Conventional digital authentication employs a centralized architecture, such as domain name and IP (internet protocol) address allocation managed by ICANN (the internet corporation for assignedn numbers), and digital certificates managed by CA (certificate authority) certificate authorities in PKI (public key infrastructure) systems. The essence of the method is that a central authority holds identity data, authentication, authorization and the like performed around the data are determined by the central authority, and the identity is not controlled by a user.
In order to solve the problem of interconnection and intercommunication of identity systems (and data corresponding to accounts) among websites, alliance identities appear. The federation identity includes one or more systems sharing user access rights, allowing a user to log into one system of the federation after the user has completed authentication. Currently, decentralized identity is adopted in alliance to represent alliance identity of each system. Decentralized identity is a new type of identifier with global uniqueness, high availability, resolvability and verifiability of encryption. A decentralized identity is typically associated with the cryptographic material and the service endpoint to establish a secure communication channel.

For example, by means of an identification document or photograph, or to obtain authentication by an authoritative authentication authority. In addition, the user can operate the user agent to generate encrypted material (e.g., public/private key) that can be used for wallet address and subsequent signature verification.

in this step, after receiving the non-homogenization certification to be verified, the user agent end writes the non-homogenization certification to be verified into a verification request, and sends the verification request carrying the non-homogenization certification to the authentication service terminal.
It should be noted that the verification request sent by the user agent further includes a network address for receiving feedback information of the authentication service terminal. In this embodiment, the authentication service terminal needs to obtain the authentication challenge according to the non-homogeneous certification, that is, the network address in the verification request sent by the user agent may be used to receive the network address of the authentication challenge.
Specifically, the authentication service terminal generates a block chain transaction according to the received to-be-verified non-homogenization evidence, activates an intelligent contract on the block chain, and then the authentication service terminal can acquire metadata corresponding to the non-homogenization evidence from the block chain. And the authentication service terminal generates an authentication challenge according to the metadata, wherein the challenge comprises a ciphertext obtained by encrypting the public key in the acquired metadata. The authentication challenge may also contain the network address to be returned in response to the authentication challenge and the authentication service endpoint.
S203: decrypting the ciphertext by using a private key in the metadata corresponding to the non-homogenous certification;
in this step, the user agent receives an authentication challenge fed back by the authentication service terminal. And the user agent terminal decrypts the ciphertext in the authentication challenge by adopting a private key in the metadata corresponding to the non-homogenization certification. And sending the decrypted result to the authentication service terminal through a network address contained in the authentication challenge and returned by responding to the authentication challenge. The authentication service terminal determines whether the authentication challenge is successful.
S204: and sending the decrypted ciphertext to an authentication service terminal so that the authentication service terminal feeds back a verification result.
In this step, the authentication service terminal receives a result of decryption of the ciphertext sent by the user agent, that is, the ciphertext decrypted by the user agent. And the authentication service terminal compares the ciphertext decrypted by the user agent terminal with the ciphertext stored by the authentication service terminal. If the ciphertexts are the same, determining that the authentication challenge is successful; otherwise, it is determined that the authentication challenge failed. And the authentication service terminal feeds back the verification result to the user agent terminal. Namely, the authentication service terminal feeds back the success or failure result of the authentication challenge to the user agent terminal.

The feedback request is sent to the user agent side, which may associate the account with a transaction address or a smart contract address. In addition, the user agent end generates casting transaction information of the non-homogenization certification according to the account and metadata stored in the user agent end locally in advance.
