TL;DR: The main objective of this system is to design and implement a fingerprint biometric security system to transform the original template that is free from all the vulnerabilities by reducing the False Acceptance Rate and improving the False Rejection Rate.
Abstract: In today's materialistic world security holds an indispensable place. There is a need for security in almost every sector of the society. To overcome the threat, a security system has been proposed using Fingerprint Authentication. Storing the fingerprint template as it is in the database, results in the compromise of one's identity if the database is stolen or hacked. Henceforth, the template has to be made secure by applying a transformation that makes the attacker's possibility of revoking back to the original Fingerprint Template infeasible. This approach uses three different transformations to secure the template. Three different transformation functions namely Conformal, Isogonal and Indirectly Conformal mapping functions are selected and are applied to the original fingerprint template and the effectiveness of each transformation is comparatively analyzed. The main objective of this system is to design and implement a fingerprint biometric security system to transform the original template that is free from all the vulnerabilities by reducing the False Acceptance Rate and improving the False Rejection Rate. The system using conformal mapping has an Equal Error Rate (EER) of 2.8%, the system using isogonal mapping has an EER of 3% and finally the system using indirectly conformal mapping has an EER of 2.7%.

TL;DR: A method is proposed to generate a revocable fingerprint template in terms of bit-string from a set of minutiae points via a polar grid based 3-tuple quantization technique.
Abstract: Recently, biometric template protection has received great attention from the research community due to the security and privacy concerns for biometric template. Although a number of biometric template protection methods have been reported, it is still a challenging task to devise a scheme which satisfies all of the four template protection criteria namely diversity, revocability, non-invertibility and performance. In this paper, a method is proposed to generate a revocable fingerprint template in terms of bit-string from a set of minutiae points via a polar grid based 3-tuple quantization technique. Two merits of the proposed method are outlined, namely alignment-free and performance. Four publicly available benchmark datasets: FVC2002 DB1, DB2 and FVC2004 DB1, DB2 are used to evaluate the performance of the proposed method. Besides, the diversity, revocability, non-invertibility criteria are also analyzed.

Abstract: In this study, the authors propose a novel fingerprint template protection scheme that is developed using Delaunay triangulation net constructed from the fingerprint minutiae. The authors propose two methods namely FS_INCIR and FS_AVGLO to construct a feature set from the Delaunay triangles. The feature set computed is quantised and mapped to a 3D array to produce fixed length 1D bit string. This bit string is applied with a DFT to generate a complex vector. Finally, the complex vector is multiplied by user's key to generate a cancellable template. The proposed computation of feature set maintained a good balance between security and performance. These methods are tested on FVC 2002 and FVC 2004 databases and the experimental results show satisfactory performance. Further, the authors analysed the four requirements namely diversity, revocability, irreversibility and accuracy for protecting biometric templates. Thus, the feasibility of proposed scheme is depicted.
