WIPO Patent Application WO/2014/188743

A1

A hierarchy definition management unit (012) stores priority between hierarchy levels. An organization information management unit (013) stores information that indicates pairs of hierarchy elements for each hierarchy level combination. A role allocation management unit (011) stores information by which a condition that permits access is correlated with a specific hierarchy element. A process reception unit (005) inputs, from a user, an operation request requesting access to resources. An F-RBAC unit (006) identifies a hierarchy element corresponding to the user, extracts from the information of the organization information management unit (013) of a hierarchy element that is paired with and is one hierarchy above the identified hierarchy element, on the basis of priority between hierarchy levels, repeats the operation to extract a hierarchy element of a level that is paired with and is one level above the extracted hierarchy element, compares the identified hierarchy element and the extracted hierarchy elements to the hierarchy elements defined by the role allocation management unit (011), and determines whether to allow access.
