Cloudflare, a provider of DNS and DDoS protection systems, has unveiled the Cryptographic Attestation of Personhood. This is a key-lock system that allows you to get rid of annoying distorted pictures. But to use CAP, you need a USB key from the list of supported ones.
The main task of the CAPTCHA is to confirm that a person is using the site or application, for which the choice of certain images or the input of data from a distorted image was invented. But Cloudflare decided to go the other way: they made software that creates a unique encrypted key that the user will store on their encrypted USB drive.
The user only needs to press one button and select their key. The system will match the keys itself and let the visitor pass further. Now the company is working on expanding the list of keys, including not excluding the use of smartphones.
