※ \Corona Traffic Safety\ uses \homomorphic password\ to prevent anyone from knowing the user's movement information. Compare with information.
※ Based on confirmed case data across the country, contact with confirmed cases is examined.
With \Corona Traffic Safety\, users can check if they are at risk of contact with a confirmed COVID-19 patient. Use the 'Check for contact risks' feature to check for contact risks. The user's visit location and the confirmed person's visit location are compared to determine the contact risk.
Corona Dongseon Relief is special to safely protect personal information using homomorphic encryption. The user's movement information is safely protected so that no one can know it by using homomorphic encryption, the safest 4th generation encryption technology that currently exists. Thanks to the feature of homomorphic encryption that calculations can be performed in an encrypted state, the user's location information cannot be verified even on the service provider's side.
(For a detailed explanation of homomorphic encryption, see
