US 11,687,664 B2 · Blockchain-based file storage device and file access authorization system and method

Abstract

This invention relates generally to blockchain application implementations. It can be used for allowing regular users to obtain formal authorization for accessing files from blockchain powered file storage devices. Before a user accesses a file, a smart contract should be invoked and check if the user device possesses an authorized file access token which is non-fungible token and recorded in the blockchain network. Accordingly, this invention can turn a file abstractly into a token that can be traded or distributed on the internet. Furthermore, these files are encrypted by the access token and binding with it, unauthorized access or illegal copy is not possible. Eventually, Digital File becomes tradable and unique Digital Asset, which will result in a new era of e-commerce transactions. Virtual things Real.

Dependent claims

A file access authorization method based on a blockchain network having at least one user endpoint corresponding to a user device, and at least one content supply endpoint corresponding to a content server, the method comprising the steps of:

(A) obtaining from a machine-readable medium, by the user endpoint, a first public key and a first private key, and connecting the user endpoint to a smart contract stored in the blockchain network through the first public key, the smart contract comprising at least one file access token corresponding to the first public key;
and
(B) signing, by the user endpoint, the smart contract with the first private key for transferring the file access token corresponding to the first public key to the user endpoint;
wherein the smart contract, in response to a request made by the user device to access a file in the content server, provides a link for the user device to access the file after having authenticated the file access token of the user endpoint.

1 more element

A file storage device based on a blockchain network having at least one user endpoint corresponding to the storage device, and at least one content supply endpoint corresponding to a content server, wherein the storage device is connected with the blockchain network through an access device;

wherein, in response to a request made by the storage device or the access device to access a file in the content server, the access device obtains, from a machine-readable medium, a first private key and a first public key and is connected to a smart contract stored on the blockchain network through the first public key, wherein the smart contract comprises at least one file access token corresponding to the first public key;
the access device signs the smart contract with the first private key for transferring the file access token corresponding to the first public key to the user endpoint;
the smart contract, after having authenticated the file access token of the user endpoint, provides a link for the storage device to access the file in the content server.
