Cognitive Blind Blockchain CAPTCHA Architecture

CAPTCHAs are a safe bet because they are used by so many other websites. They minimize risk from websites simply by integrating them. However, repeating that CAPTCHA creates a bad user experience and spends millions of hours of human brain cycles to resolve recurrent CAPTCHAs is meaningless. Furthermore, because CAPTCHA providers target users with advertising, some consumers have expressed worries regarding privacy promises. We also ran into problems in nations where CAPTCHA services were occasionally unavailable. As a result of productivity, blocking, and privacy concerns, numerous academics have pondered building new CAPTCHA architecture over the years. Rather than seeking to replace CAPTCHA with a single alternative unilaterally, we developed an adaptive blind CAPTCHA architecture that improves both individual and organizational privacy and efficiency while still permitting interoperability with existing CAPTCHAs. Based on blockchain and blind token technology, this solution protects users’ privacy and sensitive data while simultaneously delivering high usability, quick deployment, and protecting online services from automated harmful bots.
