PROBLEM TO BE SOLVED: To prove existence of electronic data at a specific moment of time, with high robustness.;SOLUTION: Electronic data becoming the registration object of existence proof is received. Next, a transaction embedding a bite arrangement BA, determined univocally based on the content of this electronic data, in a script is generated. Next, the transaction thus generated is digitally signed by public key cryptography, and broadcast to a virtual currency network 20 for taking into a block chain 21 of virtual currency. A transaction identifier TrID unique to the transaction is then associated with the bite arrangement BA and registered in a management database 5.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
