---------------------------------------------------------------------***--------------------------------------------------------------------Abstract-Biometric authentication systems are gaining widespread popularity in recent years due to the advances in sensor technologies as well as improvements in the matching algorithms. Preserving the privacy of digital biometric data stored in a central database has become of paramount importance. VCS is a cryptographic technique that allows for the encryption of visual information such that decryption can be performed using the human visual system. There are various measures on which performance of visual cryptography scheme depends, such as pixel expansion, contrast, security, accuracy, computational complexity, share generated is meaningful or meaningless, type of secret image. This technique encrypts a secret image into shares such that stacking a sufficient number of shares reveals the secret image. The stored images are encrypted and while verification that images are decrypted. This work implements visual cryptography for color images in a biometric application. The project modules have a strong authentication and robustness scheme. Keywords:Fingerprint Image, Biometric, Cryptography, Enrollment, Authentication

1. Introduction BIOMETRICS is the science where identity of an individual based on physical and behavioral traits such as face, fingerprints, iris, retina and voice. For automated personal identification biometric authentication is getting more attention. When biometric authentication is used, system operates by getting raw biometric data from a subject then extracts the feature set from a subject and compare that feature set with the template stored in database, the template of a person in the database is generated during enrollment and is often stored with original raw data. To deal with the security problems of secret images, various image secret sharing schemes have been developed. Visual cryptography is introduced first by Noar and Shamir in 1994. Visual cryptography is a cryptographic technique Š 2017, IRJET

which allows visual information (e.g. printed text, handwritten notes and pictures) to be encrypted in such a way that the decryption can be performed by the human visual system, without the aid of computers. Visual cryptography scheme eliminates complex computation problem in decryption process, and the secret images can be restored by stacking operation. In this work, the use of visual cryptography is explored to protect the privacy of biometric data (raw image). In this technique first the private image is decomposed into two images in such a way that the original image can be obtained only when both the original image is available further the individual image cannot create private image. Fig 1 shows block diagram of the proposed approach. During the enrollment process, the private biometric data is sent to trusted entity once the trusted party acquires it the biometric data is transferred into two images and original data is removed. The created components are then transmitted and stored in two different databases. During the identification process the trusted entity sends request to each server and corresponding sheets are sent. Sheets are overlaid to each other to create the original image. The remaining work is organized as follows: section 2 discussed about the previous work, Section 3 describes the methodology used for fingerprint authentication, Section 4 shows the experimental result for the proposed methodology and Section 5 summarizes the conclusion of this work.
2. Literature Survey Preserving the privacy of digital biometric data (e.g., face images) stored in a central database has become of paramount importance. Ross and Asem (2011) explores the possibility of using visual cryptography for imparting privacy to biometric data such as fingerprint images, iris codes, and face images.Biometrics Systems consists of the physical and behavioral features for e.g. face, fingerprints etc. So Rajanwar et al introduced a design to protect biometrics data from the various attacks. Here using the concept of visual cryptography, where cryptography is the concept of sending
