A quick follow up to last month’s blog post where we discussed CAPTCHAs, how they work as well as benefits and drawbacks of using them.

It appears that YUNiTi, a social networking site, has been working on a new style of CAPTCHA based on 3D images. Three 3D images are shown and the user has to pick the correct option from a list provided (see the screenshot below for more information or try it out yourself on the registration page)

Of course, this seems like a great idea for us humans who are required to sort through the often complex and hard to read CAPTCHAs, and I’m sure it will keep the bots out for a while until they develop the technology to get through this new style.

However, Dog Cow raised an interesting point that I hadn’t addressed in my previous blog about CAPTCHAs; What about those that are hard of sight and aren’t able to read or even see the CAPTCHA? This new style doesn’t solve that fundamental issue, and it won’t be solved until we have a situation where we no longer need CAPTCHAs.

An interesting debate, as always let us know what you think by commenting below.
