CAPTCHA Identification as an accessibility service in cloud

Nowadays, CAPTCHA technology is widely used to differentiate computer and human on the Internet. Many websites use CAPTCHA for their registration or login process, which blocks visually-impaired or blind users from accessing the resources that they need online. Although there are speech recognition and audio CAPTCHA that can serve as a workaround for visually-impaired users, these methods are adopted by very few websites. Most websites' CAPTCHA design do not take into account visually-impaired or blind user's difficulty with CAPTCHA issues as more accessibility support often means more cost.

Currently, there are about 5 million blind and 12 million visually-impaired people in China and many more around the world. The disclosure aims to help the visually-impaired people overcome the CAPTCHA accessibility issue by introducing CAPTCHA Identification as an accessibility service in cloud.

A common solution for most visually-impaired or blind users at the moment is to leverage the limited human resource around, such as asking relatives, friends or some charity call center services for help. It's nature to leverage human resource to pass CAPTCHA Identification as CAPTCHA was designed to determine whether a user is human or machine. However, help might not always be available nearby and manual call center services could be costly as the labor cost is growing.

This disclosure introduces CAPTCHA Identification as an accessibility service in cloud, whichleverages a huge volunteer resource pool to help blind users break the barrier to pass CAPTCHA Identification. The service is shown in the following picture:
