Abstract: A method for managing issuance of a portable data carrier using multiple production units for issuing portable data carriers, a data provisioning unit and an assignment unit. The data provisioning unit receives data for the portable data carrier in a production unit independent format. At least one production unit is assigned to use the data for issuing the portable data carrier in the assignment unit. The data are provided by the data provisioning unit to the assigned production unit and the portable data carrier is issued in the assigned production unit. The data are provided by the data provisioning unit to the assigned production unit in response to a data independent polling for data by the assigned production unit and in the production unit independent format. In the assigned production unit the provided data are converted from the production unit independent format into a production unit dependent format.

Abstract: A method and system for challenge-response authentication are provided. Challenge data are transferred within an anti-collision loop from a reading device to a transponder by means of one or more commands of an anti-collision method, with the one or more commands serving to determine transponder identification data. In the one or more commands respective challenge data are contained in a data field that is used for specifying transponder identification data, wherein it is indicated to the transponder by a parameter value in the at least one of the one or more commands that the data field of the one or more commands contains challenge data instead of transponder date. The transponder recognizes with the help of the parameter value that in the received one or more commands challenge data are contained. The transponder processes the transferred challenge data based on the challenge response authentication.

Abstract: The invention relates to a method for performing machine checking of electronically-stored personal data in a passport booklet. The data are transmitted in an obscured form to a reader device after the passport has been presented to this reader device, and the accuracy of the obscuring is first verified and the obscuring is then removed. A positive signal is issued in the event of a successful verification. The recovered personal data are subsequently checked for authenticity. The verification and removal of the obscuring, as well as the authenticity check, ensue in a time-staggered manner after the passport booklet has been removed from the reader device by a verifying person in order to conduct further checks.

Abstract: A method for monitoring transport of bank notes in a transport system, using sensors arranged along the transport system for sensing transported bank notes, and a control device for monitoring and controlling the transport system using signals from the sensors, from which the control device derives a presence or absence of a bank note at the location of the respective sensor. The signals from all sensors are stored in a memory, and the signals from all sensors are assigned an explicit time statement or clock statement. All transported bank notes are assigned an explicit object code by the control device, and the object code is linked to the explicit time statement or clock statement. Stored signals from the sensors derive the occurrence and type of errors during the transport of the bank notes, and the signals are linked to the bank notes denoted by the object codes.

Abstract: A method for securely storing data in a multilevel memory of a portable data carrier. The multilevel memory includes one or several multilevel memory cells (SZ) which can assume respectively at least three levels (E, NE). The at least three levels represent a different data content, regarding which respective levels (E, NE) of a memory cell (SZ) are defined as valid or invalid. The levels (E, NE) of a respective memory cell (SZ) are selectively defined as valid or invalid in dependence on a required security level.

Abstract: The invention relates to a method and apparatus for recognizing forged value documents, for example composed forgeries which are assembled from parts of different value documents. In the inventive method, the signal intensity of a measuring signal is determined at a plurality of measuring points on a value document. For one or more selected groups of measuring points which are disposed in particular along certain directions on the value document there are determined gradient values of the signal intensities. The gradient values of a group are subsequently linked to form a connection strength of the group which provides a quantitative statement about the extent to which a large gradient value exists consistently within the particular group. From a relatively great connection strength there can be inferred the presence of a separating line in the area of the selected group of measuring points.

Abstract: The invention relates to a document of value, such as e.g. a bank note or the like, which has a security paper. In the security paper at least one tangible marking in the form of a relief structure is produced by a laser.

Abstract: A method and a display preparation unit are proposed for the execution of a transaction during which transaction data are processed which have to be confirmed by a user. The display preparation unit has a converter unit which converts transaction data to be interpreted into pixel values and displays them on a monitor, an interface of its own for directly attaching an input unit via which a user confirms displayed transaction data, as well as a crypto unit for generating a signature for a record of confirmed transaction data. In a variant the confirmation can be effected by the crypto unit generating and displaying a random number which has to be inputted by the user via a conventionally attached input unit.

Abstract: In a process for memory management in the execution of a program by a portable data carrier which has a first and a second memory region for the storage of objects generated in program execution, an object is initially created at least in part in the second memory region. If, in the course of further program execution, a persistent reference to the object is generated, the object is transferred to the first memory region. In a process for converting a source program into an executable program, a check is carried out at compile time as to whether a persistent reference to an object to be newly created is generated. Depending on the result of that check, program code is generated which creates the object either in the first or at least in part in the second memory region.

Abstract: A method and a data carrier for contactless communication of a reading device with at least two communication-ready applications located on a portable data carrier. A first communication-readiness signal is generated for a first application and sent to the reading device, the signal having a first identification number that is assigned to the first application and indicates to the reading device the communication readiness of said first application, and a second communication-readiness signal is generated and sent for a second application, the second signal having a second identification number different from the first identification number, which is assigned to said second application and indicates to the reading device the communication readiness of the second application. The identification numbers simulate for the reading device the communication readiness of a data carrier in each case. The reading device thus has the impression of communicating with applications of two separate data carriers.
