Problems solved by technology

[0002] With the development of technology, people began to explore the ability of blockchain + PKI technology to realize identity management and identity verification. However, the current technology has the following defects: 1) It is impossible to dynamically and flexibly bind ID cards and various electronic certificates, identity information It cannot be decoupled from the license information, and cannot be dynamically increased or decreased. 2) All residents’ identity privacy information or biometrics are stored in plain text, which poses a huge privacy leakage security risk
3) Certain permissions and identity restrictions are required when accessing the blockchain system, which runs counter to the openness, transparency and traceability of blockchain technology, and does not have true openness and compatibility
4) It is impossible to dynamically expand the type of certificate and the additional content of identity information. If new features and data fields are added, the software system of all nodes needs to be upgraded on a large scale, which is costly and extremely poor in stability
5) Cannot tolerate the leakage of the secret key of a single blockchain node, network attacks and system errors of node crashes

Embodiment 1

[0141] Contract signing backup: When both parties sign a contract, they can manage the contract through the above-mentioned blockchain-based user ID card management system, and store the contract in the form of hash value. Correspondingly, the ID numbers and signatures of both parties are also encrypted It is stored in the form of a hash value for later real-name verification and acquisition.

[0142] This method of use is intended to replace the current expensive and difficult-to-use CA certificate. The CA certificate is used to prove the real-name identity of both signatories when signing an electronic contract. The CA certificate is provided by the CA center, which has certain security risks and must be connected to the Internet for CA verify.

[0143] Through the block chain-based user ID card management of this scheme, the real-name information and electronic identity of the residents can be confirmed. The residents unlock the wallet secret key by unlocking the certificat...

Embodiment 2

[0146] Cross-network joint query: In the current government services, it is extremely cumbersome to issue certificates across departments or across provinces and cities. At the same time, it is almost impossible to realize business needs across provinces, cities and departments. Mutual mutual influence and credible communication, through the unique blockchain identity ID for system query and identity verification, through the docking of ID number HASH value and traditional identity information, cross-provincial and cross-departmental identity and certificate information sharing can be realized , and even modify the license information and status across provinces and departments.

Embodiment 3

[0148]Combined use with biometrics: through the joint use of biometrics and ID numbers, the identity of users is verified through biometrics and ID numbers. This solution can replace the use of physical ID cards. In the existing technical solutions, it is necessary to identify biometric features such as faces and combine physical ID cards for identity verification. However, physical ID cards often have problems such as loss, forgery, and damage. With the popularization of mobile phones, it has become a common phenomenon for everyone to hold a mobile phone. Through the blockchain license wallet APP, the same purpose as a physical ID card can be achieved, and it is more secure and easy to use than the traditional way of use.

[0149] Through above-mentioned technical scheme of the present invention, realized following technical effect:

[0150] 1) Through the network layering technology, the traditional blockchain storage and management of identity information is upgraded to a ...

Abstract

The present invention relates to a blockchain-based user ID card system and method. The system includes: a multi-layer blockchain network, including a main network and multiple parallel subnets, the number of the main network is one, and the number of subnets is The maximum number is 1023, and the main network and each subnet communicate through network slots. Both the main network and the subnet include a main blockchain node and multiple other blockchain nodes; the blockchain nodes of the main network Including the servers of public security organs in various regions, which are used to manage the endorsement of the legitimacy of the user's ID card, store the binding relationship between the user's blockchain identity ID and the unique legal identifier of the user's identity in each subnet, and each blockchain node of the subnet The account status of the user's identity, the hash value of the unique legal identification of the user's identity is bound to the user's blockchain identity ID; the blockchain nodes of the subnet include different parts of different certificate systems or servers in different regions related to the user's identity information, and the subnet The network is used to manage the digital ID card information of different license systems.
