Abstract

PROBLEM TO BE SOLVED: To eliminate unnatural change by automatically changing a mode to utilization permission or utilization non-permission even for the superior section or inferior section of the utilization form for the mode change of a certain section. SOLUTION: In a processing S1, a utilization permission mode is displayed by the two-dimensional array of the utilization form and user sections in the descending order of the strength of a right. A user interface receives the change instruction of one section of the utilization form and the user section for the display of a two-dimensional array. In the processing S4, whether the present mode of the change-instructed section is the utilization non-permission or the utilization permission is judged. When the present mode is the utilization non- permission in the judgement, in the processing S5, it is changed to the utilization permission and the section where the right is stronger than the user section is changed to the utilization permission. When the present mode is the utilization permission in the judgement, in the processing S6, it is changed to the utilization non-permission and the section where the right is weaker than the user section is changed to the utilization non-permission.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a method of changing a use permission mode (permission) for various data stored in a file or the like of a computer.

[0002]

2. Description of the Related Art Computers used by a plurality of persons include:
Various types of data stored in files, etc. can be used with “restricted” by not only the owner (usually, the user who stored the data) but also other users, so that multiple users can use the data smoothly. Data sharing.

[0003] In this case, for example, the user is
The user is divided into three groups, a user in the same group as the owner and another user, and use permission and non-permission can be set for each section. Further, permission and non-permission can be set for each data use mode such as data reading, writing, and execution in the same section.

FIG. 2 shows an example of a conventional user interface for setting a use permission mode. In the figure, the user classification is divided into owner, user belonging to the group, and other users, and the use mode can be set separately for reading, writing, and execution. Change the permission mode.

[0005]

In the conventional method of changing the use permission mode, the user can arbitrarily change the setting.
There is a problem that an unnatural setting in operation is accepted as it is.

Here, the unnatural setting is, as shown in a setting example shown in Table 1 below, where "owner" is set to "write prohibited" and the other users are set to "write permitted".
Users with lesser authority than the main user have stronger authority.

[0007]

[Table 1]

[0008] An object of the present invention is to provide a change method for eliminating an unnatural setting for changing a use permission mode of data such as a file.

[0009]

According to the present invention, when the mode of a certain category is changed, the use of the upper (higher authority) or lower (lower authority) category is automatically permitted or disabled. By changing the mode to permission, unnatural changes are eliminated, and the following configuration, the use permission mode for various data stored in computer files, etc. Means for displaying in a two-dimensional array, a user interface for accepting an instruction to change one of the user divisions and the use mode for the display of the two-dimensional array, and whether the current mode of the division instructed to be used is not permitted or permitted. Means, and if the current mode indicates that the use is not permitted, the mode is changed to use permission and a category having a higher authority than the user category is used. Means for changing to a permitted state, and means for changing to a non-permitted state if the current mode indicates that the current mode is permitted and to a non-permitted state for a section having a lower authority than the user section. I do.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a processing procedure diagram for a use mode change instruction according to an embodiment of the present invention.

(S1) The use mode change instruction from the user includes the current permission mode Mode “UEND, FEN”.
D "is displayed. In the permission mode display, a two-dimensional array is prepared as a data area for holding the state of the change mode for each file as shown in the following table.

[0012]

[Table 2]

The first dimension of this array corresponds to the user division, and the number 1 is assigned to the user division having the highest authority, and thereafter, the serial numbers 2, 3,... , UEND.

In the second dimension of the array, functions such as "read" and "write" for a file are prepared in the same number as in the case of the use mode (FEND).

(S2) The user who changes the use mode inputs the user category user and the use category func. The means for receiving the instruction to change the use mode uses the same user interface as in FIG.

In the input mode by the user, only one flag is operated by the user in one use mode change instruction, and two or more flags are not operated at the same time, and one of the flags is operated by the user. By doing so, the flag is alternately switched between ON (use permission) and OFF (use non-permission).

(S3) In step S2, the value of the change mode "user, func" input by the user is assigned to the flag variable 0flag. For example, in the input contents in the processing S2, the user is the user classification UEND in Table 2 above.
If func is the usage method 1, this two-dimensional data is input to 0flag.

(S4) Usage mode corresponding to a two-dimensional array of flag variables 0flag input in process S3 (Table 2)
It is determined whether or not the content is OFF.

(S5) If the determination in step S4 is OFF, the value of the change section Mode "u, func" is turned ON for each user section u from 1 to user.

For example, in the input contents in the process S2, the user
Is the user category UEND in Table 2 above, and if func is usage method 1, the relevant category is changed from OFF to ON, and all of the user categories having higher authority than the relevant category are turned ON. Eliminate unnatural settings for changes.

(S6) If the judgment in the process S4 is not OFF, that is, if it is ON, the change section Mode “u, fu” for each user section from user to UEND.
nc ”is turned off.

For example, in the input contents in the process S2, the user
Is user class 1 in Table 2 above, and if func is usage method 1, the class is changed from ON to OFF, and all the user classes having authority lower than the class are set to O.
FF is set, and an unnatural setting for changing the use category such that ON is present in a user category with a weak authority is eliminated.

(S7) The new permission mode Mode “UEEND, FEND” changed in step S5 or step S6 is displayed.

[0024]

As described above, according to the present invention, when the mode is changed in a certain section, the mode is automatically changed to the use permission or the use non-permission for the upper section or the lower section of the use mode. In addition, it is possible to eliminate an unnatural change in the mode change instruction from the user.

Claims (1)

[Claims] 1. A means for displaying a use permission mode for various data stored in a file or the like of a computer in a two-dimensional array of user categories in the order of use and a category having a strong authority, and a user category for the display of the two-dimensional array.
