Title:
BLOCKCHAIN-BASED FILE MANAGEMENT/SEARCH SYSTEM AND FILE MANAGEMENT/SEARCH METHOD
Document Type and Number:
WIPO Patent Application WO/2018/043865
Kind Code:
A2
Abstract:
The present invention relates to a block chain-based file management and search system, wherein it is possible to check data name and owner. In the file management and search system, when generated data is stored and a data name is delivered in the form of a transaction to another node together with the IP address and port number information of a node in which the data is stored, nodes receiving the same generate blocks on the basis of said transaction and connect the blocks to a blockchain so that the data name and information about an owner who generated the data is shared by everybody. Since this information is recorded on the blockchain, all of the nodes share the same information. Therefore, in order for a malicious node to arbitrarily modify content, it is necessary for the malicious node to modify the blockchain content owned by all of the nodes. Accordingly, arbitrary modification is practically impossible, and thus the blockchain is inherently highly secure.
