Embodiment 1

[0030] figure 1 It shows a flow chart of an identity verification method based on the combination of block chain and iris recognition in the present invention, which specifically includes the following steps:

[0031] Step S1: Identity verification request, the user submits the identity verification request, establishes the iris recognition blockchain, and obtains the user's iris feature data;

[0032] Step S2: Identity verification, judging whether there is matching feature data in the user data storage blockchain; if the feature data does not exist in the data storage blockchain, the user identity will be reviewed; if the user passes the review, the The feature data is written into the data storage blockchain and synchronized to each node of the identity verification blockchain node, and the user is assigned user activity permissions; if the user fails the review, return to step S1 and prompt the user to re-identify Verify; if the feature data exists in the data storage blo...

Embodiment 2

[0040] figure 2 It shows a block diagram of an identity verification device based on the combination of blockchain and iris recognition of the present invention, which specifically includes the following modules:

[0041] Identity verification request module 101, the user submits identity verification request, sets up iris recognition block chain, obtains user's iris feature data;

[0042] The identity verification module 102 judges whether there is matching feature data in the user data storage block chain; if the feature data does not exist in the data storage block chain, the user identity is checked; if the user passes the review, the The feature data is written into the data storage block chain, synchronized to each node of the identity verification block chain node, and assigns user activity permissions to the user; if the user fails to pass the review, then return to the identity verification request module (101), prompting The user re-authenticates; if the feature da...

Abstract

The invention provides an identity verification method and device based on the combination of a blockchain and iris recognition. A user submits an identity verification request, establishes an iris recognition blockchain, obtains user iris characteristic data and judges whether characteristic data matched with a user data storage blockchain is in the presence in the user data storage blockchain ornot; if the characteristic data is not in the presence in the data storage blockchain, user identity is checked; if the user passes the checking, the characteristic data is written into the data storage blockchain, meanwhile, the characteristic data is synchronized to each node of an identity verification blockchain node, and user activity permission is distributed to the user; if the user does not pass the checking, the user is prompted to carry out identity verification again; and if the characteristic data is in the presence in the data storage blockchain, the user is prompted to directlycarry out the user activity. A credit evaluation blockchain node monitors the credit behaviors of the user activity in real time, if a monitoring result shows that the user has a violation behavior inthe user activity, the user activity of the user is restricted, meanwhile, data information before the user activity is only kept, and behaviors of breaching promises and the data information beforean operation are informed to other nodes in the blockchain.

Description

technical field [0001] The invention relates to the field of identity verification, in particular to an identity verification method and device based on the combination of blockchain and iris recognition. Background technique [0002] Traditional authentication includes authentication based on shared key, authentication based on biological characteristics and authentication based on public key encryption algorithm. Different authentication methods have different levels of security. The storage of authentication information still depends on the data center, and the processing capacity of the data center will affect the efficiency of authentication. In addition, there is still a risk of user information being stolen in the data center. For example, in the patent document with the application number 2017111051299, a smart campus quick access control method based on multiple identity features is disclosed, which includes the following steps: Step 1, establish a cloud campus dat...
