Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1 , the hidden password input system according to an embodiment of the present invention includes a page generation unit 100 , an output control unit 200 , an input control unit 300 , and an authentication execution unit 400 . can be

First, the page generating unit 100 generates an output page and an input page that are output on the display screen of the device, and transmits them to the output control unit 200 .

Here, the page generating unit 100 generates an output page and an input page by combining and configuring various windows, and the windows at this time are a keypad window 10 , an input window 20 , and a message window 40 to be described later. , and a function command display window 30 and advertisement windows 51 and 52 . Here, a detailed description of the windows will be described later in the page configuration.

The page generator 100 determines whether to output the output page and the input page according to each embodiment, and serves to selectively output any one of the output page and the input page.

Here, each of the above embodiments is various, such as when the user enters a password in a user authentication mode, when a user command to output and edit a specific window is input by the user's key input, etc. The output order of the output page input page of the page generator 100 will be described in detail in a password input method later.

The page generator 100 may output the output page and the input page according to a preset time.

For example, in the case of the output page, the page generation unit 100 may set variously, such as 2 seconds, 3 seconds, 4 seconds, etc. as a time sufficient for the user to sufficiently check the identification marks, and such an output time can be set by the user. The output time of each page can be set through options to be described later.

The output control unit 200 receives the output page and the input page from the page generation unit 100, and outputs the output page and the input page to the display unit of the device for a preset output time. .

Here, the output control unit 200 may be programmed according to the type of each device so that the output page and the input page are output to the display unit of the device by receiving the signal of the page generating unit 100 .

The input control unit 300 serves to detect a user's touch when the input page is output, receive an input key, and transmit the received input key to the authentication execution unit 400 .

Here, the input control unit 300 may apply a known touch screen capacitive method to detect a user's touch on the input page. However, as an embodiment, the input control unit 300 may apply various sensing methods, such as a pressure sensing method, of course.

The authentication execution unit 400 is a configuration for determining user authentication, and when the user inputs a password on the input page, it determines whether the user is authenticated and whether to release the security.

On the other hand, in the present invention, the arrangement position of the identification mark displayed on the keypad window 10 of the output page is changed to random every time it is outputted. Therefore, the authentication execution unit 400 must perform user authentication in response to the identification display that is changed every time it is output.

Accordingly, the authentication execution unit 400, the input key and the password through the position and input sequence of the input key received from the input control unit 300, and the stored password through the arrangement position of the key displayed on the output page. can be compared to determine whether or not to authenticate according to the match.

In other words, the authentication execution unit 400 decodes and interprets the input value of the input key through the input position and input sequence of the input key with respect to the arrangement position of the key (identification mark) displayed on the output page, By comparing the above-described input value with the stored password, it is possible to determine whether to authenticate according to the match.

Hereinafter, the configuration of the output page and the configuration of the input page will be described in detail.

First, the configuration of the output page will be described with reference to FIG. 2 .

Referring to the drawings, the output page includes a keypad window 10 in which identification marks are arranged and displayed.

Here, the keypad window 10 may be configured such that the input function is not activated so that the input key cannot be generated even when the user inputs the key. In this case, the input control unit 300 is configured to receive an input key by sensing a user's touch when an input page is output.

Alternatively, the keypad window 10 may be configured to activate an input function so that an input key is generated when a user inputs a key so that the user can input a password. In this case, the input control unit 300 is configured to receive the input key by sensing the user's touch when the output page and the input page are output, and in detail, the input key is continuously received from the output page to the input page. can be

As described above, the output page can selectively configure whether or not the input function of the keypad window 10 is activated according to various embodiments, and an embodiment thereof will be described later.

On the other hand, the keypad window 10 is set by randomly changing the arrangement position of the identification marks at each output.

Accordingly, according to the present invention, since the same location is not input each time the password is input, it is possible to make it difficult for a third party to expose and duplicate the password, and it is possible to input the password more safely and improve security.

The output page may include a first advertisement window 51 in which first advertisement information is displayed. Here, the first advertisement information may include a logo of a specific company, but is not limited thereto.

In the drawing, the first advertisement window 51 is located above the keypad window 10 . However, in this embodiment, the output page may position the first advertisement window 51 under the keypad window 10, or the first advertisement according to horizontal and vertical conversion of the display unit screen. The arrangement structure of the first advertisement window 51 and the keypad window 10 may be variously configured such that the window 51 may be positioned on the side of the keypad window 10 .

Hereinafter, the configuration of the input page will be described in detail with reference to FIG. 3 .

Referring to the drawings, the input page includes an input window 20 that allows a user to input a password.

Here, the input window 20 is configured such that the identification marks are not displayed and the input function is activated. In this case, the input window 20 is configured such that the undisplayed identification marks have the same arrangement as the identification marks of the keypad window 10 of the above-described output page.

As described above, since identification marks are not displayed in the input window 20, it is possible to prevent the password from being exposed to a third party, thereby improving security.

The input page may further include a message window 40 , a function command display window 30 , and a second advertisement window 52 .

First, the message window 40 may display a page usage guide or a usage guide message to the user. The message window 40 may be located at the lower end of the screen as shown in (a) of FIG. 3 .

The message window 40 may include various messages, and as shown, a message 'Enter a password' may be displayed. However, this is an embodiment, and the message window 40 may display various other usage guide messages.

Next, the function command display window 30 serves to request the output of the output page according to a user's input and to perform an editing function of the input key. The function command display window 30 may be located at the lower end of the screen as shown in FIG. 3B .

Specifically, the function command display window 30 may be configured to include a show key and a Delete key as shown.

The show key causes the keypad window 10 of the output page to be output when a key is input. Specifically, the show key is used when the user does not confirm or does not remember the identification mark position of the keypad in the previous output page, so that the user can check the identification position of the keypad window 10 again.

The delete key serves to delete input information of the input key when a key is input. The deletion key deletes information on the input key when the user makes a mistake in password input so that the password can be re-entered.

Meanwhile, in the drawing, the function command display window 30 shows only the show key and the delete key, but it goes without saying that other function command keys may be included.

In addition, the function command display window 30 can be displayed with characters such as the show key and the delete key, but in one embodiment, if the function command can be confirmed to the user, it is applicable to various images.

The second advertisement window 52 includes second advertisement information, and is configured on the input page and serves to recognize advertisements to the user when a password is input.

Here, the second advertisement information is composed of information related to the first advertisement information, and may be composed of an advertisement target item in the first advertisement window, a logo of a company, a corporate identity (CI), or a trademark.

For example, when the first advertisement information includes advertisements for a specific manufacturer or a specific advertisement product, the second advertisement information is a trademark of the advertisement product of the specific manufacturer or the advertisement target product displayed in the first advertisement information. can be composed of

As described above, in the present invention, the first advertisement window 51 is displayed on the first output page, and the second advertisement having advertisement contents linked to the advertisement contents of the first advertisement window 51 on the next input page. By continuously displaying the window 52, the user can increase the advertisement recognition effect to further improve the advertisement effect.

Meanwhile, the second advertisement window 52 may be displayed on a location display unit 60 to be described later as shown in FIG. 3C .

Since the identification mark is not displayed on the position display unit 60 of the input page, the second advertisement window 52 can be formed in the portion where the identification mark is displayed, and the position display unit 60 also allows the user to input a password. This is because the advertisement effect can be improved by forming the second advertisement window 52 on the position display unit 60 as a part that is more recognized in order to do so.

However, the display of the second advertisement window 52 on the location display unit 60 in this way is an embodiment. Of course, it may be disposed on the upper or lower part of the .

Hereinafter, the position and form of the identification mark on the output page will be described.

Referring to FIG. 4 , the identification mark of the output page may be formed in a semi-transparent circle as shown in (a), and is formed in a semi-transparent square shape as shown in (b) and the outline is formed by a dotted line. can be

Here, the identification mark of the output page is shown as an example of a translucent circular or rectangular configuration so that the user can easily check the identification mark and maximize the image of the background screen, but other various shapes, etc. Of course it is possible.

Hereinafter, the position display unit 60 formed in the input window 20 of the above-described input page will be described.

The input window 20 may be configured to include a position display unit 60 of a preset shape at each key position made of identification marks to guide the user's key confirmation or key input position, and such position display unit ( 60) is possible in various embodiments as follows.

Referring to (a) of FIG. 5 as an embodiment, the position display unit 60 may be formed in a circular shape having an outline of a transparent line and a semi-transparent inside.

Alternatively, the position display unit 60 may be formed in a circular shape having a dotted outline and a transparent inside, as shown in FIG. 5B .

Alternatively, as shown in FIG. 5(c) , the position display unit 60 may have a dotted outline and a semi-transparent rectangular shape.

Alternatively, as shown in (d) of FIG. 5 , the position display unit 60 may have an outline of a transparent line and is formed to be transparent inside, so that it may be displayed substantially transparently on the screen. In this case, the present invention can minimize the influence on the display background screen, thereby improving the aesthetics, as well as meeting the various tastes of the user.

In addition, although not shown, the position display unit 60 may be formed as a single point in the center of each input position, and various embodiments are possible.

As described above, the input page according to the present invention may be configured to include various input windows, and further, a page that does not include an input window may be an embodiment of the input page. Of course, in the case of this embodiment, it goes without saying that the setting of the input values for the coordinates and the area of the touch panel corresponding to the arrangement of the identification mark output from the output page and the target area must be provided.

Therefore, in the case of the above embodiment, there is no indication of any position or area on the input page, but when the user remembers the keypad shape and arrangement output on the output page and inputs a touch at the corresponding location, the device may recognize that the corresponding key is input. can

Accordingly, in the case of the embodiment in which the position display unit has a transparent outline and a transparent interior in the above-described embodiment, it may be used in substantially the same meaning as that in which the input window is not displayed.

Hereinafter, a password input method (hereinafter referred to as a 'password input method') using the hidden password input system according to an embodiment of the present invention will be described. Here, since the hidden password input system has been described above, a detailed description of its configuration will be omitted. Hereinafter, a password input method and an output page and an output order of the input page will be described.

In this way, when the output page and the input page are generated, (b) the page generating unit 100 selects and outputs any one of the output page and the input page.

In this case, the page generating unit 100 may select and output an output page and an input page according to the following embodiments, respectively.

In a first embodiment, the page generating unit 100 may output the output page in the user authentication mode.

Here, the page generating unit 100 outputs the output page by changing the arrangement position of the identification marks every time the output page is output once.

On the other hand, the user authentication mode is a mode in which the user wants to input a password, and when the user turns off the display screen for a moment and then turns it on again, it is not regarded as a user authentication mode.

In a second embodiment, the page generator 100 may output the input page after outputting the output page for a preset output time.

Here, the output time of the output page is a time that the user can sufficiently recognize the identification mark, and the time can be set in seconds, such as 2 seconds, 3 seconds, 4 seconds, etc., and the page The generating unit 100 outputs the input page as soon as the output page is output and the set output time elapses.

In a third embodiment, when a user's output page output command is input through the function command display window 30 (show key input), the page generating unit 100 includes the output page including the keypad window 10 . and outputting the input page when the output command is released.

Specifically, the page generator 100 may be configured to output the output page including the keypad window 10 when an input signal is received by the user inputting the show key when the input page is output.

Alternatively, the page generator 100 may be configured to output the input page including the input window 20 when an input signal is received by the user inputting the delete key when outputting the input page.

Meanwhile, the page generating unit 100 outputs an output page including the keypad window 10 while the user touches the show key and the show key is input, and when the user releases the touch from the show key, the output An input page can be output as the page output command is canceled.

Alternatively, the page generating unit 100 sets the release of the output command based on the time, and sets the output command to be released when the set time elapses after inputting the output command, so that the user inputs the show key to the keypad window ( When a set time elapses after the output page including 10) is output, the input page including the input window 20 may be automatically output.

When the output page and the input page are output as described above and the user inputs the password, (c) the input control unit 300 detects the user's touch when the input page is output and inputs it to the authentication execution unit 400 send the key

In this case, the input control unit 300 may delete the input information of the input key when the user inputs the delete key and the user's input key delete command is input.

When the output time of the output page elapses after the set output time, the page generator 100 outputs the input page as shown in FIG. 7C ( S13 ).

Meanwhile, before outputting the input page, the page generating unit 100 may selectively output the input page including the message window 40 for a preset period of time as shown in (b) of FIG. 7 . In this case, the message window 40 may apply 'enter a password' as a password input guide to the user as shown, but various other contents may be applied, of course.

Furthermore, in the drawing, the message window 40 was output in the previous step of FIG. The input page output including one message window 40 may be deleted in some cases.

Next, when the input page is output as described above, the user inputs a password (S14).

Meanwhile, in the input page, as shown in FIG. 7C , a function command display window 30 including a show key and a delete key may be output. Accordingly, if the user needs to reconfirm the identification display on the keypad window 10 after outputting the above-described input page, the user may input the above-described output command (show key).

In this case, the page generating unit 100 may output an output page according to the user's output command input as shown in FIG. 7(c), and when the output command set after outputting the output page is released, The page generator 100 may output an input page as shown in FIG. 7D .

When the user inputs the password in this way, the input control unit 300 receives the input key and transmits the input key to the authentication execution unit 400, and the authentication execution unit 400 performs user authentication (S15).

On the other hand, if the user does not input the password, the process of outputting the input page is performed again after outputting the previous output page.

After that, the authentication execution unit 400 performs user authentication and when the user authentication is completed (S16), the security release (S17) is performed.

Here, if user authentication is not completed, the authentication execution unit 400 transmits a signal to the page generation unit 100, and then the page generation unit performs a process of re-outputting the input page after outputting the previous output page. .

Next, a password input method according to the second embodiment will be described with reference to FIGS. 8 and 9 .

8 and 9 , first, the page generator 100 generates an output page and an input page ( S21 ).

Then, an input page is output as shown in (a) and (b) of FIG. 8 . At this time, in the input page, a message window 40 with a password input request as the content is output for a preset period of time, and then, when the message window 40 disappears, an input window and a function command display window 30 are output.

In this state, the user inputs an output command (show key) in the function command display window 30 of the input page, and when the output command is input in this way, the page generator 100 is Similarly, the keypad window 10 of the output page is output (S22).

In this way, when the keypad window 10 is output and the user confirms the identification number and the output command is released, the page generator 100 outputs an input page as shown in (d) of FIG. 8 (S23). ).

When the input page is output as described above, the user inputs a password as described above (S24). The authentication execution unit 400 performs user authentication (S25), and when the user authentication is completed (S26), the security is released (S27).

Hereinafter, a password input method according to the third embodiment will be described with reference to FIG. 10 .

Referring to FIG. 10 , first, when the user authentication mode starts, the page generating unit 100 outputs an input page including a function command display window as shown in FIG. 10A . Here, the function command display window is a lock image in the form of a lock as shown in FIG.

Accordingly, when an output command is input by the user touching the lock image in a state in which the input page including the function command display window is output as described above, the page generating unit 100 is configured as shown in FIG. Similarly, the keypad window 10 of the output page is output (S22).

Thereafter, when the output time of the output page elapses the set output time, the page generator 100 outputs the input page as shown in FIG. 10C .

On the other hand, when the input page is output as described above, the user may input a password. At this time, the user may not accurately remember the identification mark of the previous keypad window 10 or it may be necessary to reconfirm the identification mark.

In this case, the user can input a show key, which is an output command, and when the show key is input in this way, as shown in FIG. is output so that the user can check the identification mark again.

As described above, when the user confirms the identification number and the output command (show key) is released , the page generating unit 100 outputs an input page as shown in FIG. do. Here, since the user authentication process after inputting the user's password goes through the same process as the above-described user authentication process, a detailed description thereof will be omitted.

On the other hand, the password input method according to the first to third embodiments described above shows a password input method according to the case where the input function of the keypad window 10 is not activated in the output page.

However, as described above, the page setting unit 100 may be configured so that the input function of the keypad window 10 is activated, and accordingly, an embodiment in which an input is possible in an output page is also possible, so that an embodiment in which a password input is possible is also possible. do.

Accordingly, a password input method according to the fourth embodiment in which the input is set to be activated on the output page as described above will be described.

First, the page generating unit 100 generates an output page and an input page, and then outputs the output page when the user authentication mode starts.

At this time, the output page includes the keypad window 10 in which the input function is activated. Therefore, the output page allows the user's password input, so that it is possible to generate an input key according to the user's touch during the output time.

After that, when the output page output time is set after the output time has elapsed, the page generator 100 outputs the input page.

When the input page is output in this way, the user can input the password through the input window, and it is also possible to use the show key and the Delete key of the above-described function command display window 30 .

Next, when the user inputs a password, the input control unit 300 receives the input key and transmits it to the authentication execution unit 400 .

On the other hand, since the output page and the input page each have an input function activated according to the above description, the input control unit 300 may receive an input key by sensing a user's touch from both the output page and the input page. have.

Accordingly, the input control unit 300 may receive each information of the input key received from the output page and the input key received from the input page, combine them, and transmit it to the authentication execution unit.

For example, in the first embodiment, when the user inputs all passwords during the output time of the output page, the input control unit 300 receives the input key received from the output page and transmits it to the authentication execution unit 400 . do.

Next, in the second embodiment in which the user inputs all of the passwords when outputting an input page rather than an output page, the input control unit 300 receives the input key received from the input page and uses the authentication execution unit 400 . send to

Next, in the third embodiment, in which the user inputs a part of the password during the output time of the output page and inputs the remainder of the password during the output time of the subsequent input page, the input control unit 300, the input key received from the output page and each of the input keys received from the input page are sequentially combined from the output page to the input page and transmitted to the authentication execution unit 400 .

That is, when the user inputs '12', which is the first two digits of the password '1234' on the output page, and inputs the remaining password '34' on the input page, the input control unit 300 performs the input received from the output page. '1234' obtained by continuously combining the key '12' and the input key '34' received from the input page is transmitted to the authentication execution unit 400 .

Thereafter, the authentication execution unit 400 performs user authentication, and when user authentication is completed, security release is performed, and when authentication is not completed, an output page is output so that the user can re-enter the password. .

Meanwhile, the present invention can be applied to various devices including a mobile terminal, a computer terminal, a door lock, an ATM machine, a credit card payment machine, and a safe that require password input and authentication thereof.

For example, when the device is a touch panel type, the output control unit 200 and the input control unit 300 may output an output page and an input page through a touch screen, and receive an input key.

Alternatively, unlike the above, the present invention can be applied to a device having an analog-type button-type keypad and a display screen.

In this case, the present invention provides a page generation unit for generating an output page including a keypad window on which identification marks are displayed in which the arrangement positions of the identification marks are changed each time they are output, and a page generation unit for receiving the output page from the page generation unit, an output control unit for outputting the output page to a display unit; an input control unit for receiving an input key from the input module of the device when the output of the output page is finished; a position of the input key received from the input control unit; It may be configured to include an authentication execution unit that compares the input sequence and the stored password through the arrangement position of the keys displayed on the output page and determines whether to authenticate according to whether or not they match.

Here, the input control unit may set the input key reception of the input module in an inactive state while the output control unit outputs the output page.

In addition, the page generator, when the user inputs an input key for entering a password, terminates the output page, thereby preventing exposure of the identification number of the keypad, and furthermore, it is possible to end the output page even in the authentication mode.

Meanwhile, the output page may include the above-described message window and a first advertisement window.

According to the above description, in the present invention, the output control unit 200 is connected to the display unit of the device to output an output page, and the input control unit 300 is connected to the keypad of the device to receive an input key. can do.

That is, in the present invention, as described above, through the output control unit 200 and the input control unit 300, the output means and the input means are separated as well as the touch panel type device in which the output means and the input means are the same as the display screen and the keypad. It can be applied to an analog-type device that has been made, and it can be applied to devices of various other configurations to increase the effectiveness.

Furthermore, referring to FIG. 11 , the present invention may include a setting control unit so that a user can edit an output page and an input page, or correct or edit a password.

The setting control unit may output a setting window composed of various options (menus) to perform the above-described various functions on the screen of the display unit.

Here, the above-described options may set the output time of the output page and the input page associated with the page generation unit, and may include various menus related to password setting associated with the authentication execution unit.

For example, the above options are configured to set whether to use the lock screen of the display unit, the number of password digits, password correction/editing, the color of the location display unit, the output time of the background screen and the output page, etc., and a backup PIN for unlocking the password when the password is lost. An input menu may also be configured.

In the drawings, the options include a setting screen menu including whether to use a lock screen, number of password digits and password setting, a password input keypad setting menu, a background screen setting menu, a random keypad operation time menu, and a PIN setting menu for backup. It goes without saying that various embodiments are possible with one embodiment.

Meanwhile, although not shown, the hidden password input system may configure various embodiments as follows.

First, the page generating unit may increase the output time of the output page as the number of times the user's password input error increases.

This may mean that the increase in the number of password input errors may mean that it may be difficult for the user to check the identification marks displayed on the keypad window.

Accordingly, as described above, as the number of password input errors increases, the page generator increases the output time of the output page to increase the exposure time of the identification mark displayed on the keypad window, and through this, the user can obtain a password from the identification marks displayed on the keypad window. It is possible to more easily confirm and memorize the position of the input key.

Second, the input control unit, when the number of password input errors of the user exceeds a preset number of times, stops receiving the password input key for a preset time, and is configured to enable password input after canceling the password input stop, improving security can do it

In this case, the time for which the reception of the password input key is stopped can be set in various ways, such as generally 3 minutes to 5 minutes. However, such a waiting time may cause inconvenience to a user who is in a hurry to use the device.

Accordingly, when the number of times the user's password input error exceeds a preset number of times, the page generating unit outputs the second advertisement window on the input page, and when the user touches the second advertisement window to check all advertisement contents It may be configured to release stop password input. Accordingly, the user can use the device more quickly by shortening the waiting time, and in addition to this, an advertisement effect can be obtained.

Third, the page generator may further increase the output time when the first advertisement window is output from the output page.

Since this can reduce the concentration for checking the identification mark of the keypad window to the user as much as the first advertisement window is output, when the first advertisement window is output, the output time of the output page including the keypad window with the identification mark is increased to increase usability can improve

Although the present invention has been described with reference to the embodiment shown in the drawings, which is merely exemplary, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
