“…Some researches have been carried in the field of file fragment classification of video file formats [1][2][3]. There are some publicly available datasets for file fragments of various file formats [4][5][6].…”
Objectives: File fragment classification of video file formats is a topic of interest in network forensics. There are some publicly available datasets for file fragments of various file types such as textual, audio, and image file formats. However, there is no public dataset for file fragments of video file formats. So, in order to evaluate and compare the performance of the classification methods, a challenge is the need to have such datasets.

“…Uno de los primeros trabajos donde se realiza un análisis detallado de las estructuras de los vídeos es [19] donde se analizan en detalle las secuencias de vídeo AVI y MP4 (MOV, 3GP, MP4) de teléfonos móviles y cámaras digitales. Uno de los principales resultados que se obtienen es que los vídeos de cámaras digitales y teléfonos móviles suelen emplear diferentes formatos de contenedores y codecs de compresión.…”

“…La Tabla II muestra el output que se obtiene tras la extracción de losátomos. El primerátomo es "fytp" tal y como se indica en las especificaciones de [19]. Como losátomos se organizan jerárquicamente (ie./moov/), a su vez tienenátomos hijos (ie./moov/trak) y etiquetas (ie./moov/mvhd/tkhd/flags) que a su vez contienen valores (ie./moov/mvhd/tkhd/version,value:0).…”

The advancement of technology has led to better and improved service in mobile communication networks. Smartphones are being used by people for social networking, conducting business transactions as well as committing crime. Anti-Forensic compromises the availability of evidence to the forensic process causing problems to the investigator. The aim of this paper is to provide a solution to the anti-forensic technique of steganography by designing and implementation of an application that will scan, hash and analyze for any hidden information on an image, video or audio file on an android device and collect data for digital profiling or investigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
