Digital Video Forensics: Review, Challenges, Parameters and Future Direction

Digital videos are recorded in everyday circumstances for a variety of reasons, including protection, preserving life-related experiences, and providing accurate proof. The growth of multimedia technology has led to share the digital videos on social media platforms. A variety of editing tools is used to alter the information presented in the digital videos with software. Consequently, it is more significant to secure the information in the digital videos. This work provides a review of digital video forensics. Firstly, digital video forensics has been introduced with its types firstly and after that, various kinds of digital video forgery like intra-frame forgery and inter-frame forgery are discussed. These forgery kinds have been further divided into different categories. The types of existing passive techniques have also been described for the detection of digital video forgeries in detail. Moreover, this paper delivers the new and innovative challenges within the digital video forensics. Besides, the evaluation parameters which are used in the existing techniques are discussed in detail. At last, future directions in the realm of digital video forensics are detailed in this paper.
