Data sharing method based on plurality of blockchains

Abstract

Provided is a data sharing method based on a plurality of blockchains. The method includes registering, by a management server, user block data which includes user information and a hash key of each user of a plurality of users in a user information blockchain, receiving, by the management server, storage information of data provided by a first user from a storage server, and receiving, by the management server, a request for specific data from a second user and transmitting storage information of the specific data to the second user.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit under 35 USC 119(a) of Korean Patent Application No. 10-2018-0035570 filed on Mar. 28, 2018, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.BACKGROUND1. Field[0002]The following description relates to a data sharing method based on a plurality of blockchains. The following description relates to a platform for data transaction relay and data sharing based on sharing economy, and more particularly, to a method of sharing data, which is owned by an individual, between subjects of a transaction, the method serving to integrate management as a transaction relay platform between a data provider and a data user.2. Description of Related Art[0003]As existing information and communication technology is combined with the recent paradigm shift from owning to sharing, digital information is increasing. For example, a sharing economy is...

Benefits of technology

[0006]When blockchain technology is applied to such a sharing economy, all participants may safely register, keep, and share idle resources together, solve security problems such as hacking and manipulation of idle resources, and also ensure the reliability of transaction records through verification.

[0007]Data may be composed of various kinds of information. For example, data may include specific genomic information, treatment information, and life information of various creatures including humans. Since the probability of a disease may be estimated from data of a human, it is possible to implement customized precision medicine for providing the most appropriate treatment to every patient. Among various kinds of data related to precision medicine, it may be very difficult to collect genomic information and treatment information of a specific group due to various loopholes of regulations and systems, high cost, time consumption, and the like. Also, life information is a record of unique lives, such as lifestyles and environments, which vary depending on individuals, and it may be difficult to collect life information unless individuals provide their information. Since personal data of individuals may be de-identified and then safely shared, these problems may be solved through a blockchain-based integrated data management platform on which a researcher and a research institution using personal data may obtain reliable data.

[0008]In other words, individuals are rewarded for providing and lending personal information and personal data, which is their idle resource, and data users obtain necessary data by paying use fees for necessary data such that a win-win economic system may be established. When researchers and institutions develop customized medicines and programs through various research results based on such idle resources, new medical science may be developed, and a burden to a society may be eased with a reduction in medical cost. Therefore, it is possible to create a high added value by enhancing public healthcare.

[0009]The following embodiments may accelerate data sharing and use by applying the blockchain technology to a sharing economy-based platform and may improve users' data accessibility and management efficiency by facilitating use of a public-domain software source. Also, the following embodiments may ensure security, reliability, and immediacy through a systematic security system capable of transparently and flexibly coping with the risk of hacking, an increase in the amount of data, and sharing when managing big data which is a large amount of integrated data. Further, the following embodiments may make it possible to construct an economic incentive system based on rewards and use fees such that participation of users may increase and a reduction in cost and time may be expected.

[0010]The following embodiments introduce the blockchain technology, thereby safely registering, keeping, and sharing data which is an idle resource shared among all participants, solving security problems of data hacking and manipulation, and providing a verification-based data transaction system and method.

[0013]The following embodiments provide an integrated management system and method for blockchain-based shared data in which a borrower may search shared data for necessary data and receive the necessary data from a storage.

Problems solved by technology

Among various kinds of data related to precision medicine, it may be very difficult to collect genomic information and treatment information of a specific group due to various loopholes of regulations and systems, high cost, time consumption, and the like.

Also, life information is a record of unique lives, such as lifestyles and environments, which vary depending on individuals, and it may be difficult to collect life information unless individuals provide their information.
