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: Certain embodiments provide a biometric recognition apparatus and a method for lowering false recognition rate of biometric information in an electronic device adopting biometric recognition technology. In doing so, the electronic device may store first feature values extracted at M-ary feature points from owner biometric information, and additionally store auxiliary biometric information from a biometric information stored in one or more memories or an external server. The electronic device may perform biometric recognition on input biometric information using the first feature values and second feature values extracted from the biometric information additionally stored.
