Biometric systems have a variety of problems such as noisy data, non-universality, spoof attacks and unacceptable error rate. These limitations can be solved by deploying multimodal biometric systems. Multimodal biometric systems utilize two or more individual traits, like face, iris, retina and fingerprint. Multimodal biometric systems improve the recognition accuracy more than uni-modal metho...

The system explores the possibility of combining two biometric systems for generating virtual identities. In biometric system the physical or behavioural traits are used for fusion. Biometric authentication provides high level of security. The proposed approach is to combine the palm print and fingerprint image using an appropriate fusion scheme. The comparison of database template and the inpu...

A biometric system which relies only on a single biometric identifier in making a personal identification is often not able to meet the desired performance requirement. The basic aim of a biometric identify system is to make distinction automatically between subjects in a reliable and dependable way, according to a specific-target application. Multimodal Biometric systems aim to fuse two or mor...

Multimodal biometric systems consolidate the evidence presented by multiple biometric sources and typically provide better recognition performance compared to systems based on a single biometric modality. Although information fusion in a multimodal system can be performed at various levels, integration at the matching score level is the most common approach due to the ease in accessing and comb...

Biometric recognition is still a very difficult task in realworld scenarios wherein unforeseen changes in degradations factors like noise, occlusion, blurriness and illumination can drastically affect the extracted features from the biometric signals. Very recently Haar-like rectangular features which have usually been used for object detection were introduced for biometric recognition resultin...

Biometrics offers natural and scientific solution to key aspects of security management problems. Due to the increased security concerns in the past decade, biometrics has seen enormous growth and has found widespread applications in our everyday life. Widely researched biometrics traits include face, iris, fingerprint, hand geometry, palmprint, voice and signature. Of these, face and hand geom...

objective: to review her-2/neu and tp53 status and their correlation with all other prognostic clinicopathologic features of infiltrative ductal breast carcinomas. materials and methods: this cross sectional study was performed on 139 patients with infiltrative ductal breast carcinoma who were diagnosed between may 2000 and march 2006 at the surgery and pathology departments of alzahra hospital...

background: interleukin-19, a member of the interleukin-10 family of cytokines, contributes to breast cancer pathogenesis. high interleukin-19 expression in breast tumor tissues is associated with poor clinical outcome. this study aimed to assess the changes in serum level of interleukin-19 in breast cancer patients in comparison with normal women and its association with the clinicopathologica...

a bstract background: recent attempts have been focused on employing chemical and natural supplemental agents for treatment of cyclic mastalgia. among various agents, the potential effects of vitamins remain questionable. in the present study, we examined the efficacy of two types of these vitamin supplements (vitamin e and vitamin b6) in improving pain severity in cyclic mastalgia.   materials...

Biometric techniques are gaining importance for personal authentication and identification as compared to the traditional authentication methods. Biometric templates are vulnerable to variety of attacks due to their inherent nature. When a person’s biometric is compromised his identity is lost. In contrast to password, biometric is not revocable. Therefore, providing security to the stored biom...
