Method for distinguishing between a real face and a two-dimensional image of the face in a biometric recording process

摘要

The method involves dividing two recordings of a face into a number of image components, where each image component comprises a number of pixels. The displacement of the individual image components from one of the recordings to the other recording is determined by a correlation process. A displacement vector field is generated from the displacement of the image components. The displacement vector field is analyzed to determine whether the recordings are made of a real face or from a two-dimensional (2D) diagram of the face. An independent claim is also included for a method for identifying a person in a distributed information technology (IT)-infrastructure such as cloud environment.
