Re: [IxDA Discuss] Verifying a user is human
Thanks for all the input guys. You've given me some great ideas - which is exactly what I was hoping to get.

[IxDA Discuss] Verifying a user is human
I am in the process of designing a support forum for a software product. The goal is to make it as easy as possible to ask a question. Ideally I'd like to do away with the need to login all together, but it also needs to be Spam resistant. I've looked a little into the CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) method, better known as the distorted text method, but questions have been raised about both its accessibility and effectiveness. There is the option of sending an activation email. However, this adds several steps for the user and is not without its own issues (Spam filters etc.) Does anyone have any thoughts on the best method to confirm a user is human? Maybe a third option I haven't thought of?

First, I'm amazed you know what CAPTCHA stands for. :) Second, this is a problem that really bugs me too, so I'm interested in ideas. How about something like a 2+2 = ? followed by a dropdown? Dropdowns have low usability, so maybe entering the answer into an input field would be better. I've seen this type of solution used before, and while it requires more work for the user, it's often less work than trying to interpret the letters in a CAPTCHA system. -r- *Come to IxDA Interaction08 | Savannah* February 8-10, 2008 in Savannah, GA, USA Register today: http://interaction08.ixda.org/ Welcome to the Interaction Design Association (IxDA)!

Re: [IxDA Discuss] Verifying a user is human
How about something like a 2+2 = ? followed by a dropdown? 2+2 in text would probably be easy to parse. Make the 2+2 an image and it would probably do pretty well for next year or two. The deterrent against the computer (image deciphering) is still being used but it's more natural since it's a question format than a copy this task. I have failed the CAPTCHA tests more than once or twice and it's quite dehumanizing. -Dan *Come to IxDA Interaction08 | Savannah* February 8-10, 2008 in Savannah, GA, USA Register today: http://interaction08.ixda.org/ Welcome to the Interaction Design Association (IxDA)!

Re: [IxDA Discuss] Verifying a user is human
Chris asked: Does anyone have any thoughts on the best method to confirm a user is human? Seems like this made the rounds on the blog circuit a few weeks ago: You're in a desert, walking along in the sand when all of a sudden you look down and see a tortoise. You reach down and you flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over but it can't. Not without your help. Do you flip it back over? Type your answer below. IIRC there was an abbreviated test that simply asked: What color is an orange? On my own blog I've found it pretty effective to simply block any comments with more than a certain number of URLs in the body. Also, the Akismet spam filter on Wordpress has been remarkably efficient. It's filtered out hundreds of spam comments with no false positives and only one false negative since I started using it. I've never looked in to how it works but it doesn't require anyone to prove they're human. // jeff . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Re: [IxDA Discuss] Verifying a user is human
Hi, CAPTCHA done right is very effective, and can be accessible as well. I suggest taking a look at the reCAPTCHA project (http://recaptcha.net/), they have an audio version available as well, and it contributes back to the Internet Archive project, always a worthy cause. There was just a great article on a blog about CAPTCHA's, but I can't remember which one right now.. when I find it I'll make sure to send it back to the list. Matt.

[IxDA Discuss] Verifying a user is human
Chris, I'd suggest you create your own test instead of using a standard CAPTCHA. The simplest way to resist spambots is to give them a question they haven't seen on several thousand other sites - and you can easily make it accessible for humans if you don't have to worry about fooling the machines. Take a look at http://almaer.com/blog/logic-based-captcha-to-beat-the-blog-spam-bots for a discussion of some possible questions at the end of the post.

Re: [IxDA Discuss] Verifying a user is human
Also, if it's a support forum for a software application, you could provide the key for submitting support requests inside the software, or the ability to do so (in the form of a button or link). Folks who come to the site outside the software may have to suffer a login, but those coming from your software would have a free ride, so to speak.

Re: [IxDA Discuss] Verifying a user is human
I've seen this type of solution used before, and while it requires more work for the user, it's often less work than trying to interpret the letters in a CAPTCHA system. reCAPTCHA is a nice CAPTCHA implementation that uses (mostly) actual words for verification. And it's a nice way to help with the digitizing of books as well. http://recaptcha.net/ It also has some accessibility features built in. But, as with all CAPTCHAs, it can be circumvented in a manner as described here: http://en.wikipedia.org/wiki/Captcha#Human_solvers The math equation solution is subject to this hack as well. I think the only way you can absolutely verify that there's a non-nefarious human on the other end is via biometrics, and I'm guessing that that won't be a feasible option. jason *Come to IxDA Interaction08 | Savannah* February 8-10, 2008 in Savannah, GA, USA Register today: http://interaction08.ixda.org/ Welcome to the Interaction Design Association (IxDA)!
