The European Commission proposed expanding its criminal data bank system on Wednesday to help countries exchange more information on terrorism, cross-border crime and undocumented migrants.
The proposed changes to the Schengen Information System (SIS) include facial imaging and palm prints to identify people entering the Schengen area and adding alerts on people denied entry and those whom EU member states say should be sent home.
Border security has moved up the EU agenda in recent months after it was revealed that suspects in the recent terrorist attacks on Paris and Brussels moved freely across Schengen borders last year.
"In the future, no critical information should ever be lost on potential terrorist suspects or irregular migrants crossing our external borders," EU Migration Commissioner Dimitris Avramopoulos said in a statement.
"SIS is only as good as the data inputted into it," EU Security Commissioner Julian King said.
If adopted by member states, the new regulations would likely not take effect until 2021, after technical and legal arrangements were made in the member states, the commission said.
SIS, set up in 1995, is a data bank that stores alerts and information on wanted persons or objects.
Consulted 2.9 billion times in 2015, SIS is the most widely used information sharing system for border management and security in Europe, according to the commission.
The system contains 70 million entries with photos, fingerprints and other data to identify persons who have no right to enter or stay in the Schengen area and those sought in relation to criminal activities.
