> Speaking at the Anti-Piracy and Content Protection Summit in Los Angeles last week, the chief technology officer at Sony Pictures said the pending arrival of 4K media players represents an opportunity to find new and better ways to combat piracy and protect IP rights holders. He called for "title-by-title diversity" so that cracking methods that work for one movie title won't necessarily work for others, "session-based watermarking" linking each downloaded 4K title with the device or user that downloaded it and HDCP 2.2-protected digital outputs.

> But what's particularly interesting in light of the recent kerfuffle over the Xbox One's now-discarded almost-always-on internet requirement and (Sony's crowd-pleasing rejection of such a system) is that Stephens wants to incorporate the same basic thing into media players. In his vision, 4K media players would have to authenticate online before every playback, which would make it relatively easy for content providers to clamp down on unauthorized content and hacked players, but would also cut consumers without internet connections out of the picture.

> Second, Stephens’s remarks had the flavor of a semi-public appeal to the community of content protection vendors — some of which were in the audience at this conference — for help in designing DRM schemes for 4k that met his requirements.

> Stephens’s wish list included such elements as:
> 
> 	• Title-by-title diversity, so that  a technique used to hack one movie title doesn’t necessarily apply to another
> 	• Requiring players to authenticate themselves online before playback, which enables hacked players to be denied but makes it impossible to play 4k content without an Internet connection
> 	• The use of HDCP 2.2 to protect digital outputs, since older versions of HDCP have been hacked
> 	• Session-based watermarking, so that each 4k file is marked with the identity of the device or user that downloaded it (a technique used today with early-window HD content)
> 	• The use of trusted execution environments (TEE) for playback, which combine the security of hardware with the renewability of software
