Communication device, communication system and method for managing access authority data
First Claim
1. A communication system which accepts an access from a single or plural other communication devices through a network in accordance with the operation of plural users, comprising:
- storage means;
an open segment comprising a first controller for access via a public network;
a non-open segment comprising a second controller for access via a dedicated line, the second controller being separate from, and not directly connected to, the first controller;
a common router for managing access to the open segment and access to the non-open segment, the common router coupled to at least one of the single or plural other communication devices by a dedicated line and the common router coupled to at least another one of the single or plural other communication devices by a public network, and the common router routing the access received from the public network to the open segment, and routing the access received through the dedicated line to one of the open segment and the non-open segment;
managing means for managing access authority data that defines access authority for at least one of first and second areas logically or physically defined in a storage area of said storage means and file data stored in the first and second storage areas related to at least one of a user who makes the access or a group to which the user belongs;
a first computing device, which is located in the open segment, for inquiring to said managing means in accordance with the access to the first storage area and controlling the access to the first storage area on the basis of the access authority data received from said managing means in response to the inquiry concerning every user or group; and
a second computing device, which is located in the non-open segment, for inquiring to said managing means in accordance with the access to the second storage area and controlling the access to the second storage area on the basis of the access authority data received from said managing means in response to the inquiry concerning every user or group.

Abstract
A communication device including an access authority data managing DB device for managing access authority data with which access authority for at least one of storage area defined logically or physically in a storage device. File data stored in the storage area is defined while at least one of a user making the access and a group to which the user concerned belongs is set as a unit. A non-open WWW device controls access to the storage device on the basis of the access authority data achieved from the access authority data managing DB device in accordance with an access from a terminal device.
