ABSTRACT
In 1993, Peter Steiner published a cartoon in the The New Yorker∗, which illustrated a dog communicating over the Internet. The caption of this cartoon appears to be extremely prophetic for the Internet community, since it asserted that “On the Internet, nobody knows you are a dog”. Actually, as far back as the early 1990s, this assumption was somehow valid, mainly because the communication intermediates or relays, did not care, worry, or ask if the enduser was actually a dog or a human. Nowadays, end-users, mainly humans, should employ technical and procedural means to defend against attackers that maliciously survey or spy on the Internet using network traffic analysis tools. This will protect the personal freedom and privacy, achieving digital dignity, and, moreover, defend confidentially in business, as well as in human relationships. That is why today we should say “On the Internet, nobody should know you are a dog”.
