Abstract

PURPOSE:To manage only a part of an original document as a secret without processing the original document by setting the prescribed area of document information to be a secret area, and storing it at the time to input pass word information. CONSTITUTION:An area setting means 9 which sets and stores the prescribed area of the document information at the time of the registration of pass word information, and an output controlling means 10 which refers to the setting of the area setting means 9 and turns a part of the document information into an invisible state when the inputted pass word information does not coincide with the outputted pass word information of the document information in the case to output the document information are provided. Thus, when the pass word information does not coincide at the time to output the document information, a part of the document information is outputted in the invisible state on the basis of area information set at the time of the registration, and in the case where the secret of only a part of the document is desired to keep, it becomes unnecessary to store the original document after processing it, and the identity of contents can be secured, and in addition, a storage area can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic file system for electronically processing documents.

[Prior Art] In conventional electronic file systems, in order to maintain the confidentiality of stored documents, password information 7 is set when storing document information consisting of image information and code information, and password information 7 is set when storing document information consisting of image information and code information. When displaying document information, a method is adopted in which document information cannot be displayed unless preset password information is input.

[Problems to be Solved by the Invention] However, in the conventional example described above, if it is desired to protect only the negative part of one document information as confidential and make the other parts public, it is necessary to create a document with the confidential part deleted, Two document information, including the original document with password information set, must be stored separately, which results in loss of content identity in the same document and requires more storage space. There were drawbacks.

An object of the present invention is to provide an electronic file system that allows only a portion of an original document to be managed as confidential without modifying the original document.

[Means for Solving the Problems] The present invention includes a storage means for storing a plurality of pieces of document information, an input means for inputting password information, and an output means for outputting the document information stored in the storage means based on input of the password information. In an electronic file system having an output means,
An area setting means for setting and storing a predetermined area of the document information when registering the password information, and when the input password information does not match the password information of the document information to be output when outputting the document information. The apparatus is characterized by comprising an output control means for making part of the document information invisible by referring to the settings of the area setting means.

[Operation] In the present invention, when the inputted password information does not match the password information of the document information to be output when text information is output, based on the area information set at the time of registering this password information.

Part of the document information will be output in an invisible state.

Therefore, if you want to keep only part of a document confidential,
There is no need to process and memorize original documents,
It is possible to ensure the sameness of content in the same document and save storage space.

[Embodiment] FIG. 1 is a block diagram showing the configuration of an electronic file system according to an embodiment of the present invention.

This electronic file system consists of a CRTI which is a high-resolution display, a video RAM 2 that displays images on the CRTI, a BMU 3 that controls data transfer between each memory and other devices, a printing device 4, and a printing device 4. Interface 5 of device 4 and optical disk device 6
, a controller 7 of this optical disk device 6, a keyboard 8 for inputting data such as password information, and a CRT.
A pointing device 9 that indicates coordinates on I, a cptrio that performs main control of the system, a program memory 11, an image memory 12, and a hard disk 13.
, a companding circuit 14 that compresses and expands image data, and C
It has an I10 bus 15 that communicates between PU10 and each circuit element.

FIG. 2 is a flowchart illustrating the password information setting process in the electronic file system of this embodiment.

Here, an optical disk on which a plurality of document images, which are document information, have already been stored is set in the optical disk device t6.

First, a document for which password information is to be set is selected using the keyboard 8 (S l 6). Next, the document image of the selected document is read from the optical disk device 6 into the image memory 12 (S 17), and then the document image is read into the image memory 12 (S 17). Display the above document image on the CRTI (51
B) Use the pointing device 9 to specify an area of the document image displayed on the CRTl that you want to make a confidential document.S19) Enter password information for the specified area using the keyboard 8 (520).

As a result, the input password information and coordinate information indicating the confidential bond city are stored in a predetermined storage area of the optical disk device 6 (521), and the setting of the password information is completed.

FIG. 3 is a schematic document image z9 showing a specific example of the document image 29 and password information 31 displayed on the CRTI in the password information setting process such as 1 or more.
indicates the height, weight, etc. of an individual, and the pointing device 9 points to the area of the weight value (broken line 3 in the figure).
0) is specified and stored as one confidential area. Further, as the password information 31, rABCJ is input.

FIG. 4 is a flowchart illustrating the process of displaying a document image with password information set in the electronic file system of this embodiment.

Here, an optical disk that has already stored a plurality of document images, password information, and confidential area information is set in the optical disk device 6.

Therefore, first select the document you want to display using the keyboard 8 (322), and read the selected document image into the image memory 12 using the optical disk device 6 (S23).
, then input the password information corresponding to the selected document from the keyboard 8 (524), read the password information and confidential area information set for the selected document into the main body from the optical disk device 6 (S25), and If the input password information and the password information read from the optical disk device 6 do not match (S26), the confidential area portion determined from the a-sensitive area information in the document image on the image memory 12 is Invisibility processing such as filling is performed (527), and finally the document image in the image memory llh is displayed on the CRTI (32B).

Finish the process.

Further, in 526, if the input password information and the password information read from the optical disk device 6 match, the above-mentioned invisible processing is not performed and the original document image is displayed on the CRTI and the processing ends ( 5
28).

In the setting example shown in Figure 3 above, as shown in Figure 5,
When rABcJ is input as password information, all image information 29 is displayed, but as shown in FIG. 6, when rDEFJ is input as password information, it does not match the password read from optical disk device 6. Therefore, the image information 29 is displayed with the confidential area 30 filled in.

As explained above, in this embodiment, if there is no input for a part of one document image that matches the password information set in advance, by displaying the part of the document image as invisible, a new password can be created. Without creating a document with part of the document image mentioned above deleted,
Circumstances include placing restrictions on the display of a portion of a document.

In the above embodiment, when inputting the area where the document is to be made invisible, the document image is displayed on the CRTI and inputted using the pointing device 9. Depending on the die used, similar processing can be performed without displaying the document image on the CRTI.

In addition, in the above embodiment, the process of filling out the image area was used to make the document invisible, but if the process makes it difficult to obtain information on confidential parts of the document, it is possible to erase the image area, hatch, create a mosaic pattern, etc. The same processing as in the above embodiment can also be performed using the processing method.

Further, in the above embodiment, the coordinate information of the AT secret area information document image of the document is used, but it is also possible to use a document image representing the secret area of the 5 documents itself.

Further, in this case, the process of making the document image invisible may include a method of superimposing the original document image and a document image representing the confidential area of the document itself.

In addition, although the invisible processing is performed on the image memory 12, it is also possible to perform the invisible processing when transferring one document image from the image memory 12 to the VRAM 2. In this way, if the password information is incorrect, the correct password information If input again, it is possible to read out the document image from the image memory without reading out the document image from the optical disc 6, so that the time required to display one document is shortened.

Furthermore, in the above embodiment, when displaying one document image,
We used character input from the keyboard as password information, but if the information can identify the operator of the system, it is possible to enter the name of the operating manual at the beginning of system use and use it as password information, the operator's handwriting, fingerprints, etc. It is also possible to adopt a method of using a voice print or the like as password information.

Furthermore, even in a character processing device that uses character code information as document information instead of a document image, the optical disc 6
By storing character code information in , the same effect as in the above embodiment can be obtained.

[Effects of the Invention] According to the present invention, when it is desired to keep only a part of a document to be output confidential, there is no need to process and store the original document, and the sameness of content in the same document can be ensured. This also has the effect of saving storage space.
