Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0035] refer to figure 1 As shown, the embodiment of the present invention provides a blockchain-based data retrieval method, specifically including:

[0036] Step S1. Obtain the credential information file signed by the enterprise and the user; the agreement signed by the user and the enterprise can be used as the corresponding credential.

[0037] Step S2, generating corresponding hash data through a hash function on the credential information file.

Abstract

The invention relates to a data retrieval method and system based on a block chain. The method comprises the following steps: acquiring a certificate information file signed by an enterprise and a user; generating corresponding hash data from the voucher information file through a hash function; requesting a block chain engine to obtain a user secret key; signing the Hash data by using the user secret key, generating new Hash data, and uploading the new Hash data to a corresponding node of a block chain; and synchronizing the new hash data to data persistence layers of other nodes of the block chain, so that the corresponding node performs high-speed query through a service gateway service. According to the scheme of the invention, the block chain technology is introduced, and the user credential record is provided for an enterprise to the block chain; the user certificate is ensured to be safe, real and effective by utilizing the characteristics of distribution, tampering resistance and the like of the block chain; the evidence storage uplink certificate is signed through a user key, the evidence storage uplink contract is encrypted and stored on the block chain, uniqueness and high credibility are achieved, and the authenticity and validity of data are easy to judge.

Description

technical field [0001] The invention belongs to the technical field of linking communication voucher files, and in particular relates to a blockchain-based data retrieval method and system. Background technique [0002] In the traditional processing method of user deposit and on-chain certificate files (signing agreements), the enterprise stores all user signing information in the enterprise's own database. With the development of the Internet era, the cloud deployment of enterprise applications, and the cluster deployment mode that supports high concurrency, enterprises will migrate applications to cloud hosts, store data in cluster databases, and may store multiple copies, and even consider To disaster recovery, the data is stored in a remote computer room. This method apparently solves the security and stability of data. But in essence, the data is still stored on the server under the control of the enterprise itself. If tampering occurs, users and third-party organizat...
