Human verification by contextually iconic visual public turing test

摘要

There is provided a system and method for human verification by a contextually iconic visual public Turing test. There is provided a method comprising receiving a request to verify whether a client is human controlled, selecting, by contextual criteria, a plurality of images each having one or more associated tags from a database, generating a challenge question and a corresponding answer set based on associated tags of a subset of the plurality of images, presenting the plurality of images and the challenge question to the client, receiving a submission to the challenge question from the client, and responding to the request by verifying whether the submission is contained in the answer set to determine whether the client is human controlled. The contextual criteria may comprise subject matter, branding, or intended audience of a content provider sending the request, thereby facilitating human responses while deterring automated systems.

1. A method for human verification comprising a contextually iconic visual public Turing test, the method comprising:
receiving a request to verify whether a client is human controlled; selecting, by contextual criteria, a plurality of images each having one or more associated tags from a database; generating a challenge question and a corresponding answer set based on associated tags of a subset of the plurality of images, wherein the challenge question includes an animated tutorial with visual cues; presenting the plurality of images and the challenge question to the client; receiving an answer to the challenge question or a rephrase indication from the client; if receiving the answer from the client, responding to the request by verifying whether the answer is contained in the answer set to determine whether the client is human controlled; if receiving the rephrase indication from the client, generating a rephrased challenge question having the corresponding answer set, wherein the rephrased challenge question includes the animated tutorial with the visual cues; and presenting the rephrased challenge question to the client; wherein the challenge question is more specific than the rephrased challenge question, and wherein the rephrased challenge question is more general than the challenge question.
