Abstract
Un método para verificar la presencia de una cara viva delante de una cámara (112), comprendiendo el método: capturar mediante dicha cámara una secuencia de imágenes de una cara; detectar una pluralidad de características de dicha cara en cada una de dichas imágenes; medir parámetros asociados con dichas características detectadas para determinar si cada uno de una pluralidad de indicadores de vida está presente en dichas imágenes; caracterizado por que el método comprende: determinar una puntuación de parámetros para cada uno de dichos indicadores de vida basándose en dichos parámetros medidos y comparar cada una de dichas puntuaciones de parámetros con al menos un umbral; generar una puntuación intermedia basándose en la presencia determinada de cada uno de dichos indicadores de vida; determinar si dicha cara es o no una cara viva basándose en la presencia en dichas imágenes de una combinación de al menos dos de dichos indicadores de vida, comprendiendo: ajustar dicha puntuación intermedia si se detecta en dichas imágenes la presencia de dicha combinación de al menos dos indicadores de vida; y comparar dicha puntuación ajustada con al menos un valor umbral (TH).
