Abstract
A device for biometric recognition, a method for biometric recognition, and a biometric template registration method are disclosed. The device comprises: a sensor for sensing information of a biometric feature; and a security chip for storing a template of the biometric feature, obtaining the information, performing image preprocessing and feature extraction on the obtained information, and comparing features with the stored template to determine a biometric recognition result. Since the whole biometric recognition process is executed in an independent security chip, the security is greatly improved compared with traditional logic isolation solutions.
