Embodiment 1

[0024] figure 2 It is a flow chart of a blockchain-based identity authentication method provided in Embodiment 1 of this application. Such as figure 2 As shown, the method includes:

[0025] Step S210: Obtain the authentication factor of the user terminal according to the identity authentication request sent by the user terminal.

[0026] In the embodiment of the present application, after receiving the identity authentication request sent by the user terminal, the authentication factor of the user terminal is obtained from the identity authentication request. Wherein, the authentication factors included in the request information may be single or multiple. The type of the authentication factor can be a user name type, a user password type, a device fingerprint type, a dynamic code type, a behavior habit type, or a combination of the above types. This embodiment of the present application does not specifically limit it, and those skilled in the art can flexibly set it ac...

Embodiment 2

[0035] image 3 It is a flow chart of a blockchain-based identity authentication method provided in Embodiment 2 of this application, and the execution subject of this embodiment is preferably an authentication server. Such as image 3 As shown, the method includes:

[0036] Step S310: Obtain the authentication factor of the user terminal according to the identity authentication request sent by the user terminal.

[0037]In the embodiment of the present application, after receiving the identity authentication request sent by the user terminal, the authentication factor of the user terminal is obtained from the identity authentication request. Wherein, the authentication factors included in the request information may be single or multiple. The type of the authentication factor can be a user name type, a user password type, a device fingerprint type, a dynamic code type, a behavior habit type, or a combination of the above types. This embodiment of the present application d...

Embodiment 3

[0049] Figure 4 It is a flow chart of a blockchain-based identity authentication method provided in Embodiment 3 of the present application, and the execution subject of this embodiment is preferably a user terminal. Such as Figure 4 As shown, the method includes:

[0050] Step S410: Send an identity authentication request including the authentication factor of the user terminal to the authentication server, so that the authentication server can create a smart contract based on the authentication factor, and the smart contract pre-stores the calculation result of the authentication factor.

[0051] Among them, the user terminal actively sends an identity authentication request containing authentication factors to the authentication server, and the authentication request includes a single or multiple authentication factors, including but not limited to user name, user password, device fingerprint, dynamic code, and behavior habits, etc. .

[0052] In other embodiments, the...

Abstract

The embodiment of the application discloses an identity authentication method based on a block chain, an authentication server and a user terminal, and belongs to the technical field of identity identification. The method comprises the steps of: according to an identity authentication request sent by the user terminal, acquiring an authentication factor of the user terminal; according to the authentication factor, creating a smart contract, wherein an operation result obtained after a preset operation is carried out on the authentication factor is pre-stored in the smart contract; broadcasting the smart contract into the block chain, and sending a smart contract block chain account address to the user terminal; and according to an execution result obtained after the user terminal executes the smart contract by utilizing the authentication factor, carrying out identity authentication, wherein when the execution result is matched with the operation result, success of identity authentication is confirmed, and when the execution result is not matched with the operation result, failure of identity authentication is confirmed. Therefore, the identity authentication method in the embodiment of the application has very high safety.

Description

technical field [0001] The embodiment of the present application relates to the technical field of identification, and in particular to a blockchain-based identity authentication method, authentication server, and user terminal. Background technique [0002] Identity authentication refers to the process of confirming the identity of the operator in the computer and computer network system, so as to determine whether the user has access and use rights to a certain resource, so that the access policy of the computer and network system can be implemented reliably and effectively , to prevent attackers from posing as legitimate users to gain access to resources, to ensure the security of systems and data, and to protect the legitimate interests of authorized visitors. [0003] Such as figure 1 As shown, in the traditional third-party identity authentication system, assuming that application server A needs to confirm the identity of user B, the main process is as follows: 1.1. U...
