The processor is configured to obtain a request associated with biometric authentication, obtain an image including at least one external object using the camera, display a specified image on the display, when displaying at least a portion of the obtained image on a specified area of the display, the at least a portion of the obtained image being as a portion of the specified image, in response to displaying a specified object associated with the biometric authentication among the at least one external object on the specified area, perform the biometric authentication using biometric information corresponding to the specific object, and when displaying another image different from the obtained image on the display, the other image being as a portion of the specified image, in response to obtaining an image including the specified object among the at least one external object, perform the biometric authentication using the biometric information corresponding to the specified object. In addition, various embodiments recognized through the specification are possible. ## Claims ### Claim 1 An electronic device, comprising: a camera; a display; and a processor, wherein the processor is configured to: obtain a request associated with biometric authentication; obtain an image including at least one external object using the camera, in response to the request, wherein the image comprises a specified area and a non-specified area; identify a state of the electronic device; when the state of the electronic device corresponds to a first state: display a preview image comprising the specified area of the display in conjunction with the biometric authentication; and in response to identifying that the specified area of the image includes a specified biometric object associated with the biometric authentication among the at least one external object, perform the biometric authentication using biometric information corresponding to the specific biometric object; and when the state of the electronic device corresponds to a second state: display a non-preview image on the display; and in response to identifying that the image includes the specified biometric object among the at least one external object, perform the biometric authentication using the biometric information corresponding to the specified biometric object, wherein the first state is a state where the biometric authentication is used to perform payment, and wherein the second state is a state where the biometric authentication is used to unlock the electronic device. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the processor is configured to: display the at least a portion of the obtained image on the specified area; and withhold the biometric authentication when the at least a portion of the image does not include the specified biometric object. ### Claim 3 (depends on 1) The electronic device of claim 1, wherein the processor is configured to: recognize the specified biometric object in the at least a portion of the obtained image. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein the specified biometric object includes at least one of an iris or a face. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the processor is configured to: recognize the specified biometric object in the at least a portion of the obtained image and an area other than the at least a portion of the obtained image, while displaying the non-preview image on the display. ### Claim 6 (depends on 2) The electronic device of claim 2, wherein the processor is configured to: display a guide associated with the specified area on the display. ### Claim 7 (depends on 1) The electronic device of claim 1, wherein the processor is configured to: determine an authentication area for obtaining the specified biometric object based at least on the image displayed on the specified area. ### Claim 8 (depends on 7) The electronic device of claim 7, wherein the processor is configured to: set a first area corresponding to the specified area to the authentication area, when displaying the at least a portion of the obtained image; and set a second area wider than the first area to the authentication area, when displaying the non-preview image. ### Claim 9 (depends on 8) The electronic device of claim 8, wherein the second area corresponds to an entire area of the obtained image. ### Claim 10 (depends on 7) The electronic device of claim 7, wherein the non-preview image includes an image displayed on the display before obtaining the image. ### Claim 11 A method, comprising: obtaining a request associated with biometric authentication; obtaining an image including at least one external object using a camera, in response to the request, wherein the image comprises a specified area and a non-specified area; identifying a state of an electronic device; when the state of the electronic device corresponds to a first state: displaying a preview image comprising the specified area of a display in conjunction with the biometric authentication; and in response to identifying that the specified area of the image includes a specified biometric object associated with the biometric authentication among the at least one external object, performing the biometric authentication using biometric information corresponding to the specified biometric object; and when the state of the electronic device corresponds to a second state: displaying a non-preview image on the display; and in response to identifying that the image includes the specified biometric object among the at least one external object, performing the biometric authentication using the biometric information corresponding to the specified biometric object, wherein the first state is a state where the biometric authentication is used to perform payment, and wherein the second state is a state where the biometric authentication is used to unlock the electronic device. ### Claim 12 (depends on 11) The method of claim 11, further comprising: displaying the at least a portion of the obtained image on the specified area; and withholding the biometric authentication, when the at least a portion of the image does not include the specified biometric object. ### Claim 13 (depends on 12) The method of claim 12, further comprising: displaying the at least a portion of the obtained image on the specified area; and displaying a guide associated with the specified area on the display, when the at least a portion of the obtained image does not include the specified biometric object. ### Claim 14 (depends on 11) The method of claim 11, further comprising: recognizing the specified biometric object in the at least a portion of the obtained image, when displaying the at least a portion of the obtained image on the specified area of the display. ### Claim 15 (depends on 11) The method of claim 11, further comprising: determining an authentication area for obtaining the specified biometric object based at least on the image displayed on the specified area.
