Abstract

PURPOSE:To keep secret of data by registering information indicating that a part of text data is output inhibit data and displaying this data only at the time of coincidence of a password. CONSTITUTION:When a file is selected, it is discriminated whether an AS (all secret) code 44 exists or not. If it exists, input of a password is prompted, and the file is opened only when the inputted password coincides with contents of a password memory 48. If it does not exist, it is discriminated whether a PS (partial secret) code 46 exists or not; and when the code 46 exists, the file is opened after data from PS start data 52 to PS end data 54 in a text data memory area 42 are processed. When a PS release key is operated, input of a password is prompted; and when the inputted password coincides with contents of the password memory 48, processed and outputted data is outputted again in the original state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document editing device, and particularly to a document editing device that can treat a portion of data in a text memory as confidential.

[Prior Art] Conventionally, in document editing apparatuses used in offices and the like, one document editing apparatus is sometimes shared by a plurality of people. For example, it was convenient for people in charge of sales-related work, general affairs-related work, human resources-related work, etc. to convert letters from other people into their own business letters.

However, there are cases where it is desirable to keep some data secret from other business personnel, such as sales-related price information or personnel information.

In this case, if documents containing confidential data are saved on individual floppy disks for each person in charge, it is unlikely that the confidential data will be leaked to the outside, but it is better to save the documents in a common file (hard disk or RAM). Document files containing some confidential data were often saved in a common file, as access speed for the next editing task would be faster if there was one.

In this way, if a document containing confidential data is saved in a common file, anyone can access, view, or print this file, and the confidential data will not be leaked to the outside. In addition, there is a risk that the contents of the file may be changed.

Conventional measures to prevent such harmful effects include:
A password unique to the person in charge is registered in advance for each document file, and when accessing a certain document in the common file, all data will be accessed unless there is an input that matches the password registered in advance. reading was prohibited.

[Problems to be Solved by the Invention] As described above, if the configuration is such that the expansion of document files is prohibited unless there is an input that matches the registered password, leakage of confidential data and unintended changes to document files can be avoided. However, this method significantly deteriorated the reuse efficiency of common files and document files.

In other words, even if confidential data exists only in part of the document file, all of the document data cannot be read unless the passwords match, so the person in charge is forced to enter the data from the beginning. It is from.

Therefore, the purpose of the present invention is to prohibit the output of only that secret data, or To provide a document editing device which enables the diversion of document data other than secret data by processing and outputting the data so that the secret data is not faithfully output.

[Means for Solving the Problems] The present invention comprises an input means for inputting data, a text memory for storing the input text data, and an output means for outputting the text I/data in the text memory to the outside. In a document editing device having a text memory, a password memory stores a password for prohibiting the output of a part of text data in a file for each file, and a password memory for prohibiting the output of a part of text data in a file. A memory for output-prohibited data that stores data specifying the text data of the section in correspondence with each file, and a password corresponding to the specified file unless there is an input that matches the password in the memory when in the text data output mode. , control means for inhibiting the output of a part of the text data in the file, or for processing and controlling the output of the text data, based on the data in the output-prohibited data memory.

[Function] In addition to registering the password 1 in advance in the password memory in association with the document file, it is also possible to output data specifying some text 1 data that should be prohibited from being output in the document file. Register it in the prohibited data memory.

When accessing a document file in which this password and data for specifying output prohibited data are registered in advance, only when there is an input that matches the registered password.
All data of the specified document file will be output.

On the other hand, if there is no input that matches the registered password,
Based on the data in the memory for output-prohibited data, the output (display, printing, etc.) of some text/data in the file is prohibited, or some text/data is not output faithfully. As such, we will process this data and control the output. As a result, it becomes possible to maintain the confidentiality of the data. Furthermore, data other than this output prohibited data is allowed to be output, so this data can be reused for editing work.
Compared to conventional methods that prohibit the output of all data other than confidential data, the work efficiency of document editing is significantly improved.

[Embodiment] Hereinafter, an embodiment in which the present invention is applied to a single-language word processor will be specifically described with reference to the drawings.

As shown in FIG. 3 showing the appearance of the embodiment device, a word processor main body (hereinafter abbreviated as word processor main body) 10
A floppy disk driver (hereinafter abbreviated as FDD)] 2 and a hard disk driver (hereinafter abbreviated as HDD) 14 are built in, respectively, as external storage devices. Further, a keyboard (K/B) unit 16 as an input device and a CRT device 18 as a display device are connected to the word processor main body]0.

Next, the control circuit within the word processor main body 10 will be explained with reference to the block diagram of FIG.

The CPU 20 is in charge of all controls of this word processor, and in particular, in the case of this embodiment, has an arithmetic function for performing arithmetic processing on data whose output has been designated in advance as prohibited. Furthermore, a ROM 22 storing a control program and a RAM 24 as an internal storage device are provided, both of which are connected to the CPU 20 via a data path 26 and an address bus 28.

The input data from the K/B unit 16 is sent to the CPU.
Input interface (input/I/
F) 30 is provided, and this input 1/F30 is similarly connected to the CPU 20 via the data path 26 and address bus 28.
etc. are connected to. Further, the CRT device 18, FD
D12 and HDD I. CRT・I/F32, FDD-1/F34 and HDD・
I/F36 is provided, and each of these 1/F32, 3436
Similarly, it is connected to the CPU 20 and the like via a data path 26 and an address bus 28.

Next, the data stored in the RAM 24 will be explained with reference to FIG.

A part of the storage area of the RAM 24 is provided with a file data memory area 40 and a text data memory area 42 (not shown in the figure).

In the file data memory area 40, in addition to storing the document file name, file type, file size, file start address, etc. as in the past, all secret l-(AS) flag 44, part secret (
PS) flag 46 and password memory 48 are provided. and said K/B unit]6
When the full-text secret mode (AS mode) is set, the AS flag 44 is set under the control of the CPU 20. On the other hand, when the partial secret mode (PS mode) is set in the same way, the PS flag 46 is set. is sesoto. Further, when either one of the flags 44 and 46 is set, a password for releasing the secret is registered in the password memory 48.

Further, when the PS mode is set, in addition to registering the password, data for specifying the data to be kept secret is registered. In this embodiment, PS start data 52 and PS 6% end data 54 are registered at corresponding addresses in the text data memory area 42 as addresses before and after the secret data 50 shown in FIG. Ru.

Next, the setting of the AS mode or PS mode will be explained with reference to the flowchart of FIG.

When the editing mode is set by the operator, an editing routine is first carried out in step Sl (hereinafter simply referred to as S, and similarly performed), and AS/PS selection based on a specific command input is performed in S2. It is determined whether or not there was. If the determination result in S2 is that there is no mode selection, and if it is determined in S7 that the end key has not been operated, the editing routine in S1 is continued.

Here, if it is determined in S2 that the mode has been selected, an AS/PS setting routine is executed in the next step 83. In this Luzhin, CPU20 is ROM2
Based on the program in 2, the CRT device 18'' AS
This is done by controlling the display of a screen that prompts you to set the mode or PS mode. When AS mode is set using the cursor key, execution key, etc. (S4・YES)
In step S5, a password setting routine is executed under the control of the CPU 20, prompting the CRT device 8 to input a desired password (eg, 8 characters or less).

If a password has been input (S6, YES), it is determined in S7 whether or not the end key has been operated. At this time, the end key has not been pressed yet, so
The process returns to the editing routine at S1 again, and the document can now be edited.

Also, if the end key is operated in S1, S
At step 8, the user is prompted to specify a file in which to save the document. Then, at 89 after finishing this file, R
A data storage operation to AM24 is performed. Here, A
．． When the S mode is set and a corresponding password is entered, the edited text data is stored in the text data memory area 42 in the RAM 24, while the A. A flag indicating that the S mode has been designated is set in the AS flag 44, and the input password is stored in the password memory 48.

On the other hand, if there is no AS mode setting in S4,
In the next step 81-0, it is determined whether the PS mode has been set. 7. If the PS mode is not set, it is determined in S 1 1 whether a cancel key (not shown) has been operated, and if 1.Y has been created, this mode is canceled. Return to S1.

The editing routine can then be continued until the end key is operated. Also, when the end key is operated following the operation of the cancel key, S1- to S2S7 are red and S8, S8 and S7 are red.
At step 9, the document file is stored in the RAM 24.

If it is determined in S10 that the PS mode has been set, 3 1. At step 2, a password setting routine is executed, and a screen is displayed on the CRT device 18 prompting the user to enter a password. If it is determined at 31B that a password has been input, the PS position designation mode is set to 1 at the next step 314. At this time, when specifying a position to prohibit the output of a specific part of the data in the document data, it is convenient to display the document data on the CRT device]8, so according to the control of the CPU 20, The document data being edited is displayed. And S ]
．． In step 5, use the command key, cursor key, etc.
The start and end positions of the data whose output should be prohibited are specified. If it is determined in S16 that the designation of the PS position has been completed, the process returns to S2. If you want to save data with the PS mode set, press the end key in S1 (S7 YES), specify the file in 88 as in the AS mode, and then save the data to the RAM 24 in S9. Executes data storage.

At this time, if the PS mode is specified, the 1B password is stored in the password memory 48, and a flag indicating that the PS mode is specified is set in the PS flag 46.
In addition, as shown in FIG. 1, the text data, PS start data 52, and PS end data 54 are stored in the text data memory area 42 in a manner that corresponds to each output prohibition data and is truncated.

Next, based on the input from K/B unit 16, the operator
The operation of accessing the text 1 file in the RAM 24 via the CPU 20 and opening the designated file will be described with reference to FIG.

First, in S2], when a file is selected, S
At step 22, it is determined whether or not an AS code is set.

If an AS code is set, 3 2. 3, a screen prompting you to enter a password is displayed. After this password input operation (S24), it is determined in S25 whether or not the password matches a password registered in advance in the password memory 48. Then, only if there is an input that matches the registered password, the file can be opened in the next step 326. On the other hand, if there is no input that matches the registered password, the message that the password must be repeatedly entered remains displayed, and the file open operation is not performed unless the passwords match. Therefore, a person who does not know the password cannot ozone the specified file, and the confidentiality of the specified file is maintained. On the other hand, a person who does not know this password cannot use any data other than confidential data in the specified file during document editing work.

Next, a case where file selection is made in S21 and AS mode 1 is not set but PS mode is set will be explained. If this PS mode is set (
S22・No. 327/YES), each data in the text data memory area 42 from the PS start data 52 to the PS end data 54 is processed in 328, and then the file is opened in S26 and transferred to the CRT device]8. indicate. Here, in the processing at 828, each data search in the text data memory area 42 is performed by the CPU 20, and when the PS head data 52 is searched, each subsequent data is searched by the CPU 20.
For example, in the calculation processing unit of the data, 4
Processing to add 0H data is performed. This data addition process is continued until the PS end data 54 in the text data memory area 42 is detected.

In this way, when opening a file in which the PS mode is set, the output prohibited data specified in advance is processed and displayed on the CRT device 18 as data different from the faithful data. Therefore, not only the confidentiality of the output prohibited data is maintained, but also non-secrecy data other than the output prohibited data can be effectively used during document editing.

Here, in S29, a PS release key (not shown) is pressed.
If has been operated, the determination result in S30 is YES, and the process moves to S31.

[S3] Under the control of the CPU 20, a screen prompting the user to enter a password is displayed on the CRT device 18. If a password is input in S32, it is determined in 33B whether or not it matches the registered password 1- in the password memory 48. Then, only when it is determined in S10 that there is an input that matches the registered password, each data from the PS start data 52 to the PS end data 54 is imported into the CPU 20 again in the next step 334. Then, the 40H data is subtracted from each data and displayed on the CRT device 18. As a result, for a person who knows this password, the output prohibition command for the previously specified output prohibited data is canceled, and all data in the specified file can be displayed as is on the CRT device 18.

On the other hand, if the key input in S29 is the Bling 1 key, the judgment result in S35 is YES, and the next 33
The file selected in step 6 is printed on the printing paper.

Further, if a key other than the Ps release key or the print key is operated in S29, a process corresponding to the operated key is executed in S37.

Note that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.

For example, in the above embodiment, the settings for AS/PS mode 1.
Although this is carried out by selecting a mode based on the specific command 1 data during execution of the editing routine, it may also be carried out after the editing operation is completed after operating the end key. On this occasion,
Without specifying confidential data by its address, a blanket command that prohibits output of all data using numerical input keys, such as salaries, etc., after editing is completed, or in the case of personnel-related documents. It is also possible to issue a blanket command to prohibit all input data of names using proper nouns from being outputted. That is, the input for prohibiting the output of some data in the text data is not necessarily performed by specifying the address, but may be performed by the type of input key, word registration, or the like.

In addition, in the above embodiment, only the case where AS mode/PS-e-F are set independently is explained, but for example, if different passwords are set for AS mode and PS mode, these two modes can be used for one file. You may also make settings. Further, in the above embodiment, the case where the present invention is applied to files stored in the RAM 22 has been described, but it is similarly applicable to various files such as a floppy disk or a hard disk. Further, the present invention may be applied to print output instead of display.

[Effects of the Invention] As explained below, according to the present invention, it is registered in advance that some data of text and data is output prohibited data, and when there is no input that matches the registered password, prohibits data output of output prohibited data,
Alternatively, by processing and outputting this data, the confidentiality of the output-prohibited data is maintained, and data other than that data can be effectively used as text data when editing a document.
