IMAGE RECOGNITION REVERSE TUNING TEST SYSTEM

Abstract:

Computer implemented methods and systems are provided for controlling access to one or more computational resources by discriminating between a human user or an automated process. An example system comprises one or more computer processors operating in conjunction with computer memory and data storage to render a set of question images including at least two images having one or more inter-image visually ascertainable relationships, and at least one image having one or more intra-image visually ascertainable relationships, the inter-image visually ascertainable relationships and the intra-image visually ascertainable relationships having one overlapping visually ascertainable relationship. The system further renders a set of candidate answer images including at least an incorrect subset of images and a correct subset of images portraying the overlapping visually ascertainable relationship, and determines whether to grant access to the one or more computational resources based upon a user selection from the set of candidate answer images.
