Using the technique on photos can reassemble photos even if some of the image data is missing, resulting in a picture that has a band missing from it. The method can create approximate headers for image files as well, which results in gathering and reassembling enough pieces to recreate a version of the image that might not be as sharp as the original, Memon says.
New research adapts this technique to other file formats such as .doc files. It looks at the content in file fragments and classifies it based on syntactical similarities. This is akin to sorting a box of jigsaw puzzle pieces that contains the pieces for many puzzles so that all the pieces from each puzzle are put in separate boxes, Memon says. Each puzzle can then be assembled based on the shapes of the pieces and the image fragment printed on them.
