At the beginning of the pandemic The increasing need for various bio-monitoring measures aroused interest in data protection-enhancing technologies such as blockchainthat could protect public health data in the midst of a crisis.
A single Twitter user he claimed last week what Frankfurt Airport’s coronavirus test center appeared to be using IOTA’s blockchain technology to manage passenger health statisticsand this fact has now been confirmed to Cointelegraph by the technology provider.
Ubirch, a blockchain-based cybersecurity technology provider based in Cologne and several other locations, developed an IT infrastructure for a solution called “Digital Crown Test Certificate”. The solution supports checking the SARS-CoV-2 status of a person and at the same time complies with the European data protection standards of the GDPR. A representative from Ubirch stated:
“Ubrich anchors an anonymous fingerprint in a blockchain network. In this way, the SARS-CoV-2-certified status of a person can be easily checked by the airline at the departure gate, at the arrival airport or anywhere else. Entry point, scanning a QR code. Es It is important to know that at no point during the process are personal user data or test results visible in the network. “
The Ubirch service is used in the Centogene Corona test center at Frankfurt Airportthe company confirmed the underlying technology of IOTA and partially uses it:
“Among other things, we use IOTA to make coronavirus test results verifiable […] We have been working with IOTA for some time. Our public anchors are in Tangle for broad trust. In fact, we’re putting trust anchors in multiple blockchain networks. ”
Ubirch’s reference to Tangle refers to the specificity of the IOTA protocol. Strictly speaking, Tangle differs from other blockchains. since it doesn’t use “blocks” or mining, but based on a directed acyclic graph: A topologically ordered system in which different types of transactions are carried out simultaneously in different chains on the network.
Digital identity solution providers have increasingly developed various products using blockchain designed for use during the pandemic.along with special blockchain applications to offer countries solutions that resemble a “health passport” to ease restrictions.
However, Some security professionals remain concerned about these new “proof of health” solutions and the complexities and challenges of truly ensuring the integrity of the sensitive health data of millions of users.
