MISBLOC: Vaccine Passport
Vaccine Passports are the key to getting back to normal!
MISBLOC (Medical Information Service with Blockchain) is a medical service ecosystem which is based on blockchain technology. MISBLOC offers a sustainable and efficient medical service ecosystem by providing reliable medical information to patients, medical institutions, and public institutions in the Big Data era.
Hi there! In today’s post, we would like to provide some insights into the ongoing exploration of the vaccines that are going to end the COVID-19 pandemic. More than that, in order for different industries to return to normal, vaccines will play a huge role. Then, the travel industry will require vaccine passports to be present. What if those passports were fully established on the blockchain?
Vaccine Passports
A vaccine passport is a digital certificate that proves that the passport holder has received the COVID-19 vaccine. Digital certificates and vaccine passports are being issued worldwide with the intention of allowing only those who have been vaccinated to move freely in order to promote overseas traveling.
Vaccine Passports on the Blockchain
The application of blockchain technology has attracted a lot of attention. It would make the vaccine passport impenetrable to data forgery or revision. Since it is a certificate needed for immigration, it is called a “passport,” but in fact, the vaccine passport is an app that runs on a smartphone.
The core function of this app is to indicate the history of the COVID-19 examination and whether or not the holder is vaccinated. Diagnostics and inoculations are also recorded with reliable institutions. “The use of a vaccine passport makes it simple to proceed with entry and exit procedures by compiling the results of national tests that are currently fragmented without standards,” IATA said.
In Israel and China, personal information contained in vaccine passports will be converted into QR codes, stored in smartphone apps, and authenticated when needed. This could lead to forgery or manipulation if it is not encrypted.
In fact, Israel has raised concerns over a surge in crimes against their “Green Pass,” a vaccine passport. The fact that forged certificates are illegally distributed through SNS such as Telegram is hurting these passports’ reliability.
To solve this problem, the Decentralized Identity (DID) system, which operates on blockchain technology, is emerging as a key technology for introducing vaccine passports due to its decentralization.
When blockchain technology is used, the personal information of the issued vaccine passport can be encrypted and stored on a smartphone. Then, only the desired information, such as visas, travel, and flight reservations can be selected and submitted.
Recently, interest in blockchain technology is increasing. Some are also discussing the possibility of using a Non-Fungible Token (NFT) system to make a certificate with blockchain technology to be used as vaccine passports. A direct feature of NFTs is that they are non-replaceable tokens, which means that these digital assets are not interchangeable due to their unique values.
Only time will tell which strategy will be used, but it’s exciting to see blockchain technology being used in such a useful way. It seems that blockchain will continue to go mainstream and more and more industries will embrace this technology.
