It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1
A distributed identity authentication method is suitable for a user node and comprises the following steps: initiating a transaction to a blockchain system requesting authentication of a first identity of a user; receiving a first identity authentication declaration sent by a first proving party node and passing authentication; the method comprises the steps that a first proving party requesting for transaction of a first identity of a user to be authenticated is received, the first proving party requests for verification of the first identity of the user to a blockchain system, and if the verification is passed, a first identity authentication statement passing the authentication is sent; the transaction requesting authentication of the first identity of the user comprises a user identity identifier and a first proving party capable of proving the first identity of the user; the user identity identifier is generated on the block chain system according to a public key and a private key of the user and identity information including a first identity; the first authentication assertion comprises a user identity identifier signed by a first proving party.
The user with the identifier locally encrypts all personal identity information and then stores the personal identity information in a distributed mode in a blockchain network or stores the personal identity information in a local mode; and for the first proving party, requesting the block chain system to feed back first identity information corresponding to the user through the user identifier, and issuing a verification statement if the first identity information is consistent with the self-stored information of the first proving party by comparison.
The first identity transaction requesting authentication of the user comprises a user identifier, first identity information to be authenticated of the user and associated with a first proving party, information required to be verified by the first proving party such as the purpose of authenticating the first identity, and feedback time expected by the user (if the system is a traditional network system).
The first proving party may be various organizations having a certain authority and a certain credibility, such as a bank, a school, a business, a government agency, an association organization, and the like.
Specifically, the method comprises the following steps: receiving a transaction requesting authentication of a first identity of a user; requesting verification of a first identity of a user from a blockchain system; if the verification is passed, a first identity authentication statement passing the authentication is sent; wherein the first authentication assertion comprises a user identity identifier signed by a first proving party.
A distributed identity authentication method, adapted to a user node, according to the above described distributed identity authentication method, comprising: sending a first authentication transaction; receiving information whether first identity authentication sent by a first authenticator node passes or not; wherein the first authentication transaction comprises a first authentication statement and a first verifier; a first authenticator node receiving a first authentication transaction; requesting verification of a first authentication assertion from the blockchain system; and if the authentication is passed, sending the first authentication passing information to the user node.
In particular, the first authentication transaction further comprises a validity period of the first authentication transaction. So as to restrict the effective time of the first identity verification transaction and prevent the occurrence of leakage or embezzlement.
Specifically, the user id of the first authentication assertion is the same as or different from the user id of the user node that sent the first authentication transaction. In other words, the creator who sends the first authentication transaction may be the user himself who owns the first authentication statement, or may not be the user himself, and only needs to obtain the user permission and receive the first authentication statement sent by the user himself.
Specifically, if the user id of the first authentication assertion is different from the user id of the user node that sent the first authentication transaction, the distributed authentication method includes: sending a request to establish a first authentication transaction; receiving a first authentication transaction; receiving information whether first identity authentication sent by a first authenticator node passes or not; wherein the request to establish the first authentication transaction comprises a first authentication assertion establishing a user identity identifier for the first authentication transaction. In other words, when the creator sending the first authentication transaction is not the user's own owner who owns the first authentication assertion, the first authentication assertion needs to be sent to the creator of the first authentication transaction in order to establish the first authentication transaction.
A distributed identity authentication method is suitable for a first authenticator, and comprises the following steps: receiving a first authentication transaction; requesting verification of a first authentication assertion from the blockchain system; and if the authentication is passed, sending the first authentication passing information to the user node. If the first identity authentication transaction is legal, only a transaction for verifying whether the first identity authentication statement is legal needs to be sent to the blockchain system, and if the first identity authentication statement is legal, the first identity of the user is verified by the first verifier. The first authenticator may trust the first identity information of the user. Specifically, the first authentication assertion is stored in a blockchain system.
