Abstract
The invention relates to a method for identification of a person by recognition of a digital fingerprint, whereby the characteristic points on a digitized image of a digital fingerprint (E) are determined and transmitted () to a bank holding () the characteristic points of a number of digital fingerprints for comparison and identification () of the person to whom the photographed fingerprint belongs. When the fingerprint (E) is taken on a curved surface () of an object (), the digitised mage is transformed () into a plane-projection corrected digitised image, by means of an algorithm, in which the characteristic points are detected ().
