PROBLEM TO BE SOLVED: To allow use of a storage area of a second information processor with security secured when storage capacity of a first information processor used by a user is insufficient. SOLUTION: The first information processor has: an authentication information database storing authentication information for using the second information processor; a user database; and a use situation database storing a use amount of a storage area of the user database. The first information processor receives a data storage request from a third information processor, and acquires the use amount of the user database from the use situation database. When the use amount exceeds a prescribed value, the first information processor acquires the authentication information about the second information processor from the authentication information database, transmits an authentication request to the second information processor, and transmits a data substitution storage request including data set in the data storage request, a storage position identifier showing a storage position of the data, and an identifier of the first information processor to the second information processor.
