Abstract
Methods, apparatus, and products are disclosed for user authorization using an automated Turing Test that include: selecting, by an automated Turing Test module, a challenge token, the challenge token including a challenge key; repeatedly at an Automated Turing Test pace: selecting, by the Automated Turing Test module, a portion of the challenge token in dependence upon predetermined selection criteria, and revealing, by Automated Turing Test module, only the selected portion of the challenge token to a user; receiving, by the Automated Turing Test module from the user, a user response; determining, by the Automated Turing Test module, whether the user response matches the challenge key; and authorizing, by the Automated Turing Test module, the user to access a resource if the user response matches the challenge key.
