Can Fingerprints be Reconstructed from ISO Templates?

For a long time it has been assumed that a minutiae-based fingerprint template did not contain enough information to allow reconstructing the original fingerprint image. This work proposes an approach to reconstruct fingerprint images from ISO standard templates and investigates to what extent the reconstructed fingerprints are similar to the original ones. The results show that the reconstructed images have a very good quality and may be used to attack existing fingerprint recognition systems. Systematic studies to understand the success chances of such attacks are currently being carried out
