Abstract
The invention relates to a method for testing a fingerprint whose reference data are stored in a portable data carrier. The reference data contain at least positions and orientations of minutiae and pores and an orientation vector. According to the invention it is provided that the testing of the fingerprint includes first sensing measuring values stating the actual value of the sensed fingerprint and extracting the minutiae and the pores from said measuring values. Then the reference data of the minutiae and the orientation vector are read from the portable data carrier and the minutiae from the sensed fingerprint compared with the corresponding reference data. Subsequently, the position of the pores relative to the minutiae is transmitted to the portable data carrier and the pores are checked in the portable data carrier.
