Blockchain in the Medical field of India
Blockchain or digital ledger is the safe recording of information that is almost impossible to hack. A brief introduction to the role of blockchain in the medical industry in cybersecurity is discussed in this article. Hope it helps in the process of understanding blockchain.
In particular, Blockchain works on the concept of digital ledger technology where decentralization of data is the key concept.
Other than that, The blockchain in medical fields can be used to record patients’ details, treatment, medicines, etc. in huge numbers with cybersecurity.
India has a vast diversity with over 130 crore population. It definitely needs a system like a blockchain. Already many countries in the world have established this facility for their people and it is successful.
India needs a sophisticated medical recording and maintaining system, available for access at times of emergency.
How does blockchain works
The blockchain’s constituents are blocks. These blocks contain the data stored on nodes. Also, The full information of the transaction is stored in each node of the database. Here computer servers act as nodes. The stored information is almost unchangeable.
Furthermore, These blocks are preserved by a unique signature called hash which cannot be changed or removed without the permission of previous blocks.
To illustrate, let us consider a hacker trying to change any detail of the transaction. Because of this the signature or hash mismatches. Immediately each user will be notified about the hack.
Bitcoins or digital money works on the basis of blockchain.
Types of blockchain
- Public-100percent transparent with no restrictions
- Private -data sharing is among limited or specific participants
- Permissioned– It is a mixture of public and private types.
- Sidechains– this runs in parallel to the blockchain. Moreover, The user can access information directly from the side chain, without disturbing the main chain.
India’s first ever blockchain for medical purpose
Call health is the world’s first and genuinely integrated healthcare platform. It has partnered with Thynkblynk. Whereas it is the developers of ChainTrail, ensure healthcare data integration in India. In addition, This is the first time in India where there is a partnership in March 2019. Further, It is between blockchain services and healthcare services platform.
Advantages of blockchain
The advantages in medical industry include reducing
- Drug piracy
- Frauds on insurance claim
- Other severe information crimes
The Ayushman Bharat Pradhan Mantri yojana aims at free medical aid to 40% of the Indian population. At least, It is 50 crore people. Therefore, this scheme is the world’s largest government health care program.
- Indeed for such an initiative blockchain and DLT concepts are a boon. Consequently, It is possible to maintain the health records of the people who benefitted through this government scheme.
Limitations of blockchain
- Firstly, Blockchain needs high computing power to keep the transaction data encrypted. Multiple servers across different geographic locations around India are required for blockchains.
- Secondly, Limited customization options and stubborn mechanism. It cannot be altered to fit the requirements of the industry.
- Thirdly, It is a very new concept. We are yet to see its robustness and usability across a huge population’s record trafficking.
Technological advancements like Block chain are a boon where cyber crimes are high in;
- Internet fraudulent
- Financial abuse
- Misuse of personal information etc.
- There are successful results in many countries on using them. Above all, India has also started to incorporate them in medical and other fields. Specifically, security and safety are unavoidable.
