Analysis of Fingerprint Spoofs Created from Mold Done by Burning Technique
 Sochová, Terézia ; Sakin, Martin (oponent) ; Kanich, Ondřej (vedoucí práce)
This work is devoted to the production and analysis of fingerprint spoofs created from mold using a burning technique. The aim of this work is to create fingerprints spoofs from different materials and then to design and to implement an algorithm that compares spoofs with model fingerprints. Spoofs are made using beech wood molds. In order to create the fingerprints, plasteline, silicone and liquid latex are used. The analysis of the differences between fingerprint spoofs and their real fingerprints is based on the minutiae extraction and on their subsequent processing. The results of analysis are represented by three monitored metrics: number and type of minutiae, number of paired minutiae and average distance difference between fingerprint spoof minutiae and real fingerprint minutiae. The created program is tested using a database of produced fingerprint spoofs. The results of the program are compared with the results of the VeriFinger application. Both programs agreed that spoofs made by silicone are the ones of the highest quality.
