The present invention can execute different applications depending on whether a smart band is worn when a touch is detected. Here, different applications include different versions of the currently displayed screen.

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

Referring to FIG. 5, each device can detect not only the user's touch on the screen but also a smart band in the vicinity as described above (S200).

Once the user touch is detected, the control unit determines whether the touch is the touch by the hand wearing the smart band (S210). The determination may be performed through transmission of biometric information through short-range communication or may be performed through a camera image.

According to the determination result, the controller applies different scenarios to different operations, i.e., the currently displayed screen. For example, if the sensed touch is a touch by a hand wearing a smart band (S220), the first scenario is applied. Otherwise, the second scenario is applied (S230).

Preferably, the first scenario may be an application for an authorized user, and the second scenario may be an application for a restricted user.

On the other hand, if the gallery menu is touched (selected) by a hand that does not wear the smart band, the control unit recognizes that the access authority is limited and displays only some pictures for privacy protection.

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

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

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

As shown in FIG. 6A, when the biometric information icon 60 is touched on the predetermined payment screen, the controller of the device performs different operations depending on whether or not the user wore the smart band. That is, if the user touches the icon 60 while wearing the smart band, the control unit automatically inputs the ID and password of the user to the information input window to perform online settlement, and displays the settlement completion pop-up 61 do. On the other hand, if the user touches the icon 60 without wearing the smart band, the control unit displays a popup (not shown) including a message to input biometric information.

6B, when the user touches the information input window of the login screen displayed on the current device with the other hand while the user holds the device (eg, smartphone) with one hand, Different operations are performed depending on whether or not the band is worn. That is, when the user touches the information input window with the smart band worn, the control unit automatically inputs the ID and password of the user to the information input window and performs login. On the other hand, if an information input window is touched while the smart band is not worn, the control unit displays a key arrangement for inputting a user ID and a password.

Therefore, according to the present invention, it is possible to maintain security by outputting different versions of the same application or screen according to whether or not the smart band is worn, or by changing the application and displaying the same. In addition, Or perform an operation.

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

As shown in FIG. 7, when the smart band approaches the controller of the device, the device performs user authentication using the biometric information provided in the smart band (S300, S310). If the user authentication is successful, the control unit confirms the emotion information of the user (S320). The emotion information may be transmitted together with the biometric information from the smart band, or may be received from the smart band upon request of the device. The emotion information can be determined by comparing information such as heart rate, body temperature, and blood pressure with reference information as information such as normal, sadness, and anger in addition to the scoring index.

When the emotion information is confirmed, the control unit executes different applications on the initial screen according to the type of the determined emotion information. For example, if the user is in a normal state, an initial menu screen may be displayed, and in a sad state, a music playback screen may be displayed. Further, the stress management application can be executed when the user is in an anger state or a stress state.

Accordingly, the present invention can provide convenience to the user by automatically executing the application according to the emotional state of the user after performing the 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. Such an authentication method can be utilized for financial settlement which has a strong security strength.

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