#2...or just use steganography. Steganography in videos can be made to be invisible to the naked eye, and extremely robust - even to video compression. It's also difficult to detect, and even more difficult to remove/tamper with.
What the author of the article is proposing is actually a kind of steganography, albeit a rather crude one, and probably rather difficult to implement (since scene timings will be different for each episode, and you'll need to keep a separate log of exactly which timings correspond to each person you've distributed the file to), compared to running a video through a process that embeds a steganographically hidden id pattern at each keyframe.

#3I guess we all agree that watermarking the viewable content instead of thinking about securing/signing the whole data file was not so smart in the first place.
When I download a video from the Google Play Store I can only watch it for 24 hours or so. I thought there was already a highly protected digital signature/encryption system involved. Why is that not used for reporter previews?

I'm surprised they just send out DVDs with content... HBO have a streaming service, creating a preview section shouldn't be hard. Up to reporters to get a decent connection to stream...

#5Not very clever.
Get two leaked copies, and mix them up. Use the credits from copy A, or hell, even chop off 11 milliseconds from them. Then mix and match scenes... even chop off a few ms from some randomly selected scenes.
I bet you wouldn't even need the two copies.

#6This must be one of those posts you only understand after you've been primed into some obscure context.

How will that survive transcoding? What if you bump it down to 477p resolution?
Re: Game of Thrones leak and watermark: a stupid tracking system
#8> and the only tracking set up HBO seemed to be a watermark in the bottom left corner of the screen.
If they only had the one obvious watermark, I think HBO was hoping that maybe the people getting the screeners would think that there is more than one way they had the video tracked. Either the person who uploaded didn't care, or didn't think about it.
Its worth noting HBO has been on a path to make content available on the internet even without Cable (HBO now). probably a good long term strategy. There are always people who want it sooner, and free!
This is why we can't have nice things..

Wouldn't a simple re-encode break any sort of stenography?

Of course we have no idea if they used steganography or not, right? He bases the article on the idea that they have no tracking info except the watermark, but I don't see any evidence that they don't know more.
