METHOD FOR MANAGING BLOCKCHAIN-BASED DOCUMENT USING MERKLE TREE STRUCTURE IN UTXO-BASED PROTOCOL AND SERVER FOR MANAGING DOCUMENT USING SAME

摘要

The present invention relates to a method for managing a document based on a blockchain by using a merkle tree structure in an unspent transaction output (UTXO)-based protocol and a server using the same, which store information on identity authentication and electronic document issuing in the blockchain, thereby minimizing a risk of arbitrarily writing an unauthenticated document. More specifically, the present invention relates to a method for creating the document for document management, that is, the method for issuing, a method for using the created document, that is, the method for reading, and a method for handling the created document, especially, the method for destroying.;COPYRIGHT KIPO 2018
