SYSTEMS AND METHODS FOR USER AUTHENTICATION

摘要

Systems, methods, and non-transitory computer-readable media can determine at least one operation that causes a challenge-response test to be activated for authenticating a user. A first set of content items that each have a threshold similarity to a query content item can be determined. A second set of content items that each have a threshold dissimilarity to the query content item can be determined. The challenge-response test can be provided for display to the user. The challenge-response test presents a group of content items including the first set of content items and the second set of content items.

1. A computer-implemented method comprising:
determining, by a computing system, at least one operation that causes a challenge-response test to be activated for authenticating a user; determining, by the computing system, a first set of content items that each have a threshold similarity to a query content item; determining, by the computing system, a second set of content items that each have a threshold dissimilarity to the query content item; and providing, by the computing system, the challenge-response test for display to the user, wherein the challenge-response test presents a group of content items including the first set of content items and the second set of content items.
