Protection of fingerprint data with the glass maze algorithm

Abstract

This work proposes an implementation of the glass maze algorithm proposed by Carlo A. Trugenberger and presents a short summary of its theoretical basis. The implementation is roughly tested with synthetic fingerprints and the experimental results and findings during the testing phase regarding security issues and performance are discussed. It could be seen, that even though from a theoretical standpoint the system seems to be stable against brute force attacks, under certain circumstances the system may still be vulnerable to brute force attacks.
