Identity includes multiple dimensions such as culture, society, region, psychology, politics, and belief. Identity is the definition of a person by the country or society. This definition will accompany people from birth to death. Everyone has an identity after birth. The concept given by this identity has two meanings, one is the identity given to citizens by the state; the other is the identity of the social class that people discuss.

After the popularization of the Internet, digital identities, user-centric identities and autonomous sovereign identities followed. The most identifying identities, such as mailboxes, represent a person behind the email address, which can help determine a person’s identity. Or today’s Weibo, WeChat, and QQ are all user-centric identities and can be linked to each other. I personally feel that they cannot be separated.

With the development of the Internet nowadays, the usernames and passwords of all online accounts, your search history, social media posts, digital photos, scanned passport pictures, etc. They are all tied to your digital identity and linked to you. Only an email address is required to store your digital identity. Signing in will associate your IP address with the email, so you can pinpoint your location. Digital identities can contain a lot of terrible information. On one level, it includes every photo you have taken, social media posts, and blog comments. So it is difficult for people to control their digital identities to be fully protected while on social media.

Digital identity implements customized services for service providers in public networks. The existence of a digital identity system can effectively replace the complicated paper certificates in the past, reduce the cost of repeated communication between service providers and users, and greatly improve work efficiency. And the government communicates with citizens more efficiently. The digital identity records all citizens’ key identity data and behavioral information. In the face of citizens with different attributes and their needs, the government can provide corresponding assistance to them.

The development of the Internet and the emergence of digital identities are changing the driving force and development methods of economic and social development. Compared with traditional identity systems, they will greatly improve overall social efficiency.
