Method for the identifying evaluation of the individual-characteristic skin ridge patterns of the finger berries, which can be classified on the basis of certain basic types and are determined by the papillary body of the skin.

General information
This section has been translated automatically.

The fingerprint is by definition an unchangeable, individually imprinted and fixed impression of the papillary ridges on the volar end phalanx of a finger (fingertip or fingertip berry). Criminology thus assumes that the fingerprint is unique and unchangeable (scarring injuries are excluded). Even in the case of identical twins, different prints are found.

A distinction is made between different characteristics of the fingerprint:

  • Basic pattern
  • rough characteristics like loops, curves, coils
  • finer features: Suction. minutiae
  • Pore structure and pore spacing

Changes in the dactylogram (loss of papillary ridges of the fingers) are observed under chemotherapy (capecitabine), especially if a hand-foot syndrome has occurred. Furthermore, long-term topical application of glucocorticoids may also cause loss of finger groin relief.
