Abstract: Provided is a file management/search system based on a block chain capable of identifying a data name and an owner of a data. In the file management/search system, a generated data is stored, and a data name together with an IP address and port number of a node in which the data is stored is transmitted in a form of a transaction to other nodes. The nodes receiving the transaction generates blocks on the basis of the transaction and links the blocks to the block chain, so that the data name and the owner information of the owner generating the data are shared by all users. Since this information is recorded in the block chain and all the nodes share the same information, a malicious node which is to arbitrarily change contents needs to change the contents of the block chain held by all the nodes.
