Abstract

This bachelor`s thesis deals with the creation of a realistic looking fingerprint with a double identity. The goal is the design and subsequent implementation of an algorithm to create such a morphed fingerprint. The morphing consists of three important steps, extracting the information from the fingerprint, morphing the information to generate a new fingerprint, and verifying the morphed fingerprint against both originals to evaluate the double identity rating. As an extension, an algorithm for blurring the edges of a morphed fingerprint was implemented, the Minutia Cylinder-Code SDK was integrated into the application to immediately obtain double identity rating, and the method of obtaining suitable identities from the original fingerprints was modified to improve results. The implemented algorithms were tested on a fingerprint database, where it was shown that in the absence of damage, the information from the fingerprint is reliably extracted, from 90 % cases the morphed fingerprint acquired two identities and from 60 % it also had a realistic appearance.
