The present invention improves the accuracy of determining a counterfeit living body. A biometric authentication device has a detection unit for detecting a region where moire is generated and a region relating to biometric information from imaged image data, and a determination unit for determining, on the basis of the region where moire is generated and the region relating to biometric information, whether or not the biometric information included in the image data is derived from imaging of a counterfeit living body.
