Fingerprint is a popular biometric modality which is used extensively in several applications for person
authentication, providing high uniqueness and acceptable performance. Most fingerprint systems use
minutiae-based representations. However, several studies have proven that the original fingerprint
impression can be reconstructed from minutia information, which makes the problem of ensuring the
security of fingerprint data very critical. In this paper, we present a new approach for fingerprint template
protection. Our objective is to build a non-invertible transformation that meets the requirements of revocability ,
diversity, security and performance. In this context, we exploit the information provided by the
extracted minutiae to construct a new representation based on special spiral curves, which can be used
for the recognition task instead of the traditional minutiae-based representation. The proposed approach
has been evaluated using the original FVC protocol and compared with existing protection approaches
which use the same protocol. Our experimental results illustrate the ability of the proposed representation
to preserve the performance of protected systems. Moreover, we demonstrate that the security of
our approach is sufficiently robust to the zero effort and brute force attacks.
