Problems solved by technology

[0004] However, while cloud audit brings convenience to the audit business, it also faces challenges from internal and external security issues of audit data
First of all, at present, the audit data is firstly collected by the agencies stationed in the audit object, and then uploaded to the central cloud database for centralized management. Long time and high cost
In addition, when the audit data is uploaded to the cloud database and called by multiple organizations, its transmission is not highly encrypted, and it is easy to be cracked by hackers, resulting in data leakage and unauthorized abuse, copying, or even selling of audit data.

Embodiment Construction

[0032] The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

[0034] The terms "system" and "network" are often used interchangeably herein. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

Abstract

The application discloses a blockchain-based data storage method, electronic equipment and storage media. The data storage method includes that the first user node divides the sensitive data to be stored into the first type sensitive data and the second type sensitive data according to the data structure type; the first type sensitive data is encrypted and stored in the block chain; A corresponding digital fingerprint is generated for the second type of sensitive data, and the digital fingerprint is encrypted and stored in the block chain. Through the above method, data security is improved while avoiding affecting the processing capability of the blockchain network.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular to a data storage method, electronic equipment and storage medium based on block chain. Background technique [0002] Blockchain technology is a collection of new application technologies of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. From a data point of view, the blockchain is a chained data structure that combines data blocks in a sequentially connected manner in chronological order, and the data structure is cryptographically guaranteed to be tamper-proof and unforgeable. From a technical point of view, blockchain technology integrates a variety of different technologies. By building a blockchain network, each node in the network is allowed to obtain a complete copy of the data block, and based on the consensus mechanism and competitive computing To maintain the update of blockch...
