Method and apparatus for fake fingerprints generation, and training method of artificial intelligence for identifying fake fingerprints

A method for training a fake fingerprint detection model, performed by a training device for an artificial intelligence model, the method comprising:

• acquiring a fingerprint image targeting a fingerprint of a finger;
• extracting unique identification information of a fingerprint from the fingerprint image;
• providing the unique identification information and generation constraints to a training fingerprint image generating model, wherein the training fingerprint image generation model is trained to generate different training fingerprint images based on conditions included in the generation constraints;
• generating a training fingerprint image to be used for training a fake fingerprint detection model by using the training fingerprint image generation model;
• and
• training the fake fingerprint detection model using at least one of the training fingerprint image and an image obtained from a real fingerprint.

A fingerprint generation device comprising:

• a memory storing computer-executable instructions;
• and
• a processor for executing the instructions to:
• acquire a fingerprint image targeting a fingerprint of a finger;
• extract unique identification information of a fingerprint from the fingerprint image;
• and
• provide the unique identification information and generation constraints to a training fingerprint image generation model to obtain a training fingerprint image to be used for training a fake fingerprint detection model by using the training fingerprint image generation model, wherein the training fingerprint image generation model is trained to generate different training fingerprint images based on conditions included in the generation constraints.
