Video data recovery from slack space of pre‐allocated video files
Journal of Forensic Sciences, EarlyView.Abstract The recovery of video evidence from dashboard cameras is often compromised by damage, file system errors, or circular recording mechanisms that overwrite older data. Traditional digital forensic techniques primarily focus on file carving and frame recovery from the unallocated area of storage media. However, this approach is often insufficient
