3 is a flowchart illustrating a user authentication method using a smart band according to a first embodiment of the present invention.

3, the device receives the user's biometric information from the smart band when access to the smart band is detected (S100 to S120), and compares the received biometric information with previously registered biometric information to perform user authentication . The user authentication is performed in the background.

If the user authentication is successful, the control unit of the device provides an authentication service for the screen currently being displayed on the display unit (S140). The authentication service may include payment and login to a predetermined website or application.

4A to 4C are an example of a user authentication method using a smart band.

Referring to FIG. 4A , when the mobile terminal 100 is held with a hand on which the smart band 100 is worn on the wrist, biometric information is automatically transmitted from the smart band 100 to the mobile terminal 100 . The control unit 180 of the mobile terminal 100 performs user authentication by comparing it with biometric information stored in the memory 16, and when the user authentication is completed, the password is automatically applied to the lock screen 50 currently displayed on the display unit.

According to the present invention, different applications can be executed depending on whether the smart band is worn when touch is detected. Here, different applications include different versions of the currently displayed screen.

5 is a flowchart illustrating a user authentication method using a smart band according to a second embodiment of the present invention.

Referring to FIG. 5 , each device may detect not only a user touch on a screen but also a smart band that is adjacent as described above ( S200 ).

Once the user's touch is detected, the controller determines whether the corresponding touch is a touch by a hand wearing the smart band (S210). The determination may be performed through whether or not biometric information is transmitted through short-distance communication or may be performed through a camera image.

The controller applies different operations, that is, different scenarios to the currently displayed screen, according to the determination result. For example, if the sensed touch is a touch by a hand wearing the smart band (S220), the first scenario is applied, and if it is not a touch by the hand wearing the smart band, the second scenario is applied (S230).

Preferably, the first scenario may be an application for a user whose access right is permitted, and the second scenario may be an application for a user with limited access right.

For example, when the gallery menu is touched (selected) by the hand wearing the smart band, the controller recognizes that the access right is permitted and displays all photos in the album. On the other hand, when the gallery menu is touched (selected) by a hand not wearing the smart band, the controller recognizes that the access right is restricted and displays only some photos for privacy protection.

As another example, when the screen is touched (selected) by the hand wearing the smart band, the controller may recognize that the access right is permitted and display a dedicated background screen set by the user. On the other hand, when touched by a hand not wearing a smart band, a normal background screen (e.g., standby screen) is displayed.

Preferably, the first scenario may be a user-customized operation for the content displayed on the screen, and the second scenario may be a general operation of the content. The customized operation may include changing (enlarging or reducing) the size and shape of an application, content, text, etc. according to the age of the user.

6A and 6B are an example of a user authentication method using the smart band shown in FIG. 5 .

As shown in FIG. 6A , when the biometric information icon 60 is touched on a predetermined payment screen, the control unit of the device performs different operations depending on whether the user is wearing the smart band or not. That is, when the user touches the icon 60 while wearing the smart band, the control unit automatically enters the user's ID and password in the information input window to perform online payment and then displays the payment completion pop-up 61 do. On the other hand, when the icon 60 is touched while not wearing the smart band, the controller displays a pop-up (not shown) including a message to input biometric information.

In addition, as shown in FIG. 6B , when the user touches the information input window of the login screen currently displayed on the device with the other hand while holding the device (eg, a smartphone) with one hand, the control unit allows the user to use the smart phone. Different motions are performed depending on whether the band is worn or not. That is, when the user touches the information input window while wearing the smart band, the controller automatically inputs the user's ID and password into the information input window to log in. On the other hand, when the information input window is touched while not wearing the smart band, the control unit displays a key arrangement for inputting the user's ID and password.

Therefore, according to the present invention, it is possible to maintain security by outputting different versions of the same application or screen or changing and displaying the application depending on whether the smart band is worn or not, as well as conveniently desired applications without separately performing information input menu selection. can be executed or an action can be performed.

7 is a flowchart illustrating a user authentication method using a smart band according to a third embodiment of the present invention.

In the present invention, after authenticating a user using biometric information transmitted from a smart band, a separate scenario can be applied according to emotional information (normal, sad, anger, and stress).

As shown in FIG. 7 , when the smart band approaches, the device controller performs user authentication using biometric information provided from the smart band (S300, S310). If the user authentication is successful, the control unit checks the user's emotion information (S320). The emotion information may be transmitted together with biometric information from the smart band, or may be received from the smart band according to a device request. The emotional information may be determined by comparing information such as heart rate, body temperature, and blood pressure with reference information as information such as normality, sadness and anger together with the stress index.

When the emotion information is confirmed, the controller executes different applications on the initial screen according to the type of the checked emotion information. For example, if the user is in a normal state, an initial menu screen may be displayed, and if the user is in a sad state, a music playback screen may be displayed. Also, when the user is in an angry or stressed state, the stress management application may be executed.

Accordingly, the present invention can provide convenience to the user by automatically executing an application according to the user's emotional state after performing user authentication using the smart band.

The present invention can perform multi-factor authentication by combining information such as voice and personal identification number (PIN) as well as biometric information. This authentication method can be used for financial settlements with very strong security strength.

8A and 8B are an example of performing multi-factor authentication according to an embodiment of the present invention.

As shown in Fig. 8a, in one embodiment, the device performs primary authentication using biometric information transmitted from the smart band in the case of financial payment, and provides a voice input option when the primary authentication is successful to use the user's voice Thus, secondary authentication can be performed.

In addition, as shown in FIG. 8b, the device performs primary authentication using biometric information transmitted from the smart band in the case of financial payment, and displays a personal identification number (PIN) input window when the primary authentication succeeds. Secondary authentication can also be performed using a personal identification number (PIN).

As described above, the present invention performs user authentication using biometric information measured by a smart band worn on the wrist, and performs authentication more conveniently by applying different scenarios depending on whether or not the smart band is worn when a touch is sensed. Not only can it be done, but it also has the advantage of providing a user-customized authentication service.
