Abstract
Certain embodiments provide a biometric recognition apparatus and a method for lowering false recognition rate of biometric information in an electronic device adopting biometric recognition technology. In doing so, the electronic device may store first feature values extracted at M-ary feature points from owner biometric information, and additionally store auxiliary biometric information from a biometric information stored in one or more memories or an external server. The electronic device may perform biometric recognition on input biometric information using the first feature values and second feature values extracted from the biometric information additionally stored.
Claims20
An electronic device comprising:
- one or more memories;
- and
- at least one processor for accessing the one or more memories,
- wherein at least one of the one or more memories stores instructions, when executed, causing the at least one processor to:
- determine M-ary feature points to obtain first feature values from owner biometric information, and
- identify auxiliary biometric information from a biometric information stored in at least one of the one or more memories or an external server,
- wherein the auxiliary biometric information has similar feature values with the owner biometric information at the M-ary feature points.
A biometric authentication method in an electronic device, comprising:
- determining M-ary feature points to obtain first feature values from owner biometric information;
- identifying auxiliary biometric information from a biometric information stored in at least one of one or more memories or an external server;
- and
- performing biometric authentication on input biometric information based on the owner biometric information and the auxiliary biometric information,
- wherein the auxiliary biometric information has similar feature values with the owner biometric information at the M-ary feature points.
