Prediction 28.5.2004:
Future does not look very good!
• V. 2003: Increase of garbage
• The dramatic increase of viruses and junk mail
• V. 2004: Deterioration of network infrastructure
• Attacks on infrastructure has increased
• V. 2005: Manipulation of content
• Systematic manipulation of content in Internet
• V. 2006: Internet collapses
• People and companies do not tolerate any more the load of garbage
• We don’t trust on the content on the net
• Malicious attacks on the network infrastructure deteriorate the usability of Internet
⇒ Internet will cease to be place to make business
⇒ We go 10...20 years back before the time of computer networks

• We have had always problems in Internet and it is still here!
• Internet is free and open
• Nobody controls it
• There is no single switch to turn Internet off

• Definition of Privacy
Privacy is the claim of individuals, groups, and institutions to determine for themselves, when, how, and to what extent information about them is communicated to others. Alan Westin 1967

Identification problems
Helsinki University
of Technology
• How to identify a person?
• Something
• what I know • password, PIN code
• what I have
• keys, credit card, passport
• what I am
• fingerprint, iris/retina, palm shape, dental records, DNA
• December 2004 in Asia:
• Who is/was this person?
• No common database in the world on fingerprints, DNA, dental records,etc. • And are people willing to give all information to Big Brother?
