FIG. 6 is a diagram showing a display example in which the annotation edit history list screen 601 is displayed on the display device 112 of the user terminal 111 in FIG. In this example, the contents of the annotation information file 108 stored in the external storage device 107, that is, the contents described in FIG. As a result, it is possible to confirm in a list which user has made what change, when and for what annotation.

Hereinafter, referring to the flowchart of FIG.
The operation of the document processing system according to the present embodiment will be described.

First, a user starts a program of the document processing system from the terminal 111 (step S10), and inputs a user name and a password from the input device 114 of the user terminal 111 (step S20).

The data input in step S20 is transmitted to center device 101 via communication line 121.
In the center device 101, the entered user name and password are referred to the user name 201 and password 211 of the user information file 104 stored in the external storage device 103 to perform user authentication (step S30).
For example, when the user inputs “kuma” for the user name and “gai” for the password, the user name “kum” in FIG.
a "202 and the password" gai "212, the user authentication is successful. In this case, since the access right 221 is the “editing right” 222, “editing right” is assigned as the access right to the annotation. If the user authentication has failed, the authentication failure is displayed on the display device 112 of the user terminal 111 (step S140), and the program ends.

When the user performs an operation to instruct document processing using the input device 114, the document selected by the user is called from the center device 101 via the communication line 121 (step S50). For example, if the user selects the document with the document name “Report 1” 302, the center apparatus 101 refers to the document information file 106 stored in the external storage device 105, and the document name “Report 1” 302
Entity file "report1" 312 corresponding to
A portion corresponding to the document in the contents of the annotation information file 108 stored in the external storage device 107 is transmitted to the user terminal 111 via the communication line 121. Here, as described with reference to FIG. 4, “Annotation 1” and “Annotation 2” that are the annotation information of “Report 1” are transmitted. Note that a file accompanying the annotation (for example, “annotation graphic 1” accompanying “annotation 1” and “character 1” accompanying “annotation 2”) are also transmitted at the same time.

Here, an access right for performing document processing is determined. In this example, since the user having the editing authority is accessing, the editing of the annotation is permitted, and the process proceeds to step S100 (step S60).

The system device 113 includes a user terminal 111
File “report1” 31 sent to
2 and the annotations 502 and 503 of the entity file based on the information of the annotation 2 and the annotation, and the display device 112 of the user terminal 111 as described with reference to FIG.
(Step S100).

Here, when the user performs an editing operation of the annotation (step S110), an inquiry screen as to whether to save the edited contents is displayed on the display device 112 of the user terminal 111 (step S120). When the edited content is to be saved, the edited content, the signature, and the date and time are sent to the center device 101, and are saved in the annotation information file 108 by the center device 101 (step S13).
0). For example, on the screen displaying “Report 1” in FIG.
It is assumed that “annotation 2” indicated by 503 has not been input, and that the user has performed a predetermined operation of inputting a new annotation from that state and input the annotation character 531 to create the annotation 503. I do. Assuming that the user instructs to save the annotation, the annotation name “annotation 2” 403 and the user name “kuma” 20
3. Save date and time "2000/03/03 06: 30: 3
The “0” 413, the editing content “add character 1” 423 and the document name “report 1” 303 are recorded in the document information file 106 of the external storage device 105.

If the annotation editing operation is not performed in step S110 and the edited content is not stored in step S120, the process returns to step S40. Step S6
If the access right of the annotation is determined to be 0 and the user does not have the editing right, the process proceeds to step S70.

In step S70, it is determined whether the user has the authority to refer to the annotation. If the user does not have reference authority, the contents of the entity file of the document called in step S50 are displayed on the display device 112 of the user terminal 111 (step S80), and the process returns to step S40. If the user has the reference authority for the annotation in step S70,
The same processing as in step S100 is performed (step S9
0), and return to step S40.

When the user performs an operation to end the program using the input device 114 (step S40), the program is ended.

When the user performs an annotation editing history list display operation, the annotation information file 108 stored in the external storage device 107 is transmitted to the user terminal 111 via the communication line 121 (step S150), and the editing is performed. A history list display screen (for example, FIG. 6) is displayed on the display device 112 of the user terminal 111 (step S160).

The above-described embodiment is a network type system including the center device 101, the communication line 121, and the user terminal 111. However, needless to say, the present invention can be applied to a stand-alone system including only the user terminal 111 by storing data in a large-capacity storage medium such as a CD-ROM, a DVD library, and a large-capacity hard disk.

[0033]

As described above, according to the present invention,
Since access control is applied to the annotation, only an authorized user can edit and refer to the annotation, thereby improving security. Further, the editing history for the annotation can be automatically recorded and displayed in a list by a simple operation.
