Abstract: Disclosed is a face verification method and apparatus. The method including analyzing a current frame of a verification image, determining a current frame state score of the verification image indicating whether the current frame is in a state predetermined as being appropriate for verification, determining whether the current frame state score satisfies a predetermined validity condition, and selectively, based on a result of the determining of whether the current frame state score satisfies the predetermined validity condition, extracting a feature from the current frame and performing verification by comparing a determined similarity between the extracted feature and a registered feature to a set verification threshold.

Abstract: An apparatus and method for detecting a fake fingerprint is disclosed. The apparatus may divide an input fingerprint image into blocks, determine an image quality assessment (IQA) value associated with each block, determine a confidence value based on the IQA values using a confidence determination model, and determine whether an input fingerprint in the input fingerprint image is a fake fingerprint based on the determined confidence value.

Abstract: A fingerprint recognition-based control method may include acquiring sensor data with a fingerprint sensor. The sensor data may be acquired by the fingerprint sensor in response to a contact between a physical object and a sensing area of the fingerprint sensor. The method may further include receiving an input through a first input receiver from among one or more input receivers. The first input receiver may be located in a vicinity of the fingerprint sensor. The method may further include verifying the sensor data to be an input fingerprint; and sensing a motion of the physical object based on the acquired sensor data and the received input, in response to a positive result of the verifying.
