Wenn verschiedene Gruppen gemeinsam ein KI-Modell trainieren wollen, müssen sie ihre Daten schützen. Eine Möglichkeit besteht darin, den Berechnungen zufälliges Rauschen hinzuzufügen, sodass niemand erkennen kann, welche Daten von wem stammen. Dafür gibt es zwei Hauptansätze: Entweder fügt jede Gruppe ihr eigenes Rauschen hinzu – was viel Rauschen erfordert und die Ergebnisse weniger genau macht – oder das Rauschen wird gemeinsam in einer sicheren Berechnung erzeugt. Letzteres erhält die Genauigkeit, war bisher jedoch sehr langsam und kommunikationsaufwendig.
Die Forschenden stellen nun eine neue Methode vor, um dieses Problem zu lösen. Anstatt das Rauschen auf komplexe Weise zu berechnen, schlagen sie vor, es aus vorberechneten Tabellen zu entnehmen, die die benötigte Zufälligkeit annähern. Dadurch wird der Prozess wesentlich schneller und der Kommunikationsaufwand sinkt. In ihren Experimenten war die neue Methode über 200-mal schneller als frühere Ansätze und funktionierte auch bei vielen Teilnehmenden zuverlässig. Zudem ist sie flexibel und kann für verschiedene Arten von Rauschen eingesetzt werden.
Für die Gesellschaft bedeutet das, dass sichere Zusammenarbeit mit sensiblen Daten einfacher wird. Unterschiedliche Organisationen können gemeinsam KI-Modelle trainieren, ohne private Informationen preiszugeben – und dabei dennoch eine hohe Modellgenauigkeit erreichen.
