Abstract

The invention relates to a method of a fingerprint sensing system (101) of enabling suppressing impairment data (120) present in an image captured by a fingerprint sensor (102) of the fingerprint sensing system, and a fingerprint sensing system (101) performing the method.

Description

technical field [0001] The present invention relates to a method of a fingerprint sensing system for suppressing the presence of impaired data in an image captured by a fingerprint sensor of the fingerprint sensing system and a fingerprint sensing system performing the method. Background technique [0002] Electronic devices such as smartphones, laptops, remote controls, tablets, smart cards, etc. may use fingerprint identification, for example, to allow a user to access the device, to authorize transactions performed using the electronic device, or to authorize the user to Access services. [0003] Therefore, an electronic device (eg, a smartphone) is equipped with a fingerprint sensor on which a user places her finger so that the sensor captures an image of the fingerprint and compares the recorded fingerprint with a pre-stored authenticated fingerprint template. If the recorded fingerprint matches a pre-stored template, the user is authenticated and the smartphone will p...
