| Outline of Final Research Achievements |
In this study, we developed the prototype system to store important information of organizations. This system is operated in the organizations which have similar security policy and federated each other by some contract. This system divides the information into several shares which are redundant and distributable form by using Secret Sharing Scheme and stores these shares among the federated systems.
We proposed the management techniques not to compromise redundancy and dispersity, even if some organization wants to leave from the federation by the convenience. We also proposed and evaluated the secure outsourcing scheme of Secret Sharing Scheme for cloud storage services and confirmed the effectiveness of our proposal.
