■ 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.

■ Paper Accepted
DZ Security®‘s core technology, Background Authentication, was recognized at the International Joint Conference on Biometrics (IJCB 2023), organized by the Institute of Electrical and Electronics Engineers (IEEE), where a research paper on the technology was accepted for publication.
IJCB is the most authoritative biometric conference in the world. The acceptance of our paper indicates that Background Authentication has received the highest evaluation globally for its security and uniqueness.
Background Authentication is a authentication technology that allows users to utilize it without any burden, and cannot be impersonated by anyone. We will continue to develop this technology to become a global standard for authentication in the future.
