| dc.description.abstract | La transparencia, la calidad y el tiempo de procesamiento son algunos de los parámetros más importantes en los métodos esteganográficos. Este documento propone un método de ocultamiento de imágenes a escala de grises en imágenes a color, basado en la modificación de píxeles en el dominio del espacio. Se modificó el método de ocultamiento de píxeles por bloque (BPHM) con resultados en términos de transparencia de la imagen stego (tanto a nivel cualitativo como cuantitativo) y de la calidad de la imagen secreta recuperada, mejores que el método original. | spa |

| dc.description.abstractenglish | The transparency, quality and processing time are some of the important parameters in the steganographic methods, this paper proposed a hiding method of gray scale images in color images using based on the modification of pixels in spatial domain. The pixel in block hiding method was modified with results in terms of transparency of stego image (both qualitative and quantitative) and quality of the secret image retrieved, better than the original method. | eng |
