That would remove their ability to take content away from consumers when contracts expire though wouldn't it?

- toomuchtodo 12y agoThe encryption keys would be time limited (monthly basis, certain titles, etc). If you don't top up monthly, you key expires, the underlying data is re-encrypted with another key, etc.
- joshschreuder 12y agoHow do you re-encrypt a read only storage medium like a disk though?
- fphhotchips 12y agoYou could have a master-key (or set of master keys) on a read-write medium, which you could encrypt/decrypt as many times as needed? You'd be vulnerable to someone scraping the master key from memory, but no more than someone just passing the video to a recording device.
- eru 12y agoTo be fair, they don't have that ability in the first place against a determined attacker. (Ie once they show you the content, you can grab it.)
- joshschreuder 12y agoYeah that's true, but I would say the majority of people aren't ripping Netflix streams in case Netflix's content licences expire. If they are given a master disk with everything on it, anyone with that disk has the data on it in perpetuity (barring storage failure)
