Abstract: The present paper describes a system able to verify people starting from the image from the veins on the palm of the hand. The images are acquired with a commercial digital camera; they are processed by means of a series of techniques that improve the quality of the same to finally obtain the characteristics of interest from the veins. Starting from the segmented image of the veins 17 invariant moments are obtained with which it is possible by means of a neuronal network to verify the user's identity with a reliability of 99.3%. The average time that the system takes from the image acquisition upto the neuronal network results takes about 1.7 seconds.

Resumen: El presente artículo describe un sistema capaz de verificar personas a partir de la imagen de las venas de la mano. Las imágenes son adquiridas con una cámara digital comercial, son procesadas mediante una serie de técnicas que mejoran la calidad de las mismas para finalmente obtener las características de interés, las venas. A partir de la imagen segmentada de las venas se obtienen 17 momentos invariantes con los cuales es posible mediante una red neuronal verificar la identidad del usuario con una fiabilidad del 99.3%. El tiempo medio que se tarda el sistema desde la adquisición de la imagen hasta el resultado de la red neuronal es de 1.7 segundos.
