iOS devices generally allow users to synch their images (pictures) and video files using iTunes between Apple products (e.g. an iPhone and a MacBook Pro). Recovering deleted images, particularly in a forensically sound manner, from iOS devices can be an expensive and challenging exercise (due to the hierarchical encrypted file system, etc). In this paper, we propose an operational technique that allows digital forensic practitioners to recover deleted image files by referring to iOS journaling file system. Using an iPhone as a case study, we then conduct a forensic analysis to validate our proposed technique.
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.
