Research on Digital Identity Technology and Application Based on Identification Code and Trusted Account Blockchain fusion

Abstract

Digital identity is one of the key elements to build a trust system in the digital economy era. Digital identity has empowered social governance and public services in the new era in many fields, and promoted the rapid development of digital economy. In this paper, a trusted digital identity based on identification code and trusted account blockchain fusion is proposed. Through the unified standard, unified coding identifier, combined with identity-based cryptographic algorithm and blockchain, identification code and trusted account blockchain fusion is realized, and a real, effective, safe and credible digital identity technology system is constructed. Trusted digital identity is a bridge connecting the virtual world and the physical world. It plays a strong supporting role in realizing the identity fusion and ‘digital twin’ of the physical world offline and the virtual world. It is the core element of the construction of new smart cities and the development of digital economy.
