A cross-regional sharing method of electronic certificate data

Abstract

The invention discloses a method for cross-regional sharing of electronic license data. First of all, through the electronic license business contract relationship, the first electronic license file and the first electronic license information can be written into the account books corresponding to all subset blockchains of the first block storage node subset, and then the first routing The information and the first electronic license information are written into the ledgers corresponding to all the complete block chains of the cross-block storage node complete set. In the embodiment of the present invention, based on the accounting of the subset blockchain in the region and the accounting of the complete blockchain in the cross-region, the double-layer bookkeeping of electronic certificates in the subset blockchain and the complete blockchain is realized. , does not need to adopt a centralized data storage method, and realizes data decentralization and cross-regional sharing of electronic certificate data for synchronous accounting applications, meets the data synchronization requirements between electronic certificate databases in different regions, and reduces the possibility of data tampering , Realize cross-regional data sharing of electronic certificates.

Description

technical field [0001] The invention relates to the technical field of electronic certificates, in particular to a method for cross-regional sharing of electronic certificate data. Background technique [0002] With the development of electronic license informatization, electronic license platforms have been established in many regions, and a large amount of electronic license data has been accumulated. For example, electronic license platforms have been established in many cities and provinces. However, the data standards of electronic certificates in these cities and provinces may be different, and the system design structure may also be different. There is no way to achieve cross-regional electronic certificate information sharing. In fact, the electronic certificate platforms in each region are still "information islands" one by one. ". [0003] Cross-regional sharing can solve the problem of sharing and trusting electronic certificates between different regions, and is...

Problems solved by technology

For example, the data sharing method in the prior art is to collect data into a unified data resource center. When the network of the data resource center is abnormal or the data provider forgets to update the data status, it is easy to cause data liability issues. Suppose it is a license information. In fact, it has been invalidated, but the data provider did not update the data to the data resource center, or submitted it to the data resource center but an exception occurred, which caused the data resource center to not perform the update, and the data user obtained the data from the data resource center At this time, the data at this time cannot be trusted

[0004] Therefore, the centralized electronic certificate sharing scheme adopted in the existing technology is prone to the problem of irrelevant rights and responsibilities in the process of information collection and application, which leads to the problem of untrustworthy data in data sharing.
