Privacy Preserving in Multimodal Biometrics Via Piecewise Polynomial Filtering Function

A.P.Caroline Hirudhaya, A. Pethalakshmi


Confirming the identity of a person is the important criteria to access through the confidential services on the net. The confirmation of identity is done through various methods like passwords, pin numbers, and biometrics features. The field of identification using biometrics expands from unimodal biometrics to multimodal biometrics. In multimodal biometrics the modalities may differ. In this paper three modes of biometric traits are combined using various fusion techniques. We propose piecewise polynomial filtering function to enhance the privacy of the system.

Keywords: biometrics, traits, fusion techniques, piecewise polynomial filtering
