An Explosion of Geofence Warranties Threatens Privacy Across the US
The police around countries severely increasing their use of geofence commands, a widely criticized investigative method that collects data from the device of anyone who is in a specific location within a specific time, according to new figures shared by Google . Law enforcement has been serving Google’s geofence warrants since 2016, but the company detailed for the first time exactly how much it will receive.
The report reflects those requests vomiting profusely in the past three years, it has risen to tenfold in some states. In California, law enforcement made 1,909 requests in 2020, compared to 209 in 2018. Similarly, geofence warrants in Florida jumped from 81 requests in 2018 to more than 800 last year. In Ohio, requests rose from seven to 400 in the same hour.
Across 50 states, Google’s geofence requests increased from 941 in 2018 to 11,033 in 2020 and now makes up more than 25 percent of all data requests the company receives from law enforcement.
A single geofence request can include data from hundreds of stands. In 2019, an order is relevant with fire resulted in nearly 1,500 identifying the device being shipped by the Bureau of Alcohol, Tobacco, Firearms, and Explosives. Twelve civil liberties groups and privacy advocates are present called for a ban the method, arguing that it violated the protections of the Fourth Amendment against unreasonable search, particularly by protesters. Today, Google’s transparency report reveals the extent to which people across the country may be facing the same violation.
“There’s always collateral damage,” said Jake Laperruque, senior policy counsel for the nonprofit Project on Government Oversight’s Constitutional Project. Because of their common breadth, geofence warrants can give police access to location data from people with no connection to criminal activities.
“We strongly protect the privacy of our users while supporting the important work of law enforcement,” Google said in a statement to WIRED. revealed. “
Just this week, Forbes revealed this Google provided the police in Kenosha, Wisconsin, accessing user data from those standing near a library and a museum that burned down in August, during protests following the assassination of George Floyd. Google handed out “GPS coordinates and data, device data, device IDs,” and time stamps to anyone at the library within two hours; at the museum, in 25 minutes. Similarly, Minneapolis police asked Google user data from anyone “within the region’s geography” in a suspected burglary at an AutoZone store last year, two days after the protests began.
Laperruque argued that geofence warrants could have a “chilling effect,” because people forgot their right to protest because they feared being targeted by surveillance. Just this week, Kenosha lawmakers are debating a bill that would make it a crime to attend a “riot”. Critics have argued that such a law could punish anyone who attends peaceful demonstrations that, due to the actions of others, have turned violent. Similarly, geofence data can be used as evidence of guilt not only by pitying others in a host but only by going first.
Geofence warrants work differently from typical search warrants. Often, officers identify a suspect or person with an interest, after obtaining an order from a judge to search the person’s home or belongings.
Using geofence warrants, police start with the time and location where a suspected crime occurred, then request data from Google for devices around that area at that time, usually within one to two hours. time window. If Google complies, it will provide a list of anonymous data about devices in the area: GPS coordination, time stamps when they were in the area, and an anonymous identifier, identified as a witness location difficulty, or RLOI.
