An alignment-free fingerprint bio-cryptosystem based on modified Voronoi neighbor structures

作者：

Highlights：

• We propose an alignment-free fingerprint bio-cryptosystem based on modified VNSs.

• The scheme is able to compensate the VNS change caused by large non-linear distortion.

• Encrypted matching is performed and protected by the secure sketch, PinSketch.

• The Experimental results show the validity of the proposed scheme.
