Once online-only media becomes common (or even slightly before), I wouldn't be surprised at all if encryption of this type is used for each individual movie purchase.ROclockCK said:I'm somewhat uneasy though over the implications of this...I mean, "Why would 'Net access be required for playback?" Or in a worst case, "Could this disc and its content be disabled remotely at some point unless I purcha$e a new encryption key?" Or, "Is this simply another type of DRM for hard media, intended to thwart unauthorized ripping/copying?"
ie. A different key for every different customer.
The easiest implementation of such a system, would be a public key type system.
