the present study investigated the calpain gene diversity in iranian one-hump camels (120 camels) using pcr-rflp method. three genotypes aa, ag and gg were observed with the frequencies of 0.02, 0.19 and 0.78, respectively. the frequencies of a and g alleles were 0.12 and 0.88, respectively. the chi-squared test didn’t show significant deviations from hardy-weinberg equilibrium (p<0.05). associ...

Soft biometric trait has been used as ancillary information to enhance the recognition accuracy for face, fingerprint, gait, iris, etc. In this paper, we present a new investigation of soft biometric trait to improve the performance of finger vein recognition. We first propose some extraction criteria of soft biometric trait for comprehensively understanding this kind of ancillary information. ...

Digital human identity management, can now be seen as a social necessity, as it is essentially required in almost every public sector such as, financial inclusions, security, banking, social networking etc. Hence, in today’s rampantly emerging world with so many adversarial entities, relying on a single biometric trait is being too optimistic. In this paper, we have proposed a novel end-to-end,...

User verification systems that use a single biometric indicator often have to contend with noisy sensor data, restricted degree of freedom, non-universality of the biometric trait and unacceptable error rates. So the need of using multimodal biometric system occurred. A multimodal biometric system combines the different biometric traits and provides better recognition performance as compared to...

Nowadays biometric authentication systems have been more developed, especially in secure and financial systems; so cracking a biometric authentication system is now a growing concern. But their security has not received enough attention. Imitating a biometric trait of a genuine user to deceive a system, spoofing, is the most important attacking method. Multi biometric systems have been develope...

Traditional user authentication/verification systems mostly rely on knowledge; like password or smart card. But they are not able to meet strict security performance of today’s computer applications. That’s why now biometrics-based authentication systems are good alternate to these traditional authentication methods. Biometric system works on the principle of recognizing individuals on the basi...

Feature level based monomodal biometric systems perform person recognition based on a multiple sources of biometric information and are affected by problems like integration of evidence obtained from multiple cues and normalization of features codes since they are heterogeneous, in addition of monomodal biometric systems problems like noisy sensor data, non-universality and lack of individualit...

A biometric is a unique feature, a measurable trait or characteristic which is utilized in automatically identifying or verifying the identity of a human being. An assortment of inevitable shortcomings has been faced by unimodal biometric recognition like Limited discriminability, noisy biometric data, Upper bound in performance and Lack of permanence, consequence dilapidation of exactness and ...
