Outline of Final Research Achievements

Cloud storage supporting data-driven services requires an audit function to verify the integrity of data stored by users. Authentication and authorization functions are also relevant to the construction of an environment where various entities can trade data, such as in an IoT ecosystem where data providers, analysts, and users interact with each other. This research investigated a third-party auditing system that does not require any additional processing by the user, as well as a distributed authentication system and a cooperative authorization system.
