I just don't understand how they can be expected to provide this, though. This "authentication technology" might not even exist, and in any case is very likely to be wildly different from the editing tech. The editing tech in the OP is also off-the-shelf components, i.e. nothing was invented, just assembled in to the correct form. What exactly are they supposed to have done, just not posted anything about it until they found a way to thwart the technique they just discovered? Most likely this bottoms out in an arms race, so they'd be waiting forever. Your request seems really absurd and I've never seen technological innovation work like this.
