Proposal: How to do DRM
|
|
"The customer needs to experience the software first-hand without reduced functionality during the trial" is a phrase that Microsoft uses on several marketing sheets. What that means is that trials should only be limited by time, not in WHAT you can do during that time. That got me thinking....

Excerpt:
Of course, security needs to be tightened down on the actual preview-mode DRM wrapper so that people can't easily crack it and get free music, but there are extra methods to ensure that - TPM modules and "encrypted audio path". "Encrypted audio path" is the term I've coined (at least, I've never heard it used before) to imply a protection system wherein the audio stream is completely encrypted up to a speaker connection, much like the way it's employed with HD DVD/BluRay on Windows Vista. This needs to be implemented at the driver level also, to prevent "stream copying" (sorry, but I'm still trying to stay legal with this). This is a REQUIREMENT by those governing bodies, and although people are upset that it requires new HDCP-compliant hardware to get it to work, it is not something that Microsoft had a choice over - if they didn't comply, they couldn't support either standard. Sorry, but it's true, and Microsoft isn't "evil" over this, unlike what the folks at BadVista.org would like to think. If Linux and/or OS X ever supports either format, to do it legally, they need to do the same thing. I'm sure Sony or Toshiba, etc. would have no qualms in pursuing legal action over someone that didn't follow their policies too.
Let's be civil and point out the flaws in this proposal without ranting - jhansonxi
