Abstract

An access control apparatus includes an acquisition unit and a changing unit.

The changing unit changes, on the basis of the access frequencies of the individual data groups, definition of data groups accessible by the individual access devices such as to reduce a difference in total access frequency of accessible data groups among the plurality of access devices.
