Introducing media forensics
Media forensics can be defined as the process of locating, analyzing, and extracting meaningful metadata from any kind of multimedia object, such as an image or a video. Modern iOS devices such as the iPhone 13 have huge storage capacities (the base model has 128 GB of storage), and this allows them to potentially store tens of thousands of media files. Each of these is linked to particular metadata that may give an investigator a lot more information than the file itself.
Although it may be tempting to think of multimedia assets merely as photos or videos, iOS devices, in reality, handle a lot more than that; the following is a list of common media assets that can be found on an iOS device:
- Camera roll photos, videos, and live photos
- Saved photos and videos
- Screenshots
- Audio recordings and music
- Media files received from third-party apps (such as WhatsApp and Telegram)
- Streamed content
