Unimodal biometric system uses only single trait of biometric for recognition and do not provide secured application. Multimodal biometric combines different physical and behavioral traits such as face and finger other traits such as skin color, age, height, hair color, eye color, provide reliable authentication because the nature of these t property in soft biometrics, it can be used with othe...

This paper proposes an enhanced method for personal authentication based on finger Knuckle Print using Gabor transform. In study shows that finger knuckle print (FKP) technique of a person can be used as a biometric trait in a biometric authentication system due to its uniqueness property. Hand-based person recognition provides a reliable, in low-cost and user-friendly viable solution for a ran...

Biometric systems are vulnerable to certain type of attacks at various points in the biometric model. A spoofing attack which is submitting a stolen, copied biometric trait to the sensor to gain unauthorized access to the biometric system is one among them. Multimodal biometric systems are designed to increase the accuracy of the biometric system, but they are more vulnerable to spoofing attack...

It is well-known that in any biometric systems the quality of the input data has a strong impact on the accuracy that the system may provide. The quality of the input depends on several factors, such as: the quality of the acquisition device, the intrinsic quality of the biometric trait, the current conditions of the biometric trait, the environment, the correctness of user interaction with the...

This appendix expands on information presented in Chapter Two. It begins with a definition of biometrics and related terms, and then describes the steps in the biometric authentication process, reviews issues of template management and storage, and addresses testing issues. The appendix concludes with a brief review of mainstream biometric applications. 1 DEFINITIONS A biometric is any measurab...

We introduce a new way for generating strong keys from biometric data. Contrary to popular belief, this leads us to biometric keys which are easy to obtain and renew. Our solution is based on two-factor authentication: a low-cost card and a biometric trait are involved. Following the Boneh and Shacham group signature construction, we introduce a new biometric-based remote authentication scheme....

A biometric system is essentially a pattern recognition system being used in adversarial environment. Since, biometric system like any conventional security system is exposed to malicious adversaries, who can manipulate data to make the system ineffective by compromising its integrity. Current theory and design methods of biometric systems do not take into account the vulnerability to such adve...

Biometric databases are the set of biometric features collected from a large public domain for the evaluation of biometric systems. For the evaluation of any algorithm for a particular biometric trait, the database should be a large collection of that particular biometric trait. The creation and maintenance of biometric databases involve various steps like enrollment and training. Enrollment is...

INTEGRATION OF MULTIPLE CUES IN BIOMETRIC SYSTEMS By Karthik Nandakumar Biometrics refers to the automatic recognition of individuals based on their physiological and/or behavioral characteristics. Unimodal biometric systems perform person recognition based on a single source of biometric information and are affected by problems like noisy sensor data, non-universality and lack of individuality...

Essentially a biometric system is a pattern recognition system which recognizes a user by determining the authenticity of a specific anatomical or behavioral characteristic possessed by the user. With the ever increasing integration of computers and Internet into daily life style, it has become necessary to protect sensitive and personal data. This paper proposes a multimodal biometric system w...
