The mobile phone 1 includes an operation unit 11, a display unit 21, a control unit 30, a communication unit 40, a voice control unit 50, and a storage unit 60.

  The control unit 30 controls the entire mobile phone 1, and performs predetermined control on the display unit 21, the communication unit 40, the voice control unit 50, and the like, for example. In addition, the control unit 30 receives input from the operation unit 11, the communication unit 40, and the like, and executes various processes. And the control part 30 controls the memory | storage part 60 in the case of a process execution, reads various programs and data, and writes data.

  Moreover, in this embodiment, the control part 30 performs the camouflage process mentioned later with respect to the character string input by the operation part 11, or the character string read from the memory | storage part 60, and displays the display data after a process. It is displayed on the display unit 21. Note that the functions of each unit provided for the control unit 30 to execute processing will be described later.

  The communication unit 40 communicates with an external device (for example, a base station) in a predetermined frequency band (for example, 2 GHz band, 800 MHz band, etc.). Then, the communication unit 40 demodulates the signal received from the antenna, supplies the processed signal to the control unit 30, modulates the signal supplied from the control unit 30, and transmits the signal from the antenna to the external device. To do.

  The sound control unit 50 performs predetermined sound processing on the signal supplied from the communication unit 40 under the control of the control unit 30, and outputs the processed signal to the receiver 22. The receiver 22 outputs the signal supplied from the audio control unit 50 to the outside. This signal may be output from a speaker (not shown) instead of the receiver 22 or together with the receiver 22.

  In addition, the voice control unit 50 processes the signal input from the microphone 12 according to the control of the control unit 30, and outputs the processed signal to the communication unit 40. The communication unit 40 performs predetermined processing on the signal supplied from the audio control unit 50 and outputs the processed signal from the antenna.

  The storage unit 60 includes, for example, a working memory and is used for arithmetic processing by the control unit 30. In the present embodiment, a program for executing processing described later, various application data (application DB 61), specific character string data (personal information DB 62) indicating personal information, and the like are stored. Note that the storage unit 60 may also serve as a removable external memory.

Next, each part of the control unit 30 will be described in detail.
The control unit 30 includes an input unit 31, a determination unit 32, a mode setting unit 33, a rule setting unit 34, a conversion unit 35, and an extraction unit 36.

  The input unit 31 receives input of character string data from the operation unit 11, requests display of the character string data on the display unit 21, and transmits the original character string data before being converted by the conversion unit 35 to the application DB 61. To remember.

  The determination unit 32 determines whether or not the character string data requested to be displayed on the display unit 21 includes specific character string data indicating personal information stored in the personal information DB 62.

  Based on the instruction input received from the operation unit 11, the mode setting unit 33 sets a conversion mode for converting specific character string data into special display data described later, or a conversion cancellation mode for canceling this conversion.

  The rule setting unit 34 sets which one of the plurality of conversion rules for converting the specific character string data into the special display data is used according to the type of the specific character string data. Here, the type of specific character string data refers to the type of personal information such as a person's name, address, occupation, and the like. Further, the rule setting unit 34 previously determines one conversion rule for each type of personal information based on the instruction input received from the operation unit 11.

  When the determination unit 32 determines that the specific character string data is included in the character string data requested to be displayed on the display unit 21, the conversion unit 35 sets the specific character string data as a rule setting. The data is converted into special display data according to a predetermined conversion rule set by the unit 34.

  Here, it is desirable that the special display data according to the conversion rule is easily understood by the user who is the owner of the mobile phone 1 and difficult for the third party. For example, the special display data includes the following.

(1) Display data obtained by vertically inverting the image of each character.
(2) Display data obtained by horizontally inverting the image of each character.
(3) Display data obtained by rotating the image of each character.
(4) Display data obtained by replacing characters in a character string in reverse order.
(5) Display data in which a character string is expressed as a phonetic expression. For example, “good morning” is written in Roman letters as “OHAYOU”.
(6) Display data obtained by converting a character string into another language. For example, “good morning” in Japanese is written as “GOOD MORNING” in English.
(7) Display data in which the display color of the character string is similar to or lighter than the background color. For example, as shown in Japanese Patent Application Laid-Open No. 2005-208921, gray display is used.
(8) Image data (icon) corresponding to the meaning of a character string and stored in association with the character string.
(9) Image data corresponding to each character on a one-to-one basis. For example, numbers are used as image data for dice eyes or mahjong pie.

  The conversion unit 35 converts the specific character string data when the conversion mode is set, and does not convert the specific character string data when the conversion cancellation mode is set. Further, when the conversion cancel mode is set while the special display data is displayed, the conversion unit 35 returns the converted special display data to the specific character string data before conversion and displays the converted special display data.

  The extraction unit 36 extracts specific character string data indicating personal information from the application DB 61 managed by a predetermined application, and stores it in the personal information DB 62. Specifically, the extraction unit 36, for example, from the address book data, the name, phone number, address, e-mail address, birthday, etc. from the schedule book data, the name, location, anniversary, etc. from the e-mail data URL data etc. are extracted from bookmark data, e-mail address, subject, etc. When the electronic money function is implemented, the extraction unit 36 can extract information such as a login ID, a password, and an electronic money balance from the electronic money application. Furthermore, when the pedometer function is implemented, the extraction unit 36 can extract information such as the user's body data and calorie calculation data from the pedometer application. In addition, specific character string data may be extracted from document data such as mail and memos by a technique such as morphological analysis.

FIG. 3 is a diagram illustrating a screen display example by the camouflage process according to the present embodiment.
FIG. 3A shows an e-mail editing screen when the conversion cancellation mode is set (when the camouflage function is off).

  In this example, in response to a character input (“shi”) from the operation unit 11, a candidate list 71 for receiving a selection is displayed by indicating a predicted character string (for example, phrase prediction) following this character. The candidate list 71 displays specific character string data indicating personal information such as address, hobby, occupation, and person name. Therefore, a third party can easily visually recognize such personal information.

  FIG. 3B shows an email editing screen when the conversion mode is set (when the camouflage function is on).

  In this example, the candidate list 72 is displayed in response to a character input (“shi”) from the operation unit 11 as in the case of the conversion cancellation mode (FIG. 3A). Although the candidate list 72 includes personal information, the specific character string data is converted into special display data, which makes it difficult for a third party to see. For example, character color and font change (first line), character replacement (second line), character string iconization (third line), and change to Roman characters (fifth line).

  When the conversion mode is set in the state of FIG. 3A, the state of FIG. 3B is obtained, and when the conversion cancellation mode is set in the state of FIG. 3B, the state of FIG. Become.

  In this screen display example (FIG. 3B), not only the specific character string data (“Shibuya Ward”, “Fishing”, “Shimizu”) but also a character string including the preceding and following character strings (“Address: Shibuya”). Ward "," hobby fishing "," Mr. Shimizu ") has been converted to special display data. That is, the conversion unit 35 may convert the entire character string having a dependency relationship with the word indicating personal information. This further suppresses leakage of personal information.

FIG. 4 is a flowchart showing a flow of camouflage processing according to the present embodiment.
In step S1, the control unit 30 determines whether or not a character string display request has occurred. If this determination is YES, control unit 30 moves the process to step S2. If the determination is NO, control unit 30 continues step S1 and waits for a display request.

  In step S2, the control unit 30 determines whether or not the camouflage function is on, that is, whether or not the conversion mode is set (conversion release mode). If this determination is YES, control unit 30 moves the process to step S3, and if the determination is NO, the control unit 30 moves the process to step S6.

  In step S3, the control unit 30 (determination unit 32) determines whether or not the character string requested to be displayed in step S1 includes specific character string data indicating personal information. When this determination is YES, control unit 30 moves the process to step S4, and when the determination is NO, the control unit 30 moves the process to step S6.

  In step S4, the control unit 30 (conversion unit 35) determines a conversion rule for converting the specific character string data determined in step S3 into a camouflage type, that is, special display data.

  In step S5, the control unit 30 (conversion unit 35) converts the specific character string data into special display data according to the conversion rule determined in step S4.

  In step S <b> 6, the control unit 30 causes the display unit 21 to display the character string in which the specific character string data is camouflaged in step S <b> 5 or the character string that does not require camouflage.

  Thus, although the displayed character string is camouflaged by the camouflage process, the original character string from which the camouflage has been canceled is stored in the storage unit 60. When the stored character string is read and displayed again, if the camouflage function is on (conversion mode), the displayed character string is camouflaged.

  That is, the mobile phone 1 can make the displayed data different from the stored data. For example, when sending an e-mail, camouflaged data is displayed on the editing screen, but the original character string before camouflaging is also stored. Therefore, the mail data actually transmitted via the communication unit 40 is the original correct character string. Note that the user can confirm the character string that is actually transmitted by temporarily turning off the camouflage function (conversion release mode) on the editing screen.

  As described above, according to the present embodiment, the mobile phone 1 converts the specific character string data indicating personal information into special display data whose meaning is difficult for a third party to understand, and displays the converted data. Therefore, the mobile phone 1 can make it difficult for a third party to visually recognize a specific character string without deteriorating user convenience.

  At this time, the mobile phone 1 displays the specific character string data of the input character string by camouflaging and stores the character string data before conversion. Accordingly, the mobile phone 1 can store only the input correct character string, but can convert only the display data (camouflage) as necessary to make it difficult to be viewed by a third party.

  In addition, the mobile phone 1 can switch between a conversion mode in which the specific character string data is camouflaged and a conversion cancellation mode in which the camouflaged special display data is returned to the original specific character string data. Therefore, since the mobile phone 1 can camouflage the character string only when the user needs it, convenience for the user is improved.

  Further, the mobile phone 1 can use a plurality of camouflage conversion rules. For example, one can be selected according to the type of specific character string data. Therefore, the mobile phone 1 can camouflage the specific character string data using a plurality of types of special display data, and can make it difficult for a third party to visually recognize the character string data.

  Furthermore, the mobile phone 1 can set a camouflage conversion rule according to the type of the specific character string data, for example, based on an instruction input from the user. Therefore, the mobile phone 1 can improve visibility and convenience for the user.

  Further, since the mobile phone 1 extracts specific character string data from the database managed by the application, the specific character string data such as the latest personal information can be acquired from the application data that changes every moment. Therefore, the mobile phone 1 can further suppress leakage of the specific character string data.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.

  In the above-described embodiment, the specific character string data has been described as a character string indicating personal information. However, the present invention is not limited to this and can be applied to other confidential information.

  In the above-described embodiment, only the character string data displayed on the display unit 21 is converted, and the character string data before conversion is stored in the storage unit 60. However, the present invention is not limited to this. That is, the converted data may be stored in the storage unit 60. In this case, the stored data after conversion is restored to the original character string data by setting the conversion cancellation mode.

  In the above-described embodiment, the mobile phone 1 is described as an electronic device. However, the electronic device is not limited to this, and the present invention is not limited to the PHS (registered trademark; Personal Handyphone System) and PDA (Personal Digital Assistant). ), A game machine, a navigation device, a personal computer, and the like.
