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

A device for training a fake fingerprint detection model, the device comprising:

• a memory storing computer-executable instructions;
• and
• a processor for executing the instructions to:
• acquire a physical fake fingerprint image generated in a physical manner targeting a finger;
• provide generation constraints and a unique identification information to a training fingerprint image generation model;
• generate a training fingerprint image to be used for training the fake fingerprint detection model by using the training fingerprint image generation model;
• and
• train the fake fingerprint detection model using the physical fake fingerprint image and the training fingerprint image in a transfer learning manner or an ensemble learning manner,
• wherein the training fingerprint image generation model is trained to generate different training fingerprint images based on conditions included in the generation constraints.

A non-transitory computer-readable recording medium storing computer-executable instructions, wherein the computer-executable instructions, when executed by a processor, cause the processor to perform a method for training a fake fingerprint detection model, the method comprising:

• acquiring a physical fake fingerprint image generated in a physical manner targeting a finger;
• providing generation constraints and a unique identification information to a training fingerprint image generation model;
• generating a training fingerprint image to be used for training the fake fingerprint detection model by using the training fingerprint image generation model;
• and
• training the fake fingerprint detection model using the physical fake fingerprint image and the training fingerprint image in a transfer learning manner or an ensemble learning manner,
• wherein the training fingerprint image generation model is trained to generate different training fingerprint images based on conditions included in the generation constraints.
