A control unit that performs various controls in the terminal device 100 by using various arithmetic devices such as U, a display unit that displays images by using display devices such as a liquid crystal display and various displays, and the like that performs various displays as a user interface. Preferably.

The storage server 300 also comprises a storage unit 30 for realizing the storage process 4 and an access restriction unit 31 for realizing the access restriction process 5.

The image data generation unit 10 in this embodiment reads an image and generates digital image data.
For example, a scanner can be used. As a scanner, flatbed, sheet through, automatic document feeder,
A double-sided document reading device or the like can be used, but there is no particular limitation.

The image data generated by the image data generator 10 is information obtained by digitizing an electric signal generated by image optical scanning, and includes JPEG, Tiff, BM.
Image format such as P, OCR for the image format
It contains textual information obtained by processing.

Digital image data generated by reading the original image is stored in a memory (not shown).

In the present invention, how to generate the access restriction information is important. In the first aspect, the image data analysis unit 11 analyzes the marking of the open section and the access restriction information generation unit. At twelve,
This is to generate access restriction information based on the analysis result in the image data analysis unit 11.

The first mode is a mode in which the input sheet shown in FIG. 3 is used, and the input sheet shown in FIG. 3 can be read together with the document to be managed. When the input sheet is read, first, the marking of the open section described on the input sheet is analyzed. The input sheet shown in FIG. 3 is provided with a check box for selecting a disclosure target. In the example shown in the figure, "No restrictions", "Managers", "General Affairs Division", "Development Department", and "Registration Group" are listed as disclosure targets, the "Registration Group" column is checked, and the "Group ID" is "A
"01" is entered. In addition, the input sheet is provided with an entry field for the input person ID and a check box for the registration server (which is the storage server 300) as required entry items. Such other required input items can be provided as necessary as information for determining the attribute of the image data.

The analysis of the marking of the open section is performed by analyzing the information and check marks written in the marking area of the input sheet by OCR or the like.

On the basis of the analysis result of the image data analysis section 11, the access restriction information generation section 12 generates information of "registration group" and "group ID" of "A01" as access restriction information.

The second mode is a mode in which the input sheet shown in FIG. 4 is used, and the mode shown in FIG. 4 is a case where a check box for selecting a disclosure target is not provided.

In this case, the processing according to the processing flow shown in FIG. 5 is performed. That is, in the image data analysis unit 11, after the image is read (S1), it is determined whether or not there is a marking of the open section in the image data of the read document (S2). Since the sheet shown in Fig. 4 does not have the marking of the open section, it is judged that there is no marking of the open section,
Manuscript type marking is performed (S3).

The analysis of the marking of the document type is performed by analyzing the information and the check mark written in the marking area of the input sheet by OCR or the like. In the sheet shown in FIG. 4, the document types are minutes A, minutes B, slips,
There are check boxes for photos, medical records, and advertisements, and minutes A are checked. Therefore, the document type is determined to be "minutes A" (S4).

The access restriction information generation unit 11 refers to the disclosure section table in which the document type is associated with the disclosure section in advance (S5), and generates the access limitation information (S6).

FIG. 6 shows an example of the open category table in which the document type and the open category are associated in advance. Referring to the table in FIG. 6, the publication type corresponding to the “minutes A” is “publication only for members of group 1”, and this is generated as access restriction information.

The third mode is a case where an input sheet is not used, and in this case as well, it is judged whether or not there is a marking of the open section in the image data of the read document, and it is judged that there is no marking of the open section. That is the case.

Therefore, when generating the access restriction information, first, the image data analysis unit 11 extracts the profile of the image data. That is, the image data profile of the read document is extracted and analyzed.

Extraction of the profile of the image data is performed by
Predetermined characters (eg, watermark characters such as “hidden” and “confidential”), character positions (eg, watermark characters and date positions), or ruled line positions (eg, ruled line intersections) It is preferable that at least one is analyzed and acquired as an image data profile.

The profile of the image data thus obtained is registered in advance in association with the disclosure category. FIG. 7 shows a table of the registration example.

The coordinates in FIG. 7 are determined by the values obtained by reading the position of the read image data from the coordinate axis assuming the coordinate axis as shown in FIG.

Therefore, the profile of the image data is discriminated by the above analysis, and based on the discriminated profile, the "disclosure category" is selected from the "disclosure category" and the "image data profile" in the table of FIG. 7 registered in advance. To decide.

In this way, the access restriction information can be generated.

In this way, it is possible to easily set the disclosure category of the document only by the scanner and the document to be read, from the disclosure category previously associated with the image profile.

In the above description, in the access restriction information generation unit, the access restriction information is used together with the document type, the machine ID of the machine that has read the document, the network address, and the personal identification I of the operator who has read the document.
It is also preferable that at least one of D, read date and time, read page number, read image data format, thumbnail image or image data profile is generated and used as index information. This is because the access restriction information is generated more reliably.

In the present invention, the access restriction information generated as described above is information for managing access to a document (image information), and includes a user or a user group and reading, editing, deleting of the user. This is information for restricting whether or not to print out. The user includes a specific terminal.

The access restriction information and the image data generated as described above are stored in the storage unit 30 of the storage server 300. At this time, the access restriction information stored in the storage unit 30 and the image data are stored in association with each other. In this way, the access restriction information and the image data are saved in the storage unit 30, and the storage of the management document is completed.

Although not shown, the storage server 300 includes a control unit, which controls the operation of the entire storage server 300 and the access status of the terminal device 100 connected to the storage server 300 and the storage server 300. It is preferable.

It is also preferable that the storage server 300 has a communication means such as a network card and a network interface, and that data can be transmitted and received by communicating with the terminal device 100 via the network 200.

The network 200 is a line connecting the terminal device 100 and the storage server 300 so that they can communicate with each other. As such a network 200, LA
Various networks such as N, WAN, and the Internet can be used and are not particularly limited. Network 20
The form of 0 may be wired or wireless.

As described above, by storing the access restriction information and the image data in the storage unit 30, after the storage of the management document is completed, the user requests access to the image data of the management document. In that case, the access restriction unit 31 restricts access based on the access restriction information generated as described above.

Access restriction by the access restriction unit 31 will be described below.

First, the storage unit 30 of the system from the user
