The attacks in Paris in November that killed 130 people have focused the spotlight on the cooperation between countries in fighting a growing threat.
The gunmen and suicide bombers who brought carnage to the streets of the French capital had travelled from Belgium, and many were already known to the intelligence services.
Juergen Stock, the head of international police agency Interpol, told the annual meeting in the Swiss ski resort: "We need to be better not just in sharing but also in sharing specific information.
Interpol has amassed around 6,000 profiles of people earmarked as terrorists and the challenge now is to use technology to allow the regular policeman on patrol to have rapid access to the information, Stock said.

"It is important that this information is available not just at the level of specialised units but also at the level of police station and patrol officer, in his car and in the street," Stock told a security forum on the final day of the Davos conference.
The director of Interpol's European counterpart, Europol, told AFP in an interview that intelligence cooperation had already improved since the attacks in Paris, which were claimed by the Islamic State group.
"It establishes for the first time in Europe a dedicated operation centre," Wainwright said in Davos.
French investigators believe the attacks that killed 130 in Paris were planned by a Belgian national, Abdelhamid Abaaoud, who was widely thought to have been in Syria fighting with IS.
The apparent ease in which Abaaoud slipped back into Europe and moved around the continent has thrown into question the intelligence sharing capabilities of EU police forces.
