Claim Text:
1. A fingerprint-recognition method, applied to an electronic device, the electronic device comprising a storage unit, a Trust-Zone comprising a first processing unit and a Security Element comprising a second processing unit, the fingerprint-recognition method comprising: transmitting first part registered fingerprint datasets to the first processing unit by the second processing unit; obtaining second part registered fingerprint datasets from the storage unit by the first processing unit; obtaining complete registered fingerprint datasets according to the first part registered fingerprint datasets and the second part registered fingerprint datasets; obtaining a verification fingerprint image; transmitting the verification fingerprint image to the first processing unit; generating verification fingerprint data according to the verification fingerprint image by the first processing unit; dividing the verification fingerprint data into first part verification fingerprint data and second part verification fingerprint data; comparing the verification fingerprint data with the complete registered fingerprint datasets to generate a first matching result and matching information by the first processing unit; transmitting a first part of the first matching result, the first part verification fingerprint data and the matching information from the first processing unit to the second processing unit; comparing the first part verification fingerprint data with one of the first part registered fingerprint datasets to generate a second matching result by the second processing unit according to the matching information; and comparing the first part of the first matching result and the second matching result so as to verify the verification fingerprint data by the second processing unit.
