  Privacy and cryptography 

A few simple definitions on privacy and cryptography
Sweden passes sweeping law to allow monitoring of any communication passing its borders, without need of suspicion of crime, and without informing monitored individuals.
Text of the agreement between USA and Sweden "on cooperation in science and technology for homeland security matters" (interesting choice of words, isn't it?)
  - This seems to be the principal reason behind the above law.
Privacy in stored data - How safe and private is data stored on a hard disk? When is it really erased from a hard disk?
My position on privacy and cryptography - Personal reflections on the usefulness of and need for privacy in the context of Internet and personal computers.
Thought exercise: destroying a hard disk - You may wish to permanently destroy the information contained on a hard disk that is no longer need. How would you do it in practice?
Thought exercise: destroying a memory card - Memory cards often contain personal information. How do you permanently destroy this information with practical methods and no need of special equipment or software?
