In case you missed it, there was an article in the New York Times today (requires subscription) about “Making Digital Data Self Destruct”.
It reminded me why I hate popular media coverage of science. First, the article doesn’t give any explanation of what is going on. (The best I could figure was that the system involved an application of standard secret sharing techniques.) Second, it demonstrates once again that media coverage of scientific results is driven by PR rather than by any inherent scientific (or even economic) value of the result itself.
