This work reports a preliminary study on the vulnerability evaluation of fingerprint verification systems to direct attacks carried out with fake fingertips created from minutiae templates. The attack is performed by presenting to the acquisition sensor a fake fingertip generated from an image reconstructed from a compromised minutiae-based template. Experiments carried out against a state-of-the-art...
A minutiae-based template is a very compact representation of a fingerprint image, and for a long time, it has been assumed that it did not contain enough information to allow the reconstruction of the original fingerprint. This work proposes a novel approach to reconstruct fingerprint images from standard templates and investigates to what extent the reconstructed images are similar to the original...
