Friendly Captcha does not depend on tracking your users and exploiting personal data. Plus, your users no longer have to deal with tedious labeling tasks. They don’t have to do anything at all.
Cryptography made simple
Experience Friendly Captcha yourself.
Friendly Captcha is a proof-of-work based solution in which the user’s device does all the work.
