In FIG. 1, although the display unit 101 of the user terminal 100 is implemented as a touch screen method and functions as an input unit at the same time, the input unit is implemented as a keyboard or keypad method, for example. It may be provided separately from.

The user terminal 100 according to an embodiment is a digital device having a computing capability by mounting a microprocessor and having a memory means such as a tablet PC, a smartphone, a personal computer, a workstation, a PDA, a web pad, a mobile phone, a navigation device, and the like. It should be understood as a term encompassing.

The fingerprint sensor unit 110 according to an embodiment may be implemented as a slide type or an area type. 1 and 2 illustrate the slide type fingerprint sensor as an example, but is not limited thereto. The slide type fingerprint sensor 110 reads fragmentary fingerprint images by sensing a fingerprint of a finger moving in a sliding manner, and then matches the fragmented fingerprint images into a single image to implement a fingerprint recognition in a manner that realizes an intact fingerprint image. Perform. On the other hand, in the case of an area-type fingerprint sensor, a single fingerprint image is sensed by sensing a fingerprint that is fixed on the sensor without collecting a fragment fingerprint image and matching the image into a single image. Performs fingerprint recognition.

FIG. 2 shows an example of a fragmentary fingerprint image obtained by the slide type fingerprint sensor 110 shown in FIG. 1.

For example, when the user moves the thumb against the fingerprint sensor unit 110 in a sliding manner, partial partial images P1 to P4 are obtained continuously.

That is, the fingerprint images of the user are acquired sequentially in a fragmentary but continuous form. The fragment fingerprint images read from the fingerprint sensor 110 are matched to one fingerprint image.

According to an embodiment, the matched fingerprint image may be used as a means for verifying the validity of the corresponding user by comparing with the registered fingerprint image.

That is, the registered fingerprint image of the user may be stored in a database (not shown) of the user terminal 100, and the fingerprint image acquired through the fingerprint sensor 110 is compared with the fingerprint image stored in the database. User authentication can be performed.

According to another exemplary embodiment, the matched fingerprint image may be compared with one or more registered fingerprint images to function as a command for performing a specific operation.

For example, specific operations may be matched and stored with respect to the fingerprint of each finger of the user, and if the matched fingerprint image acquired by the fingerprint sensor 110 matches the fingerprint image of the specific finger, the specific matched with the fingerprint image may be matched. The operation can be done. This is referred to herein as a 'quick execution' function.

For example, the first application may be driven when the thumb fingerprint of the true user is recognized, and the user may preset the second application when the index finger fingerprint of the true user is recognized.

Thereafter, if the user moves the thumb to the fingerprint sensor unit 110 in a sliding manner, if the matched fingerprint image obtained by the fingerprint sensor unit 110 matches the fingerprint image of the pre-registered thumb, matching is performed. Operation, that is, driving operation of the first application, is performed.

Referring to FIG. 3, the user terminal 100 according to the present invention includes a fingerprint sensor unit 110 and a screen display unit 130.

The fingerprint sensor 110 may sense a fingerprint from a user's finger, and a detailed description thereof will be omitted since it has been described above.

The screen display unit 130 displays a screen corresponding to the sensed fingerprint on the screen of the user terminal 100. For example, the screen display unit 130 may search for a home screen corresponding to the sensed fingerprint and display the home screen on the screen (see FIG. 4), or search for an account corresponding to the sensed fingerprint and log in with the searched account. The screen can be displayed (see FIG. 7). As another example, the screen display unit 130 may display a hidden page corresponding to the pre-registered fingerprint if the sensed fingerprint matches the pre-registered fingerprint when the hidden page is requested to be displayed while the hidden page is generated. (See FIG. 10). To this end, the screen display unit 130 may further include one or more components to display each screen corresponding to the sensed fingerprint on the screen, which will be described later with reference to FIGS. 4, 7 and 10. do.

The fingerprint register 120 may register a fingerprint of a user corresponding to a home screen.

Here, the home screen may have one or more different modes, and may be a specific main page or a specific folder including a plurality of applications in each mode. The home screen having one or more different modes may be set differently by a user.

Here, each home screen may correspond to each fingerprint of the user. For example, if the fingerprint of the third finger is registered as the main page of the game mode and the fingerprint of the fourth finger is registered as the main page of the SNS mode, the home screen corresponding to the fingerprint of the third finger becomes the main page of the game mode. The home screen corresponding to the fingerprint of the fourth finger may be the main page of the SNS mode.

The home screen search unit 131 may search a home screen corresponding to the fingerprint sensed through the fingerprint sensor unit 110.

Fingerprint sensing and corresponding home screen search may be performed simultaneously with user authentication when the locked state of the user terminal 100 is released.

The home screen display unit 132 may display the screen of the user terminal 100 searched by the home screen search unit 131 on the display unit 101.

The home screen search unit 131 and the home screen display unit 132 may be included in the screen display unit 130 shown in FIG. 3 as a component for searching a home screen and displaying the searched home screen, but is not limited thereto. Instead, the home screen display unit 132 may replace the screen display unit 130.

For reference, the method of displaying the home screen illustrated in FIG. 5 may be performed by the user terminal 100, and the computer-readable recording medium in which the program for executing the steps illustrated in FIG. 5 is recorded in the user terminal 100. Is installed, the steps shown in Fig. 5 can be executed by the recording medium.

First, the user terminal 100 registers each fingerprint of a user corresponding to each home screen (S401).

After S401, the user terminal 100 senses a user's fingerprint for releasing the lock on the screen of the user terminal 100 where the lock is set (S402).

After S402, the user terminal 100 searches for a home screen corresponding to the fingerprint sensed in S402 (S403).

After S403, the user terminal 100 displays the home screen searched for in S403 on the display unit 101 that is the screen of the user terminal 100 (S404).

As shown in FIG. 6, each finger fingerprint of the user is registered corresponding to each mode.

When the screen of the user terminal 100 is set to lock, and the user releases the lock with the fingerprint of the second finger, the display unit 101 of the user terminal 100 is displayed as 'quick execution'. The main page of the baby mode registered in correspondence with the finger fingerprint may be displayed. When the user releases the lock with the fingerprint of the third finger, the display unit 101 of the user terminal 100 displays the user as 'quick execution'. The main page of the game mode registered corresponding to the third finger fingerprint may be displayed.

In addition, although not shown in FIG. 6, when the lock is released by the fingerprint of the fifth finger, a specific folder including a plurality of applications or work files related to a task is displayed on the display unit 101 of the user terminal 100 as a work mode. Can be displayed.

The user terminal 100 according to another exemplary embodiment of the present invention may include a fingerprint sensor unit 110, a fingerprint register unit 120, an account search unit 133, and a login execution unit 134.

The fingerprint sensor 110 may sense a fingerprint of an input user for releasing a lock on a screen of the user terminal 100 in which a lock is set and logging in to his or her account. It is omitted because it is one.

On the other hand, the fingerprint registration unit 120 may match the user's fingerprint for performing the login in the user terminal 100 and the fingerprint of the user sensed through the fingerprint sensor 110 may be stored. For example, when user A, user B, and user C jointly use the user terminal 100, the user terminal 100 may store an account and a fingerprint of each user.

The account search unit 133 may search for an account of the user corresponding to the fingerprint sensed by the fingerprint sensor 110.

The login performing unit 134 logs in the user terminal 100 using the account searched by the account searching unit 133, and displays the screen logged in with the corresponding account on the display unit 101 which is a screen of the user terminal 100. I can display it.

Meanwhile, the account search unit 133 and the login execution unit 134 may be included in the screen display unit 130 shown in FIG. 3 as a component for displaying a screen logged into the account on the display unit 101. However, the present invention is not limited thereto, and the login performing unit 134 may replace the screen display unit 130.

Therefore, when a plurality of users jointly using the user terminal 100 logs in to their account in the locked user terminal 100, they do not enter their ID and password, but simply use their fingerprints. You can log in.

For reference, a method of displaying a login screen using a fingerprint illustrated in FIG. 8 may be performed by the user terminal 100, and the user terminal 100 may read a computer in which a program for executing the steps illustrated in FIG. 8 is recorded. A possible recording medium is provided so that the steps shown in FIG. 8 can be executed by the recording medium.

First, the user terminal 100 matches and stores an account of each user and a fingerprint of the corresponding user (S801).

After S801, the user terminal 100 senses a fingerprint of the user for releasing the lock on the screen where the lock is set (S802).

After S802, the user terminal 100 searches for an account of the user corresponding to the sensed fingerprint (S803).

After S803, the user terminal 100 logs in using the searched account and displays the screen logged in with the corresponding account on the display unit 101 of the user terminal 100 (S804).

As shown in FIG. 9 (b), when a lock is set on a jointly used user terminal 100, when a specific user inputs his fingerprint on the user terminal 100, the user terminal 100 matches the fingerprint. The screen logged in with the account to be displayed may be displayed as shown in FIG.

If the lock setting is released in a manner other than the fingerprint of each user (for example, a password or a pattern input), the user terminal 100 displays a screen logged in with the joint account as shown in FIG. can do.

10 is a block diagram illustrating a configuration of a user terminal according to another embodiment of the present invention, and FIG. 11 is an exemplary view illustrating a process of displaying a hidden page of a user terminal according to another embodiment of the present invention.

As shown in FIGS. 10 and 11, the user terminal 100 according to another exemplary embodiment of the present invention includes a hidden page generator 103, a fingerprint input display unit 107, a fingerprint sensor unit 110, and a hidden page display unit. 140 may be included.

Here, the hidden page generator 103 may generate the hidden page 111 when a request for generating the hidden page 111 is made.

The hidden page 111 may not be displayed from the first generation, or may not be displayed after being displayed for a predetermined time at the time of initial generation, or may be set to continue to be displayed from the first generation.

In the present invention, the meaning of the hidden page 'displayed' means that the 'hidden' state of the hidden page is released to the 'open' state, this 'open' state may mean a 'unlocked state'. In addition, the hidden page 'hidden' may mean that the 'open' state of the hidden page is released 'hidden' state, such a 'hidden' state may mean a 'locked state'.

Alternatively, the hidden page 111 may be set so that the above three settings can be selected by the user.

The hidden page 111 may be generated separately from the basic page 105 provided as a base, and one or more may be generated.

In addition, the symbol 112 representing the hidden page 111 may or may not be displayed along with the symbol 106 representing the basic page 105.

When the symbol 112 representing the hidden page 111 is displayed, the symbol 112 representing the hidden page 111 may be formed to be distinguished from the symbol 106 of the basic page 105. In FIG. 11A, the lock 112 is added to the symbol 112 representing the hidden page 111, but the embodiment is not limited thereto. For example, it may have the same shape as the symbol 106 of the basic page 105 but different colors.

Therefore, when the symbol 112 indicating the hidden page 111 is displayed, the user can easily know whether the hidden page 111 is generated and the number of the hidden pages 111.

Meanwhile, as shown in FIG. 11B, when the display of the hidden page 111 is requested, the fingerprint input display unit 107 may display a fingerprint input request window 121 for requesting a fingerprint input.

In this case, the display request of the hidden page 111 may be variously made. For example, as shown in FIG. 11A, the user takes a swipe gesture while touching the screen to switch the screen on the last basic page 105 (ie, to display the next screen). Or by touching the symbol 112 of the hidden page 111.

As shown in FIG. 11B, the fingerprint sensor 110 may sense a fingerprint from a user's finger. The detailed description of the fingerprint sensing has been described above and thus will be omitted.

When the hidden page display unit 140 matches the fingerprint sensed by the fingerprint sensor unit 110 and the pre-registered fingerprint, as shown in FIG. 11C, the hidden page display unit 140 corresponds to the pre-registered fingerprint. Can be displayed.

The hidden page display unit 140 is a component for displaying the hidden page 111 and may be included in the screen display unit 130 shown in FIG. 3, but is not limited thereto. The hidden page display unit 140 may include a screen display unit ( 130 may be substituted.

The displayed hidden page 111 may function the same as the basic page 105.

On the other hand, even when the symbol 112 of the hidden page 111 is not displayed, when the display request of the hidden page 111 is made, when the hidden page 111 is generated, the fingerprint input request window 121 is displayed. Since it is displayed, the existence of the hidden page 111 can be known.

Meanwhile, the user terminal 100 may further include a hidden command input unit 150 and a hidden page hiding unit 160.

The hidden command input unit 150 may receive an input of a hidden command of the displayed hidden page 111.

In addition, the hidden page hiding unit 160 may hide the displayed hidden page 111 when the hidden command of the hidden page 111 is input through the hidden command input unit 150.

Through this, a user may hide or hide an important application 117 or the like in the hidden page 111, and the hidden hidden page 111 may not be displayed unless there is authentication of a true user through a fingerprint. The privacy function of the user can be further improved.

The hidden command of the hidden page 111 may be input in various ways, and is not limited to any particular method. For example, the user may touch the basic page 105 in a specific manner, press the fingerprint sensor 110, or input a fingerprint.

As shown in FIG. 12, upon creation of a hidden page, a hidden page is generated (S1201).

The hidden page generated in this way may not be displayed from the time of initial creation, or may not be displayed after being displayed for a predetermined time at the time of initial creation, or may be set to continue to be displayed from the time of initial creation. It may be set to be selected by this user.

The hidden page may be generated separately from the default page provided by default, and one or more may be generated.

In addition, when the hidden page is generated, a symbol representing the hidden page may be displayed, and of course, may not be displayed.

After S1201, upon requesting the display of the hidden page, the fingerprint input request window is displayed (S1202).

In this case, the display request of the hidden page may be variously made. For example, the user may make a swipe gesture or touch a symbol of a hidden page while the user touches the screen to switch from the last basic page (that is, the next screen is displayed).

After S1202, the user's fingerprint can be sensed (S1203), and if the sensed fingerprint matches the pre-registered fingerprint, the hidden page is displayed (S1204).

Since the displayed hidden page can function the same as the main page, the user can store hidden applications or important applications or files in the hidden page.

After S1204, when the hidden page is input while the hidden page is displayed, the displayed hidden page may be hidden (S1205).

Here, the hidden command of the hidden page may be input in various ways, and is not limited to any particular method. For example, the user may touch the basic page in a specific manner, press the fingerprint sensor, or input a fingerprint.

As such, the hidden hidden page can be displayed only if the authentic user is authenticated through the sensed fingerprint, thereby further improving the privacy protection of the true user.
