Local police departments across the US have purchased a tool that allows them to monitor individual devices without a warrant based on data collected from common apps smartphone που είναι εγκατεστημένες στα τηλέφωνα του κόσμου, σύμφωνα με έρευνες της ακτιβιστικής οργάνωσης Electronic Frontier Foundation (EFF) and her Associated Press.
Motherboard published today the user manual of the tool, called Fog Reveal. Bennett Cyphers, an EFF staff technologist who worked on the investigation using public records requests, provided the manual to Motherboard.
The paper describes a technology that was relatively unknown until recently and is being used by local police departments in many different investigations. The Associated Press he even mentions that although the authorities use the tool very often, the prosecutors "rarely, if ever" do not disclose its use in the relevant case files.
"Our handbook shows how the police can access and use our data. It shows how easy it is with one click to track arbitrary people with Fog Reveal. These files should be public by default so the public can hold surveillance companies and law enforcement accountable," Cyphers told Motherboard.
Virginia-based Fog Data Science is the company behind the Fog Reveal tracking tool. The Associated Press reports that Fog Reveal lists a company called Venntel as a "data partner," but neither company would specify their relationship.
However, Venntel is known to source global advertising data from its parent company Gravy Analytics. The data comes from apps installed on people's smartphones. App developers often enter into agreements to sell the information locationς των χρηστών τους σε τρίτους. Στη συνέχεια, η Venntel πουλάει τα δεδομένα σαν product επιτήρησης σε κυβερνητικές υπηρεσίες.
Fog Data Science, meanwhile, appears to be focused on providing similar services to local and state law enforcement agencies, according to EFF and Associated Press investigations.
The Fog Reveal user manual states that “Information that was previously “unknown” or known only through the investment of significant time in efforts such as interviewing witnesses, reviewing surveillance video, and travel records can be revealed in minutes via a desktop or laptop computer. "
After first logging into the tool it's apparent how simple it is for a user to start searching for old but recent data on what devices were in a certain area through a search box that accepts latitude and longitude coordinates and addresses. Users can also draw geofences to see which devices were in an area, with a rectangle, circle or custom polygon, according to the manual.
