While it is widely acknowledged that the performance improvement in current biometrics-based personal authentication systems is necessary, it is not clear what mechanisms could be used to improve the performance. In this paper, we formulate the problem of multiple biometrics integration and examine whether the improvement in performance could be achieved from integrating multiple biometrics. Fo...

W ITH A very security-conscious society, biomet-rics-based authentication and identification have become one of the key technologies for many important applications. It is generally believed that biometrics can provide the necessary accuracy and reliability for applications, such as access control. Biometrics research and technology continue to mature rapidly, driven by pressing industrial and ...

Despite their usability advantages over traditional authentication systems, biometrics-based authentication systems suffer from inherent privacy violation and non-revocability issues. In order to address these issues, the concept of cancelable biometrics was introduced as a means of generating multiple, revocable, and noninvertible identities from true biometric templates. Apart from BioHashing...

This paper advances an analysis of biometrics and profiling. Biometrics represents the most effective technology in order to prove someone’s identity. Profiling regards the capability of collecting and organizing individuals’ preferences and attitudes as consumers and costumers. Moreover, biometrics is already used in order to gather and manage biological and behavioral data and this tendency m...

© 1998 Journals of Reproduction and Fertility 1359-6004/98 $12.50 Before mammalian spermatozoa can interact with the egg in vivo, they are subjected to post-testicular modifications in the male as well as in the female genital tract. The evidence that this post-testicular maturation process requires exposure to a specific microenvironment within the epididymis has been reviewed elsewhere (Orgeb...

Personal identification and authentication is very crucial in the current scenario. Biometrics plays an important role in this area. Biometric based authentication has proved superior compared to traditional password based authentication. Anyhow biometrics is permanent feature of a person and cannot be reissued when compromised as passwords. To over come this problem, instead of storing the ori...

Currently, small and large scale businesses are in need of advanced security measures to keep both customers and employees safe from today’s possible dangers. An excellent method of security, which is almost essential, is to identify a person quickly, easily and accurately. This type of security hasn’t been accomplished and proven through modern day technology up until now. We describe the tech...

This study investigated the protective effects of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced testicular toxicity in male rats. DADS was gavaged to rats once daily for 3 days at 100 mg/kg/day. One hour after the final DADS treatment, the rats were given a single intraperitoneal dose of 150 mg/kg CP. All rats were killed and necropsied on day 56 after CP treatment. Parameters ...

BACKGROUND & OBJECTIVES Polychlorinated biphenyls (PCB), the synthetic chlorinated organic compounds, are known to decrease thyroid function, sperm count and fertility, and increase the risk of testicular cancer may cause serious effect on male reproduction. The objective of the present study was to study the effect of PCB, Aroclor 1254 on rat epididymal structure and function. METHODS Adult ...

BACKGROUND There are still concerns about the safety of intracytoplasmic sperm injection (ICSI) due to its brief clinical record and lack of animal testing. Testicular and epididymal sperm are now used routinely for ICSI in patients with obstructive azoospermia. The use of such immature sperm compounds fears, since little is known of their mitochondrial and nuclear DNA quality. METHODS A modi...
