Computer-Assisted Reasoning in Digital Forensics

Eoghan Casey, Defense Cyber Crime Institute (DC3/DCCI)

The primary challenge in digital forensics today is uncovering not the right answer, but the right question. As in any scientific discipline, the formation of viable hypotheses that ultimately uncover meaning in available evidence is a central problem in digital forensics. Such hypothesis formation, based on intuition and experience, involves an underlying mental process that can be substantially aided by computers. This seminar delves into the cognitive science of investigative reasoning, and how research in artificial intelligence can help humans find the right questions in large quantities of data. The implications of this work for digital identity and privacy, as well as its potential uses in other areas, such as medical diagnosis and virtual learning environments, are also discussed.
