A web application based on blockchain is increasingly becoming a novel paradigm for healthcare security. It provides inconceivable levels of data protection and interoperability, coupled with a tamper-proof record-keeping feature, to solve the primary security issues facing healthcare system actors and integrate data-sharing solutions that allow research stakeholders to collaborate effectively in the healthcare sector.
Understanding Blockchain Technology
What is Blockchain?
Picture this: A memo that belongs to millions of computers and is locked and secured by all the computers as well. That’s blockchain technology in healthcare—a unique system in which every piece of information is locked into unbreakable chains, making it perfect for patient data security and electronic health records management.
Decentralization
In blockchain for healthcare security, no single organization controls the entire system. However, a network of computers keeps and checks all records.
- Every network performer has an absolute copy of all the records, resulting in a multiple-level backup.
- Other parts of the system operate effectively even if one of them is out of order.
- A single participant cannot alter them; rather, they are altered with the permission of several participants.
Immutability
Once information enters a blockchain in the healthcare industry, it becomes permanent and unchangeable, like writing in permanent ink that can’t be erased.
- Each new experience is documented as a new posting, but no change is overwritten in order to maintain the whole story.
- It also means that once records have been created, they cannot be changed or even destroyed.
- Every change is logged, which ensures there is a good audit trail.
Transparency
- Blockchain patient data protection combines privacy with transparency. Authorized participants can access the entire history of records while maintaining security.
- Every participant who is authorized receives the same information at the same time.
- All the permitted users can see any transition to a new setup at once.
- There is a complete file of who has done what and when to what
Cryptography
Healthcare data encryption in blockchain uses advanced mathematical techniques to protect information, similar to having an unbreakable secret code.
- Every piece of data is encrypted with its digital security key.
- Information can only be retrieved by individuals with the relevant keys, and not everyone is issued these keys.
- One of the reasons is that the method of encryption makes it nearly impossible to hack or even change data.
How Blockchain Works
Blocks and Chains
Think of blockchain for secure data exchange as building with digital Legos, where each block contains essential healthcare information.
- All the blocks consist of one or more encrypted records or transactions.
- In a nutshell, every block links the previous one, harmonizing through a code.
- They create an ironclad link across the countries.
- Such a system is evident since trying to change one block is possible only if the entire chain is to be disrupted.
Consensus Mechanisms
For blockchain use in healthcare, special rules ensure everyone agrees on what information is correct.
- If the network receives new information, it must thoroughly authenticate it.
- Many computers verify and validate various transactions.
- Important to recognize that many strategies can be used to achieve that.
- The system only allows the input of information when most entities are in sync.
Smart Contracts
Blockchain development companies have their own computer programs called smart contracts that can perform healthcare tasks as soon as a specific condition is met.
- Adhering to privacy and security regulations mechanically.
- Perform functions to which pre-determined instructions were provided.
- Minimize mistakes and increase the effectiveness of the work.
- Promote standard compliance in delivering healthcare.
Types of Blockchains
Public blockchains
Public blockchains are similar to a public reference library. Anyone can register and contribute towards data management, while the content of data is private and encoded. These systems are fully opulent and do not hold any secret.
Private blockchains
Private blockchains work more like hospital records. They can only be accessed by officials with permission to update them, making them ideal for cybersecurity in healthcare applications.
Public Vs. Private Blockchain
| Parameter | Public Blockchain | Private Blockchain |
|---|---|---|
| Access | Open to everyone | Restricted to authorized users |
| Speed | Generally slower | Faster transactions |
| Security | Highly secure through mass participation | Secure through controlled access |
| Cost | Higher due to an extensive network | More cost-efficient |
| Control | No central authority | Controlled by organization |
The Need for Security in Healthcare
The Sensitive Nature of Healthcare Data
Patient Data
Patient information belongs to the patient and may only be used by practitioners for patient management. Instead, hackers are attacking electronic health records (EHRs) for physical and mental health information, as well as genetic, financial, and social security numbers.
These sensitive digital records can be utilized against the population during wartime. However, the emergence of blockchain in healthcare applications promises to be formidable against such cyber threats.
