Classification: CPC G | IPC G

Claim 9:
10. A system for user authentication using original and modified images, comprising:
a processor and a memory configured to provide computer program instructions to the processor, the program instructions executable by the processor to cause the processor to:
an image receiving component for receiving an original image for a user;
receive an unaltered original image for a user, wherein the unaltered original image has not been previously shared;
use a pre-trained Convolutional Neural Network (CNN) model to extract one or more image features of the unaltered original image;
feed the one or more extracted image features into a Generative Adversarial Network (GAN) image generator to modify the one or more extracted image features to generate a modified image; and
supply an image set of unaltered original and modified images to an authentication component for authenticating the user based on recognition of a presented unaltered original image or presented modified image.
