Germany’s Chaos Computer Club has announced the theme for their annual Chaos Communication Congress: “Nothing to hide“. Like last year’s “Full steam ahead!“, it’s open to many interpretations. People striking down privacy laws often say citizens shouldn’t mind since they have “Nothing to hide”. The phrase is also connected to the inability to hide data, as the CCC demonstrated this year by publishing the German Home Secretary’s fingerprint. On a more positive side, “Nothing to hide” is also about the free exchange of information that happens at hacker conventions. The Congress is in its 25th year and promises to be as good as ever. At last year’s 24C3, we saw great talks like [Drew Endy]‘s biohacking talk and the original MiFare crypto presentation. 25C3 will be held in Berlin December 27th to 30th. The wiki is already up and they’ve published a call for participation, if you’re interested.
