with some care and the right use of technology, we can safeguard ourselves from these cyber tools. First of all, one should never download any random content online, you should only download any software from authentic websites and after inspecting it carefully. Secondly, if you happen to be an internet geek and most of your personal and professional time is spent there, then you can get yourself anti-malware software installed in your system.
The healthcare sector recognises the work needed to establish a digital infrastructure that builds trust in patients, particularly medical tourists, and exemplifies safety, both physically and digitally.
One of these areas in the digital structure is a system of digital passports which provide proof of vaccination against Covid-19.
Blockchain technology would be an ideal solution to implement such a system, especially a decentralised blockchain ledger, which would provide anonymity, immutability and more importantly, transparency.
Most people have heard about blockchain in association with cryptocurrencies like bitcoin. Blockchain technology is believed to be one of the most secure information storage systems currently in existence. The system comprises a publicly distributed ledger that keeps a record of every transaction in millions of separate blocks called ‘nodes’. Therefore, even if one node comes under attack, the information contained in other nodes will stay secure.
To hack into a blockchain-protected system, the threat actors would need to leverage enormous computing power to compromise millions of nodes at the same time. Precisely because of this, blockchain emerges as an ideal solution to store, safely and securely, all the transaction-related information.
