The hardware configuration of the information processing terminal according to the present invention will be described with reference to FIG.
In FIG. 7, reference numeral 1 denotes an information processing device such as a portable terminal, which includes a storage unit 2, a processing unit (CPU) 3, a storage unit remaining amount detection unit 4, a keyword search unit 5, and a display unit. 6, a standby detection unit 7, a deletion candidate data file presentation unit 8, and an access prohibition keyword setting unit 9 are included.
The storage unit 2 stores a plurality of databases such as mail transmission / reception data 2-1, data folder 2-2, address book 2-3, schedule 2-4, bookmark data 2-5, and the like.
A plurality of data files are stored in each of the plurality of databases 2-1 to 2-5.
Although shown in FIG. 7, it is apparent that there is a configuration for performing a normal function as another information processing apparatus (for example, a portable terminal) having the functions according to the present invention.

 Next, referring to FIGS. 1 to 6, a case where the information processing device is a mobile terminal (a mobile phone, a PHS, or the like, which has a standby (standby) time for communication with a base station every predetermined time). As an example, a keyword search is executed for each data file of data files such as “mail transmission / reception data”, “data folder”, “address book”, “schedule”, “bookmark data” stored in the storage unit of the portable terminal. An example will be described.

In order to execute a keyword search on the mobile terminal, it is necessary that the keyword to be searched in advance is registered in the keyword registration unit of the storage unit of the mobile terminal (an example of a keyword list is shown in FIG. 1). .
As for keyword registration, the user individually inputs and registers “person name” as a keyword by FEP, or is included in the attribute of the address book, the group field, etc. already stored in the storage unit of the mobile terminal. Keywords can be automatically extracted and registered from each column such as “name”, “kana”, “nickname”, “birthday”, “mail address”, and “phone number”.

A procedure for setting (registering) a keyword used by a user for a search will be described with reference to FIG.
-The user performs a keyword search for each data file of the data file such as “mail transmission / reception data”, “data folder”, “address book”, “schedule”, “bookmark data” stored in the storage unit of the mobile terminal. Enter the keyword you want to search for. (Step S1)
-The processing unit (CPU) of the mobile terminal determines whether or not the input keyword has already been registered in the keyword registration unit, and if it is determined that it has not been registered, the input keyword is the keyword. Register in the keyword registration section as a list. (Step S2)

Next, using the flowchart of FIG. 3, automatically from each column of “name”, “kana”, “nickname”, “birthday”, “email address”, “phone number”, etc. included in the attribute and group fields of the address book. An example of extracting and registering keywords will be described.
A search is made for an address book stored in the storage unit of the portable terminal to extract a keyword, and a determination is made as to whether or not to execute processing for registration (setting) in the keyword storage unit. (Step S11)
Note that the user selects in advance whether or not to cut out this keyword.
In addition, the data file that is the target of the keyword extraction is not limited to the above address book, but “mail transmission / reception data” “data folder” “address book” “schedule” “stored” in the storage unit of the mobile terminal. It can be applied to any data file such as “bookmark data”.
・ If the determination in step S11 is YES,
The user selects the range of data in the address book where keyword extraction is executed, and selects from “Select all”, “Group selection”, and “Individual selection”. (Step S12)
-Select from the group, attribute, etc. to which the address book belongs, such as "name", "kana", "nickname", "birthday", "email address", "phone number", etc., as the range of keywords to be extracted from the address book . (Step S13)
The keyword having the attribute selected in step S13 is extracted from the data in the selected range in the selected data file (in this case, the address book), and a keyword candidate list is created and displayed. (Step S14)
-The user selects whether or not to register (save) as a keyword from the displayed keyword candidate list. (Step S15)
When the user selects to register (save) in step S15, the selected keyword is registered (saved) in the keyword registration unit as the keyword list of FIG. (Step S16)

  In the above description, “person name” is used as an example of keyword registration, but the registered keyword is not necessarily “person name”, and any “term” other than the person name may be used.

Next, a procedure for creating a search result table by executing a keyword search on the mobile terminal will be described with reference to the flowchart of FIG.
The keyword search is started during the standby (standby) time of the portable terminal or in response to an instruction to start keyword search by the user. (Step S21)
In the keyword search of the present invention, except for a search start instruction by a user, which is a special case, the keyword search for the data file in the mobile terminal is executed while waiting for the mobile terminal (standby).
-It is judged whether the keyword is registered into the keyword registration part of the memory | storage part of the said portable terminal. Also, it is determined whether or not the “keyword search function” is enabled on the mobile terminal. (Step S22)
If both the determinations in step S22 are YES, all the registered keywords are sequentially searched until the standby (standby) is completed or the keyword search is completed or interrupted. . (Step S23)
Data files and keywords included in the “mail transmission / reception data”, “data folder”, “address book”, “schedule”, “bookmark data”, etc. classified for each keyword based on the search result of the step S23 The corresponding search result table is created (updated). (Step S24)
The above steps S23 and S24 are repeated until the standby (waiting) is ended, or the keyword search is completed or interrupted. (Step S25)

Since the capacity (user area) of the storage unit is not large in mobile terminals, etc., a certain amount of data files are stored (saved), and the remaining amount of user area for storing (storing) new data files remains constant. When it falls below, it becomes necessary to delete a part of the stored (saved) data file.
When deleting this data file, a data file including a keyword that is used infrequently is displayed as a candidate data file to be deleted, and the deletion of the data file instructed by the user is executed.
Next, deletion of a data file stored in the storage unit of the mobile terminal will be described with reference to a flowchart in FIG.

This process is started when a data file such as standby (standby) is added.
-It is determined whether or not “deletion of data file including a keyword that is not frequently used” is set for the mobile terminal and is valid. (Step S31)
If the determination in step S31 is YES, it is determined whether or not the remaining amount of the user area for storing a new data file is below a certain value. (Step S32)
・ If the determination in step S32 is YES,
The search result table is accessed, and a data file including a less frequently used keyword is presented to the user as a deletion target candidate data file. (Step S33)
The data file to be deleted by the user is selected from the deletion target candidate data files presented in step S33. (Step S34)
-Delete the data file selected in step S34. (Step S35)
As described above, when the remaining amount of the user area for storing a new data file such as a portable terminal falls below a certain value, a data file including a keyword that is not frequently used is presented to the user as a candidate for deletion. Since the data file is deleted by the user's selection, the user area can be used effectively.

Next, data files such as “mail transmission / reception data”, “data folder”, “address book”, “schedule”, and “bookmark data” can be manipulated by others when the portable terminal is left on the desk or the like. In order to prevent access to the stored data file, a process for prohibiting access by the user is required for each data file.
Hereinafter, it is possible to access another person within the data file such as “mail transmission / reception data”, “data folder”, “address book”, “schedule”, “bookmark data” stored in the portable terminal with a simple operation using FIG. A procedure for preventing this will be described.

・ When a data file stored (saved) in the mobile terminal is accessed by an operation on the mobile terminal, whether or not a data file that the mobile terminal does not want to allow others to access is set (registered) by the user Make a judgment. (Step S41)
・ If the determination in step S41 is YES,
It is determined whether or not the accessed data file includes an access prohibition keyword set by the user. (Step S42)
-If the determination in step S41 is NO (if the user has not set access prohibition), or if the determination in step S42 is NO (if the accessed data file does not contain an access prohibition keyword), the data file Allow access to. (Step S43)

  As described above, the access prohibition data such as a specific person name is set by the user in advance, so that the access prohibition data can be configured with a simple configuration without performing special processing for prohibiting the browsing of each data file. Access to the file can be prohibited.
