The recovery of a damaged or altered video file plays a vital role in searching for evidences to resolve a criminal case in digital forensics. Here, a frame-based recovery method for a corrupted video file has been proposed using the specifications of a codec that is used to encode the video data. The existing approaches try to recover a video file with the help of the file structure rather than frame structure. But the problem is that in the case where a target video file is severely fragmented or has a portion of video overwritten by other video content, video file recovery of existing approaches may fail. The proposed approach addresses how to extract video frames from a portion of the video to be restored as well as how to connect extracted video frames together according to the codec specifications. This paper proposes a technique to restore the video data on a frame basis from its corrupted versions where the video data …
