Fingerprint combination for privacy protection is a novel system for defensive fingerprint privacy by coalescing two dissimilar fingerprints into a new identity. Fingerprints are captured using a biometric scanner in real time. In the enrolment, two fingerprints are captured from two dissimilar fingers. An improved adaptive fingerprint enhancement method based on contextual filtering is used to process the images. Four updated blocks are preprocessing, global analysis, and local analysis, matched filtering. The minutiae loci from one fingerprint, the orientation from the other, and the reference points from both fingerprints are extracted. Based on this extracted information, a combined minutiae template is engendered and warehoused in a database.
