An Analytical Study on integration of Multibiometric Traits at Matching Score Level using Transformation Techniques
نویسندگان
چکیده
Biometric is one of those egressing technologies which are exploited for identifying a person on the basis of physiological and behavioral characteristic. However, unimodal biometric system faces the problem of lack of individuality, spoof attacks, non-universality, degree of freedom etc., which make these systems less precise and erroneous. In order to overcome these problems, multi biometric has become the favorite choice for verification of an individual to declare him as an imposte or a genuine. However, the fusion or integration of multiple biometric traits can be done at any one of the four module of a general multibiometric system. Further, achieving fusion at matching score level is more preferable due to the availability of sufficient amount of information present over there. In this paper we have presented a comparative study of normalization methodology which is basically used to convert the different feature vectors of individual traits in common domain in order to combine them as a single feature vector. Keywords— Biometric, Multibiometric, Normalization, Unimodal, Unsupervised Learning rules, Imposter, Genuine.

Abstract: A Multimodal Fusion Algorithm Based on FRR and FAR Using SVM
Remarkable improvements in recognition can be achieved through multibiometric fusion. Among various fusion techniques, score level fusion is the most frequently used in multibiometric system. Already existing score level fusion approaches can be categorized into three classes: transformation-based, density-based and classifierbased. In this paper, advantages and disadvantages of the three fusio...

Remarkable improvements in recognition can be achieved through multibiometric fusion. Among various fusion techniques, score level fusion is the most frequently used in multibiometric system. In this paper, we propose a novel fusion algorithm based on False Reject Rate (FRR) and False Accept Rate (FAR) using Support Vector Machine (SVM). It transfers scores into corresponding FRRs and FARs, thu...
متن کاملAn Improved Semantic Schema Matching Approach
Schema matching is a critical step in many applications, such as data warehouse loading, Online Analytical Process (OLAP), Data mining, semantic web [2] and schema integration. This task is defined for finding the semantic correspondences between elements of two schemas. Recently, schema matching has found considerable interest in both research and practice. In this paper, we present a new impr...
متن کاملFuzzy Fusion in Multimodal Biometric Systems
Multimodal authentication systems represent an emerging trend for information security. These systems could replace conventional mono-modal biometric methods using two or more features for robust biometric authentication tasks. They employ unique combinations of measurable physical characteristics: fingerprint, facial features, iris of the eye, voice print, hand geometry, vein patterns, and so ...
