Deep dives
The Genesis of CAPTCHA
CAPTCHA was developed to distinguish between human users and bots, initially addressing issues like spam account creation on platforms like Yahoo. By designing tests that are easy for humans but challenging for computers, CAPTCHA effectively prevents automated registrations. This innovation stemmed from a challenge presented by Yahoo's chief scientist, which highlighted the need to stop bots from obtaining vast numbers of email accounts. Ultimately, this led to the creation of distorted text tests, as they leveraged human ability to interpret images while computers struggled with this task.
