Survey of Fingerprint Matching Techniques for Privacy Protection

Now-a-days identification of fingerprint is an active area of research. In most areas we are using recognition of fingerprint for improving the privacy and security. The recognition is done by using methods of fingerprint matching. Matching methods can be of two types-verification of fingerprint and identification of fingerprint. Combination of fingerprint for protecting privacy is a system for guarding fingerprint isolation by integrating two distinct fingerprints into new indirect identity. Fingerprints are taken from FVC databases. In the enrolment phase two fingerprints will be taken from two distinct fingers. We will take out the minutiae position from one fingerprint, from other orientation and from both points of references are taken out. From the information taken out an impression of combined minutiae is generated and deposited in the database. In authentication phase system requires two fingerprints from similar two fingers which were used previously during enrolment time. A minutia cylinder code matching algorithm is recommended for matching the two fingerprints query against template of combined minutiae. By keeping combined minutiae template, full attributes of single fingerprint will not be recognized even if the database is grabbed. As there is likeness in topology it is not possible for raider to draw out a template of combined minutiae from actual templates of minutiae. Thus a new virtual identity is generated for disparate two fingerprints. Key Termsidentification, recognition, FVC database, minutia cylinder code, combination, fingerprints.
