Towards AI forensics: Did the artificial intelligence system do it?

Abstract

Artificial intelligence (AI) makes decisions impacting our daily lives in an increasingly autonomous manner. Their actions might cause accidents, harm, or, more generally, violate regulations. Determining whether an AI caused a specific event and, if so, what triggered the AI’s action, are key forensic questions. We provide a conceptualization of the problems and strategies for forensic investigation. We focus on AI that is potentially “malicious by design” and gray box analysis. Our evaluation using convolutional neural networks illustrates challenges and ideas for identifying malicious AI.
