As we already know, there are more options besides audio and visual CAPTCHA that may be used to tell the difference between computers and humans. The open source project THaCAA – Telling Humans and Computers Apart Automatically represents another way to protect valuable web site resources without excluding anyone based on sensory factors such as hearing or sight.
Advocating full participation through equal accessibility.
This is really encouraging. It’s nondiscriminatory, and while it’s not as secure as the visual graphic, it’s much closer. Presumably it could be modified to suit whatever language the form is in.
Hi Darrell. I was just on that website and it looks pretty interesting. The only question I have is wouldn’t spambots be able to figure out which thing in each series doesn’t belong? I mean, if we smart humans can do it with absolutely no problem through process of elimination, wouldn’t the same be true of the spammers? I for one posted two comments on there. The first time I did so, I was asked to check all boxes that were mythical creatures. The second time I posted a comment, I was asked to check all boxes that had names of birds. I think this guy may actually be on to something but he just might not be there quite yet.
Different types of resources need varying levels of security. This tool may provide some security that goes far beyond nothing at all while falling short of some of the protections afforded by a full on CAPTCHA. Keep in mind that even some CAPTCHA implementations have been broken.
I just took a look at that site a few minutes ago. That was actually the first time I’ve been through an accessible captcha; and I got it right and was able to post a comment there, lol!
Sorry, visual captchas, but I won’t need any more sighted assistance to figure you out if you go the way of the dodo, lol, thanks to TextTHaCaa.
