Classification: CPC G | IPC G

Claim 0:
1. A method performed by a fingerprint sensing system of verifying that setting data of a fingerprint sensor of the fingerprint sensing system has not been modified, comprising:
blocking, upon receiving a fingerprint image capture command, access to the fingerprint sensor setting data held in a storage of the fingerprint sensing system;
subsequent to blocking access to the fingerprint sensor setting data, acquiring, from the fingerprint sensor, a representation of the fingerprint sensor setting data to be utilized upon capturing a fingerprint image;
verifying from the acquired representation if the fingerprint sensor setting data corresponds to fingerprint sensor setting data that previously was written to the storage; and
when a captured image is read out, unblocking access to the fingerprint sensor setting data held in the storage of the fingerprint sensing system.
