A rift has appeared between the president and senior industry figures over his calls for them to hand over more data.
According to a White House statement, the President would sign an advisory executive order encouraging the setting up of information sharing and analysis organisations (ISAOs) to help firms and government to share material on potential threats.
It will also develop a common set of voluntary standards for the organisations to follow, including the protection of civil liberties, the White House said.
