Abstract

The invention relates to a file storage and reading method based on the block chain technology, terminal equipment and a computer readable storage medium. The file storage method comprises the following steps: dividing a to-be-stored file into a plurality of file fragments by a client related to a first user, and sending a write-in operation message for the to-be-stored file to a storage node network; 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 storage node network; and under the condition that the verification is passed, enabling the plurality of file fragments to be distributed in the storage node network under the chain. Therefore, a scheme for sharing the data file, which is high in safety among the nodes in the 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 storage and access of data files, including writing and reading of data files, and specifically relates to a method for storing and reading files based on blockchain technology, and terminal equipment and computer readable 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 dat...
