Title:
BIOMETRIC RECOGNITION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/191547
Kind Code:
A1
Abstract:
Disclosed are a biometric recognition method and apparatus, belonging to the technical field of computers. The method comprises: after acquiring, under a TEE, a biometric image, extracting, under the TEE, biometric feature data from the biometric image; and then matching, in an SE, all of or part of the biometric feature data with a biometric feature template to obtain a biometric recognition result. In the present application, since the security level of an SE is higher than a TEE, the biometric recognition function reaches a high security level. In addition, since the calculation of template matching of biometric feature data is not complicated, and the processing pressure of the SE is relatively small, it can be ensured that the template matching speed is relatively high, and thus, it can be ensured that the biometric recognition speed is relatively high. In this way, by means of the present application, where the delay is only increased slightly and biometric recognition performance is not affected, biometric recognition achieves protection with a high security level, so that the security of biometric recognition can be improved.
