Abstract

A method and apparatus for processing biometric information in an electronic device including a processor that operates at a normal mode or at a secure mode, the method comprising, detecting a biometric input event from a biometric sensor module at normal mode, creating biometric data based on sensed data from the biometric sensor module at the secure mode, performing biometric registration or biometric authentication based on the created biometric data at the secure mode, and providing result information of biometric registration or biometric authentication at the normal mode.

Claims17

Dependent claims

A method for processing biometric information in an electronic device, the method comprising:

detecting, by at least one processor in a normal mode operating under a first operating system, a biometric input event from a biometric sensor module;
switching, by the at least one processor, to a secure mode operating under a second operating system, after the detection of the biometric input event, the second operating system being a secure operating system;
creating, by the at least one processor in the secure mode, in response to the biometric input event, biometric data based on sensed data from the biometric sensor module;
performing, by the at least one processor in the secure mode, biometric registration or biometric authentication based on the created biometric data;
providing, by the at least one processor in the secure mode, result information of the biometric registration or the biometric authentication;
and
switching, by the at least one processor, from the secure mode to the normal mode, after providing the result information.

4 more elements

An electronic device for processing biometric information, the electronic device comprising:

a biometric sensor module configured to sense a biometric object;
and
at least one processor configured to:
detect a biometric input event from the biometric sensor module, when in a normal mode operating under a first operating system;
switch to a secure mode operating under a second operating system in response to the detection of the biometric input event, the second operating system being a secure operating system;
create, in the secure mode, in response to the biometric input event, biometric data based on sensed data from the biometric sensor module;
perform, in the secure mode, biometric registration or biometric authentication based on the created biometric data;
and
provide, in the secure mode, result information of biometric registration or biometric authentication at the normal mode;
and
switch from the secure mode to the normal mode after providing the result information.
