How Good are Humans at Solving CAPTCHAs?

A Large Scale Evaluation

A study recently released by Stanford researchers shows that traditional CAPTCHA tests (the kind that force users to decipher warped and distorted text) used on the most popular websites today are difficult for humans to solve. Many CAPTCHAs took up to 15 seconds for a website visitor to solve and were only 70% accurate. Audio CAPTCHA tests that play garbled sounds were even more difficult for people, achieving only a 30% accuracy rate. Half the users in the study simply abandoned the audio CAPTCHA.

With more than 200 million CAPTCHAs being solved on the Web every day, that's a lot of wasted effort and high failure rates for people wanting to interact on a website or make a purchase online.

No wonder website visitors are so frustrated with traditional CAPTCHA methods and often abandon the task. Confident CAPTCHA provides website owners, bloggers and online businesses with a better solution that improves the user experience and reduces website abandon rates while increasing security.
