  • Device for controlling an actuator
    Patent number: 8482377
    Abstract: An apparatus includes an energy store for supplying an actuator, an antenna device for receiving, by contactless communication, energy for charging the energy store and one or more control signals comprising a command for triggering the actuator, and a control unit for controlling the supply of energy to the actuator on the basis of the control signals. After the triggering command has been received, the state of charge of the energy store is determined. When this state is less than a state of charge threshold value that is sufficient for triggering the actuator, a response signal to continue contactless communication is transmitted to the transmitting device via the antenna device. When this state is greater than or equal to the state of charge threshold value, the control unit controls the supply of energy from the energy store to the actuator so that it is possible to trigger the actuator.

  • PORTABLE DATA CARRIER HAVING AN OPERATING ERROR COUNTER
    Publication number: 20130174283
    Abstract: A method in a portable data carrier for safeguarding the data carrier against external attacks on the data carrier, wherein at least one counter is employed in the data carrier. A specified command is safeguarded such that it is executed by the data carrier only when the at least one counter lies in a specified values range. The at least one counter is decremented before an execution of the command and incremented only when the command has been executed without interruption. The at least one counter here is settable multiple times, in particular even after the issuance of the data carrier to a user.

  • METHOD FOR CHECKING AN OPTICAL SECURITY FEATURE OF A VALUE DOCUMENT
    Publication number: 20130170747
    Abstract: A method for checking a prescribed optical security feature on a prescribed portion of a value document based on pixel data of pixels of an image of the portion which are associated with places on the portion and render optical properties of the value document at the places. A check is made of whether a first number of those pixels whose pixel data, according to a first prescribed criterion, lie within a first reference region prescribed for the security feature exceeds a first minimum hit value prescribed for the security feature, and whether a first scatter of the pixel data of the pixels exceeds a first minimum scatter value prescribed for the security feature. An authenticity signal is formed which represents an indication of authenticity only when the first number exceeds the first minimum hit value, and the scatter the first minimum scatter value.

  • PORTABLE DATA CARRIER AS A WEB SERVER
    Publication number: 20130166685
    Abstract: The invention relates to a method for providing hypertext data through a hypertext server on a portable data carrier for a terminal connected to the portable data carrier, and to an accordingly adapted portable data carrier. The hypertext server receives a hypertext query of the terminal and thereupon provides hypertext data relating to the hypertext query. The hypertext server then sends the provided hypertext data as a hypertext response to the terminal. The method is characterized in that upon the providing of the hypertext data at least one hyperlink contained in the hypertext data is checked and the checked hyperlink is contained in the hypertext response.

  • SECURITY FEATURE
    Publication number: 20130106090
    Abstract: The invention relates to a security feature with a luminescent pigment which has a host lattice doped with a luminophore and which is optically excitable to emit luminescent light. The luminescent light of the luminescent pigment has a luminescence spectrum with a first luminescence peak and a second luminescence peak whose peak intensities respectively depend on an amount fraction x of the luminophore in the luminescent pigment. In the luminescent pigment according to the invention, the host lattice and the luminophore and the amount fraction x of the luminophore are chosen such that even a slight increase or reduction of the amount fraction x of the luminophore causes a strong relative change of the peak intensities IA and IB. This increases the forgery-proofness of the luminescent pigment according to the invention.

    Abstract: In a method for the personalization of portable data carriers into a non-volatile memory of the data carrier there are written personalization data, wherein the personalization at first is carried out as a virtual personalization in a virtual data carrier, then a memory image is generated as a bit-true image of a memory of the virtual data carrier and finally the memory image with the aid of its physical memory addresses is directly introduced into the memory of the real data carrier. Here the personalization data in addition to the initialization data also comprise individualization data. Preferably, the introduction of the personalization data into the data carrier can be carried out after the production of the data carrier at an authority issuing the data carrier or at the end user.

  • Method for individualising security documents and corresponding security document
    Patent number: 8418615
    Abstract: A method for individualizing security documents provides that high security quality, application-neutral printed image 1 identical for a group of security documents is overprinted with second printed image 2 individualizing the security document, whereby the printing ink of second printed image 2 is repelled by the printing ink of first printed image 1. The printing ink of the second printed image is therefore deposited only in the areas of the first printed image where no printing ink of the first printed image is present. Preferably, the first printed image is produced by intaglio printing and the second printed image by means of liquid printing ink, in particular by the ink jet method.

  • Initialization of a chip card
    Patent number: 8423797
    Abstract: In a method for reading initialization data (IND) into a chip card, the chip card receives an encrypted authentication value (EAV) and decrypts it to obtain at least one release key (ENK). The release key (ENK) is checked for a match with a release key (ENK?) stored on the chip card (14). If there is a match, the initialization data (EIND, IND) are received and written to a nonvolatile memory of the chip card. A method for generating a record for initializing a chip card. a chip card and a computer-readable data carrier have corresponding features. The invention is provided in particular for initialization of chip cards by external partners of the chip card manufacturer, whereby as few possibilities of attack as possible are to be offered.
