Abstract: A device for determining an ID card includes an image input unit to acquire an initial image including an ID card image, an image pre-processing unit to generate a processed image by removing a remaining portion of the initial image except for the ID card image, and generate a first training image having a first resolution value and a second training image having a second resolution value, based on the processed image, an image determining unit to determine whether an identifying mark is present on the processed image, based on an artificial intelligence (AI) model based on a neural network trained by training data including the first training image and the second training image, and a model evaluating unit to calculate a plurality of parameters by using a determination result of the image determining unit and to evaluate the AI model based on the plurality of parameters.

Abstract: The inventive concept relates to a non-face-to-face authentication system, which strengthens security of face recognition at the same time as complementing the vulnerability of the authentication process through existing face recognition without undermining the convenience of the user.
