Certified Output Protection Protocol (COPP)

Certified Output Protection Protocol (COPP) is a device driver technology that uses logo identification to deny access to video outputs or recordings. It was developed to prevent unauthorized digital video applications through developed security technology. Microsoft has encrypted control signals to ensure this type of protection. There are three protection mechanisms, and any graphics adapter must support one of them. This protocol securely connects between the graphics driver and the communication channel. The primary purpose of this security measure is to block unauthorized users from streaming protected audio and video.
