cAPTCHA: THE ENEMY?
Something that everyone who has signed up for anything online has seen is a Captcha. A Captcha is a series of letters and numbers that are written in a skewed pattern that allows the user to verify that they’re human. Aside from the fact that they have been proven to be useless, and can be cracked by computers, there are also some humans who cannot use Captchas. The Captcha’s filter allows some advanced computers, and denies some impaired humans, thus deeming the whole process useless. For someone who has trouble seeing, the process is nearly impossible. Should someone who has impaired vision be completely denied basic access to thousands of online opportunities?
Personally, I can think of numerous times when my Internet use was slowed because I was caught at a Captcha. I most constantly see them/ are frustrated by them when buying concert tickets. When stuck at a Captcha in this situation, tickets are selling out elsewhere. With this being said, if someone whose sight was less than perfect tried to buy a ticket, it's possible that someone with perfect vision could purchase the tickets quicker.
Facebook, the most popular social networking site in the world, also makes use of the Captcha. This automatically impedes people who have trouble seeing from creating a Facebook and connecting with their family and friends.
Is there another way for computers to verify that someone is human that is more user-friendly?
