  According to the present invention, it is possible to provide an information processing apparatus, an information leakage prevention method, and a program that can prevent information leakage.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of a portable information processing apparatus according to the present invention. FIG. 2 is a functional block diagram of the portable information processing apparatus.
As shown in FIGS. 1 and 2, the PDA 10 includes an operation unit 20, a touch pen 30, a display unit 40, an earphone 50, a control unit 60, and the like.
The operation unit 20 is used by the user to give various instructions to the PDA 10.
The touch pen 30 touches the touch panel 42 of the display unit 40 and inputs position information on the touch panel 42 to the control unit 60. The user can also give various instructions to the PDA 10 with the touch pen 30.

The display unit 40 includes a display 41 and a touch panel 42, and a transparent touch panel 42 is stacked on the display 41.
The earphone 50 functions as a sound output unit, and outputs sound to the user when the user who uses the PDA 10 wears it. The earphone 50 is detachably attached to the PDA 10.

  The control unit 60 controls the operation of the entire PDA 10, and includes a display control unit 61, a reception unit 62, an audio output control unit 63, an authentication unit 64, and the like. As shown in FIG. 3, the control unit 60 includes a ROM (Read Only Memory) 67a, a CPU (Central Processing Unit) 67b, a RAM (Random Access Memory) 67c, an interface 67d, and the like. FIG. 3 is a diagram illustrating a hardware configuration of the control unit 60.

  The display control unit 61 outputs image information to the display 41 to display a predetermined image. Further, the character information stored in the storage unit 70 is converted into a predetermined symbol and displayed on the display 41 in a state where the character information is concealed.

  The accepting unit 62 accepts an operation instruction for the PDA 10 based on a signal input from the touch panel 42 or the operation unit 20. In addition, as will be described in detail later, the receiving unit 62 receives designation of a target to be output from the hidden character information. The accepting unit 62 accepts designation of a target to be hidden and displayed.

  The audio output control unit 63 outputs audio to the earphone 50 that is externally connected to the PDA 10. In addition, the voice output control unit 63 outputs the original character information corresponding to the character information concealed and displayed on the display unit 40 to the earphone 50 as a voice. Specifically, the voice output control unit 63 acquires the original character information of the hidden and displayed character information from the display control unit 61. By acquiring this original character information, the audio output control unit 63 can output audio to the earphone 50.

  Although the authentication unit 64 will be described in detail later, when restoring the hidden character information to the original character information, the authentication unit 64 designates the user who has designated the character information to be hidden and the target to be hidden. Authenticate with the user who cancels the specified character information.

  The storage unit 70 includes an HDD and stores character information as a text file or the like.

Next, processing of the control unit 60 will be described.
FIG. 4 is a flowchart illustrating an example of character information conversion processing executed by the control unit 60. This process is a process for converting character information into a predetermined symbol for each character included in the character information in order to conceal the character information. FIG. 5 is a schematic diagram showing an example of conversion of character information.

  The accepting unit 62 determines whether or not the instruction from the user is to convert the full text of the character information into a symbol (step S1). When the entire text of character information is converted, the character information before conversion shown in FIG. 5A is converted into a symbol of ● for each character as shown in FIG. 5B (step S4). ). Thus, the character information is converted into a symbol having no meaning. Therefore, when the converted character information is displayed on the display 41, even if it is read by a third party, information leakage is prevented. Can be prevented.

  In step S1, when not converting the whole sentence into symbols, the receiving unit 62 determines whether or not the instruction from the user is to convert only a preset keyword part (step S2). If only the keyword part is to be converted, only the corresponding keyword part in the character information is converted to ● (step S4). As a result, the user can convert only important parts into symbols, and since characters are displayed in the normal state in other parts, it is easy to grasp the contents of the character information.

  If it is determined in step S2 that only the keyword portion is not converted, the receiving unit 62 determines whether a predetermined character has been touched by a signal from the touch panel 42 (step S3). When a predetermined character is touched, for example, as shown in FIG. 5C, only the touched character is converted into ● (step S4). The user can perform this conversion by using the touch pen 30.

  In this way, the user can designate the target to be concealed, so that only the character information that is not desired to be read by another person can be designated and concealed. Thereby, the designated character information is displayed in a hidden manner, but other character information is displayed in a normal state, so that it is easy to grasp the entire character information.

  Next, it is determined whether or not there is an instruction to confirm with the converted contents (step S5). If not determined, the control unit 60 executes the process from step S1 again. When there is an instruction to confirm, the display control unit 61 causes the display unit 40 to display a password input screen. FIG. 6 is an exemplary view of a password input screen displayed on the display unit 40. When the user inputs the password, the control unit 60 causes the storage unit 70 to store the contents of the converted character information. The original character information of the converted character information is not displayed on the display unit 40 or the like, but is stored in the storage unit 70 in association with the converted character information.

  If it is determined in step S3 that the predetermined character has not been touched, and if the converted content is not confirmed in step S5, the receiving unit 62 executes the process of step S1 again.

Next, the audio output process executed by the control unit 60 will be described.
FIG. 7 is a flowchart illustrating an example of an audio output process executed by the control unit 60.
The voice output process is a process for outputting the hidden character information as a voice. FIG. 8 is an exemplary diagram of character information hidden and displayed on the display unit during voice output.
The accepting unit 62 determines whether or not the instruction from the user is to automatically read out the entire sentence (step S11). In the case of automatic reading, the voice output control unit 63 recognizes a character included in the original character information before conversion, which is attached to the converted character information, and outputs the whole sentence to the earphone 50 (step S14). ). As a result, the user can hear the contents of the character information while viewing the converted character information, that is, the character information concealed and displayed on the display unit 40.

  Next, the display control unit 61 causes the display unit 40 to display the character information that has already been output as speech so that the character information that has not been output as speech can be identified. Specifically, ● corresponding to the character already output by voice is converted into ○ and displayed (step S15). FIG. 8A is an exemplary view at that time. Corresponding to the character read out, it is converted from ● to ○ and displayed.

  If there is no automatic reading instruction, the accepting unit 62 determines whether or not ● has been touched (step S12). If touched, the audio output control unit 63 outputs only the touched ● to the earphone 50 (step S13). After step S13, as in the case described above, the display control unit 61 converts ● that corresponds to the already output character to ○ and displays it (step S15). FIG. 8B is an exemplary diagram when the user uses the touch pen 30 to touch the ● to output sound.

  Thus, since the character information is concealed and displayed on the display unit 40, it is possible to prevent information from leaking when a third party steals the display unit 40. Further, since the hidden character information is output as voice through the earphone 50, the contents of the hidden character information can be heard. This prevents leakage of character information and allows the user to grasp the content of the character information.

  In addition, the display control unit 61 displays the character information that has already been output from the character information that has been concealed so as to be distinguishable from the character information that has not been output (step S15). Therefore, the user can grasp the character information that is output as voice and the character information that is not displayed among the character information displayed in a concealed manner. Therefore, the user can grasp to which position the voice information is output in the hidden character information.

  The accepting unit 62 accepts designation of a target for audio output (step S12). Therefore, for example, the user can designate and output sound for each easy-to-hear amount.

  Next, the reception unit 62 determines whether or not there is an instruction for reading again (step S16). If there is no instruction for reading again, this process is terminated. If there is an instruction for reading again, the receiving unit 62 determines whether the instruction is for automatic reading (step S17). In the case of an automatic reading instruction, the display control unit 61 converts the ○ corresponding to the character that has already been voice output to ● and displays it (step S20), and the voice output control unit 63 again returns to step S14. Execute the process.

  When there is no instruction for automatic reading, the receiving unit 62 determines whether or not “◯” has been touched (step S18). If the circle is not touched, the accepting unit 62 executes the process of step S16 again. If it is touched, the display control unit 61 converts the touched mark into ● (step S19). After the conversion, the accepting unit 62 executes the process of step S11 again.

  In this way, the accepting unit 62 accepts selection of character information to be output again from the character information that has been concealed and has already been output. Thereby, the user can repeatedly listen to the content of the character information and can fully grasp the content.

Next, the restoration process executed by the control unit 60 will be described.
FIG. 9 is a flowchart illustrating an example of a restoration process executed by the control unit 60.
This restoration process is a process for restoring the character information after the symbol conversion to the original character information before the conversion.

  If there is an instruction for the restoration process, the display control unit 61 causes the display unit 40 to display the screen of the password input illustrated in FIG. 6 (step S31). Next, the receiving unit 62 determines whether or not the input password matches the password input in step S6 described above (step S32). When the passwords match, the display control unit 61 restores the character information on the assumption that the user who converted the character information into a symbol matches the user who cancels the conversion and restores the original character information. To display.

With such a configuration, only the user who conceals the character information can restore the original character information. Thereby, restoration of character information by a third party can be prevented, and information leakage can be prevented.
If the passwords do not match, the control unit 60 ends this process without performing the character information restoration process.
