Title:
GENERATING EVALUATION-MASK FOR MULTI-FACTOR AUTHENTICATION
Document Type and Number:
WIPO Patent Application WO/2022/127455
Kind Code:
A1
Abstract:
In an approach to improve multi-factor authentication methods generate an evaluation-mask over one or more modified items on a modified image created by a generative adversarial network (GAN). Further, methods create a scoring grid by comparing an original image with the modified image to identify different pixels between the original image and the modified image, and overlay the evaluation-mask over the identified different pixels on the modified image. Methods display the modified image as a multi-factor authentication prompt to a user and prompt the user to provide a response that identifies one or more modifications in the modified image. Additionally, methods compute an evaluation score based on a comparison of the response from the user with the evaluation-mask, to validate the response from the user, and authenticate and grant the user access to data or other resources if the evaluation score meets or exceeds a predetermined threshold.
