IOTA blockchain used to trace COVID-19 check outcomes at Frankfurt Airport



Early on within the pandemic, the heightened want for numerous biosurveillance measures sparked curiosity within the relevance of privacy-enhancing applied sciences corresponding to blockchain that might shield public well being information amid the disaster. 

A person Twitter consumer claimed final week that Frankfurt Airport’s Corona testing heart gave the impression to be utilizing IOTA blockchain expertise to handle passengers’ well being stat, and this reality has now been confirmed to Cointelegraph by the expertise supplier.

Ubirch, a blockchain-based cybersecurity expertise supplier primarily based in Cologne and several other different places, has developed the IT infrastructure for an answer it calls the “Digital Corona Take a look at Certificates.” The answer helps verification of a person’s SARS-CoV-2 standing whereas remaining compliant with European information safety requirements underneath the GDPR framework. An Ubirch consultant defined:

“Ubrich anchors an nameless digital fingerprint in a blockchain. This manner, a person’s licensed SARS-CoV-2 standing can simply be verified by the airline on the departure gate, the arrival airport, or every other entry level by scanning a QR Code. Vital to know is that at no level throughout the course of are person-specific consumer information or check outcomes seen within the blockchain.”

The Ubirch service is getting used on the Centogene Corona check heart at Frankfurt Airport, the corporate has confirmed, and makes use of, partly, underlying expertise from IOTA:  

“Amongst others we use IOTA for making the Corona check outcomes verifiable […] We’re working with IOTA for some time now. Our public anchors are in the principle tangle for broad belief. The truth is, we put belief anchors in a number of blockchains.” 

Ubirch’s reference to “the principle tangle” refers back to the particular character of the IOTA protocol. Tangle is, strictly talking, completely different from blockchain in that it doesn’t use “blocks” or mining, however is constructed upon a directed acyclic graph: a topologically ordered system during which various kinds of transactions run on completely different chains within the community concurrently.

Digital id resolution suppliers have more and more developed numerous merchandise involving blockchain which might be focused to be used throughout the pandemic, alongside particular blockchain apps to offer international locations with “well being passport”-like options for alleviating restrictions. 

Some safety consultants stay involved, nevertheless, about these rising “proof-of-health” options and the complexities and challenges concerned in actually guaranteeing the integrity of hundreds of thousands of customers’ delicate well being information.
