Fingerprint Combination System Based on Protection of Virtual Identity

A fingerprint authentication system for the privacy protection of the virtual identity is introduced. By extracting minutiae points from one fingerprint, orientation from other fingerprint and reference points from both the fingerprints, a new biometric authentication framework is proposed for identifying an individual. With the help of these three combined features a new virtual identity is generated. A combined biometric composed of two fingerprints is stored in the server database, and query fingerprints from both fingers are required in the verification process which reduces loss of privacy and misuse. The main intention of this paper focuses on the security and privacy of a virtual identity. In order to attain high security and privacy Liveness Detection technique is applied to distinguish legitimate and imposter user. To protect the virtual identity templates Delaunay quadrangle based fingerprint authentication system which deals with nonlinear distortion-induced local structural change. Finally the virtual identity is compressed and stored in database for further verification process.
