Arrangement and method for identifying fingerprints
First Claim
1. An arrangement for identifying fingerprints, comprising:
- at least one fingerprint sensor to detect at least one fingerprint;
at least two electrodes; and
a controller to apply and evaluate at least one electrical signal between the two electrodes,wherein a first electrode is spaced apart from an at least one second electrode,wherein the at least one second electrode is attached to a hand bearing surface,wherein the first electrode is configured for the placement of a thumb of a hand and the at least one second electrode is configured for the placement of at least one of an index finger, middle finger, ring finger, and little finger of the handwherein the at least one fingerprint sensor is attached to the at least one of the first electrode and the at least one second electrode,wherein the at least one electrical signal is modified by passing through the hand via the first electrode and at least one second electrode, andwherein an identification result can be established by the evaluation of the detected fingerprint and the evaluation of the at least one modified electrical signal.

Abstract
Arrangement and method for identifying fingerprints, including at least one fingerprint sensor and at least two electrodes, wherein a fingerprint can be detected by the sensor. A first electrode is arranged in the vicinity of a hand support surface at a distance from the support surface such that when a finger is placed on the support surface, the thumb can be placed on the first electrode. At least one second electrode is arranged on the support surface such that at least one finger can be placed on the second electrode. The sensor and the first electrode and/or the at least one second electrode are each designed as one unit. Electric signals are transmitted to the hand via the electrodes by a measuring unit for applying and analyzing the electric signals, and the changes of the electric signals are detected. An identification result is ascertained using the detected fingerprints and signals.

18. An arrangement for identifying fingerprints, comprising:
-
at least two electrodes; and a controller to apply and evaluate at least one electrical signal between the two electrodes, wherein a first electrode is spaced apart from an at least one second electrode, wherein the at least one second electrode is attached to a hand bearing surface, wherein the first electrode is configured for the placement of a thumb of a hand and the at least one second electrode is configured for the placement of at least one of an index finger, middle finger, ring finger, and little finger of the hand, wherein the at least one electrical signal is modified by passing through the hand via the first electrode and at least one second electrode, wherein the at least one second electrode is configured as a force-effect detection unit, wherein the electrical signals are only able to be applied to the respective electrode when a force greater than a predetermined threshold is applied to the force-effect detection unit, and wherein an identification result can be established by the evaluation of the detected fingerprint and the evaluation of the at least one modified electrical signal. - View Dependent Claims (19, 20)
