The first question corresponds to a first cognitive level and includes at least one image selected from a set of images. The approach computes a confidence value of a first answer received from the requestor responding to the first question. In response to determining that the confidence value is below a confidence threshold, the approach provides a second question to the requestor corresponding to a second cognitive level that is increased from the first cognitive level. The approach grants access to the requestor in response to determining that a second answer received from the requestor responding to the second question is a correct answer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detector for online user verification","description":"An approach is provided in which the approach provides a first question to a requestor requesting access to a resource.
