My Conclusions

1. It is very likely the Bytecoin website hosts the genuine whitepaper.

2. The whitepaper published on CryptoNote's website may be a forgery. There is no PGP watermark and the author's PGP public key can't be used to validate the whitepaper.

3. Someone has duplicated the genuine whitepaper line by line for them to look the same - but failed at capturing some of its hidden elements.

4. Now let's move to whitepaper v.1 on CN website. As there is no signature to validate this whitepaper, the only relevant test is watermark. If it's inside, then the asumption on CryptoNote's conspiracy may hold. However, whitepaper v.1 doesn't have this watermark.

5. The problems with latex compilator problems, XMP meta tags, and invalid links may point to a forgery attempt, not van Saberhagen's actual activity.


Unclear questions for further research

1) What and why did we find two strange whitepapers on the CryptoNote website? A number of options may be valid. I assume it could be a mistake, a social engineering trap, hacked website or someone's attempt to discredit the technology? Who knows.

I'll point CryptoNote that they may have a wrong whitepaper. Maybe they will care to comment or take actions.

This is really good analytical research about the whitepapers.
There are indeed 2 possibilities here (IMO): It was a genuine mistake from the CN website (not really 100%, on this one) or it was a malicious act to try discredit the technology itself. Lets not forget that when competitors consider you  a threat and to their own interests, they will go in all lengths to discredit you.
