METHOD OF IDENTIFYING LIVING FINGER

摘要

FIELD: physics; image processing. ^ SUBSTANCE: present invention relates to dactylography and can be used for preventing unauthorised access to a protected system by random persons. The method of identifying a living finger is based on comparing distinctive features of a papillary figure when a finger is pressed twice to the receiving surface of a scanner. The degree of linearity of displacement of coordinates of the distinctive features of the papillary figure determines whether the finger is living. ^ EFFECT: increased security of the system. ^ 2 dwg
