Captcha is an online gateway forcing the user to perform a simple task to prove he is human (not a machine). We have reinvented this tool in a meaninful way. In our new Amnesty Captcha users could prove their humanity in a deeper meaning and, instead of performing an irritating, mechanical task, sign one of Amnesty International’s human rights related online petitions. Because what really differentiates humans from machines is our ability to feel.
