الملخصIn recent years, many digital devices have been equipped with a video camera that allows videos to be recorded in good quality, free of charge and without restrictions. Concurrently, the widespread use of digital videos via web-based multimedia systems and mobile smartphone applications such as YouTube, Facebook, Twitter and WhatsApp is becoming increasing important. However, security challenges have emerged and are spreading worldwide. These issues may lead to serious problems, particularly in situations where video is a key part of decision-making in crimes, including movie piracy and child pornography. Thus, to increase the trustworthiness of using digital video in daily life, copyright protection and video authentication must be used. Although source camera identification based on digital images has attracted many researchers' attention, less research has been performed on the forensic analysis of videos due to certain challenges, such as compression, stabilization, scaling, and cropping, as well as differences between frame types that can occur when a video is stored in digital devices. Thus, there are insufficient large standard digital video databases and updated databases with new devices based on new technologies. The goal of this paper is to offer an inclusive overview of what has been done over the last decade in the field of source video identification by examining existing techniques, such as photo response nonuniformity (PRNU) and machine learning approaches, and describing some popular video databases.
راعي المشروعFFmpeg 1: FFmpeg is one of the most popular multimedia frameworks that can decode, encode, transcode, mux, demux, stream, filter and play anything that humans and machines have created. From ancient to modern formats, the software supports different frameworks: Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. FFmpeg is used to re-encode original flatfield videos to have the same resolution as natural videos if the resolution changes. A software package included in ffmpeg (ffprobe) is used to extract video frames (type, frame rate, bit rate, resolution, etc.) and save them in an uncompressed format. Additionally, to extract I, B, and P frames and motion vectors, these tools can be used.This publication was made possible by NPRP grant # NPRP12S-0312-190332 from Qatar National Research Fund (a member of Qatar Foundation).
