It looks like the trend towards wide spread retention of traffic analysis data is spreading to Ireland, one of the last holdouts in Europe. If you want to be protected from this kind of data gathering, you need to take proactive precautions. From the SANS institute:To satisfy the requirements of a European Union (EU) directive,Ireland will begin retaining records of its citizens' emails and Internet chats. While the content of the communications will not be retained, records of the IP addresses of the participants, the time and date of the communication, and the physical size of the message would be stored. The plan would take effect within one month through a statutory instrument in lieu of introducing legislation in Parliament because the country has received notice from the EU that it is three months overdue in implementing a data retention plan. A civil liberties organization has voiced its opposition to the plan as well as the way in which it is being implemented.The group maintains that law enforcement officials will be permitted to access the retained data without court orders or warrants.
