Abstract

Methods and systems are described herein for facilitating token use authentication for access tokens using stochastic images. The system may detect an authentication request to authenticate use of an access token. The access token may be associated with a first image previously displayed to an authenticated user of the access token. The system may retrieve the first image previously displayed to the authenticated user and input parameters previously used to generate the first image. The system may obtain, from a stochastic machine learning model based on the input parameters, a second image different from the first image. The system may generate, for display, an image set including the first image and the second image and may receive a selection of the first image from the image set. The system may then grant the authentication request based on the selection of the first image.

Dependent claims

A system for facilitating token use authentication for an access token using stochastic-model-derived images generated from identical input parameters previously used to generate a valid stochastic image stored in association with the access token, the system comprising:

one or more processors and one or more non-transitory computer-readable media having computer-executable instructions stored thereon, the computer-executable instructions, when executed by the one or more processors, causing operations comprising:
detecting an authentication request to authenticate use of a network access token to perform a network operation, the network access token being associated with a first stochastic image previously displayed to an authenticated user of the network access token;
in response to detecting the authentication request, retrieving, from storage, (i) the first stochastic image previously displayed to the authenticated user and (ii) image generation parameters previously used to generate the first stochastic image, the image generation parameters corresponding to token data associated with the network access token;
providing the image generation parameters, previously used to generate the first stochastic image, to a stochastic machine learning model to obtain a second stochastic image, the second stochastic image being different from the first stochastic image despite the image generation parameters used to obtain the second stochastic image being identical to the image generation parameters previously used to generate the first stochastic image;
generating, for display, (i) an authentication image set comprising the first stochastic image and the second stochastic image and (ii) instructions to select an image that has been previously displayed to the authenticated user;
and
in response to a user image selection from the authentication image set, generating an authentication response to the authentication request such that the authentication response comprises (i) granting the authentication request in response to a first user selection of the first stochastic image and (ii) declining the authentication request in response to a second user selection of the second stochastic image.

One or more non-transitory, computer-readable media storing instructions that when executed by one or more processors cause the one or more processors to perform operations comprising:

detecting an authentication request to authenticate use of a token, the token being associated with a first image previously displayed to an authenticated user of the token;
retrieving, from storage, a stored representation of at least a portion of the first image previously displayed to the authenticated user, the first image being previously generated via a stochastic machine learning model using token data associated with the token as input parameters to the stochastic machine learning model;
providing the input parameters to the stochastic machine learning model to obtain a second image different from the first image;
generating, for display, an image set comprising the first image and the second image;
receiving a selection of the first image from the image set;
receiving an image representation related to the token in connection with the authentication request and the selection of the first image;
and
generating an authentication response to the authentication request based on (i) the stored representation of at least the portion of the first image and (ii) the image representation of the authentication request.
