What can Blockchain offer for Cyber Security?

Healthcare Tech Outlook | Friday, November 30, 2018

We all will agree that blockchain is one of most emerging technologies today with many tech-savvy leaders eyeing to leverage its potential benefits. Albeit the technology has found extensive usage in financial institutions, lately many of the leading cybersecurity companies are using blockchain to prevent malicious data tampering. Blockchain will assist organizations to create a safer network communication culture through eradicating the security problems faced on the web.


Understanding Blockchain Dynamics

In a nutshell, blockchain can be defined as a decentralized public ledger technology that facilitates the flow of digital currency and maintains a trusted transaction network without the interference of any central authority. Here, every transaction gets recorded and added to blockchain and whoever participates in the process receives a transaction copy. The noteworthy thing of the chain is that it has a unique method to verify transactions and also has the ability to digitalize, code, and store any document which can be very beneficial for cybersecurity. 

Blockchain in Healthcare 

Primarily, with blockchain architecture, a healthcare system can be built where each patient will have accurate and updated records that are kept against tampering or spying. The recorded data can be shared promptly and feasibly with any concerned persons. The electronic health record (EHR) stores all the key medical history of patients and includes administrative, clinical data pertinent to each person’s treatment. This data can be related to anything such as progress diagrams, potential problems, medications, immunizations, past medical history, and laboratory data.

Furthermore, it also has the capability to access information and streamline clinicians’ workflows. On the other hand, the disadvantage associated with EMR is that patient information is not regularly updated, and insecure data storage paves the way for cybercrime. To this end, blockchain can assist healthcare institutes to keep data secure for years and further eradicate and track human errors. Here, patients can also review and update information by making new entries. The most contrasting factor of blockchain over EMR is that here information is safe and secure, which makes hacking and fraud extremely difficult.
