The European Commission is proposing anti-terrorism measures that include the collection of extensive flight data and tighter internet laws.
EU proposals to collect passenger data mirror US measures
Under the plan, all 27 EU members would make recruitment, training and provocation to terrorism illegal.
The plan also provides for an early warning system if legal explosives are lost or stolen.
It criticises some countries for not doing enough to co-ordinate their laws after agreeing to do so five years ago.
The plan gives special attention to the internet.
Setting up web sites that encourage violence or explain how to make bombs would become a criminal offence.
The plan also focuses on air passenger data, requiring EU states to collect 19 pieces of personal information about people flying to or from member states.
The information would include a phone number, e-mail address and payment details, and would be kept on file for 13 years.
The collection of Passenger Name Record (PNR) data would bring the EU in line with the US, which introduced a similar scheme following the 9/11 attacks.
The measures would not apply to flights within the EU.
Critics of the European plan fear it would impinge on personal liberties, introducing unnecessary levels of surveillance.
"I find it unacceptable that in a democracy in the 21st century, that executive governments get unlimited and uncontrolled powers," Dutch Liberal MEP Sophie in't Veld said.
But the EU wants to reconnect with its often suspicious and hostile citizens by doing something that most people regard as worthwhile, says the BBC's Mark Mardell in Brussels.
Fighting terrorism is at the top of that list, says our correspondent.
EU Justice Commissioner Franco Frattini drew up the plan.
Announcing the proposals in Brussels, he said monitoring travel was a weak point in Europe's counter-terrorism strategy.
Passenger data is already collected for commercial purposes and should now be shared with authorities across the EU, he said.
All EU member states would need to approve the proposals for them to become law.
