Reminder as ‘Watch-Out’: The Role of Privacy Salience at the Point of Interaction with Biometric Systems

Abstract

Biometrics users are concerned about privacy issues, while personal recognition methods are automated and easy to use. For users who want to protect their biometric information, practitioners need to take action in the public interest to better prevent users from leaking their biometric information in situations where the user interacts with the biometric system. This study explores how the user can perceive the consequences of registering biometric information through the Theory of Planned Behavior and attitude aspects. Sensitivity to potential consequences of the biological system was confirmed by the behavior and response observed by the subjects after using the biometric system. The sensitivity of the experimental group was found to be higher than that of the control group. Therefore, this study suggests that simple information presentation in system interaction can lead to more protective against privacy issue.
