Information Disclosure to Biometric E-gates: The Roles of Perceived Security, Benefits, and Emotions

Biometric authentication systems, such as electronic (e-)gates are increasingly important in air travel because of the growing traveler flows and security challenges. Such systems allow for accurate authentication and the improvement of the air travel experience, while enhancing the security of the overall travel system. To authenticate, the travelers are required to disclose biometric information. Grounded in equity and emotion theories and using data from 511 US air travelers, this study examined several antecedents of biometric information disclosure to e-gates. It was found that security perceptions and benefits of disclosure had strong impacts on disclosure, while positive and negative emotions influenced travelers’ perceptions of security.
