CNB Journal looks at how DID is already making Korea a better place.
For example, there’s Zzeung, the centerpiece of the ICONLOOP-led MyID Alliance. The DID solution powers Jeju Safety Code, the local contact tracing app of Korea’s insanely popular resort island of Jeju.
From CoinTelegraph:
The Jeju Safety Code allows visitors and tourists to securely check in at public places without risking the loss of personal data. To use the Jeju Safety Code app, visitors scan a QR code at a business or tourist destination. Business owners can place QR codes across their facilities, allowing people to check in without forming a line.
According to the app’s creators, users do not need to sign up for an account to check in. When a visitor checks in, their location is authenticated, without the business needing to store any of their personal information.
Visitor’s personal identifying information and visit records are stored in a private blockchain network. The app uses Iconloop’s decentralized identity, or DID, technology system to ensure that all data is kept private unless a COVID-19 case is discovered. According to Iconloop, the information is only used for the purpose of epidemiological investigation of confirmed cases.
While the Ministry of Health’s KI-Pass electronic entry log solution is ubiquitous, conditions on Jeju limit the app’s effectiveness. The island has a huge fluid population in the form of tourist hordes, and many of the island’s restaurants are too small to afford the devices KI-Pass requires. Jeju Safety Code makes it easier for local small businesses to take part in quarantine efforts.
Last August, Shinhan Bank — Korea’s second largest commercial bank — announced it would issue KYC compliance certificates using Zzeung. This was also the first time a South Korean financial company made commercial use of a DID service.
