that is an online drm...i would need to connect to the interent for that to work and Sony has stated you can play the ps4 OFFLINE. im talking completely offline...meaning used games would work because there is no authentication that can go on if you are playing single player

You can require authentication via codes over phone ala Windows/Office.

Yes, but it needs online to register with the company, so no one else can use the said products authetication code again.
