In an attempt to get more oversight, the Justice Department said Thursday it will seek more judicial and internal supervision as it uses technology to track cellphones, the Wall Street Journal reports. 

In the past, technology was kept a secret, drawing criticism from privacy advocates, judges and lawmakers.

At issue are cell site simulators, which enables investigators to secretly scan phones.

Under the changes, supervisors would be required to more closely examine the use of the devices. Data collected on innocent Americans also would need to be deleted at least once a day.
