iSensor Lab

iSensor research, focused on behavioral anomaly detection in interpersonal, one-on-one, or team-based game environments, has implications for a broad range of fields related to cybersecurity as well as psychology, communication, information behavior, and human-computer interaction. Against the backdrop of social and cognitive psychology theories, iSensor research adopts a sociotechnical approach to understanding trustworthiness as a key component for countering computer-mediated deception, identity theft, fraud, and insider threats in the areas where trusted human computer interaction is critical. This research builds on Shuyuan’s dyadic attribution model to assess human trustworthiness in the identification of insider threat as a result of betrayal in the complex web of cyber trust.

Using online games, Shuyuan’s research constructs human-centric threats, crisis, and illicit behavioral scenarios to compile experimentally controlled simulations, which can process big data using a range of methodologies. From this research, she is working to develop an inference model for assessing trustworthiness and disposition in computer-mediated communications. One of the broader impacts of her sociotechnical study of human “sensors” (humans as predictive agents) is her work on predicting internal threats with high precision in a virtual organization. A primary challenge of this research is to uncover how anomalous behavior can be detected through language-action features and cues. As sociotechnical construct, the study of human “sensors” in online games serves two major aims: theorizing a framework for a dyadic attribution model, and modeling a computational approach for analogous, non-human intelligence learning systems, “i-Sensors.”

Future iSensor studies will support building sociotechnical systems (a “social firewall”) and social computational systems (non-human “sensors”) that aim to detect and predict changes in disposition and social inclinations of target individuals participating in collaborative and coordinated cyber-infrastructures. Unlike existing surveillance systems, “i-Sensors” do not generate online repositories (or logs) of individual’s private data, and thus protect personal privacy. Instead, i-Sensor creates attribution schema that tags online actors’ dispositional tendency for predictive behavioral analytics.
