The Intel(R) Content Protection HECI Service is used to enable premium video playback (such as Blu-ray*) for Intel® HD Graphics. It does not collect any user information. Disabling the service will prevent certain types of premium video from playing on the system; however, unprotected video such as user-generated content and YouTube* videos will continue to play.
You can disable them, with no loss imo unless you use Blue-ray as all other video's are probably Internet based / flash
