  • Patent number: 8255699
    Abstract: A portable data carrier (1) comprises an executable training module (8) which provides in a memory (4, 5) of the data carrier (1) a reference model (10; M) for the biometric recognition of a user of the data carrier (1) by a recognition module (9), whereby a biometric comparison vector (16) which lies within the acceptance range (A) of the reference model (10; M) is accepted by the recognition module (9) as coming from the user. In so doing, the training module (8) defines the reference model (10; M) by model nodes (P, P0-P4) which are formed from biometric reference vectors (17; N) in each case coming from the user, whereby a new model node (P, P0-P4) is added to the reference model (10; M) when the associated reference vector (17; N) lies outside the acceptance range (A) of the reference model (10; M).

  • Patent number: 8251365
    Abstract: The invention relates to a device and a method for monitoring the separation of a sheet product, particularly of banknotes. The invention is based on a device and a method for monitoring the separation of a sheet product, particularly of banknotes, by means of a separator (1, 2, 3) having a drive (4, 7) and a controller (8) for monitoring and controlling the angular speed (w) of the separator, and is based on monitoring of the angular speed of the separator by the controller for changes and the determination of faulty separation, if the change of the angular speed is greater than a permitted deviation, or if the angular speed falls below a threshold value (S).

  • Patent number: 8239683
    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 (20) has a converter unit (29) which converts transaction data to be interpreted into pixel values and displays them on a monitor (6), an interface of its own for directly attaching an input unit (7) via which a user confirms displayed transaction data, as well as a crypto unit (31) for generating a signature for a record of confirmed transaction data. In a variant the confirmation can be effected by the crypto unit (31) generating and displaying a random number which has to be inputted by the user via a conventionally attached input unit (14).

  • Publication number: 20120160632
    Abstract: The invention relates to a method and an apparatus for checking documents of value which have a security element with several magnetic areas, including at least one high-coercive magnetic area, at least one low-coercive magnetic area and at least one combined magnetic area which contains both the high-coercive and the low-coercive magnetic material. After the magnetization of all magnetic areas in a first direction, first magnetic signals of the security element are detected with a first magnetic detector. After a subsequent second magnetizing, which is effected antiparallel to the first magnetizing and magnetically reverses only the low-coercive magnetic material, second magnetic signals of the security element are detected. For identifying the magnetic areas, the second magnetic signals or a signal derived therefrom are compared with two thresholds.

  • Patent number: 8205249
    Abstract: A method for effecting a secure electronic transaction on a terminal using a portable data carrier is proposed. According to the method a user (30) first authenticates himself vis-à-vis the portable data carrier (20). The portable data carrier (20) at the same time produces quality information about how authentication was done. The authentication is confirmed to the terminal (14). Then the portable data carrier (20) performs a security-establishing operation within the transaction, for example the creation of a digital signature. It attaches the quality information to the result of the security-establishing operation.

  • Patent number: 8157102
    Abstract: The present invention relates to a method and apparatus for processing sheet material, in particular papers of value such as bank notes, checks, etc. The present invention starts out from the consideration that the validity of a successful check of sheet material is still present unchanged after an operating disturbance. The result of a check of sheet material which was performed successfully before a disturbance is therefore retained when a disturbance is present or after the disturbance has been eliminated.
