BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal having an information secreting function and an information secreting method thereof, and more particularly, to a portable terminal having an information secreting function using a motion recognition sensor and a method for secreting the same.

In general, mobile phones, communication terminals such as PDAs (Personal Digital Assistants), and portable terminals provide various applications such as message service, memo, schedule management, and picture storage.

Most of the terminals have a display unit for visually confirming the information such that a user can check information such as a message, a memo and a picture.

When the information of the service is displayed on the display as text or picture by executing a service such as creating, storing, or confirming a message or memo picture, the color of the text font or picture is displayed in a color distinguishable from the background screen. do. As such, the color for displaying information such as text and pictures is different from the background screen color, so that the user can check the information about the information. At this time, not only the user but also the information can be viewed through the display unit of the terminal.

Therefore, in public places where there are other people, such as subways and buses, when the user writes, receives, and checks messages, schedules, memos, pictures, and the like, the contents can be easily checked by not only users but also those around them. Therefore, there is a risk that personal information, such as phone numbers and passwords, will be exposed to others. In addition, the exposed information may be abused to cause a problem that may damage the user.

The present invention provides a portable terminal having a maintenance secret function and a method for secreting the information in order to enhance security of personal information displayed on a terminal display unit which is easily exposed to others.

According to an embodiment of the present invention, if it is determined that a shake occurs above a predetermined threshold in the mobile terminal according to a motion recognition sensor for detecting a shake occurring in the mobile terminal and a detection result by the motion recognition sensor, generating a secreting signal. According to the control unit and the secreting signal, a secreting processor for executing secreting on the display information currently displayed on the portable terminal is provided.

The display information may include at least one of text information and image information.

Here, the sparking processing unit performs the sparking by converting the color on which the display information is displayed to the same color as the screen background color according to the sparking signal.

Here, when the motion recognition sensor detects a shake above a predetermined threshold in the portable terminal in a state in which the display information is sparked, the controller generates a spark cancellation signal, and the spark processor releases sparks of the display information according to the spark clear signal.

Here, the control unit generates a deactivation signal when a preset selection signal is transmitted from the input unit of the portable terminal while the display information is deactivated, and the deactivation processor releases deactivation of the display information according to the deactivation signal.

Here, the sparking processor may convert the color on which the display information is displayed to a color different from the screen background color so that the display information in the clearing state can be checked again when the clearing signal is transmitted.

According to the portable terminal having the information secreting function and the information secreting method according to the present invention, by using the motion recognition sensor, the personal information of the user can be prevented from being exposed to others.

Therefore, it is possible to reduce the damage caused by the misuse of personal information exposed to others through the portable terminal device.

Hereinafter, an embodiment of a portable terminal having an information secreting function and an information secreting method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

Prior to the detailed description of the drawings, it is intended to clarify that the division of the components in the present specification is only divided by the main function of each component. That is, two or more components to be described below may be combined into one component, or one component may be provided divided into two or more for each function. Each of the components to be described below may additionally perform some or all of the functions of other components in addition to the main functions of the components, and some of the main functions of each of the components are different. Of course, it may be carried out exclusively by. Therefore, the presence or absence of each component described through this specification should be functionally interpreted, and for this reason, the configuration of the components of the mobile terminal with the information secreting function of the present invention can achieve the object of the present invention. Clearly, it may be different from FIG. 1 within the limits. In addition, the portable terminal having the information secreting function of the present invention may exist independently but may exist as part of a terminal on which a specific application may be executed.

1 is a block diagram showing a configuration of a portable terminal having an information sparking function according to an embodiment of the present invention.

Referring to FIG. 1, a personal information security terminal 100 including a motion sensor according to an embodiment of the present invention may include an input unit 101, a motion recognition sensor 102, a control unit 103, a secretion processing unit 104, and a display unit. It consists of 105. In FIG. 1, components of a portable terminal having an information secreting function are referred to as an input unit 101, a motion recognition sensor 102, a control unit 103, a secretion processing unit 104, a display unit 105, and the like. It will be apparent that it can be configured as a part of the components of the conventional terminal even if not explained.

In addition, although not shown in FIG. 1, the terminal 100 may include a storage unit for storing personal information and a driving application. Hereinafter, the functions and roles of the components shown in FIG. 1 will be briefly described.

The input unit 101 may be a keypad or a touch screen composed of one or more key buttons.

The motion recognition sensor 102 detects a shake occurring in the terminal 100.

In addition, the motion recognition sensor 102 may be any one of a geomagnetic field sensor, an acceleration sensor, and a combination thereof.

In addition, the motion recognition sensor 102 may be a device included in the terminal 100 as a component of the terminal 100 or connected to the terminal 100.

In addition, the motion recognition sensor may operate only in an activated state according to a user's selection using the terminal. For example, when the motion recognition sensor operates at all times, the battery consumption of the mobile terminal may increase, so that the motion recognition sensor may operate only when the motion recognition sensor is activated by pressing a specific key. . For the same purpose, the motion recognition sensor may be activated and operate only when the terminal is set to the secret mode.

The control unit 103 generates a secret signal when it is determined that the shaking of the predetermined threshold or more occurs in the terminal 100.

Here, the secret signal is generated only when the terminal 100 is in the secret mode.

In this case, when the terminal 100 receives the speech signal and the speech cancel signal, the terminal 100 may perform the secret speech and the speech cancel function.

In addition, the controller 103 generates a sparking release signal when the motion recognition sensor 102 detects a shake of a predetermined threshold or more in the terminal 100 while the display information is sparked. For example, even if a shake is detected from the motion recognition sensor, the controller 103 may not generate a talk signal or a talk cancel signal when the shake level is less than a preset threshold. This should not be recognized as a request signal for sparking or clearing when a shake occurs that does not match the user's intention (for example, a shake that can occur as the user walks with the mobile terminal). Because there is a need.

Here, the display information includes at least one of text information (for example, a text message, a personal memo, etc.) and image information (for example, a picture, a picture, a video, etc.) displayed on the screen of the terminal 100. Information.

Here, the deactivation signal is generated when the terminal 100 is in the deactivation mode.

The secretion processing unit 104 executes a secret for the display information displayed on the terminal 100 according to the secret signal.

For example, the sparking processing unit 104 may convert the color in which the display information is displayed by the sparking signal to the same color as the background color of the screen (display section 105).

In addition, the sparking processing unit 104 releases the clearing of the display information according to the clearing signal. For example, the sparking processing unit 104 may convert the color on which the display information is displayed into a color different from the background color of the screen (display section 105) so that the display information in the clearing state can be checked again.

The above-described method of processing the sparking or clearing according to the present invention through the motion recognition sensor 102, the controller 103, and the sparking processing unit 104 can be more clearly understood through the description of FIGS. 2 to 6. will be.

2 to 6 are flowcharts illustrating a secretion method using a portable terminal having an information secretion function according to various embodiments of the present disclosure. Hereinafter, an information secreting method according to embodiments of the present invention will be described for each embodiment.

2 is a flowchart illustrating an information secreting method according to an embodiment of the present invention.

Referring to FIG. 2, in order to visualize the display information, the terminal checks whether shaking is detected (S201). Here, the detection of shaking of the terminal may be performed by a motion recognition sensor (see 102 of FIG. 1) provided in the terminal.

Subsequently, if the shaking of the terminal is detected in step S201, it is checked whether the shaking occurs above the threshold set in the terminal (S202). This may be by the control unit (see 103 of FIG. 1) of the terminal.

If the shaking of the terminal is not detected in step S201, the secretion ends (S205). In addition, even if the shaking of the terminal is detected in step S201, if the shaking does not occur more than the threshold set in advance in step S202, the secretion may be terminated (S205).

Subsequently, when it is determined in step S202 that the terminal shakes more than a preset threshold, the controller 103 generates a secret signal (see step S203 in FIG. 2).

Subsequently, the display information is secreted invisible on the screen of the terminal by the secreting signal generated in step S203 (S204). Secreting through this step may be performed by the sparking processing unit 104 of FIG.

Here, the secret means to hide the display information displayed on the terminal screen by the user so as not to be exposed to others. For example, if a user checks a text message on the terminal screen and executes a secret message, the text message may be sparked by converting the text message font color and the background color of the terminal screen into the same color.

As another example, a text message may be made while a predetermined background screen appears on the terminal. In addition, the text message may be distributed in an arbitrary direction on the screen of the terminal, or the text message of the text message may be changed in an arbitrary order so that the secret message may be made.

3 is a flowchart illustrating a personal information decryption method according to an embodiment of the present invention. Hereinafter, in describing the flowchart of FIG. 3, a description of parts that may be overlapped with or similarly applied to the description of the flowchart of FIG. 2 will be omitted. The same is true in the description of other embodiments of FIGS. 4 to 6 which will be described later.

Referring to FIG. 3, in order to clear the display information in the non-enhanced state, the terminal first checks whether a shake is detected (S301).

Subsequently, if the shaking of the terminal is detected in step S301, it will be checked whether the shaking above the threshold set in the terminal has occurred (S302).

If the shaking of the terminal is not detected in step S301 or if the shaking of the terminal is not detected, the shaking is terminated (S304).

Subsequently, if a shake is generated at the terminal in step S302 or higher than a preset threshold value, in step S303 a non-shutdown signal is generated.

Subsequently, the display information is de-asserted (S304) by the de-assertion signal generated in step S303.

In this case, the release of the secretion is to display the display information secreted by the user so as to be confirmed through the screen of the terminal.

For example, when the text message and the screen background color of the terminal are converted to the same color and the secretion is executed, the secret message may be released by converting the text message and the background screen color into different colors.

That is, the text message and the background screen color may be converted to any other color, but different colors. Also, the text message and the background color may be restored to the state before the secretion was executed.

As another example, if an image is executed while a random background screen set by a user is displayed on a screen of the terminal, the image may be canceled by recovering the background image by the non-encoding signal and recovering the state before the image is executed. have.

In another example, when a story is released, the story can be cleared by making the text message appear slowly, with the effect of scattering graphical elements such as pencil powder.

That is, when the user shakes the terminal to release the secret message, the text message may be displayed on the screen of the terminal while the graphic element is disturbed or blurred according to the direction and intensity of shaking the terminal.

At this time, if the user shakes the terminal faster than a certain speed or slows it below a certain speed, the graphic element may be disturbed or blurred at a corresponding speed.

In addition, if the terminal is repeatedly shaken up and down with respect to the screen of the terminal, the graphic element may be synchronized to a direction in which the terminal is shaken, and the graphic element may be disturbed or blurred from the upper and lower portions of the screen.

In addition, according to the shaking degree of the terminal, the text color and the screen background color of the text message may gradually become darkened, thereby enabling the user to check the text message.

As another example, even if a text message is distributed in a random direction on a terminal screen or a text message is changed in an arbitrary order, the text message may be recovered to a state before the text is executed even if the text message is secreted. have.

As another example, when the secretion signal and the clearing occur during the threshold time, the text color or the screen background color of the text message may be converted only during the threshold time.

Here, the threshold time may be a time for which the secretion signal and the secretion signal are continuously generated.

For example, the secretion may be executed while the secretion release signal is generated to gradually increase the font color of the text message.

At this time, if the screen background color is white and the deactivation signal is generated for 5 seconds, the text color of the text message may be gradually darkened only for 5 seconds when the deactivation signal is generated. At this time, the text message may be completely displayed on the screen of the terminal for 5 seconds, which is the threshold time, and the secret message may not be completely cleared.

4 is a flowchart illustrating a personal information secreting method according to another embodiment of the present invention.

Referring to FIG. 4, in order to visualize the display information, the terminal may check whether a selection signal has been received (S401).

Here, the selection signal is a signal transmitted from the input unit of the terminal to a signal for clearing or clearing the text message.

In addition, the selection signal may be any key signal or touch signal preset in the terminal.

Subsequently, if the selection signal is received in step S401, in step S402 it is checked whether the shaking of the terminal is detected.

Subsequently, if the shaking of the terminal is detected in step S402, in step S403, it is checked whether the detected shaking of the terminal is a shake of a predetermined threshold or more in the terminal.

Subsequently, if a shake above the threshold occurs in step S403, a secreting signal is generated in step S404.

Subsequently, the secreting is executed by the secreting signal generated in step S406 (S405).

If the selection signal is not received in step S401, the secretion ends (S406).

In addition, even if the shaking of the terminal is not detected in step S402, or even if the shaking is detected, if no shaking occurs above the threshold in step S403, the secretion is terminated (S406).

5 is a flowchart illustrating a personal information decryption method according to another embodiment of the present invention.

Referring to FIG. 5, the terminal checks whether a selection signal has been received (S501) in order to decrypt the non-engraved display information.

Subsequently, if a selection signal is received in step S501, in step S502 it is checked whether the shaking of the terminal is detected.

Subsequently, if the shaking of the terminal is detected in step S502, it is checked in step S503 whether the detected shaking has occurred in the terminal more than a preset threshold.

Subsequently, if a shake above the threshold has occurred in step S503, a decryption signal is generated in step S504.

Subsequently, decryption is executed (S505) by the secretion cancel signal generated in step S504.

If the selection signal has not been received in step S501, de-secreting is terminated (S506).

In addition, even if the shaking of the terminal is not detected in step S502, or even if the shaking is detected, if no shaking occurs above the threshold in step S503, the deactivation is terminated (S506).

6 is a flowchart illustrating a personal information secreting and decrypting method according to an embodiment of the present invention.

Referring to FIG. 5, the terminal checks whether a selection signal has been received (S501) in order to decrypt the non-engraved display information.

Referring to FIG. 6, the terminal checks whether a selection signal has been received (S601) in order to decrypt and de-secret display information.

If the selection signal is not received in step S601, the secreting and de-secreting are terminated (S6609).

Subsequently, if a selection signal is received in step S601, in step S602 it is checked whether the shaking of the terminal is detected.

Subsequently, if a shake is detected in step S602, it is checked whether the shake detected in step S603 occurs more than a preset threshold in the terminal.

If the terminal does not detect a shake in step S602 or if a shake above a threshold does not occur in step S603, the sparking and the clearing of the spark are ended (S609).

Subsequently, if a shake above the threshold occurs in step S603, in step S604, it is checked whether the current display information is in a non-enable state.

If the display information is not in a sparking state in step S604, a sparking signal is generated in step S605.

Subsequently, the display information is secreted (S606) by the secreting signal generated in step S605.

If the display information is in a secret state in step S604, a clearing signal is generated in step S607.

Subsequently, the display information in the secret state is de-secreted by the secret release signal generated in step S607.

As described above, the portable terminal having the information secreting function and the information secreting method according to the present invention can prevent personal information of a user who uses the portable terminal from being exposed to others. Furthermore, there is an advantage that the damage caused by the information exposed to others by using the mobile terminal in public places such as subways and buses can be reduced.

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed.
