Clever Workaround: Visual Cryptography On Austrian Postage Stamps 74

An anonymous reader writes Have you heard of personalized postage stamps? You pay the value of the stamps plus a fee and the post office prints official stamps usable for postage which show (almost) anything you can put into a jpeg file. An Austrian Tibet supporter found out what 'almost' means. He submitted a picture of the Dalai Lama with the text 'His Holiness the Dalai Lama,' but the Austrian post office refused to produce these stamps. Stampnews and the Neue Zuercher Zeitung (autotranslation) reported that this had been due to pressure from the Chinese embassy in Vienna. Now there is a video showing how visual cryptography has been used to get around this attempt at censorship [caution: organ music] .

    It says

    HH THE
    DALAI
    LAMA

    when you overlap the two stamps (and it's pretty difficult to see that). That's neat and all, but you would have to know to remove the stamps, remove them cleanly, overlay them, and shine a light through them to even see it. And there's no message at all if you have only one stamp. I think the censorship was still basically achieved.

    Is it a slow news day? The two linked articles are from years ago and don't actually mention anything about this design your own stamp attempt.

    Most places won't allow you to generate products like these stamps with pictures of famous people on them as they don't want to get sued by said person. Royal Mail definitely won't as they've got two explicit rules that cover it so should be start screaming about censorship there also? "2.2 you have obtained the permission of any person (or their parent or legal guardian) who appears in the material, for their image to be reproduced." and "4.5 it promotes any particular religious beliefs or may offend against any person’s religious beliefs;"

    Anyway, does it even count as getting around censorship when you need to do something obscure to see the result? Just writing under the stamp would have been easier and much easier to read than the final result. This is like a schoolkid method of trying to get one up on somebody else. "Tee hee. They don't know that if you combine my two stamps then you get something that they don't like!"

    why the fuck did the austrian post office ask the chinese embassy if it was OK to print these stamps?
