    AN EFFICIENT SECURE BIOMETRIC SYSTEM USING NONINVERTIBLE GABOR TRANSFORM
    (IJCSI International Journal of Computer Science, 2011-09) Radha N; Karthikeyan S
    Biometric scheme are being widely employed because their security merits over the earlier authentication system based on records that can be easily lost, guessed or forged. High scale employments and the related template storage have increased the requirement to guard the biometric data stored in the system. Theft of biometric information is a negotiation of the user’s privacy. In Addition, the stolen biometric information can be used to access other biometric systems that have the similar feature provided for the user. Several alternative functions have been identified in literature for creating revocable or noninvertible biometric templates. Although, their security examination either disregards the distribution of biometric features or uses inefficient feature matching. This generally shows the way to unrealistic approximation of security. In this paper a novel approach for the Non-Invertible biometric system is proposed to secure the biometric template. Security of a feature transformation method can be assessed according to the two main factors: i) non-invertibility, and ii) diversity. Non-invertibility represents the complexity in obtaining the original biometric when the secure template is provided and diversity represents the complexity in guessing one secure template when a different secure template created from the identical biometric is provided. The proposed Non-invertible Gabor transform possess both the non-invertible and diversity features which enhances the security of the system to a large extent. The proposed approach is very much resistant to minor translation error and rotation distortion. The experimental result shows the better performance of the proposed technique compared to the existing system

    SECURING RETINAL TEMPLATE USING QUASIGROUPS
    (Special Issue of Security Issues and Solutions for Information, Computer and Networks, Journal of Advances in Information Technology (JAIT), 2011-05) Radha N; Rubya T; Karthikeyan S
    Biometric plays important role in person recognition and identification. It is more secure than the traditional systems like password and token-based systems. The traditional systems can be stolen, misplaced or destroyed. But the biometric systems are based on the physiological or behavioral traits of the individual human being. It cannot be altered or misused by the unauthorized persons. It is more reliable than the traditional systems. Although it is powerful, immutable to vulnerable attacks So it is necessary to secure the biometric template using more efficient techniques. Cryptography is the most powerful technique to avoid vulnerable attacks. Recently it was found that the non-associative property of quasigroup helps achieving better security by having a randomly generated key for encr1yption. The operations involved in Quasigroup are computationally simple and can be efficiently used for protection of voluminous media like images, audio, video and different forms of multimedia in this paper the Quasigroup technique is used to provide better security to Retina Template
