Access right information () indicating an access right of a user for a target file () is stored in a storage device () accessible from a server apparatus (). A management apparatus () acquires the access right information () from the server apparatus () and puts it in a storage device (). The management apparatus () acquires a request for key information that is used to decrypt a target file () from a user apparatus () operated by a target user (). The management apparatus () determines, upon the acquisition of the request, whether or not the target user () has an access right for the target file () by using the access right information () stored in the storage device (). The management apparatus () outputs the key information to the user apparatus () when it is determined that the target user () has the access right for the target file ().
