Abstract
Telling a human apart from a computer using a capacitance module may include receiving a request for human verification; determining a human-verification prompt; communicating the human-verification prompt using a prompting device in the capacitance module; detecting a response to the human-verification prompt using a user input sensor in the capacitance module; determining whether a human is operating the capacitance module based, in part, on the response detected with the user input detector; and returning a human verification result.
