Embodiment Construction

[0019] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0020] This disclosure is applied to the blockchain network. The blockchain is an open, transparent and non-tamperable data storage structure. It stores each data that needs to be stored as an independent data structure in the form of blocks. , each data block contains: timestamp, block number of the previous block, hash value of the previous block, data content of the current block, etc. Through the proof-of-work mechanism, the blockchain guarantees that only one person can generate and broadcast the same block, and other people can only synchronize the copy without making any changes to it. Based on the above characteristics, the storage of certification d...

Abstract

The invention relates to a certificate storage system and a block chain network, the certificate storage system is applied to the block chain network, and the block chain network comprises a certificate storage node, a query node and a verification node; the evidence storage node is used for encrypting a certificate file and storing the encrypted certificate file and a file fingerprint of the certificate file into the block chain network; the query node responds to the query request submitted to the query node, verifies the identity legality of the user based on the information of the user logging in the query interface, and returns the certificate file to the query interface after the identity legality verification is passed; and the verification node responds to the verification request submitted to the verification node, checks the validity of a to-be-verified certificate file based on the file fingerprint of the to-be-verified certificate file and the file fingerprint stored in the block chain network, and returns a file verification result to a verification interface.

Description

technical field [0001] The present disclosure relates to the field of data storage, and in particular, to a certificate storage system and a blockchain network. Background technique [0002] In the scenario of handling evidence-related business, due to the high timeliness and high authenticity requirements caused by the special use of evidence, there are cumbersome procedures in the access of evidence to prove the authenticity and timeliness of evidence. In some cases, users need to go through different procedures in different places to make the evidence legally effective, which undoubtedly reduces the efficiency of users when handling evidence deposit and collection services. With the popularization of Internet technology, how to reduce the difficulty of accessing evidence through Internet technology and improve the efficiency of users' business transactions has become an urgent problem to be solved. Contents of the invention [0003] The purpose of this disclosure is to...
