Abstract
Biometrics refers to the automatic recognition of individuals based on their biological or behavioral characteristics. In fingerprint biometric system, a template security is essential to safeguard the templates from an attacker intruder. In the existing system, alignment free fingerprint cryptosystem performs matching using relative information between minutiae. The existing system uses multi biometric system which leads to high processing time and speed. The focus is to improve speed and performance of the system and to reduce false acceptance and false rejection rate. Hence to overcome this problem, a new fingerprint template security has been proposed using Turtle encryption scheme. In this study, the system generates a feature vector from the fingerprint template and by detecting the core point, minutiae direction is generated. Based on the new extracted features, the matrix form is generated. Then by using the turtle encryption algorithm, a new encrypted feature vector is generat
