Abstract
An adaptive spoofing method includes obtaining multiple images of a spoof representation of a human user. The multiple images are captured automatically by an image capture device, and each of the multiple images is captured at a different relative position between the image capture device and the spoof representation. The method also includes: executing a biometric authentication process separately on each of at least a subset of the multiple images; determining that the biometric authentication process authenticates the human user based on at least a first image from the subset; and identifying a relative position between the image capture device and the spoof representation corresponding to the first image as a failure condition associated with the biometric authentication process.
