Abstract
Actualmente el número de cámaras fotográficas en dispositivos móviles crece a un ritmo imparable. Asimismo la calidad y prestaciones de las mismas hacen que sean de uso común, desbancando poco a poco a las Cámaras fotográficas digitales. Este escenario produce que el análisis forense de este tipo de vídeos cobre especial importancia y sea necesario y útil en multitud de situaciones (pruebas en casos judiciales, espionaje industrial, privación de la libertad de prensa, pederastia, etc). En este trabajo se ha desarrollado una herramienta de ayuda al analista forense en el proceso de análisis de los metadatos de vídeos en formato MP4 con compresión H.264 y ACC. La herramienta permite diversas funciones complejas como son los distintos tipos de consultas avanzadas sobre la información de los metadatos de grandes conjuntos de vídeos o funciones de geoposicionamiento.
Currently the number of cameras in mobile devices is growing at an unstoppable rate. Also the quality and performance of the same make are in common use, edging slowly to Digital Cameras. This scenario causes the forensic analysis of such videos is particularly important and necessary and useful in many situations (evidence in court cases, industrial espionage, deprivation of freedom of the press, child abuse, etc.). In this work has been developed a tool to help the forensic analyst in the analysis process metadata of videos in MP4 format with H.264 compression and ACC The tool allows various complex functions such as different types of advanced queries on Exif metadata information of large sets of images or functions of geopositioning.
