Digital forensics is traditionally approached either as a computer science problem or as an investigative problem. In both cases, the goal is usually the same: attempt to locate discrete pieces of information that are probative. In the computer science approach, characteristics of the data are utilized to include or exclude objects, data or metadata. The investigative approach reviews the content of the evidence to interpret the data in the light of known facts and elements of the crime in order to determine probative information or information of lead value. This paper explores two literary theories, narrative theory and surrealism, for potential application to the digital forensic process. Narrative theory focuses on the “story” that is represented by text. At some level, a storage device may be viewed as a series of interweaving, possibly multi-dimensional, narratives. Furthermore, the narratives themselves, coupled with the metadata from the file system and applications, may form a meta-narrative. The literary theory of surrealism, the notion of disjointed elements, can be utilized to derive meaning from forensic evidence. This paper uses a technique known as surrealist games to illustrate the point.
