Minneapolis police are making changes to protect the sensitive information in their massive vehicle tracking database from possible misuse by stalkers and others.
The city's database is filled with location information collected by small license plate readers mounted on squad cars and bridges, logging data on every plate they spot in the hope of finding wanted vehicles.
Since the data is classified as public, anyone can request location information on someone else's car -- provided they know the license plate number -- and find out where it has been seen on a handful of days.
The city used to keep that data for a year, but now discards it after 90 days. That's still longer than St. Paul, which keeps data for two weeks, and the State Patrol, which discards it after 48 hours.
Minneapolis police are working to create an audit system to track access, as well as department-wide policies governing when the information can be searched and by whom. Interim Chief Janeé Harteau is also seeking a state law change to keep the information private, which would allow vehicle owners to see only their own data. The Legislature is likely to take up the issue next year.
Since the Star Tribune first reported in August on the availability of the license plate data, the Minneapolis Police Department has received nearly 80 such requests, including one from a man who said he has hopes to "create value" from the entire database.
Arthur D'Antonio III, who works in Web startups in Southern California, is one of at least two people who have requested the entire database from the department. He declined to get into specifics about why he wants the information.
"What we're looking to do is create value," D'Antonio said. "So I don't want to put people in harm's way by any means. But the data is out there. And so there are a lot of valuable uses from demographic information through to basic analysis or even actionable repo men use cases. So wherever the value is, that's where we'll go."
