Publication number: 20230275762Abstract: The present disclosure relates to a DID system and a method, using browser-based security PIN authentication, which can perform DID identity verification on a browser even though a program for the user's identity verification is not installed or is not used, thereby solving the problem of compatibility between programs. The DID system and method can easily obtain credentials through the cloud server even in using a browser in which the credentials are not stored, thereby simplifying the identity verification procedure. When there is a request for identity verification while using the browser in which the credentials are not stored, the present invention can provide a new control method capable of performing identity verification even if there is no cloud server since performing identity verification by utilizing the browser in which the credentials are stored or by loading the credentials from the browser in which the credentials are stored.Type: ApplicationFiled: May 9, 2023Publication date: August 31, 2023Applicant: SWEMPIRE CO., LTD.Inventor: Myoung Soo CHOI
