A growing number of cameras — hundreds around Los Angeles, thousands nationwide — are engaged in a simple pursuit: Taking pictures of license plates.
The digital photos, automatically snapped by cameras mounted on cars and street poles and then tagged with time and location, are transmitted to massive databases running on remote computer servers. Cops can then search those databases to track the past whereabouts of drivers.
Law enforcement officials say the data collection is invaluable for tracking down stolen cars and catching fugitives.
But such databases are also being built by private firms, which can sell access to anyone willing to pay, such as lenders, repo workers and private investigators. That is raising worries among privacy advocates and lawmakers, who say the fast-growing industry is not only ripe for conflicts of interest but downright invasive.
“What they’re doing crosses the line,” said state Sen. Jerry Hill (D-San Mateo), who is pushing legislation to rein in the industry.
Hill agrees that license plate data can aid law enforcement, but believes that the industry needs restrictions. He said he’s worried that partnerships between police and for-profit data firms could result in cops doing the bidding of insurance companies and repo firms.
His legislation would ban public agencies from sharing data they collect with private entities, prohibit license plate scanners from coming onto private property without consent and make it easier for privacy lawsuits to be filed against data collectors.
To demonstrate the power of the databases, Hill hired a private detective to track his wife. Rather than tailing her, the detective paid for access to license data that showed Hill’s wife parked at a Sacramento gym more than 100 miles from their home.
