A secure and private fingerprint-based authentication system

In this paper we propose a secure and private fingerprint-based authentication system.First the user of the system ought to register his or her fingerprints to a server database of fingerprint-minutiae templates, which are generated from the original fingerprint images and then are inserted with a number of foreign minutiae.Upon authentication the same live fingerprint will be measured again to regenerate a template, which will then be matched against the stored templates.The regenerated template will be discarded once the match is done.The new system is secure and private because of the insertion of large numbers of foreign minutiae to the database templates and no other template will be stored.Our testing results show the proposed system is promising.
