Mobile terminal, smart watch, and method of performing authentication with the mobile terminal and the smart watch
The present invention relates to a mobile terminal and a method capable of performing authentication using a smart watch, including: detecting a request for authentication for executing an application; measuring a user's heartbeat rhythm through a sensor mounted in a bottom of the smart watch when detecting the request for the authentication; and comparing the measured heartbeat rhythm with an already-stored heartbeat rhythm and thus performing the authentication on the application.
1. A smart watch comprising:
a display unit;
a sensor mounted in a bottom of a smart watch; and
a controller configured to:
measure a heartbeat rhythm using the sensor when an authentication request signal for an application displayed on an external apparatus is detected, wherein the external apparatus is interworked with the smart watch,
perform an authentication for the application by comparing the measured heartbeat rhythm with a stored heartbeat rhythm, and
transmit a result of the authentication to the external apparatus so that the external apparatus can execute the application,
wherein the external apparatus is further configured to:
detect a grip type in which a user holds a mobile terminal in one hand or both hands,
automatically measure the heartbeat rhythm using the sensor when a stored specific grip type is detected,
perform a user authentication by comparing the measured heartbeat rhythm with a stored heartbeat rhythm, and
display a function screen that is frequently used in the detected specific grip type when the authentication is completed,
wherein the function screen includes at least one a website, a game site, a bank website, and a cloud image folder, and
wherein the controller is further configured to:
execute a different operational mode according to the detected specific grip type and which finger touches on the mobile terminal.
2. The smart watch of claim 1 , wherein the authentication request signal is input into the smart watch or is received from the external apparatus.
3. The smart watch of claim 1 , wherein the authentication request signal is generated when user authentication is selected from an authentication screen, and
wherein the authentication screen is a screen for inputting a personal information of a user, and includes a payment screen of an on-line banking site or an on-line shopping mall, a web page, a logging-on screen of an application or a messenger and a locked screen.
4. The smart watch of claim 3 , wherein the personal information includes at least one among an authentication certificate, a password, a credit card number, an account number, and ID.
5. The smart watch of claim 1 , wherein the controller displays the result of the authentication on a screen of the smart watch,
wherein the external apparatus transmits the authentication request signal, along with information necessary for the authentication, and
wherein the information necessary for the authentication includes payment information or money transfer information.
6. The smart watch of claim 1 , wherein the external apparatus controls operation of the application according to a gesture that is made using a user's hand on which the smart watch is worn.
7. The smart watch of claim 6 , wherein the external apparatus displays a fan-shaped menu for functionality items that can be performed between the smart watch and the external apparatus when the user's hand on which the smart watch is worn is moved in a predetermined direction while being opened.
8. The smart watch of claim 7 , wherein the fan-shaped menu is displayed on a wallpaper screen or a predetermined website, and includes functionality items including authentication and payment, a web browser, a messenger, and a frequently-used program.
9. The smart watch of claim 7 , wherein a functionality item associated with the application is in focus on the fan-shaped menu.
10. The smart watch of claim 6 , wherein the external apparatus includes at least one or more sensors that senses the heartbeat rhythm, and
wherein the sensors are positioned in a specific portion, through the screen or through the external apparatus.
11. The smart watch of claim 10 , wherein the specific portion includes at least one, among a front side, a rear side, an upper end, and a lower end, and a bezel of the external apparatus, and is changed depending on a shape of the external apparatus and on a grip type.
