Most of us are savvy enough to ensure that our home and/or office wireless Internet connections are encrypted, thereby preventing other folks from sneaking on and using them while we aren't looking. On the other hand, it's amazing how many "unsecured" systems you see here and there.
Well, my old chum Alan Winstanley in the UK just sent me a link to a jolly interesting webpage as follows:
This tells the story of a guy who realized that his neighbors were accessing his wireless network. As he says: "I could encrypt it or – alternately – I could have some fun."
He then shows how he split his access into two halves. The one for accredited users (like himself) works "as-usual". By comparison, the one that his neighbors see automatically flips any images upside down before displaying them on the screen. Can you imagine the confusion this could cause, especially since they will almost certainly assume that there's a problem with their computer.
The author shows some examples of these upside-down web pages. Also, this cunning little scamp explains how – as opposed to inverting the images – you can simply "blur" the images that are displayed on the pirates' screens.
This is really rather clever. I would love to be a fly-on-the-wall watching the results...
