    In the era of Information Technology, openness of the information is a major concern. As the confidentiality and integrity of the information is critically important, it has to be secured from unauthorized access. Security refers to prohibit some unauthorized persons from some important data or from some precious assets. So we need accurateness on automatic personal identification in various applications such as ATM, driving license, passports, citizen's card, cellular telephones, voter's ID card etc. Unimodal system carries some problems such as Noise in sensed data, Intra-class variations, Inter-class similarities, Non-universality and Spoof attacks. The accuracy of system is improved by combining different biometric traits which are called multimodal. This system gives more accuracy as it would be difficult for imposter to spoof multiple biometric traits simultaneously. This paper reviews different methods for fusion of biometric traits

    Una de las mayores dificultades en el reconocimiento de patrones y en particular en sistemas biom茅tricos basados en la palma de la mano, es obtener en el preprocesamiento un adecuado c谩lculo de la regi贸n de inter茅s (ROI) ya que esta influye directamente en los resultados finales del sistema de identificaci贸n, teniendo en cuenta que estos sistemas son implementados en procesos delicados, donde el rendimiento se encuentra afectado directamente tanto por la selecci贸n de la t茅cnica de clasificaci贸n, como por el tratamiento inicial de la base de datos y en definitiva lo que se pretende alcanzar es una tasa de error nula ya sea ante una verificaci贸n o una identificaci贸n de personas. El proyecto presenta una metodolog铆a para la validaci贸n de la incidencia de la ROI en la identificaci贸n biom茅trica de personas mediante un sistema de reconocimiento de la palma de la mano, donde la extracci贸n de caracter铆sticas se realiza mediante la implementaci贸n de t茅cnicas de procesamiento digital de im谩genes orientadas al an谩lisis de texturas en niveles de gris, en particular, Patrones binarios Locales. La validaci贸n de la robustez del sistema se realiza empleando t茅cnicas convencionales de clasificaci贸n, previo estudio de la relevancia y efectividad de las caracter铆sticas estimadas.Magister en Automatizaci贸n y Contro

    In this work, a new approach for personal authentication using palm image is presented. We design three ensembles of matchers which employ different feature representation schemes of the images: Discrete Cosine Coefficients; Invariant Local Binary Patterns; Gabor Filters. Each ensemble is obtained by varying the features used to train their matchers. Experimental results confirm that the three methods give complementary information which has been exploited by fusion rules. Finally, we combine our Palm based method system with other biometric characteristics that can be extracted from the hand (middle finger, ring finger, hand geometry), obtaining a further improvement of the performance
