Microsoft and Xbox One is taking a lot of heat for its online DRM. Microsoft may have done this as a cash grab but it does seem like, more and more, this DRM push is coming from the publishers. If this is true, and Sony will need DRM for publishers to put out games on the PS4, how could Sony's DRM look?
Let's look at what we do know. Sony has said the PS4 will not be always online and will not have an online DRM. So end of story, no DRM, we get used games and all is right with the world. Well as college football analyst Lee Corso would say, not so fast my friend! As we learned about early this year, Sony United States Patent Application US20130007892, Sony's technology would check a game disc's RFID tag, which is capable of remembering if that game had been linked to a different machine or account. This check is performed offline and before the game is played. So once a game is placed in a PS4, it is locked to that system and cannot be used in a different PS4.
If Sony has to have DRM in the PS4 because of the publishers, I would think this is how they plan on doing it. And if this is true will Sony have a system for used games at all? Any other ideas?
