Description

Device for inputting a terminal's padword and its method {INPUT APPARATUS OF PASSWORD IN TERMINAL AND METHOD THEREOF}

The present invention relates to a pad input device and a method of the terminal.

Conventional methods of locking and unlocking a mobile terminal or a smartphone or door lock device include iris recognition or face recognition technology, pattern, and password recognition methods. However, the method of unlocking the currently used smart phone mainly consists of a 4-digit password number input method and a pattern input method. However, this method is very frequently exposed when a user and a neighbor are in a position where the display of the device on the front of the terminal can be recognized or when the device is placed on the table in an opposite situation such as a coffee shop.

In addition, the conventional facial recognition technology is capable of recognizing when a user is asleep or outputting a photograph or a face image of the user on a monitor screen.

According to an embodiment of the present invention, a password input device and a method of a terminal having enhanced user convenience and security are provided.

According to an embodiment of the present invention, a pad input device for a terminal, comprising: a tilt sensor unit that acquires tilt information input from a user through a screen for tilt input displayed through a display unit of the terminal; And computer program code for storing gradient information obtained through the tilt sensor unit 5 as a pad word under the control of the computer processor of the terminal as a pad in the storage unit of the terminal. do.

According to an embodiment of the present invention, user convenience and security are enhanced.

The present invention is superior in security compared to the conventional four-digit password input method or pattern recognition method, and even if the user is in a position where monitoring is possible when the device liquid crystal quench or password is input, the device cannot be recognized by the surrounding people even if they are facing It has the advantage that it can be unlocked naturally by blinking everyday without hiding the secret value by covering one eye.

In addition, it is almost impossible to try even if you remember the blink pattern because you have to enter it in the state where the first facial recognition was performed, even if all of the users' eyes blink opposite to each other. Therefore, it can be said that the present invention has superior security than the conventional input method. In particular, when the present invention is applied to an application field such as a door lock device, it is close to impossible for the companion to recognize each blink of both eyes.

In addition, it is very difficult to recognize a wink in the case of a user with small eyes or wearing glasses. However, in the present invention, the recognition rate is recognized through an algorithm that recognizes the eye by raising the mouth and wrinkles at the boundary between the eyes and nose when winking. Increased.

In addition, in public places such as open-air cafes, restaurants, and coffee shops, while seeing the use of opposite sex, it may be mistaken as a wink to oneself, and the opposite reason may be mistaken, but it is not only conducive to eye health, but also a device applied with this technology Assuming that a lot of people use it in a public place, a very interesting situation in which everyone winks can occur and a brighter and more enjoyable mobile life can be expected. In addition, according to the present invention, when a terminal learner and a neighbor who remembers a blinking pattern attempts to decrypt a password, the face of the attempter is transmitted, and thus it can be expected that the security is excellent and the loss recovery rate will be increased.

In addition, the present invention has the inconvenience of using both hands unless the terminal is placed in a fixed position such as a table to release the password, but the present invention has the effect of releasing the password with one hand, so it is not necessary to use it while driving. There is no need to use both hands, and it is easy to enter a password without looking at the display, which helps safe driving.

The computer processor 1 loads and executes the computer program code into the memory 3 to execute the tilt sensor unit 5, the display unit 7, the storage unit 9, the camera unit 11, and the vibration unit 13 ) Can control each first operation.

The memory 3 is loaded with computer program code that is operated under the control of the computer processor 1, and the memory 3 is volatile or non-volatile, such as, for example, ROM, RAM, or flash ROM. It can be a medium.

On the other hand, the memory 3 may store a computer program code for generating a password according to an embodiment of the present invention, and in the detailed description of the present application, a computer program code for generating and managing a password is described in particular as a 'password for convenience. Management Computer Program Code. '

The display unit 7 may display a screen for tilt input.

The storage unit 9 stores computer program code loaded and operated in the data or memory 3. Here, the data may be data necessary for computer program code to be executed or data necessary for controlling other components.

The storage unit 9 can also store a password. Here, the password may be a password generated by one or more embodiments of the present invention.

The vibrator 13 may vibrate the terminal.

The camera unit 11 may acquire an image. For example, the camera unit 11 may acquire facial motion information, where the facial motion information may be image information captured by the user's face.

The tilt sensor unit 5 may acquire tilt information input from a user through a screen for tilt input displayed through the display unit 7. Here, the screen for inputting a tilt includes an object that is moved according to the tilting direction of the terminal, and the tilt information includes a moving direction of the object.

On the other hand, according to an embodiment of the present invention, the screen for tilt input may include a path through which an object may move, and the object may be moved along the path.

In addition, the path is connected to at least two or more destinations, and if an object is located at any one of the two or more destinations, the password management computer program code may perform at least one of the following operations.

 i) vibrating the vibrating part 13,

ii) A screen is displayed on the screen for tilt input indicating that the object is located at the destination.

iii) Outputs an acoustic signal indicating that the object is located at the destination through the speaker (not shown) of the terminal.

On the other hand, when the screen for tilt input is displayed and the terminal is flipped at least once, the computer program code may additionally display that the terminal is flipped on the screen for tilt input. For example, the color of the object on the screen for tilt input may change, or a text indicating that the terminal has been flipped, such as 'Rotation', may be displayed.

Meanwhile, the object may have a shape such as a ball or an arrow, but these are exemplary, and the present invention is not limited to a ball or an arrow.

For more detailed description of the tilt input screen, refer to the descriptions of FIGS. 6 to 8.

The password management computer program code may store the tilt information obtained by the tilt sensor unit 5 as a password in the storage unit 9. Here, the tilt information may include information on how many times the object moves and / or information on how many times the terminal has been flipped.

As an alternative, the password management computer program code combines the tilt information obtained through the tilt sensor unit 5 with the blink information of the eye extracted from the facial movement information acquired through the camera unit 11 as a password storage unit. (9) can be stored.

The password management computer program code displays a screen for inputting an eye blink on the display unit 7 to acquire facial information, and a user can blink an eye while looking at the face of the user (user) on the eye blink input screen. Here, the password management computer program code analyzes the image input through the camera unit 11 and stores it as blink information of the eye whenever it is determined that the user has blinked the eye. The blinking information of the eye may be stored by recognizing the blinking of the eye as a Morse code, as exemplarily illustrated in FIG. 13. For example, the blinking of the left eye (wink) may be determined as a short point, and the blinking (wink) of the right eye may be determined as a long point, and the blinking information of the eye may be stored.

Referring again to FIG. 13, if you want to register a password of HELLO, the left eye blinks 4 times (wink) / the left eye wink once / the left eye wink once, the right eye wink long, the left eye wink twice / the left eye wink twice. It is possible to do this once, long wink of the right eye, twice wink of the left eye / three winks of the right eye.

For a more detailed description of this, please refer to the description below in FIG. 9.

On the other hand, when the password management computer program code extracts the blink information of the eye from the facial motion information, it can extract the blink information of the eye according to a predetermined criterion.

Here, the predetermined criterion is, for example, a criterion for distinguishing whether or not the user has blinked an eye by a doctor. For example, in the facial motion information, whether or not a finger is used for the eyes may be a standard, and it is determined that the eye is blinked by the user's doctor only when the finger is not used. See FIG. 12 for this. As can be seen from the drawing of FIG. 12, the wrinkle shape on the eye formed by the finger is different from the wrinkle shape generated by blinking the eye naturally.

For another example of a predetermined criterion, it is possible to determine whether the eye is blinked by a user's doctor by looking at the shape of wrinkles and / or facial changes on the eyes. This is because there is a difference between a wrinkle generated when a user blinks an eye by a user's doctor and a wrinkle created forcefully by an external force. For this, see FIGS. 10 and 12.

In the above-described embodiment, the operation of storing the password (hereinafter referred to as 'password registration operation') in the password management computer program code has been described. Meanwhile, the above-described password management computer program code may also perform an operation (hereinafter referred to as 'password authentication operation') of determining whether a previously stored password and a password received from a user match each other. The password authentication operation will be described in detail with reference to FIG. 3.

2 is a view for explaining a password input method according to an embodiment of the present invention.

When the user accesses the terminal or there is a request to access a predetermined application installed on the terminal, the terminal inquires whether there is a registered password or not, and asks whether to register the password, and the user registers a password for such an inquiry Ask to do.

When the terminal requests a password registration from the user (S101), a screen for inputting a slope is displayed (S103).

The user inputs tilt information on the screen for tilt input (S105).

The terminal stores the tilt information received in step S105 as a password (S107).

The embodiment of FIG. 2 can be modified as follows.

When the user requests a password registration from the user, the terminal displays a screen for inputting a tilt, and when a user inputs tilt information on the screen for inputting a tilt, the screen again displays a screen for inputting a blink and displays a screen guiding the user to blink. . The screen for inputting an eye blink includes a window showing a face of the current user of the terminal and a button for instructing to input the current face. The terminal combines the tilt information and the blink information received from the user and stores it as a password.

The embodiment of Figure 2 can be modified differently. That is, the screen for inputting the blinking of the eye is displayed first, and when the blinking information is input, the screen for inputting the tilt is then displayed, and when tilting information is input through the screen for inputting the tilting, the two are combined and stored as a password.

3 is a view for explaining a method for password authentication according to an embodiment of the present invention.

Referring to FIG. 3, when a user requests a login to access a terminal or to execute a specific application installed in the terminal (S201), the terminal displays a screen for inputting a slope (S203).

When the description information is input through the screen for tilt input (S205), the terminal compares with the previously stored password (S207), and if it matches (S209: Y), allows login (S211), and if it does not match (S209: N) ) Do not allow login.

The embodiment of FIG. 3 can be modified, similar to the modification of the embodiment of FIG. 2 above.

When the terminal requests a login from the user, the terminal displays a screen for inputting a tilt, and when a user inputs tilt information on the screen for inputting a tilt, the terminal displays a screen for inputting a blink and displays a screen for guiding the blinking of the eye. The screen for inputting an eye blink may include a window showing a face of the current user of the terminal, a status display unit 7 indicating a password input status, and a button instructing the user to store the password input in the status display unit 7.

The embodiment of FIG. 3 can be modified differently. That is, when the blinking input screen is first displayed and the blinking information is input, the tilt input screen is displayed, and when tilt information is input through the tilt input screen, a combination of both and a previously stored password is compared. do. The subsequent operation is the same as the embodiment shown in FIG. 3.

In the embodiment of Fig. 3, the password management computer program code, if the blink information received from the user does not match the previously stored password, the user's video is captured, stored, or transmitted to an external device (such as a police station server). have.

 4 and 5 to 8 are views for explaining a screen for tilt input according to an embodiment of the present invention.

Referring to these drawings, the tilt input screen includes at least a path 22, a destination 24a, 24b, 24c, and 24d, an object 26 having a ball shape, a status display unit 28 indicating a password input status, and a terminal. And an inverted display unit 32 indicating whether it has been flipped more than once.

When the terminal is tilted as shown in Fig. 5, the object 26 is moved to the upper destination 24d. When the object 26 arrives at the destination 24d, the password management computer program code i) vibrates the vibrating unit 13 of the terminal, ii) displays on the screen for tilt input indicating that the object is located at the destination , iii) The object is located at the destination through the speaker of the terminal.

On the other hand, whenever the object 26 is moved to a specific destination, the password management computer program code fills and displays the password one by one in the status display unit 28.

The path 22 is intended to provide a convenient way for the user to move the object 26, and the user can move the object 26 while viewing the path 22. The path 22 is preferably provided, but not necessarily, and is a component that can be added by the present inventor as necessary.

The inverted display unit 32 changes color whenever the terminal is turned over. For example, the screen for tilt input displayed on the terminal is displayed in red when the user flips it once and then returns it. Before entering the password, the screen for tilt input is flipped over again and displayed in blue when it is restored. Referring to FIG. 8, it is exemplarily shown to flip the terminal once, and the state of the screen for tilt input at this time is illustrated. The inverted display 32 is displayed in red as can be seen in FIG. 8.
