Biometric authentication has become ubiquitous and profoundly impacts decision-making for both individuals and firms. Despite its extensive implementation, there is a discernible knowledge gap in understanding the nuanced influence of biometric characteristics on user security behaviors. To advance this line of research, we embrace the controversial information technology framework to delve into the juxtaposed nature of biometric characteristics, wherein they concurrently yield benefits and raise concerns that manifest in opposing effects on users' switching behavior. Adopting a sequential mixed methods approach, we first conducted semi-structured interviews that uncovered three key biometric characteristics and identified two benefits and two concerns associated with them. A follow-up survey was conducted to explore the interplay between each identified construct. The results emphasize the pivotal role of biometric characteristics in shaping user security behavior. Our research contributes to theoretical understanding by scrutinizing user behaviors vis-à-vis biometric authentication through a controversial IT perspective.

揭示生物识别特征对用户安全行为的并列影响：有争议的信息技术视角


生物识别认证已变得无处不在，并深刻影响个人和公司的决策。尽管得到了广泛的实施，但在理解生物识别特征对用户安全行为的细微影响方面仍存在明显的知识差距。为了推进这一研究方向，我们采用有争议的信息技术框架来深入研究生物识别特征的并置性质，其中它们同时产生好处并引起对用户转换行为的相反影响的担忧。采用顺序混合方法，我们首先进行了半结构化访谈，揭示了三个关键的生物识别特征，并确定了与之相关的两个好处和两个问题。进行了后续调查，以探索每个已确定的结构之间的相互作用。结果强调了生物识别特征在塑造用户安全行为中的关键作用。我们的研究通过有争议的 IT 视角审视用户相对于生物识别身份验证的行为，有助于理论理解。
