CAPTCHA—I bet you use it and don’t know it. A captcha is that box with the squiggle words you need to enter to have access to a site. It helps decide if the person wanting to access the site is a human or a computer bot (spam bot).
One wonders if at what point a programmer will figure out how to have a computer read these words and bypass this safeguard.
If you notice the word or two a captcha site asks you enter, the words are wavy and may have a line thought them.
CAPTCHA is actually an acronym for Comply Automated Pubic Turing test to Tell Humans and Computers Apart. In 2000, Luis von Ahn, Manuel Blum, Nicholas Hopper and John Langford of Carnegie Mellon University coined the term.
ALSO: I received and email from Elan at a company called Adscaptcha after I wrote this post. He seems to have a company that created unique captcha tool. It combines ads as the captchas. Security and advertising combined–that could be in interesting twist for some.
