    A couple of things to try

    There are few white bricks around stormforge where you can get to stare directly at bright white brick (near the entrance to the palace and a couple of other places).

    Secondly, the edge detection in gimp does a VERY impressive job of showing these off (use prewitt compass at full) and then you can use the curves (under colours menu) to enhance (pull the curve to the top near the beginning):

    Reverse each byte before converting to ASCII. 10001100 00001100 -> 00110001 00110000

    Haha I realized that right after I posted, why is it Little-Endian though?
    Thanks for the help though!

    Read this guy's message and his following posts, and possibly pm him for some direct info. From his post, it seems that nothing is encrypted, you just gotta decode the message to begin with.

    If I remember right -> It is not allowed in Germany to get Process Information, so surely they have to remove it in Germany

    I don't think anyone's going to go to great lengths to try and do anything about it when it is so unclear whether it is even infringing any laws. Blizzard haven't even given a PR response.

Also, would not the encryption in the images live up to the required level of protection under the law, even if it was in fact "personally identifiable data"?

    I'd be curious to see what "openly gain your permission" requires? Do not the terms of the EULA and TOS achieve that?

    Finally, assuming the above two issues did not fall in Blizzard's favor, wouldn't it still not be a violation of the DPA since it was not Blizzard who has published this information, but rather the end users?
    Hello saillaw

    Just a few more comments on this. The information inside the watermark is not encrypted, it is just encoded. This means that as soon as someone figures out the algorithm to get them out from a normal image (we got half way there in 48 hours using a clean image) then they can extract the account id and realm id from any available screenshot on the Web (after 2008 apparently).

    Now, combine this with an automated Web spider bot which scans for images and categorizes them based on account and realm id, and you can quickly make a database showing which screenshots belong to which character and have the users identify who is who. Note that a website (cogshanks.org) which used the capabilities of the ignore list* to help users realize which accounts holds which characters, has now been disabled "because [of] heathens", as it states - whatever that means. I am pretty sure Blizzard wants to be the only one who knows who is who in the game.

    In addition to this, as soon as someone is able to successfully extract the full watermark from a normal image, they can then also re-encode it into a clean image This way they can use the Assembly code mentioned in this thread to skip the their watermark, screenshot themselves performing weird hacks or cheats and then embed the watermark of another character - which is like framing them for something they didn't do. Blizzard will then be checking the logs of the framed character to identify the hacks but they won't be finding anything (which will make them even more worried :P).

    If Blizzard had published this information back in 2008, users who wanted to maintain their privacy (not everyone does, unfortunately) would know better than publicly share their WoW generated screenshots on the Web. Now that we discovered these unencrypted data after approximately four years, we only prove that anyone could have already been using this "hack" already and just keeping quiet about it. It wouldn't be hard for Blizzard to encrypt the data using a strong private key so that only them could be able to read them (and it would still also be nice if we knew :P). This whole case was an accident waiting to happen and I wonder for how long Blizzard expected us to continue without noticing.


    * Apparently, if you ignore a character, you also ignore all the characters in his account which, if it's used correctly/widely enough, can eventually produce the full character list.

    Just a side note; Doing this is easy and doesn't need any image editing. Just change the account name in memory and let the client do the watermarking.

    This system existed already on the 2.4.3 client and its also on private servers enabled. I found out that the current time is being saved in form of "Hours/Minutes", this confirms again that this is an active working system not just some "JPG artefacts". Just make each minute a SS and you will see that one part small is changing each time, its not changing in less than 1 minute though.

    Surprisingly the realm name seems to be not saved (Not sure about realmlist yet), I made identical screenshots with different realm names but the saved information was exactly the same (Only the minute part changed after 20 secs as it should be).

    Thank you for your contribution. Can you please post some reference for this? It sounds very interesting.
