Abstract

PURPOSE: To secure secrecy by limiting access by providing a registering means for users and passwords, inputting the owner's name and password of a file when storing a document, and managing the file and its use permission information. CONSTITUTION: Concerning a facsimile 102 connected to a LAN 101, the file to be stored in a hard disk 104 is managed by a file managing part 102A and the user's name and the password are registered in a user registration table. When storing the document, the managing part 102A manages the file use permission information together with the file by inputting the owner's name and password of the file. When transmitting the file, a receiving user's name is inputted, the receiving person of the file is designated and the storage of the received file is also managed similarly to the storage of the document. The output of the file can be provided by inputting correct user's name and password. Thus, the access of unspecified user connected with the LAN can be limited so that secrecy can be kept.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a LAN facsimile.

[0002]

2. Description of the Related Art Conventionally, in a system in which a facsimile, a copying machine, a personal computer, and a printer communicate with each other via a LAN (local area network), files handled by the facsimile have file attributes such as permission and prohibition of use. No means was specifically provided for specifying.

[0003]

Therefore, a user who is working at a terminal connected to the LAN can easily access the document on the facsimile and the confidentiality is not maintained.

An object of the present invention is to provide a LAN facsimile which can secure the confidentiality of files on a facsimile for an unspecified user who uses a terminal on the LAN.

[0005]

According to the present invention, a facsimile connected to a LAN has a means for performing user registration and a means for performing password registration. When storing documents, the file owner name and The feature is that the password is entered and the file use permission information is managed together with the file.

[0006]

1 is a block diagram showing the configuration of a LAN system according to an embodiment of the present invention.

As shown in the figure, in the LAN 101 of this embodiment, a facsimile 102, a copy 105, and a personal computer 10 which perform image communication via a public line 103.
6, 108 and the printer 107 are connected.
A hard disk 104 that stores files is connected to the facsimile 102, and the hard disk 1
A file management unit 102A for managing the 04 file is provided.

The processing in the transmitting side and receiving side facsimiles connected to the LAN system will be described below.

First, the processing in the case where the user performs user registration in the transmitting side and receiving side facsimiles connected to the LAN will be described with reference to the flowchart of FIG.

When the user makes a user registration request to the facsimile, the facsimile displays the user registration screen as shown in FIG. 3 on the LCD screen of the operation panel (not shown), and in step S201, the user is informed by blinking display or the like. Prompt for first name. Then, when the user name is input, next, in S202, a password input is prompted.
As a result, the entered user name and password can be changed as shown in FIG.
Register in the user registration table shown in.

Next, a case where a user transmits a document by a facsimile connected to the LAN will be described with reference to the flowchart of FIG.

When a user sets a transmission document in a scanner (not shown) and executes a transmission operation,
The permission screen shown in FIG. 6 is displayed in S501, and the user name is registered in S502. If the user name is registered, the user is prompted to enter the password, and it is confirmed whether the input password and the user name are the passwords registered in FIG. 4, and if they are correct, S504 is entered.
Proceed to. If there is no user registration in S502, the process proceeds to S504.

In S504, it is determined whether or not the recipient name is input. If there is an input, in S505, the file use permission information of the file name, the user name, and the recipient name is stored in the file use permission information table shown in FIG. To register. After this, the process proceeds to S506.

If the recipient name is not input in S504, the process proceeds to S506. And S50
At 6, the transmitted document is stored.

Further, in S507, if the file name of the transmission file is in the file use permission information table of FIG. 7, it is judged whether the recipient name is registered, and if it is registered, as shown in FIG. NSC of session start command (CSS) which is a command of G4 protocol
The ASCII code of the recipient name is set in the recipient name portion (F82) of (non-standard terminal function). Then, in step S508, the transmission process is performed and the transmission ends.

Next, the processing in the facsimile on the receiving side connected to the LAN will be described with reference to the flowchart of FIG.

When the receiving facsimile starts receiving,
In S901, a session start command (CSS)
The NSC (non-standard terminal function) recipient name part (F82) is analyzed, and if the recipient name is set, in step S902, the reception facsimile is stored in the file use permission information table of the reception facsimile shown in FIG. The determined file name is set in the file name field, and the recipient name of the non-standard function is set in the user name. In step S903, the received document is accumulated, and the reception process ends.

Next, file processing in the transmitting side facsimile and the receiving side facsimile will be described with reference to the flowchart of FIG.

When the user accesses and outputs the document on the hard disk 104, it is confirmed in S111 whether the document to be output is registered in the file use permission information table.

Then, if the file is registered in S112, the process proceeds to S113, the user confirmation screen of FIG. 12 is displayed, and the user name and password are input.

If the file name and the user name are correct in S114, the user registration table of FIG. 4 is referred to, and it is confirmed whether the password of the user name is correct. If it is correct, the document is output in S115, and the output process ends.

If the file is not registered in S112, the output process is stopped and the process ends. If the permission for the file is not granted in S114, the output process is stopped and terminated.

In this way, by providing the function of registering the user name and password in the facsimile 102 connected to the LAN 101, the use of the file by an unspecified user can be restricted, the confidentiality can be secured, and the system economy can be improved. Can be improved.

[0024]

As described above, according to the present invention,
User registration and password registration can be performed in a facsimile connected to a LAN.
When storing documents in a fax machine connected to, the file owner name and password must be entered to manage the file use permission information together with the file. Also, in the case of a fax machine connected to a LAN, Specify the recipient of the file by inputting the receiving user name and putting the receiving user name on the NSC (non-standard function) of the G4 facsimile protocol.
When receiving by a facsimile connected to a LAN, if the recipient user name is specified in the NSC (non-standard function) sent from the sending facsimile, the file use permission information is managed together with the file when the received files are stored, Also, when the recipient outputs the file, if the file specifies a particular recipient, the password is input, and if the password is correct, the file is output,
There is an effect that access to an unspecified user who is working at a terminal connected to the AN can be restricted and confidentiality can be maintained.
