■ Paper Summary
This paper proposes a new method for multi-biometric continuous authentication called “Two-Dimensional Dynamic Fusion”. The key insight of this method is to calculate matching scores in two dimensions: the classifier and time. Based on this, the subset of classifiers is dynamically selected according to the authentication context, and matching scores are fused through multi-classifier fusion and multi-sample fusion. Experimental evaluation shows that this method achieves a better balance between resource usage and accuracy compared to existing fusion methods. In particular, by adopting multi-sample fusion, it achieves higher accuracy than existing methods with a similar computational load.
