CBNNews.com - JERUSALEM, Israel - US Homeland Security Secretary Michael Chertoff said America can learn from Israeli airport security procedures.

Chertoff is in Jerusalem this week to attend an international conference on homeland security.

"Not every technological approach here [in Israel] is necessary applicable, but we are always open to look for technology from whatever source," Chertoff told Reuters.

One particularly adaptable technique used at Tel Aviv's Ben Gurion International Airport is behavior-detection technologies.

"That's a scenario where Israel has a lot of experience. I think that it is of interest to us to see if there is any adaptation there," he said.

A new system presented at the conference, developed by WeCU, an Israeli technology firm, combines behavioral science with biometric sensors to spot potential security risks among airline passengers.

Israel's highly developed technologies for detecting explosives also interested Chertoff.

"The challenge will be to keep moving forward. We need to continue to implement the measures we have in place and continue to look for additional things to match what the enemies are doing because they are constantly retooling themselves," Chertoff said.

Chertoff said Israel's practice of interviewing every passenger was impractical at America's major airports due to sheer numbers. While Ben Gurion processes some 9 million travelers annually, Chicago's O'Hare airport sees 76 million passengers a year.
