Abstract:
Vital-sign-based biometric authentication enables continuous and unobtrusive identity verification in healthcare using signals like ECG and PPG. To support systematic analysis of diverse application scenarios, this paper presents a taxonomy comprising 16 dimensions and 46 characteristics. Developed iteratively through literature review and use case classification, the taxonomy enables clear comparison and design guidance for biometric systems. The result is a practical framework for researchers and developers to evaluate and apply biometric authentication technologies across various healthcare contexts.
