Abstract

A personal blockchain generation unit 51 of a service providing server group 1 generates or updates a unit file containing a history of transaction of data change related to a predetermined unit such as an account and a data for a plurality of users in an account management service of virtual currencies or medical information management service. A finality transaction file generating unit 52 generates a file containing a content of the transaction when the transaction in which the predetermined user is involved for each of the transaction related to the predetermined unit is finished. A management control unit 53 performs a control for storing the unit file independently from the other units and managing the unit file separately from the other units file for each of the units in a predetermined service. At this time, the unit file is managed as a block of a blockchain.

Claims4

Dependent claims

An information processing system comprising:

a unit file generation unit configured to generate or update a personal blockchain containing a history of transactions of only a predetermined user in a plurality of users in a predetermined service as a block independently from the personal blockchain of the other users;
a finality transaction file generation unit configured to generate a finality transaction file containing a content of one of the transactions in which the predetermined user is involved for each of the transactions;
and
a management control unit configured to perform a control for storing and managing the personal blockchain of the predetermined user independently from the personal blockchain of the other users for each of the plurality of users in the predetermined service and managing the finality transaction file for each of the transactions separately from the personal blockchain, wherein
the unit file generation unit is configured to generate a new personal blockchain of the predetermined user when the history of the transactions included in the personal blockchain of the predetermined user exceeds N and a (N+1)-th transaction is performed, the N being an integer of 1 or more,
the management control unit is configured to perform a control for managing the new personal blockchain of the predetermined user while associating with the personal blockchain of the predetermined user, and
the unit file generation unit is configured to generate the personal blockchain of a predetermined unit, the personal blockchain further containing a predetermined encryption matter in which a predetermined matter related to the predetermined unit is encrypted.
