Abstract: Disclosed is a liveness test method and apparatus. A liveness test apparatus determines a pre-liveness score based on a plurality of sub-images acquired from an input image, determines a post-liveness score based on a recognition model for recognizing an object included in the input image, and determines a liveness of the object based on any one or any combination of the pre-liveness score and the post-liveness score.

Abstract: A fingerprint verification method and a fingerprint verification apparatus performing the fingerprint verification method are disclosed. The fingerprint verification apparatus determines a first similarity between a query fingerprint image and each of registered fingerprint images, selects a target registered fingerprint image group from registered fingerprint image groups based on the first similarity, determines a second similarity between the query fingerprint image and each of registered fingerprint images in the target registered fingerprint image group based on matching relationship information between the registered fingerprint images in the target registered fingerprint image group, and determines whether fingerprint verification of the query fingerprint image is successful based on the second similarity.

Abstract: A surface treatment apparatus and a surface treatment system having the same are disclosed. The surface treatment apparatus includes a process chamber in which the surface treatment process is conducted, a plasma generator for generating process radicals as a plasma state for the surface treatment process, the plasma generator being positioned outside of the process chamber and connected to the process chamber by a supply duct, a heat exchanger arranged on the supply duct and cooling down temperature of the process radicals passing through the supply duct and a flow controller controlling the process radicals to flow out of the process chamber. The flow controller is connected to a discharge duct through which the process radicals are discharged outside the process chamber. The plasma surface treatment process is conducted to the package structure having minute mounting gap without the damages to the IC chip and the board.
