key points in technical principles:
In a blockchain technology network, each computer it covers can read and add records. From the perspective of bookkeeping, they are the people who jointly record books, and no authoritative person can guide and correct them.
2. Asymmetric Encryption
Although everyone can record this account, it must be hard to understand if you are not an insider. Because in the process of bookkeeping, everyone follows the uniform encryption rules, but when reading, you must use your own unique decryption way. Therefore, although everyone keeps this constantly updated account, the part that can be read is only the part that can be deciphered, that is, related to yourself.
3. Time stamp
A timestamp is the character string or code information used to recognize the recorded date and time. Each block in the blockchain is arranged in chronological order according to the time it was generated, and it has been collectively certified and confirmed to be valid. Moreover, previous records cannot be modified. Just like in an account, we can index and verify the previous content through a record. Once these contents are confirmed, it will be even harder to tamper with them again.
Due to these characteristics, the core advantages of blockchain technology in application are very significant: the decentralized distributed structure can save a lot of intermediary costs in reality; the timestamp feature that cannot be tampered can solve the problems of data tracking and information security; the security trust mechanism can solve the core defects of the Internet of things technology; flexible programmable features can help regulate the existing market order.
The role of blockchain is to provide trust in an untrusted environment, which is desperately needed in medical industry.
What can Blockchain+Medical do?
Blockchain can break information barriers between different hospitals, decentralize the blockchain database, and realize the linkage of multiple network nodes to achieve data security protection.
1. Electronic medical records（EMR）
When we visit different hospitals, we will be issued different medical records, and those medical records are not interlinked. If the patient does not take the initiative to mention or provide his past medical records in other hospitals, the hospital is unable to obtain it. It will hinder medical treatment to a certain extent.
Using blockchain technology to record personal data and diagnostic records can improve the integrity and privacy of the medical records. When medical records are uploaded to the blockchain, people can check their medical records without going through a third party, and follow the progress and appointment of the entire rehabilitation in time, and the authorized users access mechanism of blockchain guarantees medical records kept safer, protects the privacy of medical records, and makes it more convenient to see a doctor.
For hospitals, they can make medical records accurate and well-preserved, eliminating the misdiagnosis problems caused by mis-recording of data, and saving human resources for processing medical records.
The traceability of blockchain allows it to be used for backtracking, supervision and anti-counterfeiting of pharmaceuticals, giving the unique code of raw materials and finished products, making it impossible for counterfeiters to take advantage of the loopholes, and striking a fatal blow to counterfeit drugs.
3. Payment claims
The blockchain-based transfer payment system features high efficiency, high security, high availability, and high scalability. Using blockchain technology and distributed accounting, each user can check the status of transactions with a password, and the funds can be liquidated in real time, which reduces transaction costs and risks and improves transaction efficiency. It not only promotes the development of cryptocurrency, but also can effectively prevent fraud and other improper acts, and reduce the waste of medical resources.
We still have a long way to go.
For now, blockchain technology is not yet known to the general public, and it is obviously not easy to convince the public to use its principles to apply to the medical industry. We have a long way to go, but we have to hold the belief that over time people will eventually believe that the blockchain can be used to help us manage complex and sensitive medical systems.
