First Claim
1. A communication device 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 unit;
an open segment comprising an open access controller for access via a public network;
a non-open segment comprising a non-open access controller for access via a dedicated line, the non-open access controller being separate from, and not directly connected to, the open access 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;
a managing unit for managing access authority data that defines access authority for at least one of a directory defined in a storage area of said storage unit and file data stored in the directory related to at least one of a user who makes the access or a group to which the user belongs; and
an access control unit for inquiring to said managing unit in accordance with the access and controlling the access to said storage unit on the basis of the access authority data received from said managing unit in response to the inquiry concerning every user or group,wherein the managing unit and said storage unit are commonly used by both the open access controller and the non-open access controller,wherein the common router carries out routing of access received from both the dedicated line and the public network.

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 and 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, and a non-open WWW device for controlling an 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.

10. A communication method for receiving access from single or plural other communication devices to a storage unit through a network in accordance with an operation of plural users to perform prescribed processing, comprising:
-
a step of managing access authority data in which access authority for at least one of a directory defined in a storage area of the storage unit and file data stored in a directory concerned is defined while at least one of a user making the access or a group to which the user belongs is set as a unit; a step of receiving access request from either a public network or a dedicated line through a router common to the public network and the dedicated line; a step of controlling access from the public network to an open access segment via an open access controller; a step of controlling access from the dedicated line to a non-open segment via a non-open access controller, the non-open access controller being separate from, and not directly connected to, the open access controller; and a step of controlling the access to the storage unit on the basis of the access authority data in accordance with the user or the group as a unit, wherein the access authority data and said storage unit are commonly used by both the open access controller and the non-open access controller, wherein the common router carries out routing of access received from both the dedicated line and the public network, 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. - View Dependent Claims (11, 12, 13, 14, 15)
