COLUMBUS, Ohio - An American Civil Liberties Union report on police departments' increased use of license-plate scanning notes that the scanning policy of the State Highway Patrol in Ohio is more protective of privacy than some.
The report released Wednesday found scanners affixed to police cars, bridges or buildings around the country capture license plate images providing records of people's location and movement. That information often goes into databases that can be reviewed much later.
The ACLU says the Ohio patrol's policy calls for rapid deletion of such information if it doesn't raise concerns and says it can't be collected, stored or shared with the intent of mining data.
The patrol says it takes precautions to protect people's privacy from information collected by the agency's 20 plate scanners.
