Abstract

A device and a method for authenticating using biometric information in an electronic device are provided. The electronic device includes a display, and at least one processor. The at least one processor detects an execution of an application which provides an authentication service based on biometric information, changes at least one biometric information recognition related variable, in response to detecting the execution of the application, and controls to display an application execution screen including at least one authentication guide image corresponding to the at least one biometric information recognition related variable. Other embodiments may also be possible.

First claim

What is claimed is:

1 . An electronic device comprising:
a display; and at least one processor configured to:
detect an execution of an application which provides an authentication service based on biometric information,
change at least one biometric information recognition related variable, in response to detecting the execution of the application, and
control the display to display an application execution screen including at least one authentication guide image corresponding to the at least one biometric information recognition related variable.

2 . The electronic device of claim 1 , further comprising:
a camera configured to obtain a captured image including the biometric information, wherein the at least one biometric information recognition related variable includes at least one of a variable indicating a state of a reference area which is set for recognizing the biometric information from the captured image, or a variable indicating a state of the captured image.

3 . The electronic device of claim 2 , wherein the at least one biometric information recognition related variable includes at least one of a position of the reference area, an angle of the reference area, a size of the reference area, a position of the captured image, an angle of the captured image, or a size of the captured image.

4 . The electronic device of claim 2 , wherein the at least one authentication guide image includes at least one of a first authentication guide image corresponding to the reference area, or a second authentication guide image corresponding to the captured image.

5 . The electronic device of claim 1 , wherein the at least one processor is further configured to control, based on a value obtained by a change of the at least one biometric information recognition related variable, a display of the at least one authentication guide image.

6 . The electronic device of claim 1 ,
wherein the at least one processor is further configured to change the at least one biometric information recognition related variable from a predetermined first value to a second value, in response to detecting the execution of the application, and wherein the second value is a random value or a value determined according to a predetermined regulation.

7 . The electronic device of claim 1 ,
wherein the display comprises a touch sense display configured to detect a user input, and wherein the at least one processor is further configured to:
detect a user input for the at least one authentication guide image,
update, based on the user input, a display of the at least one authentication guide image, and
update, based on the user input, the at least one biometric information recognition related variable.

8 . The electronic device of claim 1 ,
wherein the display includes a touch sense display configured to detect a user input, wherein the application execution screen includes at least one notification information related to the application, and wherein the at least one processor is further configured to:
detect a user input for the notification information, and
restore the at least one biometric information recognition related variable into an original value, in response to the user input.

9 . The electronic device of claim 1 , wherein the at least one processor is further configured to perform, based on the at least one biometric information recognition related variable, a user authentication.

10 . A method of operating an electronic device, the method comprising:
detecting an execution of an application which provides an authentication service based on biometric information; changing at least one biometric information recognition related variable, in response to detecting the execution of the application; and displaying an application execution screen including at least one authentication guide image corresponding to the at least one biometric information recognition related variable.

11 . The method of claim 10 , further comprising:
obtaining a captured image including the biometric information, wherein the at least one biometric information recognition related variable includes at least one of a variable indicating a state of a reference area which is set for recognizing the biometric information from the captured image, or a variable indicating a state of the captured image.

12 . The method of claim 11 , wherein the at least one biometric information recognition related variable includes at least one of a position of the reference area, an angle of the reference area, a size of the reference area, a position of the captured image, an angle of the captured image, or a size of the captured image.

13 . The method of claim 11 , wherein the at least one authentication guide image includes at least one of a first authentication guide image corresponding to the reference area, or a second authentication guide image corresponding to the captured image.

14 . The method of claim 10 , wherein the displaying the application execution screen comprises controlling, based on a value obtained by a change of the at least one biometric information recognition related variable, a display of the at least one authentication guide image.

15 . The method of claim 10 ,
wherein the changing the at least one biometric information recognition related variable comprises changing the at least one biometric information recognition related variable from a predetermined first value to a second value, in response to detecting the execution of the application, and wherein the second value is a random value or a value determined according to a predetermined regulation.

16 . The method of claim 10 , further comprising:
detecting a user input for the at least one authentication guide image; updating, based on the user input, a display of the at least one authentication guide image; and updating, based on the user input, the at least one biometric information recognition related variable.

17 . The method of claim 10 , further comprising:
detecting a user input for at least one piece of notification information included in the application execution screen; and restoring the at least one biometric information recognition related variable into an original value, in response to the user input.

18 . The method of claim 10 , further comprising:
performing, based on the at least one biometric information recognition related variable, a user authentication.

19 . An electronic device comprising:
a display; a camera; and at least one processor configured to:
obtain biometric information from an image input from the camera,
perform, based on the biometric information, a user authentication,
detect whether an event for performing an operation corresponding to a user authentication success occurs, and
perform a function corresponding to the user authentication success, in response to detecting the event.

20 . The electronic device of claim 19 , wherein the at least one processor is further configured to:
drive at least one sensor, in response to the success of the user authentication, and detect whether the event for performing the operation corresponding to the user authentication success occurs using the at least one driven sensor.
