If you’ve been online, during the past 10 years, inevitably you’ve run into CAPTCHA or better said you may have had a run in with CAPTCHA. When I first encountered CAPTCHA, I didn’t have a clue why this addition problem was there so I ignored it, and the form ignored me too. Those annoying little boxes challenging your recollection of elementary math, have knowledge of Arabic or Hebrew, or get distorted character messages that make you wonder whether it’s totally random or personal.
CAPTCHA, also known as Completely Automated Public 우머나이저 Turing test to tell Computers and Humans Apart, was invented to ensure only humans were entering data into the entry fields and not a computer program. I utterly despise SPAM and to stop receiving it on my website I implemented CAPTCHA. This essentially eliminated the problem, but it also had an unwanted side effect of dramatically reducing the number of comments I received. A study was conducted which confirmed my opinion – CAPTCHA impacts some people’s ability/willingness to follow through on completing it.
Some CAPTCHA facts:
- Each CAPTCHA takes about 10 seconds to complete.
- Roughly 200 million CAPTCHA is completed daily.
- About 500,000 hours or the equivalent of 62,500 man days are spent daily completing CAPTCHA; hours are essentially wasted.
