Amid the pandemic of COVID-19 around the world, new technologies began to be used to monitor the progress of the virus. Frankfurt Airport, for example, has started to adopt blockchain in biovigilance to protect public data and the privacy of those on the move.
The information was confirmed by the Cointelegraph after a Twitter user stated that the airport appeared to be using IOTA blockchain technology to store and manage passenger test and statistical data. The idea is to create a kind of “health passport” to deal with restrictions.
Ubrich provides airport IT solution
Ubirch, a company providing cybersecurity technology, developed the so-called “Digital Certificate Corona Test”, an IT solution that checks the status of passenger SARS-CoV-2 and protects personal data according to European rules. These services are being used by the Centogene Coronavirus Test Center at Frankfurt Airport.
As the company informed the Cointelegraph, the presented technology allows to fix “anonymous fingerprints in blockchain network”. With this, each airline can check the status of the passenger’s SARS-CoV-2 certificate directly at the departure gate, arrival and other airport entrances. Personal user data or test results are protected and not visible.
IOTA technology is used to verify tests
IOTA is an open-source distributed database technology and is used in part by Ubirch for services to Frankfurt airport. According to the company, this makes the results of coronavirus tests verifiable on the network.
Unlike conventional blockchain technology, the IOTA foundation does not effectively use data ‘blocks’. It operates based on a topologically ordered system in which multiple types of transactions are executed in different chains on the network simultaneously.
Blockchain is applied in China and Macau
Blockchain technology has also allowed 17 million people to move between Macau and China’s Guangdong province. As reported by the South China Morning Post, Chinese health officials need to verify information from passengers crossing the border, but just like in Europe, there should be no direct exchange of data for the protocol to remain within the country’s privacy legislation.
Therefore, the Chinese health system uses blockchain technology to encrypt the identification and other personal and health information of travelers, all stored on a network and accessed only by authorized personnel. This allowed authorities in China and Macau to check the viral status of passengers and even whether they had contact with cases of COVID-19 known to the system.
