Abstract

PURPOSE:To make the information enigmatic when directly read from the memory medium and to keep the confidentiality of the information, by changing the order of information according to the key code when the information is stored on a memory medium. CONSTITUTION:When the secret protection key is inputted from a keyboard 4, the key code inputted from keyboard 4 is stored at the key code storage area, and the disposition order of the information in a temporary memory 12 is changed according to the key code. The change of disposition order is done in the following manner: firstly setting the first column as a starting point, letters of 1st column and the 2nd column and letters of 3rd column and 4th column are exchanged each other respectively; then setting the 2nd column as the starting point, the letters of 2nd column and 3rd column, and letters of 4th column and 5th column are exchanged each other respectively. The same procedure is repeated by setting the starting point by one column behind each time. The number of repetition of this exchanging process is designated by the first 2 digit of the key code. Following this, letter exchange toward the row direction is done. The number of repetition is specified by the last 2 digit of the key code.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to an information processing device that is optimal for +IA confidential maintenance of a series of information created by a food processor or the like for use in the field of industrial application.

(b) Word processors are rapidly becoming popular as part of the latest OA boom in conventional technology. Many of these word processors often use external storage media such as floppy disks to save documents once created and prepare for reuse.

Confidentiality protection for these devices 1a function is not equipped, or even if it is equipped, the key code must be entered in the directory section of the floppy disk and it must match the code entered by the user. There are many simple things like making it unreadable (rNew published by Kyoikusha Co., Ltd.)

~P230').

? 9. Problems to be solved by the invention However, in terms of protecting the confidentiality of literary professionals who can create L using the above-mentioned conventional method, they are almost defenseless.

That is, as long as one obtains a storage medium such as a floppy disk in which the created literature is stored, it is possible to completely read out the contents of the storage medium using a general-purpose computer or the like.

B) A flat membrane for solving the problem The present invention was made in view of the problem, and when writing a series of information on a storage medium, a series of circumstances occur depending on the key code. It is an object of the present invention to provide an information processing device that duplicates and reads out the arrangement order of the information based on a key code when reading out the information sickle.

(E) Effect Even if the information written on the storage medium using this type of device +1 is read using another general-purpose computer, the order of arrangement of the information is different, so the information cannot be read properly. It becomes difficult to understand.

(f) Practical Example A practical example of the present invention applied to a word processor is shown below.

FIG. 1 and FIG. fJ2 show the external appearance and node square configuration of the present embodiment device.

゛ '@1 In Figure 1, (1) is the main casing, and the main casing contains a main control unit consisting of a microprocessor, circuits such as temporary memory and peripheral circuits, a floppy disk device (2), and a CRT device. (3) is incorporated.

! 4) ti keyboard, which has a group of keys (5) for inputting data input/editing commands and a secret protection key (5).
6). +7) is a printer that prints the created document.

Also shown in FIG. 2 is a main control section consisting of a microprocessor, etc., and the main control section controls the following sections based on a built-in control block. +13 is semiconductor R
This is a temporary memory consisting of AM (, Fungmu access memory), etc., and created document information etc. are stored in this memory.

When the data is inputted from the keyboard 141, the main control unit (lυ) stores the data (hereinafter simply referred to as ``sleep'') in the temporary memory memo 'JU in the order of input, and the editing command for print instruction is inputted from the keyboard +41. Then, the information stored in the temporary storage memory D is printed out from the printer +71.The main control unit (11) also prints out the information stored in the temporary storage memory u on the CRT device fi1 (31).
to be displayed.

Furthermore, the main control unit (lυ) loads the data in the temporary memory U into the floppy disk device (2) based on the control program indicated by the command from the keyboard +41.
The information previously stored in the floppy disk device (2) is transferred to the temporary memory memo IJ+13.

FIG. 6 shows a control program for writing information in the temporary storage memory u7J to the floppy disk device 12+.

First, in step S1, the keypad storage area preset by the control program is cleared to zero. If the keyboard is not pressed in step S2, the processing will proceed to step 54.

In step S6, when a key code is input from the keyboard 14), when a pray key code is input, the manually inputted key code is entered as a key code.

Store in the head storage area. When the S6 step is completed, the process returns to S.
Proceed to step 4.

In step S4, the arrangement order of information in the temporary storage memory 02 is changed according to the key code stored in the key code storage area.

Below is an example of the order of pray order,
The above key code is assumed to be a 4-digit decimal number, and is arranged in 4 rows x 5 columns on the CR7 screen 113 in the temporary memory memory uz as shown in FIG. 5 (-). It is assumed that information is stored in the order in which it is arranged.

(1) In a certain situation, start from the 1st row and move the 1st and 2nd rows, the 6th row, the 4th row, the 4th row, and the '44J5th row. Swap characters. The arrangement state of information changed by the replacement process shown in FIG. 5(C) is shown.

Thereafter, in the same way, skip the first row by one row, insert adjacent letters, and repeat the previous work. It should be noted that the number of times of the previous work is the number specified by the first two digits of the key code.

Next, characters are transposed in the line direction.

In terms of layout, 1
First, use the first line as the starting position, and swap the characters on the 11th line and the 2nd line, and the characters on the 6th and 4th lines, then use the 2nd line as the starting position, and change the characters to the 2nd line and fJIJ3 line. Do this by switching the letters on the eyes.

In addition, the number of times the direction of praying can be changed is shown in the bottom 2 of the key code above.
It shall be the number of times specified in digits.

Now, assuming that the key code is "0201", Figure 5 (
The information in a) is rearranged as shown in Fig. fJ5 (d) and becomes meaningless.

When step S4 is completed, the process proceeds to step S5,
In the prayer step, the information arranged in the 54-step process is stored in the floppy disk device (2) in accordance with the arranged order, and the process ends.

Next Vζ Based on the flowchart in Figure 4, the information stored in the floppy disk device (2) is stored in the temporary memory memo IJ.
The process of reading data to u21 will be explained.

First, in step S11, the system waits for a key code to be input from the keyboard +41 to keyboard +4), and when the pray key code is input, the input key code is stored in the key code storage@ area.

Next, in step S12, information corresponding to the key input from the keyboard 141 is read from the floppy disk device (2) onto the temporary memory surface.

When the sequence of prayers is completed, in step 515, the arrangement order of the information in the temporary storage memory U is duplicated based on the key code stored in the key code storage area g, and the process ends.

The desired duplication operation can be performed by performing the opposite process to that performed in step 84 described above.

For example, suppose that information arranged as shown in FIG. 5(d) is currently stored in the temporary storage memory U, and that the key code @0201 is stored in the key code storage chain. Swap the characters in the first and second lines (
Figure 5(C)), then the second row with the second row as the starting position.
The characters in the 6th column and the 6th column, and the characters in the 4th column and the 5th column are exchanged (FIG. 5(b)). Furthermore, by using the first column as the starting position and replacing the characters in the first and second columns, and the sixth and fourth columns, respectively, it is possible to create a plurality of characters in the arrangement order shown in Figure 5 (-). Monkey.

Please note that the above key code is not "0201", but for example "
Q 1 (] 1 ”, the arrangement order of the information stored in the floppy disk device 12) cannot be duplicated.

(g) Effects of the Invention As described above, the information processing device of the present invention changes the arrangement order of a series of enemies when storing them on a storage medium such as a floppy disk device. Mediator 9
Even if you were to read out the Naokatarujo Kijohan, it would be meaningless, so it is very useful in terms of maintaining the confidentiality of information.
