In the latest wave of trans-Atlantic security measures, the United States and Germany have agreed to share data like fingerprints and DNA in what they say is a move to prevent terrorist attacks and to combat organized crime.

Under the new system of data exchange, each country can send fingerprints to be cross-referenced with the other's database.
