Outline of Final Research Achievements

To prevent the loss of important electronic data even after a large-scale disaster which may annihilate the whole information processing systems of an organization, it is vital to store the backup data in a remote location. However, it is not easy for individual organizations to reserve such off-site backup sites on their own. Thus it is effective to develop a framework in which multiple organizations distributed in a wide area can keep their backup data mutually without disclosing their secret to other organizations.
For this off-site backup sharing system, this grant project worked on the development of on-demand reconstruction and back-ground reconstruction features which can restart its services safely and quickly before the whole lost data is restored.
