Abstract

PURPOSE:To improve the handleability of an information processor by holding an inputted password until the information processing task of the password is through and to attain an access to a file or a directory to which a password coincident with the input password in the same way as the file or the directory to which no password is added. CONSTITUTION:An information processor can have accesses to plural files or directories registered into a storage 111 together with a passwords with input of another password coincident with the former one. Then a password inputted at start of an information processing task is held (112) until this task is through. Then a file or a directory to which a password coincident with an input password is added can receive an access like the file or the directory to which no password is added during the information processing task. Thus it is not required to repetitively input the passwords during an information processing task. Then the handleability is improved for a secret protection file or a directory.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing apparatus, and particularly to security protection of files or directories registered in the information processing apparatus by a plurality of users.

[Conventional technology]

Information processing devices such as word processors and personal computers are often shared by an unspecified number of users, and it is necessary to protect the security of files or directories registered by each user in a storage device. To this end, a file or directory that requires security protection is assigned a password and registered in the storage device, and thereafter this file or directory cannot be accessed unless a password that matches the password is entered. Security measures have been proposed to prevent this.

[Problem to be solved by the invention]

However, in an information processing device equipped with such a security protection method, the password for a security file or directory must be repeatedly entered each time the security file or directory is accessed, which impedes the handling of the security file or directory. There is a bad problem.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the handling of security-protected files or directories that are password-protected.

[Means to solve the problem]

In order to achieve this objective, the present invention makes it possible to access a plurality of files or directories registered in a storage device with a password by inputting a password that matches the password. The information processing device retains the password entered at the start of information processing work until the end of the information processing work, and during the information processing work, files or directories with passwords that match the input password are saved as passwords. It is characterized by the provision of security protection measures that allow it to be accessed in the same way as files or directories that are not marked.

[Effect]

The security protection means retains the password entered at the start of information processing work until the end of the information processing work, and protects files or directories with a password that matches the input password without a password. Since it can be accessed in the same way as a file or directory, there is no need to repeatedly enter the password during the information processing operation.

Processing to display on the display device 7 is executed. .

The file management unit 9 stores the external storage device 111.
It manages files and directories stored in , and has functions such as registering and deleting files, creating and deleting directories, and setting and canceling passwords. Then, according to instructions given from the document creation/editing processing section 4 and file operation processing section 5, processing is executed on files and directories stored in the primary external storage device 11.1.

The hand data management section 10 includes the secondary external storage device 11
It reads and writes data to and from the external storage medium 112b set to 2, and operates according to instructions from the file operation processing section 5 and the password storage storage medium creation processing section 6.

Next, the details of the control processing mainly performed by the file operation processing section 5 for the file operation will be explained in more detail with reference to FIG.

When the file operation processing section 5 is activated by the basic control processing section 3, it first performs processing to obtain a password (step 101).

The details of this password acquisition process 101 will be explained in detail with reference to FIG. First, the secondary external recording device 112
A check is made to see if the external storage medium 112b is set (step 501). External record/ha medium 11
2b is set, the external storage medium 11
Step 502) instructing the data management unit 1o to read password data from the password storage area of 2b, and reading out the password data. Processing is performed to store it in the management variable area 71 (step 503). The secondary external storage device 112 has an external memory.
)2 medium 112b is not set, a process is performed to create display data requesting input of a password from the input device 1 and display it on the display device 8 (step 504). The password input is monitored (step 505). If a password is input from the input device 1, the input password data is stored in the password management variable area (50
3). If no password is input, a NULL code is stored in the password management variable area 71 (step 506).

After acquiring the password in this way, the file operation processing section 5 controls the file management section 9 to search for files and directories stored in the primary external storage device 111, and searches for files and directories stored in the primary external storage device 111, such as the file-file shown in FIG. Display data for displaying the list on the display 8 is created. The file list table 72 in FIG. 7 shows the display data created at this time, and the data in the file list table 72 corresponds one-to-one to the file list displayed on the display screen. There is. While the file list is being displayed, it waits for an input from the input device 1 (step 102).

When the input device 1 is operated and an input code is given, the input code is analyzed (step 103), and if the input code is a "cursor movement" code, the cursor is moved in the specified direction (step 104). ). "
If it is a "target designation" code, the line where the cursor is displayed is displayed in black and white inverted, and the index value of the file list table 72 corresponding to the file in the cursor display line is stored in the target designation variable area 73. If it is a "target cancellation" code, if the line where the cursor is displayed is displayed in reverse black and white, the black and white reverse display is canceled, "0" is stored in the target specification variable area 73, and the target is specified. (step 105).

If it is a code such as "r update or copy", check the value of the target specification variable area 73 (step 106), "
O'' (there is no target specification), a buzzer sound is output to notify the user that there is an incorrect input (step 107), and if it is other than rQJ (there is a target specification), the target specification variable area 73 is The password data in the file list table 72 using the value as an index is compared with the password data stored in the password management variable area 71 (step 108). If the password data in the file list table 72 and the password in the password management variable area 71 match, the specified process is performed on the specified file. for example, "
In the case of "update" processing, the document creation/editing processing section 4 is activated to enable editing processing to be performed on the data of the specified file (step 109). If there is a mismatch, all the password data in the file list table 72 whose index is the value of the target specified variable area 73 is N.
It is checked whether the ULL code (password has not been set) is entered (step 110). Then, if all codes are NULL codes, the specified process is performed on the specified file (step 109), and NU
If it is not an LL code, an error message indicating that the process cannot be performed is displayed, the value of the target specification variable area 73 is set to "0", and the process returns to wait for input (step 111). “Password settings/
If it is a "release" code, password setting processing/password cancellation processing is performed (step 112). In this process, when an instruction to set a password is input, - the file management unit 9 is instructed to set a password in the password management variable area 71 for a specified file or directory in the external storage device 111; , assign a password to the specified file or directory. If it is an instruction input for password release, - external storage device 11
The file management section 9 is instructed to remove the password for the specified file or directory in 1, and the password for the specified file or directory is removed. If it is an "end" code, a NULL code is stored in the password management variable area 71 to invalidate the password acquired and stored at the start of the work, and the basic control processing unit 3 ends the processing of the work. The processing by the file operation processing section 5 is then terminated (step 113).

When the basic control processing unit 3 receives the notification, it creates basic menu screen display data and displays it to enable selection and input of the next work menu.

Next, user operations when using this information processing device will be described.

When setting a password for a file or directory to be protected, select "3" on the basic menu by operating keys on the input device 1, and input the designation of the file or directory to be protected and the password to be set for it. This password is
It is also stored in the external storage medium 112b of No. 12.

- When processing a password-protected file or directory stored in the external storage device 111, the external storage medium 112b in which the password has been registered (stored) is transferred to the secondary external storage device 112. , and perform an input operation to select "2" from the basic menu. As a result, the display 8 displays the primary external storage device 1.
A list of names of files and directories stored in 11 is displayed.

Therefore, by specifying the file or directory to be processed and the content of the processing work, files and directories with matching passwords can be processed in the same way as files and directories without passwords.

When the processing work is completed, by inputting "Finish", the files and directories to which the password has been assigned are placed in a secure state. In order to maintain this security state, the user must transfer the external storage medium 112b set in the secondary external storage device 112 to the secondary external storage device 112.
Just take it out and store it.

Of course, when starting work on a secure file, the user may enter a password using keys on the input device 1 to enable processing on files and directories that match the password.

〔Effect of the invention〕

As described above, according to the information processing apparatus of the present invention, if a password is input at the start of an information processing operation, all files or directories to which a password matching the password is assigned are targeted during the processing operation. processing operations can be performed, and the handling of secure files or directories is improved.

Further, when the password is stored in an external storage medium such as a floppy disk, the password can be entered by simply attaching and removing the external storage medium to the external storage device.

There is no need to remember passwords, and you are freed from the hassle of remembering passwords.
