Abstract: An apparatus and method for the biometric identification of a person, who has an authentication area containing biometric features, the apparatus including a sensor having an identification area for detecting the biometric features of the part of the person's authentication area which is situated on the identification area, a comparison device for comparing the detected biometric features with the biometric features, stored in a memory, of a part of the authentication area of an authorized person or of a number of authorized persons in order to determine the relative position of the biometric features detected by the sensor within the part of the authentication area, and a computation device for calculating an identification code, which identifies the person detected by the sensor, from the detected biometric features which are not stored in the memory on the basis of the relative position of the biometric features which are stored in the memory within the stored authentication area.

Abstract: In order to determine the error rate of a biometric device, a number of foreign characteristic sets are stored in a database, which are compared during a testing process with the characteristic set of the authorized person, and personal error rates are determined for the authorized person based on this comparison.

Abstract: An apparatus and a method for extracting physiological data from the skin of a body, wherein the apparatus includes at least one fingerprint sensor for ascertaining a blackening profile and a pressure sensor for measuring a pressure profile for a pressure exerted on the fingerprint sensor.

Abstract: The invention relates to a scroll mouse comprising two mouse buttons (M1, M2). Between the two mouse buttons (M1, M2), a fingerprint line sensor (ZS) is disposed that can be used to identify a user and to detect the scroll-movement of the finger of a user.

Abstract: A system and method for evaluating a biometric detection system, in accordance with the present invention, provides an edited database including a plurality of existing biometric images with corrected extracted features that were acquired with a sensor or sensors different from the sensor of the system under evaluation. A second database, smaller than the edited database, is edited which includes biometric images (that were acquired by the sensor of the system under evaluation) are employed to evaluate the biometric detection system. The second database has errors in extracted features corrected. A statistical perturbation model is constructed to describe degradation characteristics of the extracted features from the second database as provided in the editing step. The statistical perturbation model is applied to the edited database to construct a perturbed database sensitive to degradations of the biometric system under evaluation.

Abstract: The invention is based on a transceiver for which two different off-states are provided. The user authentication module is not supplied with power in a first off-state whereas it is already supplied with power in a second off-state.

Abstract: The present invention relates to a method for checking access authorization for a system. A modified code is stored in the system in advance. An access authorization code is stored in a part of the system which users cannot access or have difficulty accessing. The modified code is different from the access code. Biological features of a user are detected and are compared with features that are stored in the system. If the features match, a computation rule is used to calculate a code from the modified code, the calculated code is transmitted to the part of the system which users cannot access, and there, it is checked using the stored access authorization code. The invention also relates to an apparatus for checking access authorization for a system.

Abstract: A video signal receiver has a first output terminal, at which only a chroma, video, blanking, sync signal or a video, blanking, syncs signal with a chrominance signal is output. A second output terminal carries the RGB color signals and the associated sync signals. Video recorders normally evaluate only a video, blanking, sync signal with the corresponding chrominance information and can be connected to the first output terminal. Television displays normally evaluate RGB signals as well and can be connected to the second output terminal. The signal output at the first output terminal for the video recorder can be selectively blocked by a control device which is controlled by an identifier produced at the transmitter end. As a result, it is possible to display an encrypted transmission on the television set, but not to record the transmission on the video recorder.

Abstract: Addressable first units having ROM memory cells, for example word or bit lines, can be replaced by redundant second units having RAM memory cells. This has the advantage that the RAM memory cells can be realized with a smaller area than alternative PROM memory cells. The invention can be applied particularly advantageously to DROM memories.

Abstract: A method and a circuit configuration for flicker reduction in a television set include counting the number of partial areas of a field/frame which have been ascertained to be moving, through the use of a motion detector. When a threshold value is exceeded, a changeover is made from a field reproduction sequence with reduced flicker to a field reproduction sequence with reduced flicker and correct motion. The method can be practiced by using standard components.
