    Abstract: A device generates parameters identifying selectively revealed un-obfuscated information associated with administering and assessing a Turing test. The device provides, to a client device, a challenge based on the parameters. The challenge directs the client device to selectively reveal the un-obfuscated information for presentation to a user associated with the client device. The device receives a response, to the challenge, from the client device and determines, based on the response and the parameters, whether the user associated with the client device is human.
