As the World Wide Web grows, the number and variety of deceptive attacks targeting online consumers likewise increases. Extant research has examined online deception from an information processing perspective, that is, how users process information when they encounter deceptive attacks. However, users’ ability to process information is based on what the users are thinking or their frame of mind while engaged with that information. Frame of mind has not been well studied in the security domain. This study proposes the effect of users’ frame of mind on their attitude towards online deception and their actual deception detection behaviour. Specifically, we propose that human information needs and the framing (positive or negative) of important information such as warnings are significant components of users’ frames of mind that impact their vulnerability to online attacks. We conclude the paper by discussing in detail the experimental setup and expected contributions from the analysis.
