Distributed file storage sharing system based on alliance chain

Abstract

The invention belongs to the field of computer science, and discloses a distributed file storage sharing system based on an alliance chain. Through the alliance chain data interface module, the alliance file storage module, the alliance identity authentication module, the alliance authority control module and the node Web service module, distributed storage, file retrieval and file authorization of alliance files with identity access are realized, and safe sharing of files among alliance organizations is ensured. The invention provides an inter-alliance file distributed storage sharing solution with an identity authentication mechanism in order to overcome the defects of an existing block chain file sharing technology system, and provides development practice for inter-alliance data sharing, data barrier getting through and data island solving.

Description

technical field [0001] The invention relates to a distributed file storage and sharing system based on alliance chain, which belongs to the field of computer science. Background technique [0002] Since the publication of the Bitcoin white paper in 2008, the blockchain has gradually become a way for decentralized and trustless peer-to-peer organizations to securely store and transmit trusted data. Before the emergence of distributed ledger technology, data sharing was generally realized through data systems. Large-scale organizations, especially government departments and large financial institutions, will build organizational-level data warehouses or big data systems to achieve centralized collection, processing, storage, and application of internal data within the organization. However, if it is between multiple organizations, especially among peer-to-peer organizations, there are very few cases of data sharing through the construction of a unified data centralized system...

AI Technical Summary

Problems solved by technology

On the one hand, public chain systems without access control are difficult to supervise, so these systems have basically not caused any waves in the domestic market

On the other hand, in today's era of big data, the value of data is often much greater than the value of the physical equipment that stores the data. The operating model of these systems that only consider selling storage space is completely missing the point

[0005] However, there are few distributed storage system products based on the alliance chain. The main reason is that the storage system wants to implement a compatible identity authentication mechanism with the blockchain, so some existing distributed storage systems cannot be used directly.
