    The increasing demand of security oriented to mobile applications has raised the attention to biometrics, as a proper and suitable solution for providing secure environment to mobile devices. With this aim, this document presents a biometric system based on hand geometry oriented to mobile devices, involving a high degree of freedom in terms of illumination, hand rotation and distance to camera. The user takes a picture of their own hand in the free space, without requiring any flat surface to locate the hand, and without removals of rings, bracelets or watches. The proposed biometric system relies on an accurate segmentation procedure, able to isolate hands from any background; a feature extraction, invariant to orientation, illumination, distance to camera and background; and a user classification, based on k-Nearest Neighbor approach, able to provide an accurate results on individual identification. The proposed method has been evaluated with two own databases collected with a HTC mobile. First database contains 120 individuals, with 20 acquisitions of both hands. Second database is a synthetic database, containing 408000 images of hand samples in different backgrounds: tiles, grass, water, sand, soil and the like. The system is able to identify individuals properly with False Reject Rate of 5.78% and False Acceptance Rate of 0.089%, using 60 features (15 features per finger

    10 pages, 8 figures.-- Contributed to: V Jornadas de Reconocimiento Biométrico de Personas (JRBP 2010, Huesca, Spain, Sep 2-3, 2010).En el presente artículo se pretende estudiar las prestaciones de un sistema de reconocimiento biométrico mediante firma manuscrita usando la teoría de Análisis Formal de Conceptos (FCA). Se usará la modalidad online de la firma manuscrita, con un algoritmo basado en Máquinas de Vectores Soporte (SVM). Para analizar el desempeño del sistema se realizará un estudio de su matriz de confusión usando el Análisis de Conceptos Formales, y se procederá a extraer conclusiones sobre el sistema.Publicad

    Producción CientíficaActualmente la implantación de la identificación biométrica en la vida cotidiana se encuentra en pleno desarrollo. Aun así y pese a una mayor difusión de la misma y su empleo en aplicaciones que requieren seguridad, hoy en día existe un rechazo por parte del usuario debido a ideas preconcebidas y a falsos mitos. Parte del origen de dichas ideas erróneas se debe a la visión que se le da a la biometría en las películas y series de ciencia ficción. Este rechazo, a su vez, se manifiesta también en forma de miedo ya sea por cuestiones de seguridad física, aspectos legales o por temor a perder el anonimato. En el presente artículo, los autores realizan un estudio sobre la aceptación y la respuesta del usuario ante esta tecnología analizando el comportamiento y la reacción de las personas frente a algunas de las principales modalidades biométricas y sus dispositivos. Dicho estudio se ha llevado a cabo durante una labor de divulgación acerca de la biometría y de la base científico-tecnológica sobre la que se encuentra desarrollada en la IX Feria Madrid es Ciencia
