Fingerprint fuzzy vault chaff point generation by squares method

Abstract

In the literature, several abscissae generation methods of chaff points in fingerprint fuzzy vault exist. In this paper, we make an experimental comparison between squares method and threshold methods. The experimental results show that the squares method is far better than methods based on threshold. But minutiae representation in squares method use 2D representation while threshold methods are represented by composite representation. We proposed to implements squares methods using composite representation and made same experiments which showed less gain of time.

“…This approach has good recognition accuracy (GAR of 86.03% and FAR of 0.39%) and does not require the alignment of reference and query templates during authentication. Recent works focus on the development of new methods of alignments for fingerprint-based fuzzy vaults [63] as well as the use of circle packing [64] and squares method [65] techniques to provide fast and less complex chaff-point generation. These approaches lead to a reduction in the amount of time required for enrolment and authentication.…”
