  • Patent number: 10800201
    Abstract: A security object has a document body. A lens array is formed on a top side and first information is stored in the document body. The optical detectability of the first information through the lens array is dependent on a detection direction. The document body has a top view section, in which the document body has a material layer that is translucent or opaque, and adjacent thereto a window section, in which the document body is formed of a material transparent in volume between a top side and a bottom side. The lens array extends over part of the window section and over part of the top view section and spans a section boundary between the sections. The first information also is formed partially in the top view section and partially in the window section and, in the window section, laser-marked, static second information is stored in the document body.

  • Patent number: 10572638
    Abstract: A mobile terminal is provided by an issuing authority for capturing biometric data of a user for transmission to a security document. The mobile terminal includes a data storage unit containing a credential, an authentication module, a sensor for capturing the biometric data of the user and a control unit that is configured to capture the biometric data of the user only upon successful reciprocal authentication of the user and the mobile terminal. An authenticity test module tests the authenticity of the captured biometric data captured. If authentic, the captured biometric data is stored in the data storage unit in protected form. Readout of the biometric data from the mobile terminal, by an operator of the issuing authority, is permitted only if the operator has been authenticated to the mobile terminal using additional authentication data.
