Mixing fingerprints for generating virtual identities

This work explores the possibility of mixing two different fingerprints at the image level in order to generate a new fingerprint. To mix two fingerprints, each fingerprint is decomposed into two different components, viz., the continuous and spiral components. After pre-aligning the components of each fingerprint, the continuous component of one fingerprint is combined with the spiral component of the other fingerprint image. Experiments on a subset of the WVU fingerprint dataset show that the proposed approach can be used to generate virtual identities from images of two different fingers pertaining to a single individual or different individuals.
