【００１０】
【発明の実施の形態】
図１は、本発明の実施形態を示す利用モード変更指示に対する処理手順図である。
【００１１】
（Ｓ１）ユーザによる利用モード変更指示には、現在の許可モードＭｏｄｅ「ＵＥＮＤ，ＦＥＮＤ」を表示する。この許可モード表示には、各ファイルについて変更モードの状態を保持するデータ領域として、下記表に示すように２次元配列で用意する。
【００１２】
【表２】

【００１３】
この配列の第１の次元は、ユーザ区分に相当し、最も権限の強いユーザ区分に番号１を与え、以降には権限の１段階弱くなる毎にユーザ区分の通し番号２、３、…、ＵＥＮＤを与える。
【００１４】
同配列の第２の次元は、ファイルに対する「読出し」、「書込み」などの機能を、利用形態の場合の数（ＦＥＮＤ通り）だけ用意する。
【００１５】
（Ｓ２）利用モード変更を行うユーザがユーザ区分ｕｓｅｒと利用区分ｆｕｎｃを入力する。この利用モードの変更指示を受け付ける手段には、図２の場合と同様のユーザインタフェースを使用する。
【００１６】
このユーザによる入力形態は、１回の利用モード変更指示では１つのフラグのみがユーザによって操作され、同時に２つ以上のフラグが操作されないものとされ、いずれか１つのフラグをユーザが操作することでそのフラグがＯＮ（利用許可）とＯＦＦ（利用不許可）で交互に切り替えられる。
【００１７】
（Ｓ３）処理Ｓ２でユーザによって入力された変更区分Ｍｏｄｅ「ｕｓｅｒ，ｆｕｎｃ」の値をフラグ変数０ｆｌａｇに代入する。例えば、処理Ｓ２での入力内容でｕｓｅｒが前記表２のユーザ区分ＵＥＮＤで、ｆｕｎｃが利用方法１とすると、この２次元データが０ｆｌａｇに入力される。
【００１８】
（Ｓ４）処理Ｓ３で入力されたフラグ変数０ｆｌａｇの２次元配列に相当する利用モード（表２）の内容がＯＦＦか否かを判定する。
【００１９】
（Ｓ５）処理Ｓ４での判定がＯＦＦであれば、１からｕｓｅｒまでの各ユーザ区分ｕについて変更区分Ｍｏｄｅ「ｕ，ｆｕｎｃ」の値をＯＮにする。
【００２０】
例えば、処理Ｓ２での入力内容でｕｓｅｒが前記表２のユーザ区分ＵＥＮＤで、ｆｕｎｃが利用方法１であれば、当該区分をそれまでのＯＦＦからＯＮにすると共に、当該区分よりも権限の強いユーザ区分の全てをＯＮにし、利用区分の変更に不自然な設定を無くす。
【００２１】
（Ｓ６）処理Ｓ４での判定がＯＦＦでなければ、すなわちＯＮであれば、ｕｓｅｒからＵＥＮＤまでの各ユーザ区分について変更区分Ｍｏｄｅ「ｕ，ｆｕｎｃ」の値をＯＦＦにする。
【００２２】
例えば、処理Ｓ２での入力内容でｕｓｅｒが前記表２のユーザ区分１で、ｆｕｎｃが利用方法１であれば、当該区分をそれまでのＯＮからＯＦＦにすると共に、当該区分よりも権限の弱いユーザ区分の全てをＯＦＦにし、権限の弱いユーザ区分にＯＮが存在するという利用区分の変更に不自然な設定を無くす。
【００２３】
（Ｓ７）処理Ｓ５又は処理Ｓ６で変更された新しい許可モードＭｏｄｅ「ＵＥＮＤ，ＦＥＮＤ」の表示を行う。
【００２４】
【発明の効果】
以上のとおり、本発明によれば、ある区分のモード変更には、その利用形態の上位区分又は下位区分についても自動的に利用許可又は利用不許可にモード変更するようにしたため、ユーザによるモード変更指示に不自然な変更を無くすことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for changing a use permission mode (permission) for various data stored in a computer file or the like.
[0002]
[Prior art]
On computers used by multiple people, various data stored in files etc. can be used with "restrictions" not only by the owner (usually the user who stored the data) but also by other users. As a result, smooth data sharing among a plurality of users can be realized.
[0003]
In this case, for example, the user is divided into three categories of an owner, a user in the same group as the owner, and other users, and usage permission and non-permission can be set for each category. Furthermore, permission and non-permission can be set for each data usage mode such as data reading, writing, and execution even in the same category.
[0004]
FIG. 2 shows an example of a user interface for setting a conventional use permission mode. In the figure, the user category is divided into owner, user belonging to a group, and other users, and the usage mode can be set separately for reading, writing, and execution. Change the permission mode.
[0005]
[Problems to be solved by the invention]
In the conventional method for changing the use permission mode, the user can arbitrarily change the setting, so that there is a problem that an unnatural setting is accepted as it is.
[0006]
Here, the unnatural setting means that the “owner” is set to “write not allowed” and the other users are set to “write allowed” as in the setting example shown in Table 1 below. Strong authority is given to users with weak authority.
[0007]
[Table 1]

[0008]
An object of the present invention is to provide a change method that eliminates an unnatural setting for changing a use permission mode of data such as a file.
[0009]
[Means for Solving the Problems]
In the present invention, it is unnatural to change the mode of a certain category by automatically changing the mode to the use permission or the use disapproval for the upper (strong authority) or the lower (weak authority) classification of the use form. The following configuration,
Means for displaying a use permission mode for various data stored in a computer file or the like in a two-dimensional array of user classifications in the order of usage and strong authority;
A user interface for accepting an instruction to change the user category and the usage pattern for the display of the two-dimensional array;
Means for determining whether the current mode of the section instructed to change is use disapproval or use permission;
If the current mode is not permitted in the determination, the means for changing to usage permission and changing the authority more powerful than the user classification to usage permission;
If the current mode is permitted to be used in the determination, there is provided a means for changing to usage not permitted and changing a category having less authority than the user category to usage not permitted.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a processing procedure diagram for a use mode change instruction showing an embodiment of the present invention.
[0011]
(S1) The current permission mode Mode “UEND, FEND” is displayed in the usage mode change instruction by the user. In the permission mode display, a data area for holding the status of the change mode for each file is prepared in a two-dimensional array as shown in the following table.
[0012]
[Table 2]

[0013]
The first dimension of this array corresponds to the user section, and the number 1 is assigned to the most powerful user section, and thereafter, the user section serial numbers 2, 3,. give.
[0014]
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 usage mode (FEND).
[0015]
(S2) A user who changes the usage mode inputs a user category user and a usage category func. As a means for accepting this usage mode change instruction, the same user interface as in FIG. 2 is used.
[0016]
In this 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. When the user operates one of the flags, The flag is switched alternately between ON (use permission) and OFF (use disapproval).
[0017]
(S3) The value of the change category Mode “user, func” input by the user in step S2 is substituted into the flag variable 0flag. For example, if the user is the user classification UEND in Table 2 and the func is the usage method 1 in the input contents in the process S2, this two-dimensional data is input to 0flag.
[0018]
(S4) It is determined whether or not the content of the usage mode (Table 2) corresponding to the two-dimensional array of the flag variable 0flag input in the process S3 is OFF.
[0019]
(S5) If the determination in step S4 is OFF, the value of the change classification Mode “u, func” is turned ON for each user classification u from 1 to user.
[0020]
For example, if the user is UEND in Table 2 and the func is usage method 1 in the input contents in the process S2, the user is set to the ON from the previous OFF and the user is more powerful than the user Turn on all of the categories and eliminate unnatural settings for changing usage categories.
[0021]
(S6) If the determination in step S4 is not OFF, that is, if it is ON, the value of the change classification Mode “u, func” is turned OFF for each user classification from user to UEND.
[0022]
For example, if user is user category 1 in Table 2 and func is usage method 1 in the input contents in process S2, the user is turned off from the previous ON and the user is less authorized than that category. All of the categories are turned OFF, and an unnatural setting for changing the usage category that ON exists in the user category with weak authority is eliminated.
[0023]
(S7) The new permission mode Mode “UEND, FEND” changed in the process S5 or S6 is displayed.
[0024]
【The invention's effect】
As described above, according to the present invention, in order to change the mode of a certain category, the mode is automatically changed to use permission or non-use permission for the upper category or lower category of the usage mode. Unnatural changes to instructions can be eliminated.
