  • Patent number: 10637851
    Abstract: A method for introducing an identity into a secure element includes an operating system loaded into the secure element, which comprises a master key which is identical for a plurality of secure elements. A secure-element key datum is generated employing the master key. The secure-element key datum is configured as a temporary secure-element key datum, which, upon an initial authentication of the secure element vis-à-vis the background system, is replaced by a final secure-element key datum which is independent of the master key by employing the temporary secure-element key datum and is itself rendered invalid for further authentications.

  • Publication number: 20180147881
    Abstract: An easily manufacturable multilayer security element has an opaque functional layer that is arranged between two build-up layers of transmissive material. The opaque functional layer has at least one cutout. The layers are connected by lamination to form an areal body with planar surfaces. The cutout is filled up with transmissive material of the build-up layers. One build-up layer supports a feature carrier layer. A security feature, which is arranged at least partially below the cutout, is formed in the feature carrier layer and/or between the functional layer and the feature carrier layer. The cutout forms an inner window through which the security feature is recognizable.

  • Publication number: 20170352298
    Abstract: A processor device has an executable implementation of a cryptographic algorithm implemented being white-box-masked by a function f. The implementation comprises an implemented computation step S by which input values x are mapped to output values s=S[x], and which is masked to a white-box-masked computation step T? by means of an invertible function f. As a mapping f there is provided a combination (f=(c1, c2, . . . )*A) of an affine mapping A having an entry width BA and a number of one or several invertible mappings c1, c2, . . . having an entry width Bc1, Bc2, . . . respectively, wherein BA=Bc1+Bc2+ . . . . Output values w are generated altogether by the mapping f. Multiplicities of sets Mxi, i=1, 2, . . . =Mx11, Mx12, . . . Mx21, Mx22, . . . are formed from the output values a of the affine mapping A.

  • Patent number: 9794773
    Abstract: A method for managing, e.g. subscriptions on a security element of, a mobile device comprises the steps of recognizing a new network and initiating a management step. In order to recognize the new network, information about a network selected by the mobile device is captured. Then, the captured information is evaluated in order to recognize the new network.

  • Patent number: 9718297
    Abstract: A security element for manufacturing value documents, such as banknotes, checks or the like, has an upper side making available several micro images, in particular for a lens magnification arrangement. Each micro image is formed by a micro cavity structure having a multitude of micro cavities disposed side by side, the micro cavities have an extension of 0.5 to 3 ?m respectively in a spatial direction disposed parallel to the upper side. The micro cavity structure is optically reflective or highly refractive on its surface, so that on the surface at least partial reflection takes place, and for each micro image micro cavities of at least a first and a second type are present, which differ by an aspect ratio of the micro cavities, whereby each micro image is structured by the at least two different types of micro cavities.

  • Patent number: 9703994
    Abstract: Checking of security elements for value documents, which have a plurality of magnetic regions, includes at least a high-coercivity magnetic region having a high-coercivity magnetic material, a low-coercivity magnetic region having a low-coercivity magnetic material, and, where applicable, a combined magnetic region containing both the high-coercivity and the low-coercivity magnetic material. After magnetization of all magnetic materials or the magnetic regions formed therefrom in one direction with a first magnetic field region, only the low-coercivity magnetic material is remagnetized in another direction in a subsequent second magnetic field region. Magnetic signals of the magnetic regions are captured while the security element is still subjected to the second magnetic field region. On the basis of the signals all three types of magnetic region can be reliably distinguished.

  • Patent number: 9690841
    Abstract: A method and apparatus for determining a class reference data record for classifying documents of value includes creating a class reference image using a multiplicity of reference images of already classified documents of value in the same class; and creating a class reference data record having at least one class reference parameter using the class reference image. The pixel and intensity values of the respective pixel in the class reference image are a function of the pixel values of the relevant pixels in the multiplicity of reference images of already classified documents of value in the same class. The method includes determining at least one quantitative property of a document of value to be classified; and classifying the document of value to be classified on the basis of a comparison between the quantitative property of the document of value to be classified and the class reference data record.

  • Patent number: 9685019
    Abstract: A method or apparatus for examining a security element of a value document involves at least one optical property of the security element influenceable by a magnetic field. The value document is transported through a magnetic field which is inhomogeneous transversely to the transport direction and/or is changed time-dependently. An image of at least one portion of the value document having the security element is captured and image data describing the image are formed. The optical properties of the security element are influenced by the magnetic field, and the image data is checked whether they have a location dependence transverse to the transport direction corresponding to the location dependence of the magnetic field and/or have a location dependence in the transport direction corresponding to the time dependence of the magnetic field.
