Abstract: Provided is a liveness verification method and device. A liveness verification device acquires a first image and a second image, and select one or more liveness models based on respective analyses of the first image and the second image, including analyses based on an object part being detected in the first image and/or the second image, and to verify, using the selected one or more liveness models, a liveness of the object based on the first image and/or the second image. The first image may be a color image and the second image may be an Infrared image.

Abstract: Disclosed is an electronic apparatus including a first camera, a second camera, and a processor. The first camera includes a first FOV. The second camera includes a second FOV corresponding to part of the first FOV. The processor is configured to obtain a request associated with biometric authentication. The processor is configured obtain at least one first image using the first camera and at least one second image using the second camera. The processor is configured to identify a first external object that is included in the at least first image while obtaining the first image. While obtaining the at least one second image, the processor is configured to provide notification information for obtaining at least one image including the second external object when the second external object that is at least part of the first external object, is not included in the at least second image.
