  • Publication number: 20180012059
    Abstract: The invention presents a process for determining a video as being a spoof or a genuine recording of a live biometric characteristic, characterized in that it comprises the steps of: preprocessing (200) the video, determining a liveness score (300) of the video, said determination comprising, for each frame of a plurality of frames (j) of the video: computing a difference between a motion intensity of a current frame and that of each frame of a set of preceding frames to infer a differential motion intensity of the current frame, inferring (330), from the differential motion intensities of the plurality of frames, a motion intensity of the video, comparing (340) said motion intensity to a predetermined threshold, and assigning a liveness score to the video, and determining (400) whether the video is a genuine recording of a biometric characteristic or a spoof.

  • Publication number: 20160269178
    Abstract: Generating a distinguishing feature vector by means of a distinguishing feature extractor module from a raw biometric feature of the individual, the distinguishing feature vector being configured for differentiating individuals is carried out in a method. Further steps include generating a robust feature vector by means of a robust feature extractor module from the raw biometric feature of the individual; generating a cryptographic key from first auxiliary data based on the secret of the individual and optionally other data; using the robust feature vector together with second auxiliary data in a standard cryptographic module configured to perform a standard cryptographic function keyed by the cryptographic key; and binding the results produced by the standard cryptographic module and the distinguishing feature vector together as fused data by means of a modulo-N addition operation module, wherein N=2, 3, . . . , i.e. N is an integer greater than 1.

  • Publication number: 20160230805
    Abstract: A shaft of a turbine engine made from fiber-composite material, having a sinusoidal inner profile which extends over the entire length of the shaft on its inner wall, where a first inner layer forms the sinusoidal inner profile and has fibers arranged at ±45° relative to the axial direction, where the concave outer areas of the first layer are filled with fibers parallel to the center axis by a second layer to form a cylindrical outer contour. The second layer extends in the circumferential direction only in the concave area. A third layer with fibers arranged at ±30° relative to the axial direction is provided on the second layer A fourth layer with fibers arranged at ±88° relative to the axial direction is provided on the third layer. An intermediate layer is formed between the second and third layers from fibers parallel to the axial direction.

  • Patent number: 8788837
    Abstract: A method for transmitting data confirmed by at least one person (KND), wherein data (TOR) to be transmitted are received and/or generated by an input device (BSW), wherein the input device (BSW) can be operated by the person (KND). A configuration for performing the method and a computer program for implementing the steps are also provided.

  • Publication number: 20030116627
    Abstract: The present invention relates to a method for integrating hidden information in a set of notes. In this method, the geometric shape of the geometric elements of the set of notes and/or their geometric relationship to each other are modified compared to the original version according to a predetermined key in such a manner that the modifications bear the to-be-integrated information in digital form and legibility of the set of notes is not impaired.
