Global Trends and Strategic Insights into Digital Identity and Self-Sovereign Identity Technology

This paper analyzes the development status of mobile identity cards and self-sovereign identity (DID) technology both domestically and internationally, and examines case studies from major countries that have implemented these technologies. It reviews the adoption status of mobile identity cards in South Korea, including use cases in both the public and private sectors, and compares these with digital identity policies and applications in key countries worldwide, including the EU, the United States, Australia, and Asia. The paper also explores the multifaceted impact of digital identity and DID technology on the reliability, universality, convenience, and security of identification services that are based on alternatives to the national resident registration number. Consequently, this study proposes strategies for the stable implementation of digital identity and DID technology for authentication services.
