Abstract: According to one aspect of the present invention, there is provided a method for managing a medical information platform using a blockchain, the method comprising the steps of: dynamically calculating an exchange ratio between tokens and points, with reference to at least one of an amount of points that a user intends to exchange for tokens on a medical information platform, an amount of tokens that the user intends to exchange for points on the medical information platform, an amount of tokens present in a token pool managed by the medical information platform, and an amount of points previously exchanged for tokens on the medical information platform; and providing the user with the tokens or points exchanged with reference to the calculated exchange ratio.

Abstract: According to one aspect of the present invention, there is provided a method for supporting non-face-to-face authentication in a blockchain network, the method comprising the steps of: providing an authenticatee node with authentication result information generated as face-to-face authentication for personal information of an authenticatee is performed by at least one authenticator node in a blockchain network, and matching and recording non-invertible operation information on at least a part of the authentication result information to an account associated with the authenticatee in the blockchain network; and when a request for non-face-to-face authentication of the authenticatee is made by an authentication requester node, verifying validity of information for authentication, which is provided from the authentication requester node for the request for the non-face-to-face authentication of the authenticatee, on the basis of the non-invertible operation information recorded in the blockchain network.

Abstract: According to one aspect of the present invention, there is provided a method for providing a blockchain-based medical information platform, the method comprising the steps of: managing data input/output between a core layer consisting of a distributed database for storing encrypted medical information and an application layer for providing an application program utilizing the medical information, with reference to information stored on a blockchain; and providing a smart contract for managing at least one of information on tokens or points, information on user accounts, and information on a location where the medical information is stored, with reference to the information stored on the blockchain.
