US President Barack Obama is getting ready to file a legislative proposal that would affect the National Security Agency's (NSA) data collection method, according to a New York Times report cited by VentureBeat.

The said proposal would prevent the NSA from getting hold of phone data unless they are able to retrieve an authorization from the Foreign Intelligence Surveillance Act (FISA) court for each phone number in question. They would have to present proof that the numbers they want to investigate are indeed lined to terrorism, the report explained.

As of now, the NSA has a five-year period for keeping phone data. Obama said this program will go on for at least another 90-day cycle, but a new scheme to stop this program is already in the works, The Verge stated.

Obama issued a March 28 deadline for the intelligence community to come up with a program that would meet his administration's goals. A reform panel from the NSA and a government watchdog agreed that the program ought to be halted, as the NSA's bulk phone data collection method was illegal, the report explained.
