The IOTA DAG (Direct Acyclic Graph) is used by Frankfurt Airport to securely and confidentially validate passenger COVID-19 findings.
COVID-19 continues to wreak havoc on our lives for the rest of the year, if not longer. Fortunately, new technologies are surfacing that are speeding up the return to some semblance of normalcy.
Many people crave extended amount of time outside their four walls. This after confinement to their homes for long periods of time. Allowing passengers to just squeeze back into planes, will put even more strain on already overburdened healthcare systems.
Cologne-based cybersecurity technology vendor Ubirch established Digital Corona Test Certificate. The IOTA solution employed at Frankfurt Airport.
UBIRCH is a digital data proofing system that adds security to data-driven processes while also building confidence among numerous stakeholders. A single cloud-based Proof Machine that allows everyone involved to confirm the data’s validity and integrity.
UBIRCH’s Abilities
UBIRCH combines powerful cryptography and modern blockchain technology into an innovative, easy-to-use SaaS platform. Seasoned specialists in cryptography, blockchain, and data-driven business models founded UBIRCH.
Because Europe has severe data restrictions, any solution that operates on the continent must comply. The Digital Corona Test Certificate certifies an individual’s COVID-19 status while adhering to GDPR and other similar requirements in Europe.
According to an Ubirch spokesman, Ubrich uses a blockchain to store an anonymous digital fingerprint. The airline can simply verify an individual’s certified SARS-CoV-2 status at the departure gate. It can also be at arriving airport, or any other entrance point by scanning a QR Code.
He went on to emphasize that it’s crucial to understand that no person-specific user data or test results are available in the blockchain. This would be at any time during the process.
DAGs as Blockchains for Convenience
DAGs are often referred to as blockchains for convenience. However, they are fundamentally distinct while sharing qualities like immutability and decentralization. However, previous difficulties with blockchains, such as scalability and/or high fees, must address.
IOTA has criticisms in the past for too much centralization due to the IOTA Foundation’s deployment of a ‘Coordinator’ node. The coordinator will remove in an impending event known as ‘Coordicide,’ allowing for significantly more decentralization.
Frankfurt Airport clearly feels that its IOTA-based solution will allow for a safe return to flights. People can only hope that it will help alleviate the pressures on people’s lives until vaccines reach a large enough number of people to eliminate limitations.
Frankfurt Airport is a significant international airport in Frankfurt. It is Germany’s fifth-largest city and one of the world’s most important financial hubs.
