Biological Feature Recognition Device and Method and Biological Feature Template Registration Method

摘要

A biological feature recognition apparatus, a biological feature recognition method, and a biological feature template registration method, wherein the biological feature recognition apparatus comprises: a sensor for sensing biological feature information; And acquiring biological feature information from the sensor, performing image preprocessing and feature extraction on the acquired biological feature information, and performing a feature comparison with the stored biological feature template to determine a biological feature recognition result Security chip. Since the whole process of biological feature recognition proceeds in an independent security chip, security can be greatly improved against existing logical isolation.
