    Uber avoue utiliser un logiciel secret pour éviter les forces de l’ordre

    Uber, déjà montré du doigt dans plusieurs affaires ces derniers jours, a avoué vendredi l’existence d’un logiciel secret destiné notamment à éviter que ses chauffeurs ne soient contrôlés par les autorités. Uber a avoué utiliser ce logiciel surnommé « Greyball » après un article du New York Times qui en révélait l’existence.

      One technique involved drawing a digital perimeter, or “geofence,” around the government offices on a digital map of a city that Uber was monitoring. The company watched which people were frequently opening and closing the app — a process known internally as eyeballing — near such locations as evidence that the users might be associated with city agencies.

      Other techniques included looking at a user’s credit card information and determining whether the card was tied directly to an institution like a police credit union.

      [...]

      If users were identified as being linked to law enforcement, Uber Greyballed them by tagging them with a small piece of code that read “Greyball” followed by a string of numbers.

      When someone tagged this way called a car, Uber could scramble a set of ghost cars in a fake version of the app for that person to see, or show that no cars were available. Occasionally, if a driver accidentally picked up someone tagged as an officer, Uber called the driver with instructions to end the ride.
