Short for High-bandwidth Digital Content Protection, HDCP is a protection scheme developed by Intel. It is used to keep all audio and video content traveling over DVI, DisplayPort, and HDMI, from being copied or otherwise duplicated.

HDCP three security measures

  • Authentication stops content from being sent to devices that are not licensed.
  • Data sent over any of the appropriate cabling is encrypted.
  • Devices that are compromised have their keys revoked and are no longer able to receive data.
