Captcha

I have added a captcha to my comments section as I was fed up getting moderation emails saying I had comments when I hardly ever do!

But this is no ordinary captcha… Oh no. It’s a reCAPTCHA!

Whats the difference? Well, along with providing an element of distinguishing between human and machine data entry, this captcha uses the entries to correct scanned books. By commenting on my blog you are helping to digitize books and ensure that the knowledge found within them will be preserved long after their pages decay, help to make it more openly available, and enable searchable databases of massive amounts of information to be formed!

How does it do this? Well basically you’ll notice that teh captcha gives two words to identify to check if you are human. One is pretty easy, and the other isn’t always so easy. The pretty easy one is the one that captcha knows, the other is a scanned word that the computer was unable to recognise. You’re humanity is verified with the known word and, if you are human, your reading ability is trusted with the other one! The unknown word is then paired up a bunch more times to ensure it’s accuracy.

As if that wasn’t enough, it has an audio recognition system for the visually impaired! So if you are having this read out to you by Microsoft Sam, fear not, you too can tell me I’m talking tripe and I should have my tongue cut out!

Funky huh? Improving the accuracy of digitised information while keping spam off Flat3d. Is there anything we can’t do?!
