File reading and storing method based on blockchain technology, terminal equipment and storage medium

Abstract

The invention relates to a file reading and storing method based on a block chain technology, terminal equipment and a storage medium. The file reading method comprises the steps that a client relatedto a first user sends a file reading request message for a to-be-read file to a storage node network, and the to-be-read file is stored in the storage node network in an off-chain distributed mode inthe form of multiple file fragments; the storage node network performs consensus verification on whether the signature of the first user is matched with a public key of the first user in the storagenode network; under the condition that the verification is passed, the storage node network sends a plurality of file fragments of the to-be-read file to a client related to the first user; and restoring the to-be-read file from the plurality of received file fragments by the client related to the first user. Therefore, a scheme for sharing the data file, which is high in safety among the nodes inthe storage node network and high in data capacity expandability, is provided.

Description

technical field [0001] The present disclosure generally relates to the technical field of data file access, including the writing and reading of data files, and specifically relates to a method for reading and storing files based on blockchain technology, terminal equipment and computer-readable Read storage media. Background technique [0002] In today's information society, no matter whether it is an organization or an individual, any operation on the computer network will generate data, and these data include many important and sensitive privacy data. Privacy data, for example, personal ID information, bank card number, social security card number, patient medical data (such as medical imaging data such as CT photos), personal user names and passwords on different websites, and the like. These data or information are usually stored in the form of files on disks in computer networks or other external storage media. For the storage and management of private data, how to e...

Problems solved by technology

However, the application of these blockchain technologies in privacy data management faces two problems: (1) Due to the irreversibility of information transmission, it is difficult to control and limit the scope of use of private data after it is directly shared on the chain; and (2) ) The storage capacity of the blockchain is not enough to support private data with a huge amount of data, and the on-chain of private data will cause unbearable congestion to the blockchain
