Abstract

A command authorization method that prevents a command issued by a third party from impersonating a command issued by a legitimate user, thereby maintaining high security. An authorization code stored in a command transmitted from a host is collated in a command authorization code parser. If the authorization code coincides with collating information therein, a command parser generates a predetermined access command, which is executed by a command controller.
