Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a personal computer or a word processor capable of canceling the protection setting for a document stored in a storage device corresponding to a storage name. .

[0002]

2. Description of the Related Art For example, a Japanese word processor (business machine) provided by the applicant of the present application has a data protection function called a document protection function. The outline of this function is a function to protect data so as not to delete the data or change the contents, and the operation is to display all the data in the document list and select the data to be protected one by one.

In general, there are a password function and a protection function as functions for protecting data and maintaining confidentiality.

For example, Japanese Patent Laid-Open No. 2-289078 discloses that the confidentiality of data is ensured by a document confidentiality holding device, and whether or not confidentiality is held is designated for each created document. Is what you need.

According to the method disclosed in Japanese Patent Laid-Open No. 2-287765, in order to maintain the confidentiality of data, either a user password or a password unique to the system is provided. By not calling it unless
It is to ensure confidentiality.

The system disclosed in Japanese Unexamined Patent Publication No. 5-73223 is a data management system for a floppy disk, and only a user who has written an identification code on the floppy disk can read / write the data. The user has a security mechanism in which the data is encrypted so that the contents of the data information stored in the floppy disk cannot be understood.

The one disclosed in Japanese Patent Laid-Open No. Hei 6-35970 provides a document retrieval system capable of facilitating registration and calling of a specific portion of a document requiring confidentiality and enhancing confidentiality. In this system, a password is attached in advance to a specific code for searching a specific part of a document, and by designating this specific code, the specific code and the password are stored in association with the specific part, and the specific code is stored. In the document retrieval system, a specific portion is called by designating at least a password when retrieving the portion. In other words, a bookmark with a password is created and attached to a document whose confidentiality is desired to be maintained, whereby the efficiency of search processing and the confidentiality of the document are maintained.

[0008]

However, in such a conventional technique, it is necessary to set data one by one, a special device is required, and it is necessary to provide a password set for each user. is there. Therefore, the user strongly feels that the operation of the protection control is very troublesome and inefficient, and strongly desires to propose an improvement measure.

That is, for example, Japanese Patent Laid-Open No. 289078/1990
In the publication, a special device is required, and it is necessary to specify whether or not confidentiality is maintained for each document, which is very troublesome.

Further, in Japanese Patent Laid-Open No. 2-287765, the password is limited to a user or a system.

According to Japanese Patent Laid-Open No. 5-73223, it is limited to a floppy disk and is effective only for individual users.

Japanese Unexamined Patent Publication (Kokai) No. 6-35970 aims to improve the efficiency of retrieval, and limits the password as a means for maintaining the confidentiality of a document.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an information processing apparatus capable of improving the operability of protection control and performing efficient confidentiality protection.

[0014]

In order to solve the above problems, an information processing apparatus according to claim 1 of the present invention has a searching means for searching stored document data, and a stored document. Protect setting means for canceling the protect setting for maintaining confidentiality of data, protect instructing means for instructing to release the protect setting, and when the protect setting is instructed by the protect instructing means, the search means The protect setting means is controlled so that the plurality of document data stored by the search means are searched to extract the document data containing the keyword, and the protect setting means extracts the document data. It is characterized in that it is provided with a control means for making a protection setting with respect to.

An information processing apparatus according to claim 2 of the present invention is
In order to solve the above-mentioned problems, in the structure of the above-mentioned claim 1, the document data to be searched by the search means is stored in the document, the document body corresponding to the stored name, or a part of the document body. It is characterized in that a search condition selection means for selecting from the above is provided, and the control means controls the search means so as to perform a search process on the document data selected and instructed by the search condition selection means.

An information processing apparatus according to claim 3 of the present invention is
In order to solve the above-mentioned problems, in the configuration of the above-mentioned claim 1, document selecting means for selecting the document data to be protected from the plurality of document data searched and extracted by the searching means is provided, and the control means is provided. Is characterized in that the protect setting means is controlled so that only the document data selected by the document selecting means is protected.

An information processing apparatus according to claim 4 of the present invention is
In order to solve the above-mentioned problems, a search means for searching stored document data, a protect setting means for canceling protection setting for keeping the stored document data confidential, and a document data And a document storage instruction means for instructing to store the document, and when the document storage instruction means instructs to store the document, the retrieval means and the protection setting means are controlled to newly store the document by the retrieval means. Search the data and extract keywords,
When the keyword is extracted, the protect setting means is provided with a control means for setting the protect on the document data.

[0018]

According to the structure of the first aspect, when the protect setting is instructed by the protect instructing means, the control device searches the stored document data and the protect setting for maintaining confidentiality. The protect setting means is controlled to perform a search for a plurality of document data stored by the search means to extract the document data containing the keyword, and the protect setting means extracts the document data. Protect the document data. As a result, a plurality of pieces of document data that have already been stored can be protected at once by simply inputting a keyword included in a document that should be kept confidential. Therefore, it is not necessary to specify confidentiality for each created document as in the past, and a user can efficiently use a special device or a password set for each user. The confidentiality of multiple documents can be secured.

According to the second aspect of the present invention, the search condition selecting means is provided, and the user uses the search condition selecting means to set the document data to be searched by the search means to the save name and save name of the document. It can be arbitrarily selected from the body of the corresponding document or a part of the body of the document. For example, saved name part of body text saved name + body text (keyword is included in either saved name or text) saved name + part of text body (keyword is included in either saved name or part of text) saved name × You can select from seven search conditions, such as the text (including the keyword in both the saved name and the text), the saved name x part of the text (including the keyword in both the saved name and part of the text). And
The control means controls the search means to perform the search processing on the document data selected and instructed by the search condition selection means. Therefore, in the case of batch processing using keywords, if the search target is only the saved name of, when there are many keywords in the text, but the saved name does not include keywords,
It is possible that the document data that should be kept confidential cannot be protected.
By selecting, it is possible to make detailed settings according to the contents of the document. Further, in this case, for the document data in which the keyword appears frequently, it is possible to increase the processing speed by selecting a part of the body of the document instead of the whole body of the document.

According to the structure of claim 3, the document selecting means is provided, and the user uses the document selecting means.
A document to be protected can be designated from a plurality of document data retrieved and extracted by the retrieval means. Then, the control unit controls the protect setting unit to set the protect only to the document data selected and designated by the document selecting unit. Therefore, the user can select the document data to be protected from the plurality of document data extracted based on the keyword, which is more effective than the case where all the document data including the keyword is protected. Protect settings can be set.

According to the structure of claim 4, when the document storage instructing means gives an instruction to save the document data, the control device searches the saved document data.
By controlling the protect setting means for performing the protect setting for maintaining confidentiality, the retrieval means searches the newly saved document data to extract the keyword, and when the keyword is extracted, The protect setting means causes the document data to be protected. As a result, by simply entering the keyword in advance, of the document data created and saved from now on,
Since protection is automatically set for items that require confidentiality, including keywords, there is no need to forget the protect setting, and the user can efficiently secure confidentiality of documents.

Next, a registration format of various data (document, external character, user dictionary, etc.) on the floppy disk 22 will be exemplified.

FIG. 3 shows the structure of a document file on the floppy disk 22. Usually, the registration area is divided into equal sizes called records, and numbers are sequentially assigned. This number is called a record number (hereinafter, the record number is abbreviated as R), and when a document is registered, the area is used for each record.

As shown in the figure, an index area for storing an index indicating information of registered data is provided at the head of the file, and following this index area,
A document registration area is formed. Here, R1 to R1
00 is assigned to the index area, and the document registration area is from R101.

In the index area, there are five kinds of information about the stored document, that is, a storage name, a flag indicating protection / non-protection, a password, a head record number,
Each information of the last record number is stored.

The above-mentioned save name represents the save name of the document given by the user when saving the document. The flag indicating the presence / absence of protection is a flag indicating whether or not protection is currently set in the stored document data. For example, if expressed in a 1-bit configuration, "0" indicates no protection, and "1" indicates protection. It may be protected. Further, the password is a user-specific secret code necessary for protection control of stored document data, and may be, for example, several digits or alphabets. The first record number is the first record number in which the document data is stored, and the last record number is the last record number in which the document data is stored.

Each of these pieces of information is stored in each of the five fields formed by dividing the addresses 0 to s-1 of one record in the index area into five fields. A storage name is stored in the field 1 of the addresses 0 to a-1, and a flag indicating the presence or absence of protection is stored in the field 2 of the addresses a to b-1. Also, field 3 from address b to c-1
, The password is stored in the field 4, and the start address is stored in the fields d to s in the field 4 from the addresses c to d-1.
The final address is stored in each field 5 up to -1.

Next, the operation of the document protect control in the word processor having the above configuration will be described. FIG. 4 shows a main flow of the document protection control operation. In S1, when the user issues a document protection control instruction using the keyboard 24, a selection screen as shown in FIG. 7 is displayed on the display device 26. For protection control,
There are five modes of "protection setting 1", "protection setting 2", "protection cancellation", "keyword setting", and "keyword cancellation". Here, the user selects a desired mode and inputs it from the keyboard 24.

The above-mentioned "protect setting 1" and "protect setting 2" are the same in that the password is added to the registered document data and the protect is set. The areas are different. In the former "Protect Setting 1", no work such as calling or editing of document data can be performed unless the added password is input, whereas in the latter "Protect Setting 2", the document can be called freely. However, the work such as data editing and update registration cannot be performed. In this case, whether to add a password can be freely selected.

Following the user selection in S1,
When it is confirmed that "Protect Setting 1" or "Protect Setting 2" has been selected (S2, S3), "Protect Setting Mode" is executed in S4, and "Protect Release" is confirmed. (S5),
In S6, the "protect release mode" is executed.
When it is confirmed that "keyword setting" is selected (S7), "keyword setting mode" is executed in S8, and when it is confirmed that "keyword cancellation" is selected (S9), "keyword setting mode" is selected in S10. The keyword release mode ”will be implemented.

First, FIG. 5 and FIG. 5 show the operation of the "protect setting mode" executed in S4 when the user selects "protect setting 1" or "protect setting 2" in the control mode selection of S1. It will be described based on the flowchart of FIG.

When the "protection setting mode" is started, first, a search condition is selected (S11), and a search condition selection screen as shown in FIG. 8 is displayed. The document search conditions are: condition 1; search for documents containing keywords in the save name condition 2; search for documents containing keywords in the document condition 3; part of the document (for example, the beginning of the document) )
Search for documents that contain keywords in Condition 4; Search for documents that contain the keyword in the saved name or document Condition 5; Search for documents that contain the keyword in the saved name or part of the document Condition 6; There are seven types of search: documents that include keywords in the saved name and documents Condition 7; documents that include keywords in the saved name and part of the document are searched.

First, the case where the user selects the condition 1 in S11 will be described. When it is confirmed that the condition 1 is selected in S12, a keyword (search word for searching a document for which protection control is performed) is next input (S13). Since condition 1 is selected here,
Keyword input 1 to enter a keyword for the saved name
Then, the keyword input 1 screen as shown in FIG. 9A is displayed. Here, the user inputs one keyword (keyword 1) for the storage name.

At this time, as a keyword, "19 **
As a document search method when "year" is input, first, a saved name including "1" is searched. If there is such document data, then “1” is followed by “9”, or character data “**” for two characters is entered after “9”, followed by “year”. To find out. It is possible to specify such a wild card.

When an arbitrary keyword is input by the user in S13, the document search 1 is executed (S1
4).

The search operation of the document search 1 is shown in the flowchart of FIG. First, "1" is assigned to the variable n (S
50). This n is a record number, and the number of storable items is 100 when the maximum storage capacity of one document data is three records, for example. The number of storable items changes depending on the data amount of each document to be saved. In this embodiment, it is assumed that 100 documents R1 to R100 can be stored at present.

Next, R1 of the index area shown in FIG.
Of the keyword 1 entered in S13 of FIG. 5 in the "storing name" portion of the range (field 1) from address 0 to a-1 of
Is searched for (S51). From the result of the search, it is judged whether or not the keyword 1 is included (S
52), if keyword 1 is included, proceed to S53,
If not included, the process proceeds to S56.

In S53, the storage name including the keyword 1 is stored in the RAM 28, and the search for the document data of R1 is completed by this, and the process proceeds to S54. R in this case
FIG. 11 shows an example of the storage procedure of the registration area of the AM 28. Since one keyword (keyword 1) for the storage name is specified in S13 of FIG. 5, the retrieved storage name is stored in the RAM registration area.

On the other hand, if it is determined in S52 that the keyword 1 is not included, the process proceeds to S56, and it is determined whether or not a character code is included in the field 1 of R1 in the index area shown in FIG. It is determined whether the document is not originally registered, not that the keyword 1 is not included. If the character code is not included in S56, it is determined that the document is not registered thereafter, and the search ends. on the other hand,
If the character code is included, the search for the document data of R1 is completed and the process proceeds to S54.

In S54, n + 1 is substituted for the variable n, and then the variable n is 101, that is, the storable number is 10
It is determined whether or not 0 searches have been completed (S55).
Then, if the variable n is not 101, the process returns to S51 to search for the next record number, that is, the document data of R2. On the other hand, while repeating the processes of S51 to S55, the search of 100 items which is the storable number is completed, and when it is determined that the variable n is 101, the search is completed.

When the processing of the document search 1 is completed in this way, the process proceeds to S15 in FIG. In S15, the RAM of FIG.
Display a list of saved names stored in the registration area, and
The document selection screen as shown in 2 is displayed.
Here, the user arbitrarily selects a document to be protected from the list of documents with the keyboard 24 and then presses the execute key (S16 in FIG. 6). Further, in this case, it is possible to collectively select all the extracted documents by designating a specific key on the keyboard 24.

If a document is selected and the execution key is pressed in S16, in S1 of the main flow of FIG.
It is confirmed whether "protect setting 1 mode" is selected or "protect setting 2 mode" is selected (S17). Then, as a result of the confirmation, "Protect setting 1
If "Mode" has been selected, a password input screen as shown in FIG. 13A is displayed, and password input is performed (S18). Here, the user enters the password. When the password is entered by the user, CP
U31 stores the entered password in the corresponding location of the floppy disk 2, in this case, the "password" location in field 3 of the index area shown in FIG.

When the input of the password is completed, the display as shown in FIG. 14 appears, and the function is executed by the execution key and the function is stopped by the release key (S19). At this time, S1
It is also possible to simultaneously display the storage name of the document selected in 6, the password, the function to be executed, and the like so that each item can be changed with a specific key.

In step S19, when the user presses the execute key, the protect setting 1 is selected first. Therefore, the protect is turned on for the designated document data so that the document cannot be called unless the password is input. . Then, "1" is stored in the "protected" section of field 2 of the index area shown in FIG. This completes the "protection setting 1 mode".

On the other hand, as a result of S17, if the "protection setting 2 mode" is selected in S1 of the main flow of FIG. 4, the password input screen as shown in FIG. Can select whether to input a password (S20).

If "YES" is selected here, FIG.
The password input screen as shown in (a) is displayed, and the password is input (S21). Here, when the password is input by the user, the CPU 31 stores the input password in the corresponding location of the floppy disk 2, in this case, the "password" location in the field 3 of the index area shown in FIG. . Then, the display is as shown in FIG. 14, and the function is executed by the execution key and the function is stopped by the release key (S22).

In S22, when the user presses the execute key, the protect setting 2 is selected first.
The specified document data is protected so that the document can be called but the editing work such as data update cannot be performed. Then, "2" is stored in the "protected" section of field 2 of the index area shown in FIG. This completes the "protection setting 2 mode".

On the other hand, if "NO" is selected in S20, S21 is skipped and the process proceeds to S22, in which the protection of protection setting 2 is turned ON. Then, "3" is stored in the "protected" section of field 2 of the index area shown in FIG. This completes the "protection setting 2 mode".

Next, a case where the user selects the condition 2 in the search condition selection in S11 of FIG. 5 will be described. S23
When it is confirmed that the condition 2 is selected in, the next keyword input is made (S24). Since the condition 2 is selected here, the keyword input 2 for inputting the keyword for the document is made, and the keyword 2 input screen as shown in FIG. 9B is displayed. Here, the user inputs one keyword for the document.

When the user inputs an arbitrary keyword in S24, the document search 2 is executed (S2).
5).

The search operation of the document search 2 is shown in the flowchart of FIG. First, "1" is assigned to the variable n (S
60). Then, the head record number stored in the "head record" part of the range (field 4) of the addresses c to d-1 of R1 is assigned to the variable x, and the addresses d to s- of the R1 are assigned to the variable y. The final record number stored in the "final record" portion of the range 1 (field 5) is substituted (S61).

Then, it is confirmed whether or not the head record number is assigned to the variable x (S62), and if the variable x has a character code, it is registered in the range of x to y, that is, R1 of the index area. Body of document (document registration area x ~
It is searched whether the keyword 2 is included in the (range of y) (S63).

From the result of the search, it is determined whether or not the keyword 2 is included (S64). If the keyword 1 is included, the process proceeds to S65. If not, the process skips S63 and proceeds to S66.

In S65, the storage name of the document including the keyword 2 is stored in the RAM 28, and the search for the document data of R1 is completed by this, and the process proceeds to S66. FIG. 11 shows an example of the storage procedure of the RAM registration area in this case. Since one keyword (keyword 2) for the document is designated in S23 of FIG. 5 described above, the retrieved storage name is stored in the area of the RAM registration area.

In S66, n + 1 is assigned to the variable n, and then the variable n is 101, that is, the storable number is 10
It is determined whether or not 0 searches have been completed (S67).
Then, if the variable n is not 101, the process returns to S61 to search for the next record number, that is, the document data of R2. On the other hand, while repeating the processes of S61 to S67, the search of 100 cases which is the number of storable cases is completed, and when it is determined that the variable n is 101, the search is completed.

Further, before it is confirmed that the variable n is 101, if there is no character code in the variable x in S62, no document is stored in the record of that record number. The search ends because no document is stored in the subsequent records.

When the processing of the document search 2 is completed in this way, the process proceeds to S15 in FIG. In S15, the RAM of FIG.
Display a list of saved names stored in the registration area, and
The document selection screen as shown in 2 is displayed.
The subsequent processing is the same as when the condition 1 is selected in S11.

Next, a case where the user selects the condition 3 in the search condition selection in S11 of FIG. 5 will be described. Here, the contents of the beginning of the document are searched as a part of the text. When it is confirmed that the condition 3 is selected in S26, the keyword is input next (S24). Since condition 2 is selected here,
It becomes the keyword input 2 for inputting the keyword for the document, and the keyword 2 input screen as shown in FIG. 9B is displayed. Here, the user inputs one keyword (keyword 2) for the document.

When the user inputs an arbitrary keyword in S24, the document search 3 is executed (S2).
7).

The search operation of the document search 3 is shown in the flowchart of FIG. First, "1" is assigned to the variable n (S
70). Next, the head record number stored in the "head record" part of the range (field 4) of the addresses c to d-1 of R1 is substituted for the variable x (S71).

Then, it is confirmed whether or not the leading record number is assigned to the variable x (S72). If the variable x has a character code, the keyword 2 is added to the leading portion of the body of the document registered in the range of x. Is searched for (S7
3).

From the result of the search, it is determined whether or not the keyword 2 is included (S74). If the keyword 2 is included, the process proceeds to S75. If the keyword 2 is not included, the process skips S75 and proceeds to S76.

In S75, the storage name of the document including the keyword 2 is stored in the RAM 28, and the search for the document data of R1 is completed by this, and the process proceeds to S76. FIG. 11 shows an example of the storage procedure of the RAM registration area in this case. Since one keyword (keyword 2) for the document is designated in S24 of FIG. 5 described above, the saved name retrieved is stored in the area of the RAM registration area.

In S76, n + 1 is assigned to the variable n, and then the variable n is 101, that is, 10 is the number of storable items.
It is determined whether or not 0 searches have been completed (S77).
If the variable n is not 101, the process returns to S71 to search for the next record number, that is, the document data of R2. On the other hand, while repeating the above-described processing of S71 to S77, the search of 100 cases, which is the number of storable cases, is completed, and when it is determined that the variable n is 101, the search is completed.

Further, before it is confirmed that the variable n is 101, if there is no character code in the variable x in S72, no document is stored in the record of that record number. The search ends because no document is stored in the subsequent records.

When the processing of the document search 3 is completed in this way, the process proceeds to S15 in FIG. 5, and the subsequent processing is the same as when the condition 1 is selected in S11.

Next, the case where the user selects the condition 4 or the condition 6 in the search condition selection in S11 of FIG. 5 will be described. When it is confirmed that the condition 4 or the condition 6 is selected in S27, the keyword is input next (S2
9). Here, since the condition 4 or the condition 6 is selected, the keyword input 3 for inputting the keyword for each of the storage name and the document is made, and the keyword 3 input screen as shown in FIG. 9C is displayed. Here, the user selects a keyword for each saved name and document (keyword 1
And keyword 2) will be input one by one.

When an arbitrary keyword is input by the user in S29, first, the same "document search 1" process as in S14 is performed to search for a document in which the saved name includes the keyword 1 (S30). Next, the same "document search 2" process as in S25 is performed to search for documents in which the keyword 2 is included (S31).

As a result of the search, when the keyword 1 is included, the saved name is stored in the area of the RAM registration area shown in FIG. 11. When the keyword 2 is included, the saved name is the same. It will be stored in the area of the RAM registration area. Then, based on the results of the search in S30 and S31, the stored names extracted in both are searched and stored in the area of the RAM registration area shown in FIG. 11 (S3).
2). At this time, the save name stored in the area is
It is erased from the areas of and.

Next, in S11, it is confirmed which search condition is selected (S33). As a result of confirmation, if condition 6 or condition 7 is selected, the process proceeds to step S34, condition 4
Alternatively, if the condition 5 is selected, the process proceeds to S35.

In S34, only the storage names extracted in S32 are displayed in a list. That is, only the storage name stored in the area of the RAM registration area shown in FIG. 11 is displayed.

On the other hand, in S35, S30, S31, S3
List all the saved names extracted in each table of 2. That is, in the RAM registration area shown in FIG.
Display all saved names stored in each area.

After that, the process proceeds to S16 in FIG. 6, and the subsequent processes are the same as when condition 1 is selected in S11.

Next, the case where the user selects the condition 5 or the condition 7 in the search condition selection in S11 of FIG. 5 will be described. When it is confirmed that the condition 5 or the condition 7 is selected in S36, the next keyword is input (S2).
9). Here, condition 5 or condition 7 becomes the keyword input 3 for inputting the saved name and the keyword for the selected document respectively, and the keyword 3 input screen as shown in FIG. 9C is displayed, and the user enters the keyword for the saved name. 1 and the keyword 2 for the document will be input.

When an arbitrary keyword is input by the user in S29, first, the same "document search 1" process as in S14 is performed to search for a document whose storage name includes the keyword 1 (S37). Next, the same "document search 3" process as in S27 is performed to search for a document in which the keyword 2 is included in the beginning of the document (S38).

When the search in S37 and S38 is completed in this way, the process proceeds to S33, where it is confirmed which search condition is selected in S11. If condition 5 is selected, the process proceeds to S35 and condition 7 is set. If it has been selected, the process proceeds to S34, and a display that meets the selected conditions is performed. The subsequent processing is the same as when the above-described search condition 4 or search condition 6 is selected, and therefore will be omitted.

Next, in the selection of the control mode in S1 of the main flow of FIG. 4, when the user specifies "protection cancellation", the operation of "protection cancellation mode" executed in S6 is shown in the flowchart of FIG. It will be described based on.

When the "protect release mode" is started, a password is first input (S80). Here, a password input screen as shown in FIG. 13B is displayed, and it is possible to select whether or not to input the password. This is because with regard to the document data whose protection is set to ON in the protect setting 2, both the document with the password added and the document without the password are mixed.

Next, it is judged whether or not the password is input in S80 (S81). If the password is input, the process proceeds to S82, and if not, the process proceeds to S92.

In S82, the input password is substituted for the variable x (S82). Next, 1 is substituted for the variable n (S84). This n is the record number shown in FIG. Next, it is searched whether the value stored in the "protected" portion of the range (field 2) of the addresses a to b-1 of R1 is 1 or more and 2 or less, that is, "1" or "2" ( S84). As described above, the value stored in the field 2 means the state of the protect setting, and “1” means the protect setting 1 (no work such as calling a document can be performed unless the password is input. ) Indicates that a password is present, "2" indicates a protect setting 2 (a document can be called but data editing cannot be performed), a password exists, and "3" indicates a protect setting 2 and no password exists. Incidentally, here, "-" is a state where protection is not applied.

The fact that a value other than "1" or "2" is stored in field 2 means that a password is added to the document data registered in the index area of that record number (that is, R1 here). That is, the search for the document data of R1 is completed, and the process proceeds to S87.

On the other hand, when "1" or "2" is stored, the password assigned to the variable x and R1
It is confirmed whether or not the password is the same as the password stored in the "password" part of the range (field 3) of the addresses b to c-1 (S85). If they are the same, the storage name stored in the field 1 of R1 is stored in the RAM 28 (S86), the search for the document data of R1 is completed, and the process proceeds to S87. If they are not the same, skip S86 and proceed to S87.

In S87, n + 1 is assigned to the variable n, and then the variable n is 101, that is, the storable number is 10
It is determined whether or not 0 searches have been completed (S88).
If the variable n is not 101, the process returns to S84 and the search for the next record number, that is, the document data of R2 is performed. On the other hand, if the search for 100 items, which is the number of storable items, is completed and it is determined that the variable n is 101, S8 is executed.
Proceed to 9.

On the other hand, if the password is not input in S80, it is determined that the password is not input in S81,
In step S92, 1 is assigned to the variable n. This n is shown in FIG.
The record number shown in.

Then, it is searched whether the value stored in the range (field 2) of the addresses a to b-1 of R1 is "3" (S93). If "3" is stored, the storage name stored in field 1 of R1 is RA.
After storing in M28 (S94), the process proceeds to S95. on the other hand,
If a value other than "3" is stored, it means that the value is not searched in this case (when the password is not input in S80), so S94 is skipped and the process proceeds to S95.
In S95, n + 1 is assigned to the variable n, and then the variable n
Is 101, that is, it is determined whether the search of 100, which is the number of storable items, has been completed (S96). If the variable n is not 101, the process returns to S93 to search for the next record number, that is, the document data of R2. On the other hand, when the search for 100 items, which is the number of storable items, is completed and it is determined that the variable n is 101, the process proceeds to S89.

In S89, the storage names stored in the RAM are displayed in a list, and the document selection screen as shown in FIG. 12 is displayed. Here, the user selects a document whose protection is to be released from the list of stored names by using the keyboard 24 and presses the execute key (S90). Further, in this case, it is possible to collectively select all the extracted documents by designating a specific key on the keyboard 24.

If a document is selected and the execute key is pressed in S90, the display as shown in FIG. 14 appears, and the execute key executes the function and the cancel key cancels the function (S91). S
In 91, when the user presses the execute key, the protection is canceled for the document of the selected save name,
The "protected" portion of the field 2 of the index area shown in FIG. 3 is changed from "1" or from "2" or "3" to "-". This completes the "protect release mode".

Next, in the selection of the control mode of S1 of the main flow of FIG. 4, when the user specifies the "keyword setting", the operation of the "keyword setting mode" carried out in S9 is shown in FIG. A description will be given based on the flowchart of 19. Note that, here, if the number of keywords that can be set in advance is 5, the set keywords are stored in the RAM registration area K1, K2, ... In a manner as shown in FIG.
Shall be stored in this order. In the RAM registration area, a keyword is stored in a field A from addresses 0 to a-1, a search condition is stored in a field B from addresses a to b-1, and a field C from addresses b to c-1.
The password is stored in, and the protect is stored in the field D from the address c to s-1.

When the "keyword setting mode" is started, first, 1 is substituted into the variable n (S100). This n
Indicates the registered keyword numbers K1, K2, ... Shown in FIG. Then address 0 of K1
It is searched whether a character code is stored in the "keyword" part of the range (a field) from a to a-1 (S1).
01).

As a result of the search, it is judged whether or not the character code is included (S102). If the character code is included, the process proceeds to S103, and if not included, S11 in FIG.
Go to 0 respectively.

First, when the character code is included, S10
The case of going to 3 will be described. The fact that the field A in K1 contains a character code means that one keyword has already been set in the keyword registration number K1. Therefore, in order to investigate the subsequent K2, next, n + 1 is substituted for the variable n (S1
03). Here, the variable n is the number of keywords that can be set 5
(S204). If the variable n is not 5, the process returns to S101 to continue the search, but if the variable n is 5, keyword setting becomes impossible and a message screen as shown in FIG. 21A is displayed. Here, the user can select whether to delete the already set keyword (S105).

At S106, "YES" or "NO".
If any of the above is selected and "NO" is selected, it is impossible to set the keyword, and the "keyword setting mode" ends.

On the other hand, if "YES" is selected, the keyword to be deleted is selected, and the process proceeds to S107, as shown in FIG.
A keyword selection screen as shown in (b) is displayed. Then, the user selects the keyword to be deleted using the keyboard 24 and presses the execute key (S107). When the execution key is pressed, the value of n of the registration number Kn of the selected keyword is substituted into the variable n (S108). Then, a final confirmation is made as to whether or not the deletion of the selected keyword may be executed (S109). If the deletion is to be executed, the process proceeds to S110 in FIG.
Returning to 06, this mode is terminated, or the keyword to be deleted is selected again.

Next, in the case where the character code is not included in S102 in FIG. 18, the process proceeds to S110 shown in FIG. 19, or the case where the keyword is deleted in S109 and the process proceeds to S110. explain.

The fact that the character code is not included in the field A of K1 (assuming that the keyword K1 is selected in S107) means that the keyword can be set, and the document saved after the keyword is set is protected. You will have to specify the necessary conditions to do so.

First, a condition selection screen as shown in FIG. 8 is displayed, and the user selects search conditions (S11).
0). Next, it is determined which condition is selected in S111 to S1.
It is confirmed in step 15 and the keyword is input according to the confirmed condition (S116 to S118). Note that this series of processes is S11, S12, S23, S26, S28, S3 described in the "protection setting mode" of FIGS.
Since it is the same as the series of operations of S6, S13, S24, and S29, detailed description thereof will be omitted.

When a keyword is input in S116, S117, or S118, the keyword is changed to CP.
U31 corresponds to a corresponding portion of the RAM 28, in this case, addresses 0 to a- of K1 in the RAM registration area shown in FIG.
It is stored in the range of 1 (field A) (S119).
If the keyword is stored, the protect content selection screen as shown in FIG. 21C is displayed, and the protect mode is selected (S120). Here, the user selects either protect setting 1 or protect setting 2.

Next, it is judged which of the protect setting 1 and the protect setting 2 is selected (S121). When the protect setting 1 is selected, the process proceeds to S122, and when the protect setting 2 is selected, the process proceeds to S125.

First, the protect setting 1 is selected and S12
The case of going to 2 will be described. When the protect setting 1 is selected, the CPU 31 has the RAM shown in FIG.
"1" is stored in the range of address c to s-1 of K1 in the registration area (field D) (S122). Next, FIG.
The password input screen as shown in 3 (a) is displayed, and the password is input (S123). Here, when the password is input, the CPU 31 causes the range of addresses b to c-1 of K1 in the RAM registration area shown in FIG. 20 (field C).
The entered password is stored in (S124).
This completes the "keyword setting mode".

Next, in S120, the protect setting 2
The case where is selected will be described. Protect setting 2
When is selected, a password input screen as shown in FIG. 13B is displayed, and a selection is made as to whether or not to input the password (S125). If “YES” is selected here, the CPU 31 causes the K in the RAM registration area shown in FIG.
"2" is stored in the range of address c to s-1 of 1 (field D) (S126), and the password is input (S1).
23). The subsequent steps are the same as when setting 1 is selected.

On the other hand, when "NO" is selected in S125, the CPU 31 sets K in the RAM registration area shown in FIG.
"3" is stored in the range of address c to s-1 (field D) of 1 (S127), S123 and S124 are skipped, and the "keyword setting mode" ends.

Then, in the "keyword setting mode" as described above, when the keyword is set in advance and the document is saved thereafter, the saved document is
The processing from keyword search to protection setting will be described with reference to the flowcharts of FIGS.

Here, as an example, it is assumed that a document is stored in the index area R2 of the floppy disk 22 shown in FIG. At this time, the record number saved at the same time is substituted into the variable n '(S130). When the document is saved, it is searched whether or not the keyword is set by the method described above in "keyword setting mode". 1 is substituted for the variable n (S131). This n is the registration number of the keyword shown in FIG.

Next, it is searched whether or not a character code is stored in the range (field A) of addresses 0 to a-1 of K1 (S132), and it is determined whether or not the character code is stored (S133). If the result of determination is that the character code is not stored in S133, this mode ends.
On the other hand, if the character code is stored, the process proceeds to S134, and the keyword stored in the range of address 0 to a-1 (field A) of K1 is substituted for the variable x (S134).

Next, the search condition is confirmed (S13).
5). The search condition stored in the range of address a to b-1 (field B) of K1 is confirmed, and the content is substituted for the variable y. The respective conditions mentioned here are the seven types of conditions described in the "protection setting mode" of FIG.

First, a case will be described in which "Condition 1 (search for a document whose storage name contains a keyword)" is set and it is confirmed in S136 that "Condition 1" is selected. First, the range of Rn ′ addresses 0 to a-1 (field 1), that is, the index area shown in FIG.
It is determined whether or not the keyword 1 is included in the "stored name" portion of the range (field 1) of the addresses 0 to a-1 of R2 (S137), and it is determined (S138 of FIG. 23). As a result of the determination, if the keyword 1 is included, the process proceeds to S139,
If not included, the process proceeds to S149.

First, if the keyword 1 is included and S13
If the process proceeds to 9, it is searched whether a character code is stored in the range (field C) of addresses b to c-1 of K1 (S139), and it is determined (S140). As a result of the determination, if the character code is stored, the process proceeds to S141, and if not, the process proceeds to S148.

The former case will be described. The fact that the character code is stored in the range of addresses b to c-1 of K1 means that the password is set at the same time as the keyword setting, and the password is set to the range of addresses b to c-1 of R2. It is substituted in (field 3) (S141). That is, it is stored in the "password" portion of the field 3 of R2 in the index area shown in FIG. Next, the value stored in the range (field D) of the addresses c to d-1 of K1 is substituted into the variable z (S142). In the range of addresses c to d-1 of K1,
As described in "Keyword setting mode", the protection setting method is shown. It is confirmed whether the variable z is "1" (S143).

If it is "1", the address ab of R2-b-
“1” is stored in the range of 1 (field 2) (S14
4) The protect is turned on (S145). In this case, the protection is turned on (protection setting 1) so that no work such as calling the document can be performed unless the password is input.

On the other hand, if it is not "1" in S143, "2" is stored in the range of addresses a to b-1 of R2 (S146), and the protection is turned on (S147). In this case, the document can be called, but the protect is turned on so that the data editing work cannot be performed (protect setting 2).

If the result of determination in S140 is that there is no character code, that is, no password has been set, "3" is stored in the range of addresses a to b-1 of R2 (S148), and the routine proceeds to S147. , Protect ON.

On the other hand, if the result of the search in S138 is that the keyword is not included, n + 1 is substituted for the variable n (S149). This is for searching the keyword set next. Here, it is determined whether the variable n is "5" which is the number of keywords that can be set (S15).
0). If the variable n is "5", this mode ends,
If not "5", the process returns to S132 of FIG. 22 and the remaining keywords are searched.

Next, a case will be described in which "Condition 2 (search for a document containing a keyword in a document)" is set and it is confirmed in S151 that "Condition 2" is selected.

When it is confirmed in S151 that "condition 2" has been selected, the flow proceeds to S152 in FIG. 24, and the range from the address c to d-1 of R2 (field 4) to R2 in the index area shown in FIG. It is searched whether the keyword 2 is included in the range (field 5) of the addresses d to s-1.

After the search, the process returns to S138 in FIG. 23, and the subsequent steps are the same as when the condition 1 was set.

Then, "condition 3 (search for a document in which a part of the document contains a keyword)" is set, and S1 is set.
A case where it is confirmed in 53 that "condition 3" has been selected will be described. In addition, although it is described as "a part in the document" in this condition, this is described in the protect setting,
Since "the beginning of the document" is given as an example, the same applies this time.

When it is confirmed in S153 that "condition 3" has been selected, the flow proceeds to S154 in FIG. 25, where the start record number of the first record number stored in the range (field 4) of addresses c to d-1 of R2 is selected. It is searched whether the area contains the keyword 2.

After the search, the process returns to S138 in FIG. 23, and the subsequent steps are the same as when the condition 1 was set.

Then, "condition 4 (search for documents containing keywords in the save name or document)" or "condition 5 (search for documents containing keywords in the save name or part of the document)" Is set and it is confirmed in S155 that "condition 4" or "condition 5" is selected.

When it is confirmed that "condition 4" or "condition 5" is selected in S155, the process proceeds to S156 in FIG.
It is searched whether the keyword 1 is included in the range of R2 (0 to a-1) (S156), and it is determined (S157). The processing of S156 and S157 is S13 in the case of condition 1.
7, the same as S138.

As a result of the determination, if the keyword 1 is included, the process proceeds to S139 in FIG. 23, and if it is not included, the S1 is performed.
Proceed to 58. In the latter case, it is confirmed whether the variable y is "condition 4" (S158). And if "condition 4", R
2 addresses c to d-1 range (field 4) to R2
It is searched whether or not the keyword 2 is included in the range (field 5) of the addresses d to s-1 (S159). The process of S159 is the same as the process of S152 in the case of condition 2. If the variable y is not "condition 4", it is searched whether or not the keyword 2 is included in the area of the head record number stored in the range of addresses c to d-1 of R2 (S160).

After both of them have been searched, the process returns to S138 in FIG. 23, and the subsequent steps are the same as when the condition 1 was set.

Then, "condition 6 (search for documents whose keywords are included in the saved name and document)" or "condition 7 (search documents whose keywords are included in the saved name and part of the document) ] Is set and it is confirmed in S161 that “condition 6” or “condition 7” is selected.

When it is confirmed in S161 that "condition 6" or "condition 7" has been selected, the process proceeds to S162 in FIG.
It is searched whether the keyword 1 is included in the range (field 1) of the addresses 0 to a-1 of R2 (S162), and it is determined (S163). The processes of S162 and S163 are also the same as S137 and S138 in the case of condition 1.

As a result of the determination, if the keyword is included, the process proceeds to S164, and if not included, the process proceeds to S139 of FIG. In the former case, it is confirmed whether the variable y is "condition 6" (S164). If "condition 6", the keyword 2 is added to the range of addresses c to d-1 of R2 (field 4) to the range of addresses d to s-1 of R2 (field 5).
Is searched for (S165). This S165
The process of is the same as the process of S152 in the case of condition 2. If the variable y is not “condition 6”, the address c of R2
It is searched whether or not the keyword 2 is included in the area of the first record number stored in the range of d-1 (S16).
6).

After both of them have been searched, the process returns to S138 of FIG. 23, and thereafter, it is the same as the case where the condition 1 is set.

Finally, in the selection of the control mode of S1 in the main flow of FIG. 4, the user performs "keyword release".
The operation of the "keyword cancellation mode" executed in S10 when "" is specified will be described with reference to the flowchart of FIG.

When the operation of "keyword cancellation mode" is started, a list of preset keywords is displayed (S170). At this time, a keyword selection screen as shown in FIG. 29 is displayed. Here, the user selects a keyword whose setting is to be canceled (S171). When the execute key is pressed, a screen as shown in FIG. 30 is displayed and it is confirmed whether or not the keyword setting may be canceled (S17).
2). Here, when the execution key is pressed, the setting of the selected keyword is canceled and deleted from the keyword registration area (S173). This completes the "keyword release mode". When the release key is pressed in S172, the process returns to S171 and the selection is performed again.

As described above, in the word processor of the present embodiment, the user simply designates "protect setting 1" or "protect setting 2" and inputs the keyword included in the confidential document, and the data is already saved. You can set protect settings for all documents at once, copy and delete,
It is possible to secure the safety of the document by prohibiting modification and prevent the leakage of information confidentiality by prohibiting the reading of the document.

In the protection setting operation as described above, it is not necessary to specify whether or not confidentiality is maintained for each document to be created, a special device is required, and the operation is set for each user. Without providing a password, the user can keep confidentiality of multiple documents efficiently and simply.

Moreover, since the search condition in the protect control mode can be selected from the above seven search conditions (1) to (3), an efficient keyword search can be performed by setting the condition according to the stored data. ,
The protection control can be performed with higher efficiency.

In addition, all the documents (storing names) including the keywords extracted by the search are collectively protected.
Or, of course, it is possible to cancel, but from the extracted document, the user can select the protection setting or the one to cancel, so it is more efficient,
Effective protection control can be performed.

By simply inputting a keyword in advance, among the document data to be created and stored,
Since protection is automatically set for items that require confidentiality, including keywords, there is no need to forget the protection setting. This allows the user to more efficiently and reliably keep the document confidential.

Further, in this embodiment, a password is used for setting or canceling the protection. Therefore, by performing the protection control by designating the password, the double-structure protection control by the password can be performed on the document including the specific keyword, so that the confidentiality can be more surely maintained.

Further, when the protection processing is executed and the protection control of the protected document is released, the stored protected document is called, the password is inputted and the document is extracted to protect it. It is supposed to be released. Therefore, it is possible to release the protection in this way for a document for which the confidentiality period has passed and share or utilize the document as a public document.

If a keyword is set and the newly saved document data includes this keyword, a password already used in other document data is copied and the protection control is performed with this password. Are to be implemented. Therefore, it is possible to save the trouble of inputting the password one by one and efficiently enter the password.

Further, in this word processor, it is possible to extract a document that matches the specified condition contents by performing a wildcard search for the keyword. Therefore, when the number of documents is large, it is necessary to efficiently extract the documents, but this allows the target document to be read quickly even if there is only ambiguous storage.

Although not particularly described in the present embodiment, when the password is updated and changed with respect to the set password, it is already stored in the temporary storage means 6 and the non-volatile storage means 11. In the case where the keyword entered later by the input means 3 is included in the text or the saved name for the document for which the password is set,
By automatically updating to the new password only when the old password is entered and the passwords match, the password can be changed efficiently. This allows you to change your password if you want,
Even if the password is leaked for confidentiality,
It can be handled by changing the password.

When a keyword is input from the input means 3 and the calling / storing means 8 calls a document stored in the temporary storage means 6 and the non-volatile storage means 11, the logical search of the search means 10 is designated for the keyword. However, by extracting the documents that match the specified condition contents, a logical search of keywords can be performed when reading the documents, and only the target document can be efficiently extracted by various logical search formats. , Protect control can be executed. Also in this case, when the number of documents is large, it is necessary to efficiently extract the documents, and the documents can be quickly read even if the target document has only ambiguous memory.

[0149]

As described above, the information processing apparatus according to the first aspect of the present invention has a searching means for searching the stored document data and a confidentiality protection for the stored document data. Protect setting means for canceling the protect setting, protect instructing means for instructing to cancel the protect setting, and when the protect setting is instructed by the protect instructing means, the search means and the protect setting means are controlled, The search means searches the plurality of document data stored to extract the document data containing the keyword, and the protect setting means sets the protect on the extracted document data. And a control means.

This makes it possible to protect a plurality of document data that have already been stored at once by simply inputting a keyword included in the document that should be kept confidential. Therefore, it is not necessary to specify confidentiality for each created document as in the past, and a user can efficiently use a special device or a password set for each user. This has the effect of ensuring the confidentiality of multiple documents.

An information processing apparatus according to claim 2 of the present invention is
As described above, in the structure of claim 1, a search for selecting the document data to be searched by the search means from the save name of the document, the body of the document corresponding to the save name, or a part of the body of the document. Condition selection means is provided, and the control means is configured to control the search means so as to perform a search process on the document data selected and instructed by the search condition selection means.

As a result, in the case of batch processing using keywords, if the search target is only the saved name, the saved name does not include the keyword even though the text contains many keywords. In some cases, it may be possible to protect the document data that should be kept confidential, but it is possible to make detailed settings according to the contents of the document. Further, in this case, for document data in which keywords are likely to appear frequently, it is possible to increase the processing speed by selecting a part of the text of the document instead of the full text of the document. Play.

An information processing apparatus according to claim 3 of the present invention is
As described above, in the structure of claim 1, the document selecting means for selecting the document data to be protected from the plurality of document data searched and extracted by the searching means is provided, and the control means is the document. The protect setting means is controlled so that only the document data selected by the selecting means is protected.

As a result, the user can select the document data to be protected from the plurality of document data extracted based on the keywords, so that compared to the case where all the document data including the keywords are protected. This has the effect of enabling more effective protection settings.
