Killing two birds with one Captcha
While following a link from Google News to The Hindu Newspaper I found a Captcha that does more than make you prove you are not a Bot. It makes you think.

Not only is the graphic… well… graphic, it is a social message that will be repeated and reinforced.
And it is cost effective from the advertising point of view. This is a perfect example of lateral thinking.
Getting people to prove that they are humans and not bots is a thankless task, and annoying to the users. I take my hat off to NLPCaptcha, the company that thought this one up.
And here is another example.
A visit to the NLPCatcha web site shows the application of this technology for advertisers and marketers.
The Captchas I saw on the Hindu web site where social in nature, but advertisers can use these Captchas. They come with some interesting benefits.
- Unlike banner ads, they must be focused on and interacted with.
- There is a foolproof way of counting views.
- It is a necessary security tool, but can provide a revenue stream for the web site.
- The user knows they need to interact and read the Captcha, so they do not resent the time spent. The advertiser gets guaranteed attention.
- Better user experience compared to the hated popups, and ignored banners.
This idea is a win-win situation for visitors, advertisers and web site owners.
There may be a down side, of course. Your message is being associated with an annoyance. But I think most users understand the need for verification And they are easier to use that the ones that require you to squint at blurry and twisted words!
