I would like to raise the problem of the security of electronic mail. The problem popped into my mind a while ago, while reading about Italian legislation on the privacy and, in particular, of paper mail. I always wanted to draw the issue to the attention of the ``hi spheres'', but I am now in the UK, and the whole thing went into the limbo. The problem is simply as follows: there is no legislation that enforces the privacy of electronic mail. On the practical side, there is no software method currently implemented at large that allows the receiver, and only the receiver, to read his/her own mail. The secure transmission of mail is part of the whole process. The similar issue can easily be extended to the Internet, where sites (from the very client to the very server) can record your preferences, as if there were a big brother that spies on you and writes all down. An immediate consequence of it are all the SPAM mail selling financial services...
