METHOD AND APPARATUS FOR ACCESS CONTROL

摘要

An access control apparatus includes an acquisition unit and a changing unit. The acquisition unit divides the data stored in a storage device, which is to be accessed from a plurality of access devices, into a plurality of data groups, and obtains the access frequencies of the individual data groups, which are based on accesses to the data belonging to the data groups. 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.

主权项

1. A non-transitory computer-readable storage medium storing a computer program that causes a computer to perform a process comprising:
obtaining an access frequency of each of a plurality of data groups, which is based on accesses to data belonging to the plurality of data groups, the plurality of data groups being generated by dividing data that is stored in a storage device and is accessed from a plurality of access devices; and changing, based on access frequencies of the plurality of data groups, definition of data groups accessible by individual ones of the plurality of access devices such as to reduce a difference in total access frequency of accessible data groups among the plurality of access devices.
