Abstract
Disclosed is a method of providing bio-information data based on a plurality of blockchains. The method includes enabling a user blockchain node to store user block data including user information, a shared key, and a hash key for each user of a plurality of users, enabling an electronic contract blockchain node to store contract block data including contract information for a first user requesting a second user to generate bio-information data, the first user and the second user being included in the plurality of users, enabling a data transfer blockchain node to store transfer block data including storage information for at least one storage server that stores the bio-information data, and delivering the transfer block data from the data transfer blockchain node to the first user.
Core Innovation
The disclosure provides a method of providing bio-information data based on a plurality of blockchains. A user blockchain node stores user block data including user information, a shared key, and a hash key for each user of a plurality of users. An electronic contract blockchain node stores contract block data including contract information for a first user requesting a second user to generate bio-information data, with the first user and the second user included in the plurality of users.
A data transfer blockchain node stores transfer block data including storage information for at least one storage server that stores the bio-information data. The method authenticates the first user based on the user blockchain node, and when the first user is authenticated, delivers the transfer block data from the data transfer blockchain node to a first user terminal of the first user.
In system aspects, a user blockchain node, an electronic contract blockchain node, and a data transfer blockchain node operate together with a storage server to transfer bio-information data. The user block data, the contract block data, and the transfer block data are generated by at least one of the first user or the second user, and the transfer block data includes storage information for the storage server.
Claims Coverage
The independent claims cover a method of providing bio-information data using multiple blockchains with user authentication and delivery of transfer block data, a method of storing bio-information data with roles for user blockchain nodes, storage servers, and a data transfer blockchain node, and a system for transferring bio-information data using multiple blockchain nodes and delivering transfer block data after authentication. Across the independent claims, the inventive coverage centers on coordinating user block data, electronic contract block data, and data transfer block data with per-user hash keys and storage information for at least one storage server.
User blockchain storing user block data with shared key and hash keys
Storing, by a user blockchain node, user block data received from a plurality of user terminals of a plurality of users and including user information, a shared key, and a hash key for each user of the plurality of users.
Electronic contract blockchain storing contract block data for a request to generate bio-information data
Storing, by an electronic contract blockchain node, contract block data received from a second user terminal of a second user and including contract information for a first user requesting the second user to generate bio-information data, the first user and the second user being included in the plurality of users.
Data transfer blockchain storing transfer block data including storage information
Storing, by a data transfer blockchain node, transfer block data received from the second user terminal of the second user and including storage information for at least one storage server that stores the bio-information data.
Authentication based on the user blockchain node and delivery of transfer block data
Authenticating the first user based on the user blockchain node; and delivering, when the first user is authenticated, the transfer block data from the data transfer blockchain node to a first user terminal of the first user.
Storing bio-information data at a storage server as requested by the first user
Storing, by a storage server, bio-information data that is requested by a first user and generated by and received from a second user terminal of a second user, the first user and the second user being included in the plurality of users.
System with user blockchain, electronic contract blockchain, storage server, and data transfer blockchain delivering after authentication
A user blockchain node configured to store user block data; an electronic contract blockchain node configured to store contract block data; a storage server configured to store the bio-information data generated by and received from the second user; and a data transfer blockchain node configured to store transfer block data including storage information for the storage server, wherein the first user is authenticated based on the user blockchain node, and wherein, when the first user is authenticated, the transfer block data is delivered from the data transfer blockchain node to the first user.
Across the independent claims, the inventive subject matter is directed to coordinating multiple blockchains, user, electronic contract, and data transfer, with authentication based on user blockchain data and with delivery of transfer block data containing storage information for storing and accessing bio-information data.
