SIE patents a controller with a CAPTCHA system in it for security, check out the description:
A CAPTCHA is presented on a display and a user of a hand-held controller such as a computer game controller is prompted to respond to the image. A correct response entails manipulation of a key on the controller and does not require input from an alpha-numeric keyboard.
DualShock 5 touchscreen potentially? I am not sure what this really means here.
