This invention discloses a decentralized
digital identity management method,
system, and device, belonging to the field of
digital identity management technology. The
system includes: a user-end module configured to execute a local trusted
processing method for
digital identity materials; a credential generation
service module, communicatively connected to the user-end module, configured to execute a method for generating verifiable credentials; and a credential
verification service module, communicatively connected to the user-end module, configured to verify verifiable credentials. This application protects data privacy through localized
processing on the
client side, ensures the immutability of credentials through
blockchain storage, and automatically generates verifiable credentials using smart contracts. It achieves minimized disclosure of user identity data, reliable
traceability of sources, and efficient
verification at the
verification end, constructing a secure, reliable, efficient, and user-controllable new paradigm for decentralized digital identity
authentication.
