Modeling the Impact of Biometric Security on Millennials’ Protection Motivation

Abstract

Security researchers and managers would like to know the best ways of introducing new innovations and motivating their use. This study applies Protection Motivation Theory to model the coping and threat appraisals that motivate Millennials, who are early technology adopters, to adopt or resist biometric security for system access. One hundred fifty-nine Millennials were given a hypothetical scenario in which system access would be enhanced by biometric security to strengthen user authentication. The authors model the results with PLS and find that Protection Motivation Theory provides a good explanation of the user’s perceptions of biometric security. The model suggests that the users’ protection motivation is influenced directly by the Perceived System Response Efficacy of the biometric system and indirectly by Perceived Effort Expectancy, Perceived Computer Self-Efficacy, Perceived Privacy Invasion and Perceived System Vulnerability. Implications and limitations of the model are discussed.
