Completely Automated Public Turing test to tell Computers and Humans Apart
Ich denke Capchas machen uns alle verrückt. Daher habe ich mich sehr über die Aussage dieses Artikels gefreut: Why You Should Stop Using CAPTCHAs.
he reality is that for the vast majority of the sites that we build as web designers and developers, we don’t really have to worry about targeted attacks on our contact and registration forms. Using a CAPTCHA code on most sites is like using a Humvee to crack an egg. If you’re developing a high-profile site or security critical web app, then sure, perhaps a CAPTCHA is going to provide you the most protection. But even then, you should be weighing up the risks and usability trade-off and asking yourself if there is a more user-friendly alternative.
