Description

  The present invention relates to a portable terminal device, a character string input method, a character string input program, and a recording medium, and more particularly, to a portable terminal device that stores a character string with a title added thereto, a character string input method, a character string input program, and a recording medium. About.

  A portable terminal device that has recently become widespread has a fixed sentence input function for easily inputting a character string registered in advance when inputting characters (see, for example, Patent Documents 1 and 2). In addition, the mobile terminal device can connect to a network by wireless communication and receive various services on the Internet. For example, you can check your bank account balance or make a transfer. Here, in order to receive various services, it is often necessary to input a password on the browser. Although the input character is a hidden character, it is very difficult to input a password with a mixture of alphanumeric characters with a numeric key input device installed in a portable terminal device. In addition, if the user makes a mistake in entering the password a predetermined number of times per day, such a service is not available on that day, and the burden caused by a mistake in entering the password is large.

  As a workaround, there is a means to simplify the input by using only a password as a password, but a password with only a numeric value causes a decrease in security. In addition, there are passwords that cannot be changed by the initial value or cannot be defined only by numerical values, and in that case, it becomes difficult to input the password on the mobile terminal device.

Therefore, it is conceivable to use the fixed sentence input function of the portable terminal device. By registering a password in advance as a fixed phrase, it is possible to input an accurate password only by selecting a predetermined fixed sentence from the fixed phrases on the password input screen. However, when calling a fixed phrase, the password is displayed as it is. A similar problem occurred when a character string other than a password that was not wanted to be seen by other people was registered in the mobile phone and used for character input. Therefore, a secret memory device has been proposed in which the memo contents are called and displayed only by the password (see, for example, Patent Document 3).

  However, the above techniques have the following problems. There is a security problem that when a password is registered in advance in the fixed text function installed in the mobile phone, the password is displayed as it is when the standard text function is opened next time, so that it can be seen by others. A similar problem occurred when a character string other than the password was registered in the mobile phone and it was desired to use it separately when entering characters. In addition, since the key input unit mounted on the portable terminal device is small, it is difficult to operate, and it is very difficult to input a character string mixed with alphanumeric characters.

  The present invention has been made in view of such a situation, and when inputting a pre-registered character string, it is necessary to input a personal identification number for the specific character string, and a title is added to the character string. When selecting a character string, the object is to further improve security by displaying a title instead of a character string.

  A first portable terminal device according to the present invention includes a recording unit that records at least one or more character strings, a list display unit that displays a list of the recorded character strings, and a character string input unit that inputs a selected character string. And title adding means for adding a title to the character string, wherein the list display means displays the title when the title is added, and the list display means includes a specific character string or When a title corresponding to a specific character string is displayed, it is displayed only when a predetermined password is input, and the character string input means inputs a character string corresponding to the selected title. And

  The first character string input method of the present invention includes a step of recording at least one character string, a step of displaying a list of the recorded character strings, a step of inputting a selected character string, and the character string Adding a title to the list, wherein the step of displaying the list displays the title when the title is added, and the step of displaying the list includes a specific character string or a specific character string. The corresponding title is displayed only when a predetermined password is inputted, and the step of inputting the character string inputs a character string corresponding to the selected title.

  The first character string input program of the present invention includes a recording process for recording at least one character string, a list display process for displaying a list of the recorded character strings, and a character string input for inputting a selected character string. Processing and a title addition process for adding a title to the character string. The list display process displays the title when the title is added, and the list display process When a title corresponding to a specific character string or a title corresponding to a specific character string is displayed, it is displayed only when a predetermined password is input, and the character string input process inputs a character string corresponding to the selected title. It is characterized by doing.

  A first recording medium of the present invention is a computer-readable recording medium that records the processing of the first character string input program of the present invention.

  According to the present invention, when inputting a pre-registered character string, it is necessary to input a personal identification number for the specific character string, and adding a title to the character string and selecting the character string By displaying the title instead of, security can be further improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, since the Example described below is a suitable Example of this invention, various technically preferable restrictions are attached | subjected, However, The scope of the present invention limits this invention especially in the following description. As long as there is no description of the effect, it is not restricted to these aspects. In this specification, the character string (also referred to as a fixed phrase) is not particularly limited with respect to the number of characters and the type of characters, and is a type of character including all alphanumeric characters, kana / kanji, and symbols, and includes one or more characters. Composed.

  FIG. 1 is a block diagram of a mobile phone 101 as an example of a mobile terminal device according to an embodiment of the present invention. A CPU 102, a fixed phrase recording memory 103, a transmission / reception unit 104, a ROM 105, a work memory, a key input unit 107, operation keys 108, a display control unit 109, and a display unit 110 are configured.

  A CPU (central processing unit) 102 is connected to each unit in the apparatus. Of these, the ROM 105 is a read-only memory that stores various control programs to be executed by the CPU 102 and fixed data such as a dictionary used for kana character conversion.

  The work memory 106 is constituted by a RAM (Random Access Memory), and stores data temporarily required for the CPU 102 to execute the program.

  The fixed sentence recording memory 103 is a memory for storing a fixed sentence folder name, a fixed sentence character string, and a fixed sentence title, and is composed of a nonvolatile memory.

  The key input unit 107 is an input circuit that receives key inputs from the operation keys 108. The operation keys 108 include a numeric keypad, a start key, an end key cursor key, and the like. Input of alphabets and Japanese is realized by pressing a numeric keypad a plurality of times and selecting a predetermined character.

  The display control unit 109 is a control circuit that controls display on the display unit 110. The display unit 110 is disposed on the front surface of a device main body (not shown), and is a display device such as a monochrome or color liquid crystal panel or organic EL (electrofluorescence).

  The transmission / reception unit 104 is a circuit that performs transmission / reception of data such as voice calls and mails wirelessly.

  FIG. 2 is a diagram illustrating an example of a fixed phrase format. There are two types of fixed phrases: normal fixed phrases (normal folders 1 to 5) and fixed phrases with security (security folders) (201).

  The normal fixed sentence is composed of a folder name character string and fixed form sentence data (202), and the normal fixed form sentence data 204 stores the fixed form sentence character string.

  The fixed sentence with security 205 stores a fixed sentence title and a fixed sentence character string.

  The initial value of the fixed phrase data may be blank, or the initial value may be defined in advance. Also, the number of folders that can be registered and the number of fixed phrases are arbitrary. In the normal fixed sentence data 204 and the fixed sentence data with security 205, n indicates the maximum number that can be registered.

  Although the configuration of the present embodiment has been described in detail above, the mechanism of the transmission / reception unit 104 in FIG. 1 is well known to those skilled in the art and is not directly related to the present invention, so the detailed configuration is omitted.

  Next, the operation processing of the present embodiment will be described with reference to the flowchart of FIG. FIG. 3 is a flowchart illustrating the fixed sentence registration operation process according to the present embodiment.

  First, when a fixed phrase is selected from the setting menu of the mobile phone, a fixed phrase folder selection screen is displayed (S301). A normal folder and a security folder are displayed on the selection screen.

  Next, a folder to be registered is selected by the key operation 108 (S302). If the selected folder is a security folder, the personal identification number is input on the personal identification number input screen (S303).

  It is determined whether or not the authentication is OK (S304). If the authentication is NG, the password input can be retried on the password input screen again (S303).

  If the authentication is OK, the standard text title list is displayed on the standard text editing screen and an item is selected (S305). At this time, it is also possible to end without selecting (S306 / Yes).

  When an item to be registered is selected, a fixed phrase and a fixed phrase title are input and registered (S307, S308). After that, the fixed phrase and the fixed phrase title can be registered until the selection is completed (S306 / Yes).

  On the other hand, when the normal folder is selected (S302 / normal folder), the standard text item is selected on the standard text editing screen (S309), and the standard text is registered (S311). Also in this case, the fixed sentence can be registered until the selection is completed (S310 / Yes).

  Note that if a fixed phrase item already registered in S306 is selected, a character string registered in the past is displayed on the fixed phrase or fixed phrase title registration screen, and correction can be made.

  FIG. 4 is a diagram for explaining an example of a screen image corresponding to the operation process (FIG. 3). When the security folder (6) is selected on the fixed phrase folder selection screen 401, a personal identification number input screen 402 is displayed. When a personal identification number is entered and authenticated, a security folder template edit screen 403 is displayed. When an item is selected, a fixed sentence and a title can be input from the fixed sentence edit screen 404 and the title input screen 405, respectively. When the confirm button is selected, the registration is completed as shown in the security folder template editing screen 406. On the other hand, when the normal folders (1) to (5) are selected, the normal folder fixed sentence editing screen 407 is displayed, and the fixed sentence can be registered from the fixed sentence editing screen 408.

  Next, an operation process when using a fixed phrase registered in advance by the above process will be described. FIG. 5 is a flowchart showing a character input operation process using the fixed sentence function.

  First, a function is selected on the character input screen (S501) (S502). In function selection, a fixed sentence function, end, and other (other than fixed sentence function and end) functions can be selected.

  When the fixed phrase function is selected, a fixed phrase screen is displayed, and a folder in which the target fixed phrase is stored can be selected (S503).

  If the selected folder is a security folder (S504 / security folder), a password is input (S505). If the authentication is OK (S506 / Yes), a list of fixed phrase titles is displayed (S507). A target title is selected from the list of fixed phrase titles (S507). The fixed phrase of the selected title is pasted on the character string input screen (S508).

  On the other hand, when the type of the selected folder is a normal folder (S504 / normal folder), a list of fixed phrases is displayed (S509). When the target fixed phrase is selected, the selected fixed phrase is pasted on the character string input screen (S510).

  FIG. 6 is a diagram for explaining an example of a screen image corresponding to the operation process (FIG. 5). For example, when a password field is selected on the login screen 601, a password input screen 602 is displayed. Here, in order to use the fixed sentence function, first, a function menu is called (screen 603). When the fixed phrase function (7) is selected from the function menu, a fixed phrase folder selection screen 604 is displayed. When the security folder (6) is selected, a password input screen 605 is displayed. When the personal identification number is entered and authenticated, the security fixed phrase list screen 606 in the security folder is displayed. Since the security fixed phrase list is a list of titles (for example, “Himawari Bank” see FIG. 6), there is no risk of others seeing the screen. When a desired title is selected from the list, a fixed phrase (character string) of the selected list is input to the password input screen 607. On the other hand, when the normal folders (1) to (5) are selected, the standard text list screen 608 in the normal folder is displayed, and the standard text to be input can be selected from here.

  According to the above embodiment, when using a fixed phrase input function for easily inputting a pre-registered character string, a password for confirming the use of a specific fixed sentence is input, and a character string title is added to the registered character string. Is added, and a title is displayed instead of a character string, so that the fixed sentence character string can be expressed by an alias, and the fixed sentence can be selected and used easily and visually. For example, when a plurality of bank IDs, which are random character strings, are registered, by registering the character string titles with the titles of XX bank and △ Δ bank, they can be visually selected when actually used. Therefore, according to the present invention, various passwords and secret information character strings can be safely registered in the portable terminal device. For example, it becomes possible to input IDs and passwords easily and safely on a browser screen or the like.

  Next, another embodiment of the present invention will be described.

  The personal identification number that is input and authenticated when the security folder is selected may be a common personal identification number for the mobile phone, or a personal identification number dedicated to the security folder may be separately defined.

  In addition, a password may be added to each security-added sentence (addition of an individual password). More specifically, for example, by enabling “registration of a fixed sentence unique password” after S308 in FIG. 3, the fixed sentence individual password is used for the next use, editing, or deletion. Then, security is further improved.

  Further, only when the individual password is registered, double authentication may be performed by inputting the individual password after the normal password input.

  Also, after S308 in FIG. 3, a password input-only attribute can be registered, and a security template with the attribute added can be selected only in the input part having the password attribute on the browser screen. , The standard text with security can be pasted only on the character input screen in the hidden character display, and the password is not leaked to the outside, so that stronger security can be secured. A fixed phrase without an attribute can be pasted on any character input screen.

  In the above embodiment, the normal folder and the security folder are distinguished, the normal folder stores a fixed phrase, and the security folder stores a security fixed phrase. It can be considered to change to a fixed sentence with security. Specifically, if you select a standard phrase and select Secret Settings from the function menu, a screen for entering a fixed phrase title will be displayed. After registering the desired fixed phrase title, the fixed phrase will be used instead of the fixed phrase. Make the title appear. In addition, in order to distinguish from a normal fixed sentence, it can also be considered that an icon indicating security is displayed at the head of the title or color-coded.

  When the fixed phrase input function is selected from the function menu, a list of normal folders and security folders is displayed as shown on a screen 604 in FIG. The operations up to this point can be easily performed by others, and considering the case where the security code when selecting a security folder is the initial security code of the mobile phone (there are many “0000”), the security level Depending on the function (email function, phone book function, etc.) that is activated when the standard text input function is selected, whether or not to include the security folder in the standard text folder list in advance It is possible to set it. For example, in the case of i-mode communication, after SSL authentication, etc., it may be possible to display a list of fixed sentence folders including a security folder, and to make a list of only normal folders otherwise.

  In addition, although the said Example demonstrated using the mobile telephone 101 as an example of a portable terminal device, all the apparatuses which a fixed sentence function operate | moves, such as PHS (Personal Handy phone System), are included.

  Note that the program for the CPU to execute the processing shown in the flowcharts of the drawings constitutes a program according to the present invention. As a recording medium for recording the program, a semiconductor storage unit, an optical and / or magnetic storage unit, or the like can be used. By using such a program and recording medium in a system or the like having a configuration different from those of the above-described embodiments and causing the CPU to execute the program, substantially the same effects as those of the present invention can be obtained.

  Although the present invention has been specifically described above based on the preferred embodiments, it is needless to say that the present invention is not limited to the above and can be variously modified without departing from the gist thereof.
