P2P-type distributed online storage

Highly confidential online storage using blockchain and secret sharing method

Overview

　This invention realizes a P2P-type cloud storage mechanism based on the secret sharing method.

Impossible to identify the saving destination
Data is splited and stored in participating nodes. In addition, node-to-node communication is anonymous, making it secure and difficult to identify the storage location.

The client doesn’t need to retain metadata
Reduce the risk of metadata leak by decentralizing its storage in addition to the secret data itself by using the blockchain.

Possible to retrieve data securely
Secret data can be retrieved using user name and password. It can detect and eliminate brute force attack on username and password by mutual monitoring and majority voting among P2P nodes.
