A Korean tourist island requires the use of a blockchain application to prevent COVID-19

Jeju Island, an island in the south of South Korea, is one of the most popular tourist destinations for Koreans and receives about 15 million visitors a year.

It now requires these visitors to use an application based on decentralized identity blockchain (DID) technology that aims to provide private and secure COVID-19 contact tracking. An August 19 announcement said that Jeju province had reached an agreement with South Korea’s blockchain company ICONLOOP to introduce the system.

Starting this week, visitors will have to download the Zzeung mobile application when they arrive on the island and verify their identity using a Korean telecommunication service. A verifiable badge will be issued in the backend through a public blockchain network to ensure that no information is forged or tampered with.

Zzeung was designated as an innovative financial service (‚MyID‘) by the Korea Financial Services Commission in recognition of its convenience and security. Jeju is sometimes referred to as „Bit Island“ because of its adoption of technology, in particular blockchain.

Privacy guaranteed (until a case is discovered)
Visitors will need to set up fingerprint authentication or a PIN code to be stored in a private blockchain network. The personally identifiable information of each visitor and the records of the places they visit are separated to ensure personal privacy. Data is kept private unless a case of COVID-19 is discovered.

„Through this new infectious disease prevention system, Jeju Island will be able to reborn as a safe and representative tourist destination in Korea.
