Since the beginning of 2008, a new law gives the German federal government broad access to stored telephone and Internet data - including e-mail addresses, length of call and numbers dialled - for a six month period. The private initative "Arbeitskreis Vorratsdatenspeicherung" called for a class suit against the new law. But how can you make people believe how many traces they leave when surfing the Web?

Launched in 2008, the "Fingerprint" project may be able to fuel the discussion about privacy on the Internet and raise awareness for the issue.

The sheer number of 30,000 participants that joined the class suit of the Initiative at the German Constitutional Court clearly demonstrates the public interest.

Through widespread discussions in the press, most users don't realise what kind of data and to which extent they leave behind when surfing the Web. A special programme visualises the digital fingerprint of every user. The fingerprints lead the user to a landing page and to special browser for anonymous Web surfing.

Most Internet users are not aware to which extent their surfing habits are traceable. At the same time, the Web is the perfect place for appealing to new members for an existing movement.
